    Author: Clegg-Kraynok MM, McBean AL, Montgomery-Downs HE.
    Journal: Sleep Med; 2011 Jun; 12(6):598-602. PubMed ID: 21645874.
    Abstract:
    OBJECTIVE: Although psychostimulants have been shown to affect sleep in experimental studies, the relation between nonmedical psychostimulant use and sleep has not been examined. Our goal was to describe the sleep quality and characteristics of college students who use psychostimulant medications nonmedically. METHODS: We surveyed 492 college students about their sleep quality and psychostimulant use characteristics. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI); psychostimulant use and characteristics were measured via a survey developed for this study. RESULTS: College students who self-reported current or a history of nonmedical psychostimulant use reported worse subjective sleep quality, sleep disturbance, and global PSQI scores than nonusers. The most commonly reported reason for nonmedical psychostimulant use was to improve work performance and concentration. CONCLUSIONS: These data demonstrate worse sleep quality among nonmedical psychostimulant users. The likely consequence of increased daytime sleepiness helps to confirm the known public health concern of nonmedical prescription psychostimulant use among college students.
