Sexually-related expectancies for alcohol use and marijuana use among juvenile detainees

This study is focused on sexually-related expectancies for substance use among juvenile detainees. Over a 6 month period, 272 juveniles recruited from a short-term detention facility completed measures assessing sexually-related expectancies in relation to alcohol use and marijuana use as well as measures assessing their actual use of these substances. Repeated measures analyses of sexual risk expectancy measures indicated that the sample as a whole, and older respondents in particular, expected more sexual risk in relation to using alcohol than in relation to using marijuana. Repeated measures analyses of sexual enhancement expectancy measures indicated that African-American and younger respondents expected more sexual enhancement from using marijuana than from using alcohol. Logistic regression analyses indicated that expectancies for sexual enhancement from alcohol use, and expectancies for sexual enhancement from marijuana use, were respectively associated with the use of these substances in a recent sexual incident. Limitations of the study are discussed.
