    Person-Centered Psychosis Care (PCPC) In An Inpatient Setting: Ward Level Data And Staff Workload2019In: Schizophrenia Bulletin, ISSN 0586-7614, E-ISSN 1745-1701, Vol. 45, no Supplement 2, p. S304-S304Article in journal (Refereed)
    Abstract [en]

    Background: The person-centered care approach has been little tested in inpatient settings for persons with schizophrenia. An intervention, PersonCentered Psychosis Care (PCPC), was created to increase person-centered care through an educational intervention for staff. The education had a participatory approach where participants were involved in shaping the education and creating projects aimed at care development. The PCPC intervention focused on the patient’s narrative, the creation of a partnership between the patient and staff, and on coming to an agreement between the patient and staff concerning the care. The present study aims to compare staff experienced workload and ward level data before and after implementation of the intervention.

    Methods: The study was carried out on 4 hospital wards (43 beds) at the Psychosis Clinic, Gothenburg, Sweden. Data was collected during a 6-month pre-intervention period, followed by an implementation period of 3  years, and finally a post intervention data collection period (9 months). During both data collection periods, one nurse per ward filled out a measure of daily subjective workload (a VAS scale with 0 indicating no burden at all and 10 indicating the highest imaginable burden). Additional ward level data (length of hospital stay, involuntary interventions, rehospitalization rates) were collected via the clinic’s electronic monitoring system.

    Results: The pre-intervention ratings (n=505) showed a mean subjective workload of 5.48 (SD=1.94). The post intervention workload (n=465) showed a mean of 4.51 (SD=2.08) which represents a significant reduction of experienced workload (t (968) = p <.0005). Analyses regarding length of hospital stay, involuntary interventions, and rehospitalization rates are underway and will be presented.

    Discussion: The findings indicate an improvement in the work environment for hospital staff and provide a quantitative result in line with staff experiences previously reported in our focus group study. The before and after design has its limitations, but the positive findings motivate further testing with a more rigorous design such as a cluster randomized study.

    Aloneness and loneliness – persons with severe mental illness and experiences of being alone2015In: Scandinavian Journal of Disability Research, ISSN 1501-7419, E-ISSN 1745-3011, Vol. 17, no 4, p. 353-365Article in journal (Refereed)
    Abstract [en]

    People with severe mental illness (SMI) are often described as lonely and socially incapable – an inability resulting from the mental illness. The aim of this article is to explore experiences of being alone among persons with SMI. The article is based on interviews with 19 persons diagnosed with psychosis who were interviewed between four and nine times over a period of three years. The findings show that experiences of being alone can be identified by two concepts: aloneness and loneliness. The persons in the study appeared as socially able and active in relation to their social lives. However, a social agent does not operate in a void but in interaction with specific living conditions; the experiences of aloneness and loneliness may be viewed as the result of the interplay between the individual and the social and material environment.

    A longitudinal study of men and women diagnosed with psychosis: trajectories revealing interventions in a time-geographic framework2019In: GeoJournal, ISSN 0343-2521, E-ISSN 1572-9893Article in journal (Refereed)
    Abstract [en]

    The living conditions for persons with severe mental illness have undergone substantial change in Sweden as well as in the rest of the Western world due to the downsizing of inpatient care and the development of community-based interventions. However, there is a lack of knowledge concerning the “trajectories of interventions” in this new, fragmented, institutional landscape. The aim of the study was to explore types of interventions and when they occur in a 10-year follow-up of 437 women and men diagnosed with psychosis for the first time. Based on registers and using a timegeographic visualization method, the results showed a great diversity of trajectories and differences between sexes. The aggregate picture revealed that over the 10-year period there were considerable periods with no interventions for both men and women. Furthermore, institutional interventions more commonly occurred among women but appeared for longer periods among men. Community-based interventions declined among women and increased among men during the period.

    Childhood Maltreatment Affects the Serotonergic System in Male Alcohol-Dependent Individuals2013In: Alcoholism: Clinical and Experimental Research, ISSN 0145-6008, E-ISSN 1530-0277, Vol. 37, no 5, p. 757-762Article in journal (Refereed)
    Abstract [en]

    Background: Reduced central serotonergic neurotransmission has been demonstrated in individuals with excessive alcohol consumption and/or alcohol dependence. Childhood maltreatment has also been found to have a negative impact on central serotonergic neurotransmission. The aim of this study was to evaluate the impact of childhood maltreatment on central serotonergic dysfunction in alcohol-dependent individuals.

    Methods: Adult men with a diagnosis of alcohol dependence (n=18) were recruited from outpatient treatment units for alcoholism. Central serotonergic neurotransmission was assessed by a neuroendocrine method, that is, the prolactin (PRL) response to the selective 5-HT reuptake inhibitor citalopram. Childhood maltreatment was assessed retrospectively by the Childhood Trauma Questionnaire.

    Results: Alcohol-dependent individuals with childhood experience of emotional abuse had significantly lower PRL response compared with those without such abuse (3 +/- 5 and 64 +/- 24mU/l, respectively; t=6.51, p<0.001). Among those who reported childhood emotional abuse, 4 of 7 individuals had flat PRL responses in comparison with none in those with no report of such abuse (p<0.01).

    Conclusions: This is the first study to show that self-reported childhood maltreatment, in particular emotional abuse, in male alcohol-dependent individuals is associated with a quite dramatic (more than 90%) reduction in central serotonergic neurotransmission. It should, however, be noted that the number of individuals is relatively small, and the results should therefore be considered as preliminary.

    Hazard perception skills of young drivers with Attention Deficit Hyperactivity Disorder (ADHD) can be improved with computer based driver training: An exploratory randomised controlled trial2017In: Accident Analysis and Prevention, ISSN 0001-4575, E-ISSN 1879-2057, Vol. 109, p. 70-77Article in journal (Refereed)
    Abstract [en]

    Background

    Young drivers with Attention Deficit Hyperactivity Disorder (ADHD) are at higher risk of road traffic injuries than their peers. Increased risk correlates with poor hazard perception skill. Few studies have investigated hazard perception training using computer technology with this group of drivers.

    Objectives

    *Determine the presence and magnitude of the between-group and within- subject change in hazard perception skills in young drivers with ADHD who receive Drive Smart training. *Determine whether training-facilitated change in hazard perception is maintained over time.

