Abstract
The purpose of the study was to identify a stable model of psychosocial variables related to cocaine use among college students. Development and validation of this model could contribute to a useful cocaine abuse risk profile for college students. Of the 683 students who participated in the study, 179 reported using cocaine at least once in their life on an anonymous survey. The relationship between an index of cocaine use (coef. alpha = .79) and eight psychosocial variables was examined using a multiple regression procedure. The results indicated that two variables, perceived academic ability and interest in school, were significantly associated with scores on the cocaine index. Cross-validation procedures, including Tukey's Jackknife method, were conducted to ascertain the stability of the multiple regression model based on changes in the R-Squared value. The implications for future research and prevention programming efforts are discussed.
