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 (M
age = 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 (M
age = 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.
