The effects of cultural factors on condom use were assessed in a random digit-dialing household survey of 1,600 unmarried Latino adults in 10 states with large Latino populations. Measures of traditional gender-role beliefs, sexual coercion, sexual comfort, and self-efficacy in using condoms were developed specifically for this population. A multisample structural equation model analysis included 594 men who reported one or more heterosexual partners in the 12 months before interview. As predicted, men with more traditional gender-role beliefs reported more sexual coercion and less sexual comfort. Men reporting more sexual coercion and less sexual comfort had lower condom self-efficacy. Men with more condom self-efficacy and stronger condom social norms reported more condom use.
