Objective: To understand the effect of dialectical behavior therapy (DBT) on adolescent depression with non-suicidal self-harm, and to provide a basis for in-depth research and promotion of DBT. Methods: Patients who met the diagnostic criteria of DSM-5 depression and were accompanied by non-suicidal self-harm were included as the study group (n=13), and the patients who met the diagnostic criteria of DSM-5 depression and were accompanied by non-suicidal self-harm by medication alone were selected. The injured patients served as the control group (n=13). Use the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Ottawa Self-Injury Scale (OSI), Acceptance and Action Questionnaire (AAQ-II), Adolescent Avoidance and Integration Questionnaire (AFQ-Y8) Group anxiety and depression degree, self-harm behavior and psychological flexibility. Results: After 6 weeks of treatment, the SAS score and SDS score of the study group were lower than those of the control group (both P<0.01). Logistic regression results show that the degree of mental rigidity has an impact on the resistance of individuals to self-harm behavior. The results of the chi-square test showed that the level of non-suicidal self-injury behavior was associated with the SAS score and SDS score respectively. The results of non-parametric test showed that the level of non-suicidal self-injury behavior between the study group and the control group was significantly different after treatment.
