Predictors of sleep quality: Depression, anxiety, and sleep self-efficacy

The objective of the current study was to examine the relationship between depression, anxiety, sleep self-efficacy and sleep quality in college students by using both objective measures and self-report data. Participants included undergraduate students from a small liberal arts college who wore an ActiGraph wGT3X-BT wristband for a period of seven nights. At the end of the seven nights, participants also completed the Beck Anxiety Inventory, Center for Epidemiologic Studies Depression Scale, the Sleep Self-Efficacy Scale, and Pittsburgh Sleep Quality Index. Results indicated that higher sleep self-efficacy scores were associated with lower anxiety and depression scores. Higher self-reported sleep quality, based on the Pittsburgh Sleep Quality Index, was also associated with higher sleep self-efficacy scores as well as lower depression and anxiety scores. Results were potentially limited due to the small sample size (n = 20) of the study, as well as participant bias and various environmental factors that will be discussed
