标题：Treatment compliance and effectiveness in complex PTSD patients with co-morbid personality disorder undergoing stabilizing cognitive behavioral group treatment: a preliminary study
摘要：Background: In the empirical and clinical literature, complex posttraumatic stress disorder (PTSD) and personality disorders (PDs) are suggested to be predictive of drop-out or reduced treatment effectiveness in trauma-focused PTSD treatment.Objective: In this study, we aimed to investigate if personality characteristics would predict treatment compliance and effectiveness in stabilizing complex PTSD treatment. Method: In a randomized controlled trial on a 20-week stabilizing group cognitive behavioral treatment (CBT) for child-abuse-related complex PTSD, we included 71 patients of whom 38 were randomized to a psycho-educational and cognitive behavioral stabilizing group treatment. We compared the patients with few PD symptoms (adaptive) (N=14) with the non-adaptive patients (N=24) as revealed by a cluster analysis.Results: We found that non-adaptive patients compared to the adaptive patients showed very low drop-out rates. Both non-adaptive patients, classified with highly different personality profiles ‘‘withdrawn’’ and ‘‘aggressive,’’ were equally compliant. With regard to symptom reduction, we found no significant differences between subtypes. Post-hoc, patients with a PD showed lower drop-out rates and higher effect sizes in terms of complex PTSD severity, especially on domains that affect regulation and interpersonal problems.Conclusion: Contrary to our expectations, these preliminary findings indicate that this treatment is well tolerated by patients with a variety of personality pathology. Larger sample sizes are needed to study effectiveness for subgroups of complex PTSD patients.Keywords: Personality disorders; treatment outcome; child abuse; posttraumatic stress disorder; cognitive behavioral treatment; complex PTSD; dissociative subtype(Published: 6 November 2013)For the abstract or full text in other languages, please see Supplementary files in the column to the right (under Article Tools)Citation: European Journal of Psychotraumatology 2013, 4: 21171 - http://dx.doi.org/10.3402/ejpt.v4i0.21171