    Methods

    This was a feasibility study, randomised control trial conducted in Australia. The design included a delayed treatment for the control group. Twenty-five drivers with a diagnosis of ADHD were randomised to the Immediate Intervention or Delayed Intervention group.The Immediate Intervention group received a training session using a computer application entitled Drive Smart. The Delayed Intervention group watched a documentary video initially (control condition), followed by the Drive Smart computer training session. The participant’s hazard perception skill was measured using the Hazard Perception Test (HPT).

    Findings

    After adjusting for baseline scores, there was a significant betweengroup difference in post-intervention HPT change scores in favour of the Immediate Intervention group. The magnitude of the effect was large. There was no significant within-group delayed intervention effect. A significant maintenance effect was found at 6-week follow-up for the Immediate Intervention group.

    Conclusions

    The hazard perception skills of participants improved following training with large effect size and some maintenance of gain. A multimodal approach to training is indicated to facilitate maintenance. A full-scale trial is feasible.

    Hazard Perception Skills Of Young Drivers With Attention-Deficit Hyperactivity Disorder Can Be Improved With Computer-Based Training: A Feasibility Trial2017In: Australian and New Zealand journal of psychiatry (Print), ISSN 0004-8674, E-ISSN 1440-1614, Vol. 51, no Suppl. 1, p. 122-122Article in journal (Refereed)
    Abstract [en]

    Background: Young drivers with attention-deficit hyperactivity disorder (ADHD) are at higher risk of road traffic injuries than their peers. Increased risk correlates with poor hazard perception skill. Few studies have investigated hazard perception training using computer applications such as DriveSmart with this group of drivers.

    Objectives: To: determine the magnitude of the between-group and within-subject change in hazard perception skills among young drivers with ADHD-exposed/delayed exposure to DriveSmart training and determine whether training-facilitated change in hazard perception is maintained over time.

    Methods: Australian feasibility study. Twenty-five drivers with a diagnosis of ADHD were randomized to the intervention or control group. Participants in the intervention group received a computer training session using DriveSmart, while the control group watched a documentary video. The design included a delayed treatment for the control group. The participants’ hazard perception skill was measured on the University of Queensland Hazard Perception Test (HPT) post training and at 6-week follow-up.

    Findings: After adjusting for baseline scores, there was a significant between-group difference (p = 0.023, partial η2 = 0.212) and a significant within-subject difference post intervention in the experimental group. There was no significant difference between post intervention and 6-week follow-up scores in the experimental group.

    Conclusions: The hazard perception skills of participants improved following training and were largely sustained. We found a large effect size consistent with one prior study. A full-scale trial is feasible.

    Experience of psychotropic medication – An interview study of persons with psychosis2016In: Issues in Mental Health Nursing, ISSN 0161-2840, E-ISSN 1096-4673, Vol. 37, no 11, p. 820-828Article in journal (Refereed)
    Abstract [en]

    Psychotropic drugs, particularly antipsychotic types, are a cornerstone of the treatment of people with psychosis. Despite numerous studies showing that drug treatment with psychotropic drugs initially alleviates psychiatric symptoms, the proportion of people with mental health problems and symptoms that do not follow doctors' prescriptions, thus exhibiting so-called non-adherence, is considerable. Non-adherence is predominantly seen as a clinical feature and as a patient characteristic that is especially due to patients' poor understanding that they are ill. There is also a widespread notion that non-adherence is of great disadvantage to the patient. This article is based on interviews with 19 persons diagnosed with psychosis. It challenges the notion of patients being either adherent or non-adherent to the doctor's orders. The findings show that persons with psychosis are active agents when it comes to adjusting medication. The interviewees created their own strategies to gain power over treatment with psychotropic drugs. The most common strategies were to adjust the doses or take breaks of varying lengths from the medication. These deviations from prescriptions were important to conceal, not only from their own psychiatrists, but from all psychiatric staff.

    Working draft: Classifications of interventions in mental health care. An expert review2017In: European Journal of Psychiatry, ISSN 0213-6163, E-ISSN 2340-4469, Vol. 31, no 4, p. 127-144Article in journal (Refereed)
    Abstract [en]

    Background and objectives: Specific classifications of mental health interventions have encountered many issues in their integration into a general classification of interventions. Nonetheless, there has not been any previous review on the content and structure of current classifications in relation to mental health care. This expert review aimed to compare the mental health interventions provided in a series of reference classification systems for the incorporation of mental health care into the International Classification of Health Interventions (ICHI).

    Methods: Twelve classifications are described with regards to the structure of the classification (unit of analysis, sections, multiaxiality, granularity) and context of utilization (purpose, descriptors, neutrality, interoperability and implementation).

    Results: Major problems identified include a granularity unbalance (i.e. differences in the number of codes and its specificity with other areas such as rehabilitation), unclear units of analysis (i.e. differences between procedures, interventions, packages of care and care programs), lack of clearly stated evidence-based interventions in a mental health context; and lack of a well-defined taxonomical tree. An ontology approach to the definition of the different entities involved in the throughput of mental care, including their hierarchical relationships and conceptual map, may have contributed to the failure of previous systems together with the development of systems to classify mental health interventions separate from generic health interventions.

    Conclusions: The present review provides additional ground for the development of the ICHI knowledge-base and highlights the importance of taxonomical disambiguation and international comparability in the development and implementation of classifications of mental care interventions.

    Time invariance of three ultra-brief internet-related instruments: Smartphone Application-Based Addiction Scale (SABAS), Bergen Social Media Addiction Scale (BSMAS), and the nine-item Internet Gaming Disorder Scale- Short Form (IGDS-SF9) (Study Part B).2019In: Addictive Behaviours, ISSN 0306-4603, E-ISSN 1873-6327, article id S0306-4603(18)31357-1Article in journal (Refereed)
    Abstract [en]

    Given the many technological advances over the past two decades, a small minority of young people are at risk of problematic use or becoming addicted to these technologies (including activities on the internet and smartphones). Many brief psychometric scales have been developed to assess those at risk of problematic use or addiction including the six-item Smartphone Application-Based Addiction Scale [SABAS], the six-item Bergen Social Media Addiction Scale [BSMAS], and the nine-item Internet Gaming Disorder Scale-Short Form [IGDS-SF9]). However, to date, the reproducibility of these three scales has only been examined over a short period of time (e.g., two weeks), and it is unclear whether they are time invariant across a longer period (e.g., three months). Given the emergence of internet and smartphone addiction in Chinese population, the present study translated the three instruments into Chinese and recruited 640 university students (304 from Hong Kong [99 males] and 336 from Taiwan [167 males]) to complete the three scales twice (baseline and three months after baseline). Multigroup confirmatory factor analysis (MGCFA) was applied to examine the time invariance. The intraclass correlation coefficient (ICC) was used to assess the relative reliability, and the percentage of smallest real difference (SRD%) was utilized to explore the absolute reliability for the three scales. MGCFA showed that all three scales were time invariant across three months. ICC demonstrated that all the scales were satisfactory in reproducibility (0.82 to 0.94), and SRD% indicated that all the scales had acceptable measurement noise (23.8 to 29.4). In conclusion, the short, valid, reliable, and easy-to-use Chinese SABAS, BSMAS, and IGDS-SF9 show good properties across periods of three months.

