To investigate the relationship between common psychiatric disorders ( CPD s) and sleep characteristics (evening chronotype, poor sleep quality and daytime sleepiness) among T hai college students. Methods A cross‐sectional study was conducted among 2,970 undergraduate students in T hailand. Students were asked to complete a self‐administered questionnaire that collected information about lifestyle and demographic characteristics. The H orne and O stberg M orningness– E veningness Q uestionnaire ( MEQ ), P ittsburgh S leep Q uality I ndex ( PSQI ) and E pworth S leepiness S cale ( ESS ) were used to evaluate circadian preference, sleep quality and daytime sleepiness, respectively. The G eneral H ealth Q uestionnaire‐12 ( GHQ ‐12) was used to evaluate presence of CPD s. Logistic regression models were used to estimate adjusted odds ratios ( ORs ) and 95% confidence intervals (95% CIs ) of CPD s in relation to the covariates of interest. Results A total of 337 students were classified as having CPD s (11.2%; 95% CI 10.1–12.3%). Evening chronotype ( OR = 3.35; 95% CI 2.09–5.37), poor sleep quality ( OR = 4.89; 95% CI 3.66–6.54) and excessive daytime sleepiness ( OR = 1.95; 95% CI 1.54–2.47) were statistically significantly associated with CPD s. Discussion Our study demonstrated that CPD s are common among T hai college students. Further, evening chronotype, poor sleep quality and excessive daytime sleepiness were strongly associated with increased risk of CPD s. These findings highlight the importance of educating students and school administrators about the importance of sleep and their impact on mental health.
