An HIV researcher explored the factors that influenced condom use with a new partner (relationship less than 1 month old). The outcome measure was whether a condom was used (use: condom used = 1, not used = 0). The predictor variables were mainly scales from the Condom Attitude Scale (Sacco et al., 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 (experience); 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 (self_control); the degree to which the person perceives a risk from unprotected sex (risk_perception). Previous research has shown that gender, relationship safety andperceived risk predict condom use (Sacco et al., 1991). Verify these previous findings and test whether self-control, previous usage and sexual experience predict condom use (condom.sav).
