DBT skills validated again
Dialectical Behavior Therapy skills training is now supported by 13 randomized clinical trials, reinforcing its effectiveness for emotion regulation, distress tolerance, and mood symptoms. (psychiatrictimes.com)
Linehan and colleagues conducted a multi-arm component randomized trial (enrollment 2004–2010) that randomized 99 women with borderline personality disorder to standard DBT, skills training plus case management (DBT‑S), or individual therapy plus activities group, with one year of treatment and one year of follow-up reported in JAMA Psychiatry (2015). (jamanetwork.com) A mediator analysis across three randomized trials found that participants receiving DBT reported roughly three times more DBT skills use at four months and that increased skills use statistically mediated reductions in suicide attempts and depressive symptoms (Neacsiu et al., Behaviour Research and Therapy, 2010). (sciencedirect.com) A pragmatic randomized trial by McMain and colleagues randomized 84 suicidal outpatients to 20 weeks of brief DBT skills training versus waitlist and reported greater reductions in suicidal and non‑suicidal self‑injury episodes and improved distress tolerance and emotion regulation at 32‑week follow‑up. (europepmc.org) Soler et al. ran a 3‑month RCT of 60 outpatients with BPD comparing 13 weekly DBT skills sessions against an equal‑dose standard group therapy and reported superiority of the DBT‑ST arm on multiple BPD symptom measures at three months. (sciencedirect.com) A large pragmatic trial published in JAMA (2022) randomized 18,882 outpatients with frequent suicidal ideation across four U.S. health systems to care management, an online DBT skills training offer, or usual care and found 18‑month nonfatal/fatal self‑harm rates of 3.3%, 3.9%, and 3.1% respectively, with the online‑skills offer showing a statistically significant increase in self‑harm versus usual care. (jamanetwork.com) Published trials and reviews document wide heterogeneity in delivery: single‑session RCTs (BMC Psychology, 2016), pilot transdiagnostic DBT‑ST trials with mixed protocol adherence (Behaviour Research and Therapy, 2014), and school‑based implementations that show inconsistent effects in adolescent universal programs (Springer review, 2025).