    A comprehensive scoping review of ability and disability in ADHD using the International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY)2015In: European Child and Adolescent Psychiatry, ISSN 1018-8827, E-ISSN 1435-165X, Vol. 24, no 8, p. 859-872Article, review/survey (Refereed)
    Abstract [en]

    This is the first in a series of four empirical investigations to develop International Classification of Functioning, Disability and Health (ICF) Core Sets for Attention Deficit Hyperactivity Disorder (ADHD). The objective here was to use a comprehensive scoping review approach to identify the concepts of functional ability and disability used in the scientific ADHD literature and link these to the nomenclature of the ICF-CY. Systematic searches were conducted using Medline/PubMed, PsycINFO, ERIC and Cinahl, to extract the relevant concepts of functional ability and disability from the identified outcome studies of ADHD. These concepts were then linked to ICF-CY by two independent researchers using a standardized linking procedure. Data from identified studies were analysed until saturation of ICF-CY categories was reached. Eighty studies were included in the final analysis. Concepts contained in these studies were linked to 128 ICF-CY categories. Of these categories, 68 were considered to be particularly relevant to ADHD (i.e., identified in at least 5 % of the studies). Of these, 32 were related to Activities and participation, 31 were related to Body functions, and five were related to environmental factors. The five most frequently identified categories were school education (53 %), energy and drive functions (50 %), psychomotor functions (50 %), attention functions (49 %), and emotional functions (45 %). The broad variety of ICF-CY categories identified in this study underlines the necessity to consider ability and disability in ADHD across all dimensions of life, for which the ICF-CY provides a valuable and universally applicable framework. These results, in combination with three additional preparatory studies (expert survey, focus groups, clinical study), will provide a scientific basis to define the ICF Core Sets for ADHD for multi-purpose use in basic and applied research, and every day clinical practice.

    The Swedish National Board on Health and Welfare recommends that structured assessment instruments should be used in medical as well as in social treatment of substance misusers. These should be validated in a Swedish context. Instruments for diagnoses of dependence/abuse (DSM-IV) and dependence/harmful use (ICD-10) have been used in Sweden for many years, although not yet validated in Swedish. ADDIS, the Swedish version of the American SUDDS, is used in four Nordic countries and the most often used diagnostic instrument in Sweden. This article investigates the psychometric properties of ADDIS alcohol module, including discriminant and construct validity and internal consistency. The two main constructs in DSM - dependence and abuse - as well as the seven criteria for dependence and the four criteria for abuse are studied. Further, the value of each of the 44 specific items in ADDIS for capturing these criteria is studied.

    Two samples are explored: 1) a clinical sample (n = 349; incl. 129 women) and 2) a sample of 400 men convicted for driving while intoxicated. Mean age was the same (41 ys.). Using discriminant analyses on lifetime prevalence, the items correctly classify 94% of the cases in the two samples. Using one-factor principal component analysis to explore homogeneity of the combined samples, all 28 items on dependence and 15 of 18 items on abuse have loadings above 0,40 (R2 dependence = 0,46; abuse = 0,40). Separate analyses of the two samples, as well as on women, show similar results. Cronbach's alpha is excellent for dependence and satisfactory for abuse in all analyses. Analyses of specific criteria show satisfactory results on dependence and acceptable on abuse. Minor revisions are proposed to make ADDIS more user-friendly and to improve some specific items.

    In conclusion: ADDIS has acceptable to excellent discriminant and construct validity as well as internal consistency and captures the specific criteria of DSM-IV. It has the preconditions for sensitive assessment of alcohol use disorders in men and women.

    Psychometric properties of the Swedish version of the Childhood Trauma Questionnaire - Short Form (CTQ-SF)2009In: Nordic Journal of Psychiatry, ISSN 0803-9488, E-ISSN 1502-4725, Vol. 63, no 2, p. 160-170Article in journal (Refereed)
    Abstract [en]

    Childhood maltreatment is delicate to assess both in clinical work and in research. There is a need for assessment tools that can be easily administered in an ethical and non-intrusive way that meets requirements of conceptual validity for various types of maltreatment and is sensitive to levels of severity. This study explores the psychometric properties of the Swedish translation of one such tool—the Childhood Trauma Questionnaire—Short Form (CTQ-SF; Bernstein and Fink, 1998). The CTQ-SF was administered to seven samples (total n=659)—five clinical samples and two non-clinical student samples. The factor structure supports the construct validity of the global maltreatment scale, four of the five maltreatment subscales (emotional abuse, physical abuse, sexual abuse and emotional neglect) and the minimization/denial (MD) scale, but not the physical neglect (PN) subscale. All items are highly correlated with their respective subscale. The discriminant validity is satisfactory. Highly significant correlation with social desirability gives further support for the MD-scale and to the recommendation of how to apply it. Internal consistency of PN is acceptable and for all other scales satisfactory. Swedish norm groups tend to score lower than similar American norm groups on abuse scales but higher on the neglect scales. Percentiles for seven gender-specific norm groups are presented. The weaknesses of the PN-scale are discussed and new constructs are proposed. The Swedish version of the CTQ-SF has the same construct validity and internal consistency as the original, including less homogeneity of the PN scale.

