Effects of a drinking event on behavioral skills and condom attitudes in men: implications for HIV risk from a controlled experiment.

This study experimentally tested the effects of a drinking event on HIV-related behavioral skills and condom attitudes. Sixty unmarried, heterosexual men were assigned to 1 of 3 conditions (sober, placebo, or alcohol). Participants who consumed alcohol demonstrated lower skill to negotiate for condom use relative to sober controls. More negative condom attitudes were expressed by participants with stronger sex-related alcohol expectancies, especially when these expectancies were triggered by subjective intoxication. Hierarchical regression analyses revealed that the experimental factors accounted for variance in behavioral skills and condom attitudes beyond that explained by known predictors of sexual risk.
