Effects of Workshop Training in the Dialectical Behavior Therapy Prolonged Exposure Protocol on Clinician Beliefs, Adoption, and Perceived Clinical Outcomes

Although extensive efforts have been made to train clinicians in evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD), relatively few PTSD patients are considered appropriate for and therefore receive these treatments. The dialectical behavior therapy prolonged exposure (DBT PE) protocol was developed to expand the reach of EBPs for PTSD to suicidal patients with severe comorbidities, but methods of training clinicians to deliver this treatment have not been evaluated. We examined the impact of DBT PE workshops on clinician beliefs, adoption, and perceived patient outcomes. Clinicians (N = 266) attended 2- or 4-day workshops and completed surveys at pretraining, posttraining, and 3- and 6-month follow-ups. From pretraining to 6-month follow-up, there were significant improvements in clinician concerns regarding worsening, perceived treatment credibility, and self-efficacy that did not differ by workshop length, R(2)s = .20-.45. At 6-months posttraining, 53.5% of clinicians (38.8% 2-day, 66.3% 4-day) reported using DBT PE with 241 patients. Higher posttraining ratings of self-efficacy and perceived treatment credibility at predicted later DBT PE use, R-2 = .28. Among adopting clinicians, 81.3% reported that, on average, their patients' PTSD improved and 66.7% reported that patients were much to very much improved on average. Most clinicians reported that their patients' comorbid problems did not worsen during DBT PE and if worsening occurred, it typically involved temporary increases in distress. Workshops may be an effective method of changing clinician beliefs and promoting the use of DBT PE in a manner that clinicians experience as effective and safe for their patients.
