Abstract
|
|
|
Background and Objective Sleep disturbances among medical students, including insufficient sleep duration and poor sleep quality, are prevalent issues with potential repercussions on mental health.
Methods The study evaluated the Vietnamese version of the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality and investigated the correlation between the results of the PSQI and Beck Depression Inventory-II (BDI-II) scales in health sciences students.
Results We conducted this cross-sectional study at the School of Medicine, Vietnam National University Ho Chi Minh City, involving 906 medical, pharmaceutical, and dental students. Data were collected through a self-reporting questionnaire
Conclusions The Vietnamese version of the PSQI scale demonstrates acceptable reliability. Furthermore, positive correlations were observed between the total PSQI score and components of the BDI-II. A recommended cut-off point above 5 is proposed for identifying sleep disturbances among health sciences students using the Vietnamese PSQI. Conclusions The study affirms the reliability of the Vietnamese PSQI scale, suggesting its suitability for screening sleep disturbances among health sciences students in Vietnam. PSQI component scores significantly correlated with total BDI-II score.
