Abstract

To examine the associations between poor sleep quality and sociodemographic characteristics, sleep hygiene, sleep deprivation, and mental health among undergraduate psychology students at a Brazilian university. This was a quantitative descriptive cross-sectional study with a convenience sample of 130 psychology students (73.8% women, M=21, SD=2.6). Participants completed measures on sociodemographic characteristics, sleep quality, deprivation, and hygiene, health behaviors, self-efficacy, and stress. Multiple regression analysis using Wald chi-square test demonstrated that male sex (p<.01), older age (p<.05), higher stress (p<.001), and non-smoking (p<.05) were associated with poorer sleep quality, while greater weekly working hours (p<.01), better sleep hygiene (p<.05), and higher self-efficacy (p<.05) were associated with better sleep quality. Findings reiterate the relevance of social, psychological, and behavioral factors in comprehending sleep quality.
