Core Tip

Core Tip: Latent profile analysis (LPA): Utilized LPA based on self-injury and patient health questionnaire-9 depression assessments to uncover distinct non-suicidal self-injury (NSSI) profiles in adolescents, addressing the hypothesized heterogeneity between NSSI with and without depression. Network analysis insights: Identified differences in risk and resilience factors across NSSI subgroups. Bullying and depression connection: Demonstrated a strong link between bullying and depressive symptoms in NSSI subgroups. Intervention focal points: Pinpointed emotional control and family support as key areas for targeted interventions derived from LPA findings.
