Finally, the data were analyzed using Pearson correlation coefficient and stepwise regression in SPSS software (P ≤ 0.05). Findings: Based on the results obtained by regression analysis, psychological well-being was able to predict sleep quality (P = 0.011, F = 6.54, R2 = 0.030). Among the psychological well-being variables, “environmental mastery” (P = 0.001, T = -5.379, R2 = 0.120) had the highest ability to predict sleep problems in high school students during COVID-19 quarantine.
