Abstract:Excessive daytime sleepiness (EDS) is one of the most prevalent sleep-related problems, known for causing impairments in functioning which often leads to decreased occupational performance and is one of the leading contributors to motor vehicle accidents. Certain substances are known to induce EDS or to worsen its symptoms in users. In this study, the severity of psychoactive substance use (SPSU) and EDS in a sample of 137 young adults were examined with the goal of determining the correlational relationship between EDS, SPSU, and caffeine consumption. A questionnaire was created in order to assess these variables, including an adaptation of the Epworth Sleepiness Scale (ESS) and the Tobacco, Alcohol, Prescription medications, and other Substances (TAPS) Tool. Calculation of the correlations was facilitated by regression analyses of the variables. In the general sample, caffeine consumption was positively correlated to SPSU, and EDS was neither correlated to general SPSU, nor did it show a correlation to caffeine consumption. However, a weak positive correlation between employment types and SPSU was found. Contrary to the hypotheses, SPSU or caffeine consumption could not predict EDS in the general population.
