Background and aim: Couples’ communication concerning sexual issues is influenced by various individual and social factors. The present study investigated the socio-demographic predictors of dyadic sexual communication among married women of reproductive age.

Methods: A cross-sectional survey study was conducted from May to October 2019 in comprehensive health centers of Qazvin City, Iran. The participants comprised 400 married women with mean age of 35.66 years recruited via a two-stage sampling method. The Dyadic Sexual Communication Scale (DSCS) and a socio-demographic questionnaire were used for data collection. Univariable and multivariable linear regression models with a significance level of 0.05 were used for statistical analysis.

Results: The mean score of sexual communication was 59.19 out of 78 (SD = 12.63). Based on multivariable linear regression model, life satisfaction (β = 0.34 high vs. moderate), frequency of sexual intercourse (β = 0.20), moderate vs. poor economic status (β = 0.12), and using contraception (β = −0.09) were predictors of good dyadic sexual communication. These variables explained 32% of the variance concerning dyadic sexual communication among married women of reproductive age.

Conclusion: Life satisfaction, frequency of sexual intercourse, moderate economic status, and using contraception were predictors of good dyadic sexual communication.
