University students and "the all nighter": correlates and patterns of students' engagement in a single night of total sleep deprivation.
This study evaluated the self-reported patterns, motivations, and correlates of engagement in a single night of total sleep deprivation (SN-TSD) in a sample of 120 university students at a 4-year liberal arts college. Participants' mean age . was 20.1 years; the sample was 63% female. Measures included the Owl-Lark Scale of circadian preference; the Beck Depression Inventory; and the Pittsburgh Sleep Quality Index (PSQI); as well as self-reported usual bedtime, rise time, and total sleep time. Students' cumulative grade point averages (GPAs) were also obtained; these were reported from the university registrar. Sixty percent of students surveyed reported engaging in SN-TSD once or more since coming to college. No differences between genders or among class standing with respect to use of SN-TSD were detected. Engagement in SN-TSD was associated with later self-reported bedtimes, evening preference, and poorer academic achievement as measured by GPA. A trend for increased symptoms of depression was detected; sleep quality as measured by the PSQI was not related to engagement in SN-TSD.
