Pros and cons: prospective predictors of marijuana use on a college campus.
Marijuana use on college campuses is prevalent and associated with high rates of abuse and dependence. The Marijuana Decisional Balance (MDB) scales measure perceived pros and cons toward marijuana use. Evidence supports reliability and concurrent validity of these scales, but the predictive validity has not yet been assessed. ⋯ Pros and cons showed strong test-retest reliability (rs = 0.80-0.85) and internal consistency (alphas = 0.92-0.95). In a college sample, pros and cons of marijuana use demonstrated stability over one month, and prospectively predicted use. Pros may also have utility in predicting problems and dependence potential on college campuses.
