To investigate the relationships between different dimensions of biological rhythm disorders, depression and anxiety symptoms among adolescents, and to identify the key dimensions that have a greater impact on mental health, providing a basis for developing targeted interventions.
Conducted from September to November 2023 in Tianjin, this study recruited middle school students from urban and suburban areas using convenience and stratified cluster sampling methods, yielding 3 787 valid questionnaires. The Self-rating Questionnaire of Biological Rhythm Disorders for Adolescents (SQBRDA), the Patient Health Questionnaire-9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7) were employed to assess biological rhythm disorders, depression, and anxiety symptoms, respectively. Network analysis was utilized to examine the association strengths between dimensions and to calculate centrality indices to pinpoint key nodes.
Activity rhythms showed higher centrality in the network (0.436), the edge weight between decreased interest and low mood was the largest in the depression symptom subnetwork (0.319), and the edge weight between persistent worry and excessive worry was the largest in the anxiety symptom subnetwork (0.446). In the biological rhythm subnetwork, the edge weight between activity rhythms and electronic product use rhythms was the largest (0.566). Females had stronger associations in the depression symptom network and the biological rhythm disorder network (0.194).
The study demonstrates a complex correlation network between adolescent biological rhythm disorders, depression and anxiety symptoms, especially activity rhythm and electronic product use rhythm.
