OBJECTIVES: Accurate assessment of sleep quality is crucial for understanding sleep problems and their impact on health. This study analyzed the agreement between subjective sleep assessments and objective sleep monitoring in adolescents with mood disorders, aiming to provide a reliable methodological foundation for related research. METHODS: Adolescents with mood disorders were recruited from psychiatric outpatient clinics of three domestic hospitals. A consensus sleep diary and an actigraph (activity tracker) were used to monitor sleep for 14 days. The differences between subjective and objective measurements were compared using the Wilcoxon signed-rank test, while Bland-Altman plots and intraclass correlation coefficients (ICC), described their agreement. Spearman's rank correlation coefficients were used to assess their correlation, and mixed-effects models analyzed factors influencing the differences between subjective and objective measurements. CONCLUSIONS: Considerable discrepancies remain between subjective sleep diaries and sleep monitoring data from actigraphy (activity tracker). Future research should further investigate factors influencing the discrepancies between subjective and objective measurements and refine measurement methods to obtain more reliable sleep data.
