How does parental psychological control influence adolescent depression? A sequential mediation and network analysis of smartphone addiction and sleep disturbance

These findings elucidate the mechanisms through which parental psychological control contributes to adolescent depression, yielding significant theoretical and practical implications for adolescent mental health preventive interventions. Specifically, interventions targeting maladaptive smartphone use and poor sleep hygiene, particularly those addressing intermediary symptoms such as daytime dysfunction, may effectively mitigate the risk of depression in adolescents under high parental psychological control.
