Show morePhysical and sexual abuse during childhood can have long lasting consequences such as posttraumatic stress disorder (PTSD). Prolonged Exposure (PE) is an established and effective guideline treatment for PTSD. Nevertheless, a considerable number of patients drop out from treatment or do not (completely) recover from PTSD during PE. It has been suggested that patients with PTSD resulting from childhood abuse are specifically at risk for suboptimal treatment outcomes. We carried out a randomized controlled trial with 149 patients with childhood abuse-related PTSD comparing PE with two innovations: intensified PE (iPE) and skills training in affective and interpersonal regulation followed by PE (STAIR+PE). We found that all treatments were safe and resulted in large improvements in PTSD symptoms. iPE and STAIR+PE did not improve treatment outcomes of PE, although iPE led to faster symptom improvements. Not all patients benefitted from the allocated treatment, but we found no contra-indications for the treatments. We found that a combination of patient characteristics was predictive of a larger effect size of PTSD symptom improvement in PE and iPE or STAIR+PE. We conclude that the three forms of exposure therapy were effective treatments for patients with childhood abuse-related PTSD. Show less

Show moreBackground: One reason for the inclusion of Complex Posttraumatic Stress Disorder (CPTSD) in the 11th revision of the International Classification of Diseases (ICD-11) was its suspected relevance for treatment indications. We investigated whether CPTSD predicted and moderated treatment outcomes of Prolonged Exposure (PE), intensified PE (iPE) and Skills Training in Affective and Interpersonal Regulation followed by PE (STAIR + PE). We expected that CPTSD would predict worse treatment outcomes across treatments. Secondly, we expected that CPTSD would lead to better treatment effect in STAIR + PE compared to PE and iPE.Methods: We analyzed 149 patients with childhood-abuse related PTSD from a randomized clinical trial. CPTSD diagnosis and symptom severity were measured with the International Trauma Questionnaire. The main outcome was change in clinician-assessed PTSD symptoms. Assessments took place at baseline, week 4, week 8, week 16 (post-treatment) and at a 6-and 12-month follow-up. Analyses were based on an intention-to-treat sample using mixed effect models.Results: More than half (54 %) of the patients met criteria for CPTSD at baseline. CPTSD was related to more severe PTSD symptoms and higher comorbidity at baseline. CPTSD neither predicted nor moderated treatment outcome. Limitations: Inclusion was limited to patients with PTSD related to childhood abuse. Replication is needed in different samples.Conclusions: CPTSD is associated with more severe PTSD and with higher comorbidity. CPTSD did not predict treatment outcome and did not indicate differential treatment outcome of STAIR + PE compared to PE and iPE. Show less
