Application Research of "Internet+" Dialectical Behavior Therapy Intervention Mode in Adolescent Non-suicidal Self-injury Intervention

Abstract

Background Adolescent non-suicidal self-injury has become an increasingly serious mental health problem, and its course is protracted, causing serious burdens to patients, families and society. Intervention of non-suicidal self-injury in adolescents requires a comprehensive intervention model, and the practice of online intervention management in China is still in its infancy. Objective To investigate the intervention effect of "Internet+" dialectical behavior therapy (DBT) on suicidal ideation, cognitive emotion regulation, and alleviation of depression in adolescent patients with non-suicidal self-injury. Methods A total of 120 adolescent patients with non-suicidal self-injury who were discharged from the Second Affiliated Hospital of Xinxiang Medical University from May 2021 to May 2022 were selected and randomly divided into the control group (n=60) and intervention group by randomized controlled single-blind method (n=60). The control group received drug intervention, telephone follow-up and psychological counseling, the intervention group implemented a one-year "Internet+" DBT training based on the control group, which was divided into 4 modules of mindfulness training, interpersonal effectiveness training, emotion regulation training and pain tolerance training. Before the intervention, 6 months and 12 months after the intervention, the Self-rating Idea of Suicide Scale (SIOSS), Chinese version of Cognitive Emotion Regulation Questionnaire, (CERQ-C) and Montgomery and Asberg Depression Rating Scale (MADRS) were used to evaluate the suicidal ideation, cognitive emotion regulation, and depression status of the two groups of patients. Repeated measures analysis of variance was used to compare the health status of the two groups at different time points. Results Finally, 57 cases in the control group and 55 cases in the intervention group completed the study. There was an interaction between group and time on SIOSS, CERQ-C, and MADRS scores (P<0.05) ; the main effect of group on SIOSS, CERQ-C, and MADRS scores was significant (P<0.05), and the main effect of time on SIOSS, CERQ-C, and MADRS scores was significant (P<0.05). Among them, the difference was statistically significant when comparing the SIOSS, CERQ-C, and MADRS scores before and after intervention within the intervention group (P<0.001) ; there was no significant difference in positive refocus, refocusing on planning, positive reappraisal, rational analysis, catastrophizing, and blaming others dimensions in the SIOSS scores, MADRS scores, and CERQ-C scores before and after intervention within the control group (P>0.001). The difference was statistically significant when comparing the self-blame, acceptance, and contemplation dimensions of the CERQ-C scores before and after intervention within the control group (P<0.001) . Conclusion The "Internet+" DBT intervention model can effectively reduce the suicidal ideation of adolescent patients with non-suicidal self-injury, improve the level of emotional control, relieve depression, and improve the quality of life and social function of patients.
