Abstract
Although a few studies have examined sleep knowledge and attitudes as predictors of sleep behavior, the question of which better predicts actual sleep behavior is still open. Furthermore, the construct of sleep attitudes has been inconsistently defined and measured. We examined both sleep knowledge and attitudes to determine their unique associations with sleep hygiene behaviors, and direct and indirect associations with objective and subjective sleep outcomes. College students (N = 218) completed a series of questionnaires before and after wearing a FitBit Flex accelerometer for 7 days. We collected objective sleep duration and quality using this apparatus, while participants reported subjective sleep outcomes, hygiene behaviors, knowledge, and attitudes. Analyses controlled for self-reported depression, diagnosed sleep disorder, and sleep-related medications. For both objective and subjective measures, more positive sleep attitudes but not greater sleep knowledge was directly associated with longer sleep duration, and indirectly (through sleep hygiene) with better sleep quality. The role of sleep attitudes in sleep-related behaviors and outcomes deserves further investigation as a potentially modifiable factor in sleep intervention efforts.
