Factors influencing MSMs' intentions to always use condoms for vaginal, anal and oral sex with their regular partners

A revised behavioural prediction model integrating components of several psychosocial theories was used to predict men who have sex with mens' (MSM) (N = 139) intentions to always use condoms with their regular partner for anal, oral and vaginal sex. The behavioural model successfully predicted MSMs' condom use intentions for all three behaviours (R = 0.70, R = 0.75 and R = 0.78 for vaginal, anal and oral sex, respectively). Consistent with expectations, the relative importance of the underlying theoretical determinants differed for the three behaviours in question. For condom use for vaginal sex, the partner norm (beta = 0.54) and the mean of the weighted control beliefs (beta = 0.28) were most important. For condom use for anal sex, the partner norm (beta = 0.50), attitude (beta = 0.28) and perceived behavioural control (beta = 0.17) were most important. With respect to oral sex, attitude (beta = 0.51) and partner norm (beta = 0.38) were most important in independently influencing MSMs' intentions to always use condoms.
