ABSTRACT
OBJECTIVE: Growing research highlights the negative impact of sleep problems on adolescent mental health. However, the developmental trajectory of sleep problems during adolescence and their relationship with mental health difficulties, including both internalizing and externalizing symptoms, remain unclear. Additionally, the direction of the effects between sleep problems and mental health difficulties is not well established. This study aims to identify the developmental trajectories of sleep problems and examine their association with mental health difficulties in both internalizing and externalizing domains.
METHOD: The study involved 1,281 Chinese middle school students (645 males, mean age at initial assessment = 12.73, SD = 0.68). Data were collected at four time points (T1, T2, T3, T4) over approximately 6-month intervals, spanning from the first semester of seventh grade to the second semester of 8th grade.
RESULTS: Latent growth modeling revealed an overall increasing trend in sleep problems. Parallel latent growth modeling indicated that trajectories of sleep problems were positively related to the developmental trends of mental health difficulties, as shown by intercept-intercept and slope-slope associations. The cross-lagged panel model demonstrated significant bidirectional associations between sleep problems and internalizing symptoms. In contrast, we observed unidirectional associations between sleep problems and externalizing symptoms. Hence, sleep problems were a significant predictor of subsequent externalizing symptoms, with no significant reverse effect observed.
CONCLUSION: These findings suggest that future research should explore whether interventions targeting sleep problems can reduce the incidence of both internalizing and externalizing symptoms. Additionally, interventions aimed at internalizing symptoms may potentially improve adolescent sleep, while those targeting externalizing symptoms may not have the same effect.