    Mortality of treated alcoholics after eight years in relation to  short-term outcome1997In: Alcohol and Alcoholism, ISSN 0735-0414, E-ISSN 1464-3502, Vol. 32, no 5, p. 573-579Article in journal (Refereed)
    Abstract [en]

    This study concerns the relation between mortality and the short-term outcome of inpatient treatment for alcoholism. A total of 121 patients (87 men, 34 women) were included, of whom 89 were voluntary and 32 compulsorily committed. They had a mean age of 41±7 (SD) years and attended a 5-week programme at Runnagården, Örebro, Sweden. Most patients were socially unstable and severely alcohol-dependent. Ten months (mean) after discharge, 96% of the patients and their referring social workers were contacted with mail questionnaires. Of these patients, 13% had been totally abstinent and a further 42% improved but had had relapses. After a mean of 8.5±0.27 years, 27 patients (24%) had died. All abstainers survived, but non-abstainers had nine-fold higher mortality than expected. Non-abstinent improved women tended to survive longer than non-improved women, but among non-abstinent improved men no such tendency was found. In conclusion, a reduction in the frequency and quantity of abusive drinking was not enough to reduce the higher risk of death. Only abstinence seemed to be preventive.

    Factors affecting motivation to treatment in severely dependent alcoholics.2000In: Journal of Studies on Alcohol, ISSN 0096-882X, E-ISSN 1934-2683, Vol. 61, no 4, p. 548-560Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE:

    This article explores environmental, developmental and personality-related factors as predictors of motivation to treatment for alcoholism, using such concepts as: social situation on admission, treatment career, age, education and adventurous patterns of behavior.

    METHOD:

    The original population consists of 603 severely dependent alcoholic patients (76% men, 42% compulsorily committed) with a mean age of 40 years. In structural equation model estimation, 85% of the original cases were used (N = 511), made up of compulsorily as well as voluntarily admitted patients. A reduced model was tried on voluntary patients alone.

    RESULTS:

    In the main model, patterns of behavior and age were not related to the motivation to treatment, while treatment career had some negative impact. Social problems were related to less motivation to treatment. In turn, a worse social situation was related to more treatment experience. The reduced model on voluntary patients alone confirmed the main findings, although more previous treatment tended to be related to more motivation.

    CONCLUSIONS:

    Motivation was mostly related to a better social situation (i.e., having "more to lose"). A collapse in the social situation was more of an obstacle than a promoter of motivation. There was no support for statements that "maturing out" would result in more motivation, and findings were inconclusive concerning the impact on motivation of having had many previous treatment experiences. The pattern of behavior was not directly related to the level of motivation. Based on these findings, the relevance of social work for motivation to treatment is discussed.

    Personality factors and drug of choice in female addicts with psychiatric comorbidity2001In: Substance Use & Misuse, ISSN 1082-6084, E-ISSN 1532-2491, Vol. 37, no 1, p. 1-18Article in journal (Refereed)
    Abstract [en]

    Female addicts (N= 108) with a mean age of 37.2 were tested using the Temperament and Character Inventory (TCI) in 1996-97. In a representative sub-sample (N = 49) assessed with the Structured Clinical Interview. DSMIIIr (SCID), 82% manifested an axis-1-syndrome (lifetime), and 53% a personality disorder. Of the 108 addicts, 42 preferred alcohol, 14 heroin, 33 amphetamines, and 19 benzodiazepines. Maturity was low, but there were no differences in maturity between drug preference groups. Results indicated that those less mature were more "novelty-seeking" and "harm-avoidant", while those maturer tended to be more persistent. Less mature persons answered less consistently. They agreed more with different items and their answers were more rare when compared to the general population. Heroin addicts were less sentimental and helpful and more aware of their own resources. Benzodiazepine and amphetamine addicts were more self-transcendent and self-forgetful. Among the relatively more mature, benzodiazepine addicts scored higher than heroin and alcohol addicts on "true" and rare answers. In conclusion, maturity and the drug of choice among female addicts were related to different TCI scales.

    Predictors of gambling problems among male adolescents.2003In: International Journal of Social Welfare, ISSN 1369-6866, E-ISSN 1468-2397, Vol. 12, no 3, p. 182-192Article in journal (Refereed)
    Abstract [en]

    The study concerns prediction of gambling problems in 178 male adolescents (aged 16 and 18 years) who completed a questionnaire, which included the South Oaks Gambling Screen (SOGS), a version of the Temperament and Character Inventory and a number of questions concerning social background, emotional and life-style factors. About 27% of the boys gamble at least weekly. As many as 16% qualify as probable pathological gamblers according to the SOGS. Another 7% are at risk. None of the social background factors are related to severity of gambling problems. The only significant family factor is parental substance misuse. The optimal multivariate model predicts about 30% of the variance in gambling problems. The strongest factor is frequency of alcohol drinking. Several factors indicate a personality with problems in relations to others. Another factor indicates a dreamy personality. Unexpectedly, impulsiveness is not related to gambling. In conclusion, problem gambling among male adolescents is related to life-style and personality, especially in relation to others, but not to usual social background factors. Gamblers are asocial rather than impulsive. The nature of this finding should be further explored, since an asocial personality may point at genetics as well as to early social influences, as may the finding on the relation between gambling and parental drinking.

    Typically developed adults and adults with autism spectrum disorder classification using centre of pressure measurements2016In: 2016 IEEE International Conference on Acoustics, Speech, and Signal Processing: proceedings, Institute of Electrical and Electronics Engineers (IEEE), 2016, Vol. 41, p. 844-848Conference paper (Refereed)
    Abstract [en]

    Autism spectrum disorders (ASD) are neurodevelopmental disorders which affect a persons ability to interact with the world around him/her. Emerging studies have shown abnormal postural control in people with ASD. The aim of this study was to enable the classification of adults with ASD and typically developed (TD) adults based on force plate measurements of centre of pressure. Nineteen typical adults and eleven adults diagnosed with ASD primarily high functioning autism or Asperger's syndrome participated in this study. A correlation-based feature selection algorithm was used to evaluate the quality of the attributes and the results have achieved up to 0.976 classification accuracy.

    The severity and nature of motor impairment in Asperger's syndrome: A comparison with Specific Developmental Disorder of Motor Function2002In: Journal of Child Psychology and Psychiatry and Allied Disciplines, ISSN 0021-9630, E-ISSN 1469-7610, Vol. 43, no 5, p. 655-668Article in journal (Refereed)
    Abstract [en]

    Background:

    The aims of this study were to measure objectively the extent and severity of motor impairment in children with Asperger's syndrome and to determine whether the motor difficulties experienced by such children differed in any way from those classified as having a Specific Developmental Disorder of Motor Function (SDD-MF). Criteria derived from ICD 10-R were used to identify 11 children with Asperger's syndrome and a matched group of 9 children with a Specific Developmental Disorder of Motor Function. Children in both groups were required to have a verbal IQ of 80 or greater on the WISC IIIR.

