BACKGROUND: Difficulties in coping with stress and regulating emotions are transdiagnostic risk factors for self-harming behavior. Due to sociocultural stressors, ethnic minority adolescents may be at greater risk for self-regulation difficulties and self-harm. Dialectical behavior therapy for adolescents (DBT-A) frames adaptive skill acquisition as a mechanism of change, but few studies have investigated its impact on ethnic minority adolescents' self-regulation (i.e. coping, emotion regulation). Therefore, this pilot study examined relations between self-regulation and self-harm among ethnic minority adolescents and investigated changes in their self-regulation upon completing DBT-A.
METHODS: A clinically referred sample of 101 ethnic minority adolescents (Mage = 14.77; female = 69.3%) completed questionnaires about a history of self-harm, coping (DBT Ways of Coping Checklist), and emotion regulation (Difficulties in Emotion Regulation Scale). Of the initial sample, 51 adolescents (Mage = 14.73; female = 80.4%) entered a 20-week DBT-A program due to self-harm and/or Borderline Personality features.
RESULTS: In a pretreatment sample, the frequency of dysfunctional coping, but not of adaptive coping, differentiated self-injurers from non-self-injurers. Full information maximum likelihood estimation was used to address high attrition (60.8%) from DBT-A. Those who completed DBT-A (n = 20) reported significantly improved emotion regulation. Adaptive coping at pretreatment predicted increased DBT skills use at post-treatment.
CONCLUSIONS: This non-randomized pilot study highlights dysfunctional coping and emotion dysregulation as risk factors for self-harm and suggests that 20-week DBT-A may help improve emotion regulation. Future research should employ a randomized design to further examine the effect of DBT-A on these transdiagnostic processes of psychopathology.
KEY PRACTITIONER MESSAGE: Due to cultural and environmental stressors, ethnic minority adolescents may be at greater risk for developing self-regulatory difficulties - transdiagnostic mechanisms known to underly self-harming behaviors; however, we know little about whether empirically supported treatments for self-harm will improve youth's coping and emotion regulation. In a clinically referred, pretreatment sample of ethnic minority youth, levels of BPD symptomatology, emotion dysregulation, and dysfunctional coping, but not of adaptive coping, differentiated teens who self-harmed from those who did not. Self-harming ethnic minority youth who participated in an uncontrolled, pilot trial of dialectical behavior therapy for adolescents (DBT-A) at an urban mental health clinic reported improved emotion regulation at post-treatment. Baseline emotion regulation skills were not predictive of treatment-related changes, suggesting that other factors, such as DBT-A, may have played a decisive role in improving teens' emotion regulation. In contrast, adaptive coping skills at pretreatment were linked to increased DBT skills use at post-treatment, indicating that patients' baseline coping skills may play a predictive role in psychotherapy outcomes. Future research should employ a randomized control trial to examine the effect of DBT-A on vulnerable ethnic minority youth's development of self-regulation. It should also investigate the hypothesized mediating role of self-regulation in effecting lasting clinical gains.
