Negative Consequences Related to Nonmedical Prescription Stimulant Use: Development and Psychometric Validation of the Prescription Stimulant Consequences Questionnaire.

Nonmedical prescription stimulant use (NPS) is prevalent among undergraduates and associated with several negative consequences. However, no validated measures exist assessing NPS-related consequences. The present study aimed to develop and psychometrically validate a Prescription Stimulant Consequences Questionnaire (PSCQ) for use among college students. A multisite sample of college students endorsing NPS (N = 715, 68.4% female) completed the PSCQ and measures of NPS frequency and correlates of NPS via an online survey. Exploratory factor analysis supported a 27-item measure, with three factors (i.e., Compulsive Behavior, Risky Behaviors, and Physical and Mental Health) and a total score. Each PSCQ factor and total score demonstrated good internal consistency, and were significantly positively associated with all NPS frequency indicators, route of administration, alcohol-related problems, sleep problems, and depressive/anxiety symptoms. Findings demonstrate support for the psychometric validity and reliability of the newly developed PSCQ, which may demonstrate potential as a screening and outcome measure for intervention.
