Evaluation of Perceived Depression, Anxiety, Stress Levels, Sleep Quality and Quality of Life among Adults During the COVID-19 Pandemic

Abstract

Objective: This study aimed to determine sleep quality, depression, anxiety, stress, and quality of life scores among Turkish adults during the pandemic and to examine the correlations among these variables. Material and Method: This online cross-sectional study was completed with 962 adults aged ≥18 years. The data collection form included questions about demographic and anthropometric characteristics, Pittsburgh Sleep Quality Index (PSQI), The World Health Organization Quality of Life Scale-Short Form (WHOQoL-BREF), and Depression Anxiety Stress Scales (DASS-42). The snowball sampling method was used. Results: The median DASS and PSQI scores were higher in participants with poor sleep quality and sleep duration less than 7 hours (p<0.05). All subscales of the WHOQoL were significantly higher in individuals with good sleep quality and the general, physical, and psychological subscales were significantly higher in individuals with sleep duration of 7 hours or more (p<0.05). Age was found to have a weak correlation with the DASS subscales and a very weak correlation with the PSQI. There was a positive and moderately significant correlation between PSQI and the DASS subscales (p<0.001). Body weight and BMI had very weak correlation with DASS-D, DASS-A, and PSQI subscales (p<0.05). All subscales of WHOQoL were found to be negatively correlated with DASS subscales and PSQI (p<0.05). Conclusion: Quality of life was significantly correlated with perceived depression, anxiety, and stress, and sleep quality. There was also a correlation between sleep quality and levels of depression, anxiety and stress.