    Method:

    The Autism Diagnostic Interview (Revised; Lord, Rutter, & LeCouteur, 1994) was used to identify features of AS in the first group and to exclude them in the latter. The Movement Assessment Battery for Children (Henderson & Sugden, 1992) provided a standardised test of motor impairment. A Gesture Test based on that by Cermak, Coster, and Drake (1980) was used to assess the child's ability to mime the use of familiar tools and to imitate meaningless sequences of movements.

    Results:

    All the children with Asperger's syndrome turned out to meet our criterion for a diagnosis of motor impairment, five of the six most severely motor impaired children in the whole study being from this group. Performance of the Asperger group was also slightly poorer on the Gesture Test. The profile of performance on each test was examined in detail but no evidence of group differences in the pattern of impairment was found.

    Conclusions:

    This study is consistent with others suggesting a high prevalence of clumsiness in Asperger's syndrome. Our findings also attest to the widespread prevalence of motor impairment in developmental disorders and the problems such co-morbidity poses for attempts to posit discrete and functionally coherent impairments underlying distinct syndromes.

    A learning health system for people with severe mental illness: a promise for continuous learning, patient coproduction and more effective care2019In: Digital Psychiatry, ISSN 2575-517X, Vol. 2, no 1, p. 8-13Article in journal (Refereed)
    Abstract [en]

    A Learning Health System (LHS) promotes the patient being at the very center of his or her care. Patient coproduction of care in an LHS is enabled by a focus on improving outcomes through the use of tools and visualizations that use the harnessed knowledge obtained from every previous treatment of similar patients. Interest in the concept of LHS is growing, and there are promising results in real-world applications. Almost no research has focused on LHSs for severe mental illness (LHS4SMI). By using a user-centered system design approach, a persona and use-case scenarios were created to illustrate how schizophrenia care could be co-produced in an LHS compared to standard care in a non-LHS. The illustration highlight increased participation through decisions informed by all treatments for all similar patients through the use of user interfaces that support continuous evaluation, increased understanding, compensation for cognitive impairment and participation of next of kin in the care process. We propose that an LHS4SMIs like schizophrenia has enormous potential in enabling continuous learning, patient coproduction, and more effective care.

    Hyperactivity precedes conduct problems in preschool children: a longitudinal study2018In: BJPsych Open, E-ISSN 2056-4724, Vol. 4, no 4, p. 186-191Article in journal (Refereed)
    Abstract [en]

    Background

    Externalising problems are among the most common symptoms of mental health problems in preschool children.

    Aims

    To investigate the development of externalising problems in preschool children over time, and the way in which conduct problems are linked to hyperactivity problems.

    Method

    In this longitudinal study, 195 preschool children were included. Latent growth modelling of conduct problems was carried out, with gender and hyperactivity at year 1 as time-invariant predictors.

    Results

    Hyperactivity was a significant predictor for the intercept and slope of conduct problems. Children with more hyperactivity at year 1 had more conduct problems and a slower reduction in conduct problems. Gender was a significant predictor for the slope of conduct problems.

    Conclusions

    Children with more initial hyperactivity have less of a reduction in conduct problems over time. It is important to consider the role of hyperactivity in studies of the development of conduct problems.

    Emotional and behavioural problems in Swedish preschool children rated by preschool teachers with the Strengths and Difficulties Questionnaire (SDQ)2017In: BMC Pediatrics, ISSN 1471-2431, E-ISSN 1471-2431, Vol. 17, no 1, article id 110Article in journal (Refereed)
    Abstract [en]

    Background: There is a high risk that young children who show early signs of mental health problems develop symptoms in the same or overlapping areas some years later. The Strengths and Difficulties Questionnaire (SDQ) is widely used to screen externalizing and internalizing problems early in life. In Sweden 80-90% of all children aged 1-5 years go to preschool and preschool is thus an appropriate context for finding early signs of mental health problems among children.

    Methods: This study is part of a longitudinal project too investigate the frequency of emotional and behavioural problems for children between 1 and 5 years of age in Sweden. The SDQ including the impairment supplement questions were rated by preschool teachers too establish Swedish norms for SDQ in preschool children.

    Results: The sample involved 815 children with a mean age of 42 months (SD = 16, range 13-71 months). 195 children were followed longitudinally for three years. There were significant differences between boys and girls on all subscales except for the Emotional subscale. The prevalence of behavioural problems was similar to other that in European countries, except for Prosocial behaviour, which was rated lower, and Conduct problems, rated higher. Swedish children were estimated to have more problems in the preschool setting, scored by preschool teachers. The development of behaviour over time differed for the different subscales of SDQ.

    Conclusions: The teacher version of the SDQ, for 2-4 year-olds, can be used as a screening instrument to identify early signs of emotional distress/behavioural problems in young children. Preschool teachers seem to be able to identify children with problematic behaviour with the use of SDQ at an early age. The development of behaviour over time differs for the different subscales of SDQ. The Swedish norms for SDQ are to a large extent, similar to findings from other European countries.

    Exercise and internet-based cognitive-behavioural therapy for depression: Multicentre randomized controlled trial with 12-month follow-up2016In: British Journal of Psychiatry, ISSN 0007-1250, E-ISSN 1472-1465, Vol. 209, no 5, p. 414-420Article in journal (Refereed)
    Abstract [en]

    Background

    Evidence-based treatment of depression continues to grow, but successful treatment and maintenance of treatment response remains limited.

    Aims

    To compare the effectiveness of exercise, internet-based cognitive-behavioural therapy (ICBT) and usual care for depression.

    Method

    A multicentre, three-group parallel, randomised controlled trial was conducted with assessment at 3 months (posttreatment) and 12 months (primary end-point). Outcome assessors were masked to group allocation. Computer-generated allocation was performed externally in blocks of 36 and the ratio of participants per group was 1:1:1. In total, 945 adults with mild to moderate depression aged 18-71 years were recruited from primary healthcare centres located throughout Sweden. Participants were randomly assigned to one of three 12-week interventions: supervised group exercise, clinician-supported ICBT or usual care by a physician. The primary outcome was depression severity assessed by the Montgomery-Åsberg Depression Rating Scale (MADRS).

    Results

    The response rate at 12-month follow-up was 84%. Depression severity reduced significantly in all three treatment groups in a quadratic trend over time. Mean differences in MADRS score at 12 months were 12.1 (ICBT), 11.4 (exercise) and 9.7 (usual care). At the primary end-point the group x time interaction was significant for both exercise and ICBT. Effect sizes for both interventions were small to moderate.

