This study examined the efficacy of Developmentally Adapted Cognitive Processing Therapy (D-CPT) in adolescents and young adults with PTSD and explored the association between therapeutic adherence and competence with symptom reduction. The study found that neither adherence nor competence were related to symptom reduction, while therapeutic alliance was associated with symptom reduction.
Background: Developmentally adapted cognitive processing therapy (D-CPT) is an effective treatment for posttraumatic stress disorder (PTSD) in adolescents and young adults. It is unclear if therapeutic adherence and competence in D-CPT are associated with higher PTSD treatment gains.Objective: To assess if higher therapeutic adherence and competence in D-CPT are associated with higher symptom reduction of PTSD in adolescents and young adults, while controlling for ther-apeutic alliance. Participants and setting: Participants were 38 patients (aged 14-21 years; M = 17.61 years, SD = 2.42 years) of a multicenter randomized controlled trial in which the efficacy of D-CPT was compared to a waitlist with treatment advice.Methods: Videotaped therapy sessions were rated using validated ratings scales to assess adher-ence and competence. Therapeutic alliance was assessed via weekly patient ratings. We used hierarchical linear modelling to assess the relationship of adherence and competence on PTSD symptoms being measured by both clinician and patient while controlling for alliance.Results: Neither adherence nor competence were related to treatment outcomes in clinician or patient rated PTSD symptom severity. Higher alliance was associated with a lower symptom severity at 12 months posttreatment in both clinician and patient rated PTSD symptoms.Conclusions: In this study of young adults with PTSD, who were treated with D-CPT by well -trained therapists, therapeutic adherence and competence were not related to treatment outcome. This might be explained by a lack of range in therapist adherence and competence. Therapeutic alliance had a positive effect on PTSD symptom severity.
