Who Persists and Who Desists? A Prospective Study of Prescription Stimulant Misuse in College Graduates [post-print]

Abstract

Prescription stimulant misuse (PSM) has been studied extensively in college populations, but few studies have examined how PSM changes after graduation. We used a longitudinal design to follow individuals at risk for PSM two years after college graduation to document PSM prevalence, motives, and predictors of PSM persistence. Participants from two small, private colleges completed online surveys focused on intrapersonal, interpersonal, and sociocultural predictors of PSM. Overall, PSM declined over time. Lack of premeditation, perceived peer norms, positive expectancies, media exposure, and other substance use were associated with continued PSM; however, only lack of premeditation, descriptive norms, and other substance use predicted PSM in a multivariate model. This preliminary study suggests dispositional and behavioral risk factors may help to explain why PSM persists after college. Interventions that enhance decision-making skills, correct misperceptions about peers\u27 PSM, and reduce polysubstance use may be effective in curbing PSM in college graduates
