Nonmedical use of prescription opioids among college students is an underinvestigated phenomenon. Few studies have examined the etiology or factors associated with nascent prescription opioid misuse. The current investigation assessed substance-free activity reinforcement, activitiy engagement, and anhedonia in a sample of 54 college students who reported nonmedical use of prescription opioids compared to demographically similar controls. Self-reported substance-free sexual reinforcement measures indicated that opioid use was associated with greater substance-free sexual reinforcement. Behavioral choice measures indicated that opioid users chose to view drug-related images at a higher rate than drug-free images. Although there were no group differences on self-reported anhedonia symptoms, a behavioral measure of anhedonia indicated that opioid users rated objectively pleasant images as less pleasant comapared to the control group. College students who report drug use and deficits in anhedonic response to drug-free stimuli may be at risk for diminished engagement in a variety of alternative behaviors.