    Conclusions

    The long-term treatment effects reported here suggest that prescribed exercise and clinician-supported ICBT should be considered for the treatment of mild to moderate depression in adults.

    Physical exercise and internet-based cognitive-behavioural therapy in the treatment of depression: Randomised controlled trial2015In: British Journal of Psychiatry, ISSN 0007-1250, E-ISSN 1472-1465, Vol. 207, no 3, p. 227-234Article in journal (Refereed)
    Abstract [en]

    Background

    Depression is common and tends to be recurrent. Alternative treatments are needed that are non-stigmatising, accessible and can be prescribed by general medical practitioners.

    Aims

    To compare the effectiveness of three interventions for depression: physical exercise, internet-based cognitive-behavioural therapy (ICBT) and treatment as usual (TAU). A secondary aim was to assess changes in self-rated work capacity.

    Method

    A total of 946 patients diagnosed with mild to moderate depression were recruited through primary healthcare centres across Sweden and randomly assigned to one of three 12-week interventions (trail registry: KCTR study ID: KT20110063). Patients were reassessed at 3 months (response rate 78%).

    Results

    Patients in the exercise and ICBT groups reported larger improvements in depressive symptoms compared with TAU. Work capacity improved over time in all three groups (no significant differences).

    Conclusions

    Exercise and ICBT were more effective than TAU by a general medical practitioner, and both represent promising non-stigmatising treatment alternatives for patients with mild to moderate depression.

    Passive and mentally-active sedentary behaviors and incident major depressive disorder: A 13-year cohort study2018In: Journal of Affective Disorders, ISSN 0165-0327, E-ISSN 1573-2517, Vol. 241, p. 579-585Article in journal (Refereed)
    Abstract [en]

    Background: Regular physical activity reduces the risk of depression onset and is an effective treatment for mood disorders. Recent studies have reported that sedentary behavior (SB) increases the risk of depression in adults, but relationships of different types of SBs with depression have not been examined systematically. We explored longitudinal relationships of passive (e.g. watching TV) and mentally-active (e.g. office-work) SBs with incident major depressive disorder (MDD).

    Methods: Self-report questionnaires were completed by 40,569 Swedish adults in 1997; responses were linked to clinician-diagnosed MDD obtained from medical registers until 2010. Relationships between passive, mentally-active and total SBs with incident MDD were explored using survival analysis with Cox proportional hazards regression. Models controlled for leisure time moderate-vigorous physical activity and occupational physical activity. Moderating effects of gender were examined.

    Results: In fully-adjusted models, including only non-depressed adults at baseline, those reporting ≥ 3 h of mentally-active SBs on a typical day (versus < 3 h) had significant lower hazards of incident MDD at follow-up (HR = 0.74, 95% CI = 0.58–0.94, p = 0.018). There was a non-significant positive relationship of passive SBs with incident MDD (HR = 1.20, 95% CI = 0.96–1.52, p = 0.106). The association between total SBs (passive and mentally-active combined) was not significant (HR = 0.91, 95% CI = 0.75–1.10, p = 0.36). Gender did not moderate these associations.

    Limitations: Physical activity and SBs were self-reported.

    Conclusion: Mentally-active SBs may have beneficial effects on adults’ mental well-being. These effects are largely independent of habitual physical activity levels.

    Association of vitamin B12, folate, and sulfur amino acids with brain magnetic resonance imaging measures in older adults: A longitudinal population-based study2016In: JAMA psychiatry, ISSN 2168-6238, E-ISSN 2168-622X, Vol. 73, no 6, p. 606-613Article in journal (Refereed)
    Abstract [en]

    Importance 

    Vitamin B12, folate, and sulfur amino acids may be modifiable risk factors for structural brain changes that precede clinical dementia.

    Objective 

    To investigate the association of circulating levels of vitamin B12, red blood cell folate, and sulfur amino acids with the rate of total brain volume loss and the change in white matter hyperintensity volume as measured by fluid-attenuated inversion recovery in older adults.

    Design, Setting, and Participants 

    The magnetic resonance imaging subsample of the Swedish National Study on Aging and Care in Kungsholmen, a population-based longitudinal study in Stockholm, Sweden, was conducted in 501 participants aged 60 years or older who were free of dementia at baseline. A total of 299 participants underwent repeated structural brain magnetic resonance imaging scans from September 17, 2001, to December 17, 2009.

    Main Outcomes and Measures 

    The rate of brain tissue volume loss and the progression of total white matter hyperintensity volume.

    Results 

    In the multi-adjusted linear mixed models, among 501 participants (300 women [59.9%]; mean [SD] age, 70.9 [9.1] years), higher baseline vitamin B12 and holotranscobalamin levels were associated with a decreased rate of total brain volume loss during the study period: for each increase of 1 SD, β (SE) was 0.048 (0.013) for vitamin B12 (P < .001) and 0.040 (0.013) for holotranscobalamin (P  = .002). Increased total homocysteine levels were associated with faster rates of total brain volume loss in the whole sample (β [SE] per 1-SD increase, –0.035 [0.015]; P = .02) and with the progression of white matter hyperintensity among participants with systolic blood pressure greater than 140 mm Hg (β [SE] per 1-SD increase, 0.000019 [0.00001]; P = .047). No longitudinal associations were found for red blood cell folate and other sulfur amino acids.

    Conclusions and Relevance 

    This study suggests that both vitamin B12 and total homocysteine concentrations may be related to accelerated aging of the brain. Randomized clinical trials are needed to determine the importance of vitamin B12 supplementation on slowing brain aging in older adults.

    Compulsory Commitment to Care of Substance Misusers: A Worldwide Comparative Analysis of the Legislation2010In: The Open Addiction Journal, ISSN 1874-9410, Vol. 3, no 1, p. 117-130Article in journal (Refereed)
    Abstract [en]

    This study explores the worldwide use of compulsory commitment to care (CCC) at the end of the 20th century and evaluates the implementation of WHO recommendations since the 1960s. Based on three WHO reports, the legislation of 90 countries and territories are analyzed, and types as well as predictors of such legislation are analyzed in multivariate models from country characteristics. Laws on CCC for alcohol and drug misusers are common all over the world; more than 80 percent of the countries and territories studied have such laws. The majority use civil commitment – acute or rehabilitative – in accordance with welfare logic, while a large minority still uses commitment under criminal law, based on a moral logic. Civil CCC is positively related to strong economies or having been part of the Soviet legal system. CCC under criminal law is negatively related to the same factors.

