Background: The population of women in homelessness in Europe is increasing and women in homelessness experience multiple healthcare needs. However, there is insufficient understanding about how perceptions of caring behaviours compare between women in homelessness as patients and nurses in their clinical practice.

Aim: This study aimed to investigate perceptions of caring behaviours among women in homelessness, Registered Nurses and nursing students. Methods: A cross-sectional design was used with convenience sampling to recruit groups of women in homelessness (n = 37), Registered Nurses (n = 92) and nursing students (n = 142) in Stockholm, Sweden. Between August 2019 and December 2020, data were collected through face-to-face interviews or online, using the Caring Behaviours Inventory-24 instrument. Data were analysed using descriptive statistics and group-comparing hypothesis tests.

Results: Overall, women in homelessness’ perceptions of caring behaviours were significantly lower than nursing students (p < 0.001), who in turn scored significantly lower than Registered Nurses (p < 0.001). The Knowledge and Skill domain had the highest score, and the Connectedness domain had the lowest score in all three groups. The ranking of the individual items according to score varied between the groups. However, all three groups had the highest score for the Knowing how to give shots, IVs, etc., item and the lowest score for the Helping the patient to grow item.

Conclusion: Healthcare providers and nurse educators should consider incongruences and congruences in caring behaviours to better prepare Registered Nurses and nursing students to contribute to increased health equity, and more targeted clinical practice for women in homelessness.
