Abstract:
Objective:To explore the efficacy of dialectical behavior therapy (DBT) in treating self-injury among adolescents with depressive disorders, and to examine the influencing factors of the efficacy.Methods:Fifty-five depressive adolescent in-patients with self-injury behaviors, admitted to the Qingdao Mental Health Center between December 2022 and June 2024 were enrolled and received dialectical behaviour therapy (DBT). Pre- and post-treatment assessments were conducted with a self-compiled questionnaire, Hamilton depression scale-17(HAMD-17), family adaptability and cohesion scale (FACES Ⅱ-CV), simplified coping style questionnaire (SCSQ), and self-injurious thoughts and behaviours interview (SITBI) in all patients.Based on the magnitude of reduction in self-injury after treatment, participants were classified into high-reduction group ( n=17), moderate-reduction group ( n=28), and low-reduction group ( n=10). SPSS 27.0 software was used to perform one-way ANOVA, Spearman correlation analysis and Logistic regression analysis to examine the effects of sex, only-child status, parental divorce, family cohesion and adaptability, and coping style on DBT efficacy. Results:The HAMD-17 score before treatment was 20.0(18.0, 22.0), and the score dropped to 7.0(5.0, 11.0) after treatment, and the difference was statistically significant ( Z=-6.460, P<0.01), yielding the reduction rate of (44.8±0.2)%.Self-injury frequency fell from a median of 5.0(2.0, 9.5) episodes per week before treatment to 0(0, 1.8) after treatment, and this decrease was also significant ( Z=-4.945, P<0.01), representing the reduction rate of (81.6±0.2)%. High positive coping styles ( OR=0.690, P=0.008) and strong family cohesion ( OR=0.491, P=0.007) were associated with better treatment efficacy. Conclusion:DBT can reduce the self-injury behaviors in adolescents with depressive disorders. High family cohesion and the use of positive coping strategies are important factors influencing the therapeutic effect.