    Compulsory commitment to care of substance misusers: international trends during 25 years2012In: European Addiction Research, ISSN 1022-6877, E-ISSN 1421-9891, Vol. 18, no 6, p. 302-321Article in journal (Refereed)
    Abstract [en]

    Purpose: The study explores international trends in law on compulsory commitment to care of substance misusers (CCC), and two subtypes – civil CCC and CCC within criminal justice legislation – as well as maximum length and amount of applications of such care. Method: The time period covers more than 25 years, and a total of 104 countries and territories. The study is based on available data in three times of observation (1986, 1999 and 2009). Applications of CCC in number of cases are studied on European level for the years 2002–2006. Trends are analyzed using nonparametric tests and general linear models for repeated measures. Findings are discussed from contextual analysis. Result: There is a trend towards decrease in the number of countries worldwide having civil CCC legislation after the millennium, while CCC under criminal law has increased since the mid-1980s, resulting in some total net decrease. The shift results in longer mean duration of CCC and an increase in the number of cases sentenced. Conclusion: There is a risk that the shift from civil CCC to penal CCC implies more focus on young out-acting males in compulsory treatment and that the societal responsibility for more vulnerable persons might be neglected.

    Measurement invariance across young adults from Hong Kong and Taiwan among three internet-related addiction scales: Bergen Social Media Addiction Scale (BSMAS), Smartphone Application-Based Addiction Scale (SABAS), and Internet Gaming Disorder Scale-Short Form (IGDS-SF9) (Study Part A).2019In: Addictive Behaviours, ISSN 0306-4603, E-ISSN 1873-6327, article id S0306-4603(18)31156-0Article in journal (Refereed)
    Abstract [en]

    Internet addiction has been found to be prevalent worldwide, including Asian countries, and related to several negative outcomes and other behavioral addictions. The Bergen Social Media Addiction Scale (BSMAS), Smartphone Application-Based Addiction Scale (SABAS), and nine-item Internet Gaming Disorder Scale-Short Form (IGDS-SF9) have been extensively used to assess internet-related addictions. However, the three aforementioned instruments have rarely been used in Asian countries. The aim of the present study was to investigate whether the BSMAS, SABAS, and IGDS-SF9 were appropriate for use in heterogeneous subsamples from Hong Kong and Taiwan. University students from Hong Kong (n = 306) and Taiwan (n = 336) were recruited via an online survey. Multigroup confirmatory factor analysis (MGCFA) was used to assess measurement invariance of the BSMAS, SABAS, and IGDS-SF9 across the two subcultures. The original unidimensional structures of BSMAS, SABAS and IGDS-SF9 were confirmed through confirmatory factorial analysis in both subcultures. The MGCFA results showed that the unidimensional structures of the BSMAS and IGDS-SF9 were invariant across the two Chinese cultural areas (Hong Kong and Taiwan). However, the measurement invariance of the SABAS was established after some model modifications. In conclusion, the present study found that the Chinese BSMAS, SABAS, and IGDS-SF9 were all adequate instruments to validly assess internet-related addictions among university students. The three brief instruments used for assessing addictions to social media, smartphone applications, and online gaming are valid and psychometrically robust across two Chinese subcultures and can be used by healthcare professionals in these regions.

    Structured risk assessment instruments: A systematic review of implementation determinants2016In: Psychiatry, Psychology and Law, ISSN 1321-8719, E-ISSN 1934-1687, Vol. 23, no 4, p. 602-628Article in journal (Refereed)
    Abstract [en]

    Research-based structured risk assessment instruments (SRAIs) can improve violence risk assessment and clinical judgements in mental health and correctional services. Practical challenges of implementing SRAIs have led to calls for more research to understand the determinants influencing this process. Studies describing determinants for SRAI implementation in psychiatric, correctional, or community in-patient settings were systematically reviewed. Findings were analysed according to the Consolidated Framework for Implementation Research. A total of 11 studies were included. Four types of main implementation determinants were found: characteristics of the SRAI; users of the SRAI; inner setting; and process. Findings underscore the importance of applying a multifactorial approach to the implementation of SRAIs to address many different barriers and facilitators. More stringent research is needed to obtain more solid evidence of factors that impede or enable SRAI implementation, especially regarding patient perspectives and outer setting determinants. Constructing shared concepts of determinants across research fields could further aid information transferences.

    Psychometric validation of the Persian bergen social media addiction scale using classic test theory and Rasch models2017In: Journal of Behavioral Addictions, ISSN 2062-5871, E-ISSN 2063-5303, Vol. 6, no 4, p. 620-629Article in journal (Refereed)
    Abstract [en]

    Background and aims: The Bergen Social Media Addiction Scale (BSMAS), a six-item self-report scale that is a brief and effective psychometric instrument for assessing at-risk social media addiction on the Internet. However, its psychometric properties in Persian have never been examined and no studies have applied Rasch analysis for the psychometric testing. This study aimed to verify the construct validity of the Persian BSMAS using confirmatory factor analysis (CFA) and Rasch models among 2,676 Iranian adolescents.

    Methods: In addition to construct validity, measurement invariance in CFA and differential item functioning (DIF) in Rasch analysis across gender were tested for in the Persian BSMAS.

    Results: Both CFA [comparative fit index (CFI) = 0.993; Tucker-Lewis index (TLI) = 0.989; root mean square error of approximation (RMSEA) = 0.057; standardized root mean square residual (SRMR) = 0.039] and Rasch (infit MnSq = 0.88-1.28; outfit MnSq = 0.86-1.22) confirmed the unidimensionality of the BSMAS. Moreover, measurement invariance was supported in multigroup CFA including metric invariance (ΔCFI = .0.001; ΔSRMR = 0.003; ΔRMSEA = .0.005) and scalar invariance (ΔCFI = .0.002; ΔSRMR = 0.005; ΔRMSEA = 0.001) across gender. No item displayed DIF (DIF contrast = .0.48 to 0.24) in Rasch across gender.

    Conclusions: Given the Persian BSMAS was unidimensional, it is concluded that the instrument can be used to assess how an adolescent is addicted to social media on the Internet. Moreover, users of the instrument may comfortably compare the sum scores of the BSMAS across gender.

