N2  - OBJECTIVE: We examined the trajectories of sleep problems in adolescents after the Wenchuan earthquake, and assessed predictors such as posttraumatic stress disorder symptoms. <br><br>METHODS: We surveyed adolescents at 1, 1.5, 2, and 2.5 years after the Wenchuan earthquake. In total, 391 adolescents completed self-report questionnaires. <br><br>RESULTS: We identified five latent sleep problem trajectories, specifically, U-shaped (3.8%), low-stable (68.0%), high-stable (10.8%), increasing (8.7%), and decreasing (8.7%) trajectories. Additionally, we found that posttraumatic stress disorder hyper-arousal symptoms were more frequent in individuals who had non-low-stable trajectories. Adolescents in the U-shaped group were less likely to have intrusive symptoms. <br><br>CONCLUSION: After natural disasters, consequent sleep problems in adolescents do not remain stable over time, and sleep problem trajectories had considerable heterogeneity.<p />  <p>Language: en</p>
