Diary study of substance use and unsafe sex among adolescents with substance use disorders

As in other event-level studies, substance use was not related to condom use in our study. Novel results in our study showed that the salience of preventing negative outcomes is a significant predictor of condom use even in the context of event-level substance use and partner type. These results suggest that prevention efforts for substance-using youth should not focus on preventing substance use as a way to prevent unsafe sex, but should emphasize the potential costs of unsafe sex even with known partners.
