Efficacy of dialectical behaviour therapy for adolescents

The current review provides a qualitative assessment of the efficacy of dialectical behaviour therapy (DBT) as adapted for adolescents. The aim was to assess the efficacy of DBT compared to usual methods in the treatment of adolescent mental health symptoms, inclusive of suicidal ideation and self‐harm. Computerised databases including Medline and PsycINFO were accessed and knowledgeable informants in the area of DBT were contacted. Inclusion criteria required the studies to be clinical trials on DBT provided to adolescents. Due to the requirements on research design only three studies were appropriate for review. The review focused on quality assessment of the current data, including investigation into the effects of selection bias, confounding variables, outcome measures and measurement errors. The data suggest that there is some evidence for DBT being effective in reducing symptoms of mental health, especially those consistent with borderline personality disorder. The resultant data, however, are of very poor quality, and as such the review addresses ways to improve the quality of research and offers suggestions for future research.
