Background:
Non-suicidal self-injury (NSSI) frequently co-occurs with major depressive disorder (MDD). This study aims to investigate the efficacy of dialectical behavior therapy skills training (DBT-ST) in treating major depressive disorder with non-suicidal self-injury (nsMDDs) under routine medication, as well as its modulatory effects on neural mechanisms.
Methods:
This assessor-masked, multicenter, randomized controlled trial enrolled 80 patients with nsMDDs from outpatient or inpatient departments of four hospitals. Participants were randomly assigned to receive either DBT-ST or social support group therapy (SSGT) once weekly for 13 weeks. NSSI severity, depressive severity, and spontaneous brain activity were assessed in both training groups before and after the intervention. The data analysis was conducted using SPSS 23 and MATLAB 2013a.
Results:
Findings demonstrated that both intervention groups were effective in alleviating clinical symptoms. Subgroup analyses by age revealed that DBT-ST demonstrated more significant improvements in NSSI behavior (B = 1.15, p < 0.001, d = -1.24) and depressive symptoms (B = 22.22, p < 0.001, d = -1.61) among adolescents (13 ~ 17 years old). Resting-state data revealed that following intervention, the DBT-ST group exhibited significantly reduced amplitude of low-frequency fluctuations (ALFF) in the right insula (F = 11.85, p = 0.003, d = 0.93) and regional homogeneity (ReHo) in the left insula (F = 18.48, p < 0.001, d = 1.24). Furthermore, following intervention, improvement in depressive symptoms within the DBT-ST group showed a significantly correlated with the reduction in ALFF in the right insula (r = 0.694, p = 0.038).
Conclusions:
DBT-ST may demonstrate superior applicability for improving clinical symptoms in adolescents with nsMDDs. Concurrently, DBT-ST may modulate abnormal spontaneous brain activity within neural circuits associated with nsMDDs. However, as this study did not track medication changes during the intervention period, the confounding effect of medication on neural alterations cannot be ruled out.
