A study of the symptom network structure of internet addiction, non-suicidal self-injury and internalization problems in adolescents and its association with physical activity

Social anxiety and interpersonal/health-related problems appear to be central drivers of comorbidity across IA, IP, and NSSI. Distress tolerance is closely linked to NSSI, while regular physical activity may buffer against IA, IP, and self-injurious behaviors. Targeted interventions focusing on these key symptoms are essential for promoting adolescent mental and physical well-being.
