Abstract
Background: The complexity of posttraumatic stress disorder (PTSD) symptoms related to childhood abuse (CA) present challenges for effective psychotherapeutic treatment. Consequently, there is great interest in the long-term effectiveness of psychological treatments for this population.Objective: This study aims to investigate the long-term outcomes of Dialectical Behaviour Therapy for PTSD (DBT-PTSD) and Cognitive Processing Therapy (CPT) 9 months after treatment termination.Method: This is a long-term analysis from a randomised-controlled trial of DBT-PTSD versus CPT (registration number DRKS00005578). Initially, 193 individuals with CA-related PTSD were randomly allocated to receive either DBT-PTSD (n = 98) or CPT (n = 95). The primary outcome the Clinician-administered PTSD-Scale for DSM-5 (CAPS-5) was administred at baseline, treatment completion (15 months post-randomization) and at the 9-month follow-up. Secondary outcomes included self-reported PTSD severity (PCL-5), dissociation (DSS), severity of borderline symptoms (BSL-23), and psychosocial functioning (GAF).Results: No significant changes were observed in the primary (CAPS) and all other outcomes from post-intervention to 9-months follow-up in both the DBT-PTSD (CAPS: Mpost = 15.60, Mfollow-up = 14.93) and CPT group (CAPS: Mpost = 18.80, Mfollow-up = 17.41). Between-group analyses at 9-months follow-up were significantly in favour of DBT-PTSD compared to CPT with small to medium effect sizes on all outcomes ranging from d = 0.35 on the CAPS to d = 0.57 on the BSL-23 and GAF.Conclusions: Our results indicate that treatment effects of psychotherapy addressing complex presentations of PTSD persist 9 months after treatment termination. In addition, the superiority of DBT-PTSD as compared to CPT found at treatment termination, was confirmed at 9-months follow-up.Trial registration: German Clinical Trials Register identifier: DRKS00005578..
期刊介绍：
The European Journal of Psychotraumatology (EJPT) is a peer-reviewed open access interdisciplinary journal owned by the European Society of Traumatic Stress Studies (ESTSS). The European Journal of Psychotraumatology (EJPT) aims to engage scholars, clinicians and researchers in the vital issues of how to understand, prevent and treat the consequences of stress and trauma, including but not limited to, posttraumatic stress disorder (PTSD), depressive disorders, substance abuse, burnout, and neurobiological or physical consequences, using the latest research or clinical experience in these areas. The journal shares ESTSS’ mission to advance and disseminate scientific knowledge about traumatic stress. Papers may address individual events, repeated or chronic (complex) trauma, large scale disasters, or violence. Being open access, the European Journal of Psychotraumatology is also evidence of ESTSS’ stand on free accessibility of research publications to a wider community via the web. The European Journal of Psychotraumatology seeks to attract contributions from academics and practitioners from diverse professional backgrounds, including, but not restricted to, those in mental health, social sciences, and health and welfare services. Contributions from outside Europe are welcome. The journal welcomes original basic and clinical research articles that consolidate and expand the theoretical and professional basis of the field of traumatic stress; Review articles including meta-analyses; short communications presenting new ideas or early-stage promising research; study protocols that describe proposed or ongoing research; case reports examining a single individual or event in a real‑life context; clinical practice papers sharing experience from the clinic; letters to the Editor debating articles already published in the Journal; inaugural Lectures; conference abstracts and book reviews. Both quantitative and qualitative research is welcome.
