Psychotherapies for Adolescents with Subclinical and Borderline Personality Disorder: A Systematic Review and Meta-Analysis

Abstract

Evidence regarding the efficacy of psychotherapy in adolescents with borderline personality disorder (BPD) symptomatology has not been previously synthesized. To conduct a systematic review and meta-analysis of the randomized controlled trials (RCTs) in order to assess the efficacy of psychotherapies in adolescents with BPD symptomatology. Seven electronic databases were systematically searched using the search terms BPD, adolescent, and psychotherapy from database inception to July 2019. Titles/abstracts and full-texts were screened by one reviewer; discrepancies were resolved via consensus. We extracted data on BPD symptomatology, including BPD symptoms, suicide attempts, nonsuicidal self-injury, general psychopathology, functional recovery, and treatment retention. Data were pooled using random-effects models. Of 536 papers, seven trials (643 participants) were eligible. Psychotherapy led to significant short-term improvements in BPD symptomatology posttreatment (g = -0.89 [-1.75, -0.02]) but not in follow-up (g = 0.06 [-0.26, 0.39]). There was no significant difference in treatment retention between the experimental and control groups overall (odds ratio [OR] 1.02, 95% confidence interval [CI], 0.92 to 1.12, I 2 = 52%). Psychotherapy reduced the frequency of nonsuicidal self-injury (OR = 0.34, 95% CI, 0.16 to 0.74) but not suicide attempts (OR = 1.03, 95% CI, 0.46 to 2.30). There is a growing variety of psychotherapeutic interventions for adolescents with BPD symptomatology that appears feasible and effective in the short term, but efficacy is not retained in follow-up-particularly for frequency of suicide attempts.
