Objective To explore the influencing factors of self-stigma in adolescents mood disorders with non-suicidal self-injury behaviors (NSSI)and examine the chain mediating effect of self-esteem and social avoidance and distress between NSSI and self-stigma . Methods By convenience sampling method, 204 adolescents with mood disorders were evaluated by the Adolescent non-Suicidal Self-Injury Questionnaire(ANSSIQ), Internalized Stigma of Mental Illness Scale (ISMI), Rosenberg Self-Esteem Scale(RSES), Social Avoidance and Distress Scale (SADS), and Social Support Rating Scale (SSRS). Multiple linear regression was used to analyze the influencing factors of self-stigma in adolescent mood disorders with NSSI, and the SPSS PROCESS macro Model6 procedure was used to examine the mediating effects of self-esteem, social avoidance and distress on NSSI and self-stigma. Results ?The score of ISMI in mood disorder group with NSSI was higher than that without NSSI group (P < 0.001). The total ISMI score of patients with NSSI was significantly positively correlated with the ANSSIQ behavior scale score and SADS score (r=0.32, r=0.64, P < 0.01), and significantly negatively correlated with the total RSES score and SSRS score (r=-0.72, r=-0.55, P < 0.01). The results of multiple linear regression analysis showed that the regression equation was significant (P < 0.001), and NSSI severity (β=0.13, P < 0.05), social avoidance and distress (β=0.26, P < 0.01)) significantly predicted the total score of ISMI. Self-esteem level (β=-0.44, P < 0.01), social support (β=-0.17, P <0.01) significantly negatively predicted the total ISMI score, and these variables together explained 60.5% of the variation in self-stigma. Self-esteem, social avoidance and distress played a partial mediating role in the relationship between NSSI severity and self-stigma. The mediating effect was 0.24, accounting for 56% of the total effect. The indirect effect from NSSI→ self-esteem→self-stigma was 0.16. Conclusions NSSI severity, self-esteem, social avoidance and distress, and social support are important factors affecting self-stigma in adolescents with mood disorders associated with NSSI. The severity of NSSI can either directly affect self-stigma or indirectly affect through self-esteem, social avoidance and distress, especially the mediating role of self-esteem. |
