This study employed a cross-lagged panel network model to examine the longitudinal relationships between problems of sleep, internalizing and externalizing problems in adolescents.

This study gathered data at four different time points (T1, T2, T3, and T4) for students enrolled in Grades 7 and 8, with an interval of approximately six months between each time point. The present sample comprised 1,281 Chinese adolescents, including 636 girls, with a mean age of 12.73 years (SD = 0.68) at baseline. Cross-lagged panel network modeling was used to estimate longitudinal relationships between symptoms at adjacent time points. Network replicability was assessed by comparing the T1→T2 network with the T2→T3 network and the T2→T3 network with the T3→T4 network.

The anxious/depressed symptom emerged as the most predictive of other symptoms and were also the most prospectively influenced by other symptoms. Cross-cluster edges predominantly flowed from internalizing and externalizing symptoms to sleep problems. Additionally, externalizing symptoms exhibited distinct patterns: aggression predicted more sleep and internalizing symptoms, whereas delinquent behavior predicted fewer of these issues.

These findings suggest that mental health problems contribute to later sleep disturbances, with internalizing symptoms playing a central role in adolescent psychopathology.
