Nonmedical prescription drug use among US college students at a Midwest university: a partial test of social learning theory.

We estimate the prevalence of nonmedical prescription drug (NMPD) use and test social learning theory as an explanation for NMPD use based upon data from a large pilot study. Data were collected from 465 college students at a Midwestern university in the USA using a self-administered questionnaire. The sample was predominantly white (88%), 43% were female and the mean age was 22. Most participants (80%) were not members of social fraternities or sororities. A majority of students did not report NMPD use: 39.4% of respondents reported lifetime NMPD use, 31% reported past-year use, and 14.4% reported past-month use. Multivariate regression results partially supported social learning theory as an explanation for lifetime NMPD use. Limitations and suggestions for future research are suggested.
