Abstract

Nonmedical prescription opioid (NMPO) use is elevated among emerging adults and may be related to deficits in executive cognitive functioning (ECF). This study examined relations between NMPO use, ECF deficits, and "downstream consequences" of poor self- and emotion regulation among emerging adults. Twenty-seven emerging adult NMPO users and 27 matched controls completed measures of ECF (working memory and interference control), self- and emotion regulation, and a clinical interview assessing substance use. NMPO users reported regulation deficits relative to controls, but groups did not differ on ECF measures. Among users, interference control was associated with NMPO use, working memory with alcohol use severity, and emotion regulation with NMPO use severity and marijuana use. Across groups, goal-directed and implusive behavior when distressed was associated with interference control. Engagement in goal-directed behavior when distressed was additionally associated with working memory. These findings should be extended to inform research, preveniton, and intervention.
