ABSTRACT
BACKGROUND: Social isolation has emerged as an increasingly critical public health issue among adolescents with depression. This study aimed to identify latent subgroups of social isolation based on its manifestations among adolescent patients with depression and to explore the associated influencing factors.
METHODS: A cross-sectional study was conducted from August 2024 to March 2025 at a specialized psychiatric hospital in Nanjing, China. Data were collected using paper-based questionnaires, which included demographic characteristics, the General Social Alienation Scale (GSAS), the Patient Health Questionnaire for Adolescents (PHQ-A), and the Resilience Scale for Chinese Adolescents (RSCA). Latent profile analysis (LPA) was used to classify patterns of social isolation. Chi-square tests, analysis of variance (ANOVA), lasso regression, and multinomial logistic regression were used to analyze profile characteristics and their influencing factors.
RESULTS: A total of 412 adolescent patients with depression were included. This study identified three distinct profiles of social isolation: “Low isolation – Fluctuating group” (24.7 %, n = 102), “Moderate isolation – Skeptical group” (39.6 %, n = 163), and “High isolation – Avoidant group” (35.7 %, n = 147). Patients were significantly more likely to be classified into the “High isolation – Avoidant group” if they had siblings, a longer duration of mental illness, more severe depressive symptoms, or lower psychological resilience (all p < 0.05).
CONCLUSIONS: This study revealed the heterogeneity of social isolation among adolescents with depression through LPA and identified key influencing factors. These findings provide a theoretical foundation for the development of tailored intervention strategies.
