Secondary Outcomes
The GEE model showed that sleep quality and job burnout scores in the intervention group were significantly lower than those in the control group at T5 and T6. In contrast, the work performance scores were significantly higher in the intervention group than in the control group at T6. Notably, the intergroup effect sizes for sleep quality at T5 and T6 were 0.75 (95% CI 0.41-1.08) and 0.81 (95% CI 0.47-1.15), respectively, indicating medium to large effect sizes (
