A dyadic approach to understanding safer sex behavior in intimate heterosexual relationships

Abstract

This study applied a dyadic approach to condom-use research. Partners from 124 heterosexual couples independently completed a questionnaire assessing condom-related attitudes, subjective norms, perceived behavioral control, and intentions to use condoms. Results demonstrate the superiority of a dyadic approach to understanding couples’ condom-use intentions and behavior over traditional, individual-level approaches. The addition of partner effects to the model, via the actor–partner interdependence model, resulted in an increase in the variance accounted for in condom-use intentions and this dyadic model showed better fit compared to the individual-level model. The results suggest that consideration of relationship partners plays an important role in the prediction of safer sex intentions.
