Abstract:

Objective To explore the effects of dialectical behavior therapy (DBT) combined with sertraline on the efficacy and coping styles of adolescent depression disorder with non-suicidal self-injury (NSSI). Methods From June 2020 to December 2021, patients with adolescent depressive disorder with NSSI who were hospitalized in Mental Hospital of Yunnan Province were enrolled in this study. According to the order of enrollment, the patients were divided into two groups, including: the combination group (35 cases) and the control group (35 cases). The control group received sertraline treatment, while the combination group received DBT and sertraline treatment. At baseline (T0), 6 weeks later (T1), and 6 months later (T2), the Hamilton Depression Scale (HAMD), Adolescent Non-suicidal Self-injury Assessment Questionnaire, Simplified Coping Style Questionnaire were used for measurement, and repeated measures analysis of variance was compared between the two groups. Results At T0, there was no significant difference in demographic data and questionnaire scores between the two groups (P>0.05). There were significant differences in total suicide score, HAMD, positive coping and negative coping scores between the two groups at T1 and T2 (P<0.05). The combination group showed a more significant decrease in total suicide score, HAMD and negative coping scores, whereas a more significant increase in positive coping score. The differences in total suicide score, HAMD and negative coping score between the two groups existed in the interaction of time point×group. Conclusion Providing DBT intervention to adolescent depression disorder patients with NSSI can lower HAMD score, reduce the occurrence of NSSI behavior, improve positive coping styles and discard negative coping styles, and have better durability.
