College students are sleeping less during the week than reported a few years ago. Lack of sleep among college students has been identified as one of the top three health related impediments to academic performance by the American College Health Association's National College Health Assessment survey; and it is associated with lower grades, incompletion of courses, as well as negative moods. This research examines the underlying dynamics of lack of sleep on academic motivation, a key predictor of academic performance. Specifically, the relationship of sleep habits with self-efficacy, performance versus mastery goal orientation, persistence, and tendency to procrastinate were investigated. Findings indicate that 42% of the participants (159 students out of a total of 377) experience excessive daytime sleepiness (EDS); and those identified with EDS tend: (1) to be motivated by performance goals rather than mastery goals; (2) to engage in procrastination (a self-handicapping strategy) to a greater extent than students who are rested; and (3) to have decreased self-efficacy, as compared to students not reporting EDS. Several recommendations for campus health professionals to consider for a Healthy Campus Initiative are made based on the findings. (Contains 1 table.)
