Multi-partnered heterosexuals' condom use for vaginal sex with their main partner as a function of attitude, subjective norm, partner norm, perceived behavioural control and weighted control beliefs

This paper examines the extent to which an integrated theoretical behavioural prediction model can explain the intentions of 215 male and 181 female multi-partnered heterosexuals (MPHs) to always use condoms for vaginal sex with their regular partners. For female MPHs, all five of the immediate psychosocial determinants of intention (i.e. attitude, subjective norm, partner norm, perceived behavioural control and the mean of weighted control beliefs) were significant independent predictors of condom use intentions R = 0.81). For male MPHs, only attitude (beta = 0.45) and partner norm (beta = 0.41) contributed independently to the explanation of these intentions R = 0.77). Behavioural, normative and control beliefs underlying the MPHs intentions to always use condoms for vaginal sex with their regular partners are identified as critical intervention targets.
