摘要：Abstract Background Despite robust empirical support for the efficacy of trauma-focused treatments, the dissemination proves difficult, especially in relation to patients with comorbid psychosis. Many therapists endorse negative beliefs about the credibility, burden, and harm of such treatment. Objective This feasibility study explores the impact of specialized training on therapists’ beliefs about trauma-focused treatment within a randomized controlled trial. Method Therapist-rated (n=16) credibility, expected burden, and harm expectancies of trauma-focused treatment were assessed at baseline, post-theoretical training, post-technical training, post-supervised practical training, and at 2-year follow-up. Credibility and burden beliefs of therapists concerning the treatment of every specific patient in the trial were also assessed. Results Over time, therapist-rated credibility of trauma-focused treatment showed a significant increase, whereas therapists’ expected burden and harm expectancies decreased significantly. In treating posttraumatic stress disorder (PTSD) in patients with psychotic disorders (n=79), pre-treatment symptom severity was not associated with therapist-rated credibility or expected burden of that specific treatment. Treatment outcome had no influence on patient-specific credibility or burden expectancies of therapists. Conclusions These findings support the notion that specialized training, including practical training with supervision, has long-term positive effects on therapists’ credibility, burden, and harm beliefs concerning trauma-focused treatment. Highlights of the article Specialized training improved therapists’ credibility, burden, and harm beliefs. Patients’ symptom severity and treatment outcome did not affect these beliefs. Replication of our findings in larger cohorts with a control group is warranted.