    Psychometric evaluation of the Persian Internet Disorder Scale among adolescents.2018In: Journal of Behavioral Addictions, ISSN 2062-5871, E-ISSN 2063-5303, Vol. 7, no 3, p. 665-675Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND AIMS: Given the growing epidemiological research interest concerning Internet addiction, brief instruments with a robust theoretical basis are warranted. The Internet Disorder Scale (IDS-15) is one such instrument that can be used to quickly assess the Internet addiction in an individual. However, only two language versions of the IDS-15 have been developed. This study translated the IDS-15 into Persian and examined its psychometric properties using comprehensive psychometric testing.

    METHODS: After ensuring the linguistic validity of the Persian IDS-15, 1,272 adolescents (mean age = 15.53 years; 728 males) completed the IDS-15, Depression Anxiety Stress Scale (DASS), Internet Gaming Disorder Scale - Short Form (IGDS9-SF), and the Bergen Social Media Addiction Scale (BSMAS). Confirmatory factor analysis (CFA), Rasch models, regression analysis, and latent profile analysis (LPA) were carried out to test the psychometric properties of the Persian IDS-15.

    RESULTS: Both CFA and Rasch supported the construct validity of the Persian IDS-15. Multigroup analysis in CFA and differential item functioning in Rasch indicated that male and female adolescents interpreted the IDS-15 items similarly. Regression analysis showed that the IDS-15 correlated with IGDS9-SF and BSMAS (ΔR2 = .12 and .36, respectively) is stronger than the DASS (ΔR2 = .03-.05). LPA based on IDS-15 suggests three subgroups for the sample. Significant differences in depression, anxiety, IGDS9-SF, and BSMAS were found among the three LPA subgroups.

    CONCLUSION: The Persian IDS-15 has robust psychometric properties as evidenced by both classical test theory and Rasch analysis.

    Childhood trauma in adults with social anxiety disorder and panic disorder: A cross-national study2010In: African Journal of Psychiatry, ISSN 1994-8220, Vol. 13, no 5, p. 376-381Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES:

    The influence of childhood trauma as a specific environmental factor on the development of adult psychopathology is far from being elucidated. As part of a collaborative project between research groups from South Africa (SA) and Sweden focusing on genetic and environmental factors contributing to anxiety disorders, this study specifically investigated rates of childhood trauma in South African and Swedish patients respectively, and whether, in the sample as a whole, different traumatic experiences in childhood are predictive of social anxiety (SAD) or panic disorder (PD) in adulthood.

    METHOD:

    Participants with SAD or PD (85 from SA, 135 from Sweden) completed the Childhood Trauma Questionnaire (CTQ). Logistic regression was performed with data from the two countries separately, and from the sample as a whole, with primary diagnoses as dependent variables, gender, age, and country as covariates, and the CTQ subscale totals as independent variables. The study also investigated the internal consistency (Cronbach alpha) of the CTQ subscales.

    RESULTS:

    SA patients showed higher levels of childhood trauma than Swedish patients. When data from both countries were combined, SAD patients reported higher rates of childhood emotional abuse compared to those with PD. Moreover, emotional abuse in childhood was found to play a predictive role in SAD/PD in adulthood in the Swedish and the combined samples, and the same trend was found in the SA sample. The psychometric qualities of the CTQ subscales were adequate, with the exception of the physical neglect subscale.

    CONCLUSION:

    Our findings suggest that anxiety disorder patients may differ across countries in terms of childhood trauma. Certain forms of childhood abuse may contribute specific vulnerability to different types of psychopathology. Longitudinal studies should focus on the potential sequential development of SAD/PD among individuals with childhood emotional abuse.

    Childhood Abuse and Neglect in Severely Dependent Female Addicts: Homogeneity and reliability of a Swedish Version of the Childhood Trauma Questionnaire2002In: International Journal of Social Welfare, ISSN 1369-6866, E-ISSN 1468-2397, Vol. 11, no 3, p. 219-227Article in journal (Refereed)
    Abstract [en]

    This study explores the psychometric characteristics of childhood experiences (‘Barndomsupplevelser’), using a Swedish translation of the 53–item version of the Childhood Trauma Questionnaire (CTQ). Fifty–five female addicts, treated in a compulsory–care setting, completed the questionnaire. Homogeneity and reliability were studied using principal component analyses (PCA) and Cronbach’s alpha. The test was submitted to content analysis. Nearly all (94.5%) had experienced childhood abuse or neglect. The internal consistency is high. The 4–factor solution corresponded to the subscales of emotional and physical abuse (combined), of sexual abuse and of emotional neglect, while the items in the physical neglect subscale were distributed to several factors. In the 5–factor solution, this subscale was divided into two factors. Content analyses of these factors point to other meanings than physical neglect. The CTQ (Swedish translation) was found to have high consistency and homogeneity in four of the five subscales (emotional, physical and sexual abuse, and emotional neglect), while the subscale on physical neglect may need revision. The new 28–item brief version seems to be an improvement, with regard to these problems.

    Abstract [en]

    Childhood maltreatment has diverse, lifelong impact on morbidity and mortality. The Childhood Trauma Questionnaire (CTQ) is one of the most commonly used scales to assess and quantify these experiences and their impact. Curiously, despite very widespread use of the CTQ, scores on its Minimization-Denial (MD) subscale-originally designed to assess a positive response bias-are rarely reported. Hence, little is known about this measure. If response biases are either common or consequential, current practices of ignoring the MD scale deserve revision. Therewith, we designed a study to investigate 3 aspects of minimization, as defined by the CTQ's MD scale: 1) its prevalence; 2) its latent structure; and finally 3) whether minimization moderates the CTQ's discriminative validity in terms of distinguishing between psychiatric patients and community volunteers. Archival, item-level CTQ data from 24 multinational samples were combined for a total of 19,652 participants. Analyses indicated: 1) minimization is common; 2) minimization functions as a continuous construct; and 3) high MD scores attenuate the ability of the CTQ to distinguish between psychiatric patients and community volunteers. Overall, results suggest that a minimizing response bias-as detected by the MD subscale-has a small but significant moderating effect on the CTQ's discriminative validity. Results also may suggest that some prior analyses of maltreatment rates or the effects of early maltreatment that have used the CTQ may have underestimated its incidence and impact. We caution researchers and clinicians about the widespread practice of using the CTQ without the MD or collecting MD data but failing to assess and control for its effects on outcomes or dependent variables. © 2016 MacDonald et al.
