=+1, not used = 0). The predictor variables were mainly scales from the Condom Attitude Scale (CAS) by Sacco, Levine, Reed, & Thompson

(1991): Gender; the degree to which the person views their relationship as ‘safe’ from sexually transmitted disease (Safety); the degree to which previous experience influences attitudes towards condom use (Sexexp);

whether or not the couple used a condom in their previous encounter

(Previous: 1 = condom used, 0 = not used, 2 = no previous encounter with this partner); the degree of self-control that a person has when it comes to condom use (Selfcon); the degree to which the person perceives a risk from unprotected sex (Perceive). Previous research (Sacco, Rickman, Thompson, Levine, & Reed, 1993) has shown that gender, relationship safety and perceived risk predict condom use. Verify these previous findings and test whether self-control, previous usage and sexual experience predict condom use (Condom.sav).
