Abstract:
BackgroundSchool bullying is a serious social issue. Non-suicidal self-injury （NSSI） is a highly prevalent behavior among adolescents with depression and is also becoming a great matter of concern. Previous studies have proved a very close correlation among school bullying， experiential avoidance， family functioning， and NSSI behavior. However， there is a considerable lack of research on the moderating role of family functioning in the relationship between school bullying and experiential avoidance in adolescents with depression in China. ObjectiveTo explore the mediating role of experiential avoidance in the relationship between school bullying and NSSI in adolescents with depressive disorder， and the moderating role of family functioning in the relationship between school bullying and experiential avoidance， so as to provide references for formulating intervention strategies for NSSI in adolescents with depressive disorder. MethodsFrom January to December 2024， 318 consecutive adolescent patients fulfilling the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria for depression and attending the outpatient department of Weifang Mental Health Center were selected. All respondents completed the Delaware Bullying Victimization Scale-Student （DBVS-S）， Acceptance and Action Questionnaire-II （AAQ-II）， Family Assessment Device （FAD）， and Behavioral Questionnaire in the Adolescent Non-suicidal Self-injury Assessment Questionnaire （ANSAQ）. Pearson correlation was used to examine the relationship among variables. SPSS Process Macro v4.1 package program was utilized to seek the mediating and moderating effects. ResultsData were collected from 306 valid respondents （96.23%）. In adolescent with depressive disorder， DBVS-S score was positively correlated with both the behavioral questionnaire score in the ANSAQ and the AAQ-II score （r=0.357， 0.558， P<0.01）. AAQ-II score was positively correlated with the behavioral questionnaire score in the ANSAQ （r=0.380， P<0.01）. Experiential avoidance partially mediated the relationship between school bullying and NSSI in adolescents with depressive disorder， and the mediating effect value was 0.142 （95% CI： 0.081~0.204）. Family functioning moderated the relationship between school bullying and experiential avoidance， and the moderated mediation value was 0.096 （95% CI： 0.042~0.165）. ConclusionMediation is found from school bullying to NSSI behavior through experiential avoidance in adolescents with depressive disorder， and family functioning plays a moderating role in the relationship between school bullying and experiential avoidance.
