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: M post  = 15.60, M follow-up   = 14.93) and CPT group (CAPS: M post  = 18.80, M follow-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.

Background: Literature on the association between therapist adherence and treatment success in the treatment of post-traumatic stress disorder (PTSD) is scarce, and the results are mixed. Objective: To examine the relationship between therapist adherence to dialectical behaviour therapy for PTSD (DBT-PTSD) and cognitive processing therapy (CPT) on treatment outcome in women with PTSD and emotion regulation difficulties after interpersonal childhood abuse. Method: Videotaped therapy sessions from 160 female participants of a large randomized controlled trial [Bohus, M., Kleindienst, N., Hahn, C., Müller-Engelmann, M., Ludäscher, P., Steil, R., Fydrich, T., Kuehner, C., Resick, P. A., Stiglmayr, C., Schmahl, C., & Priebe, K. (2020). Dialectical behavior therapy for posttraumatic stress disorder (DBT-PTSD) compared with cognitive processing therapy (CPT) in complex presentations of PTSD in women survivors of childhood abuse. JAMA Psychiatry , 77 (12), 1235. jamapsychiatry.2020.2148] were rated. Adherence to CPT and DBT-PTSD was assessed using two specifically developed rating scales. Results: Higher therapist adherence was associated with a greater reduction of clinician-rated PTSD symptom severity. This effect was more pronounced in the CPT group than in the DBT-PTSD group. Adherence was also related to a greater reduction of self-rated PTSD symptoms, borderline symptoms, and dissociation intensity. Conclusion: Our results indicate that higher therapist adherence can lead to better treatment outcomes in PTSD treatments, especially in CPT.

Background: The assessment of therapeutic adherence and competence is essential to understand mechanisms that contribute to treatment outcome. Nevertheless, their assessment is often neglected in psychotherapy research., Aims/objective: To develop an adherence and a treatment-specific competence rating scale for Dialectical Behaviour Therapy for Posttraumatic Stress Disorder (DBT-PTSD), and to examine their psychometric properties. Global cognitive behavioural therapeutic competence and disorder-specific therapeutic competence were assessed using already existing scales to confirm their psychometric properties in our sample of patients with PTSD and emotion regulation difficulties., Method: Two rating scales were developed using an inductive procedure. 155 videotaped therapy sessions from a multicenter randomised controlled trial were rated by trained raters using these scales, 40 randomly chosen videotapes involving eleven therapists and fourteen patients were doubly rated by two raters., Results: Both the adherence scale (Patient-level ICC = .98; α s  = .65; α p   = .75) and the treatment-specific competence scale (Patient-level ICC = .98; α s  = .78; α p   = .82) for DBT-PTSD showed excellent interrater - and good reliability on the patient level. Content validity, including relevance and appropriateness of all items, was confirmed by experts in DBT-PTSD for the new treatment-specific competence scale., Conclusion: Our results indicate that both scales are reliable instruments. They will be useful to examine possible effects of adherence and treatment-specific competence on DBT-PTSD treatment outcome., Competing Interests: The authors receive honoraria for supervision, workshops and presentations on PTSD treatments, including DBT-PTSD. The authors declare that they have no further conflicts of interest., (© 2022 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.)

Objective: About half of individuals seeking treatment for borderline personality disorder (BPD) present with co-occurring posttraumatic stress disorder (PTSD). However, therapies that have been proven efficacious for simultaneously treating the full spectrum of core symptoms in patients with a dual diagnosis of BPD + PTSD are lacking., Method: This is a subgroup analysis from a randomized controlled trial (registration number DRKS00005578) which compared the efficacy of two treatment programs, dialectical behavior therapy for PTSD (DBT-PTSD) versus cognitive processing therapy (CPT). Specifically, the present analysis was carried out in 93 women with a dual diagnosis of BPD + PTSD (Diagnostic and Statistical Manual for Mental Disorders; DSM-5). Outcome evaluations included the Clinician-Administered PTSD Scale, the Borderline Symptom List, and validated scales assessing dissociation, depression, and global functioning. The primary analysis was based on the intent-to-treat population, using mixed models., Results: Both PTSD and BPD symptoms significantly decreased in both treatment groups. For PTSD symptoms, pre-post effect sizes were d = 1.20, 95% confidence interval (CI): [0.80-1.58] in the DBT-PTSD group and d = 0.90, 95% CI: [0.57-1.22] in the CPT group; for BPD symptoms, they were d = 1.17, 95% CI: [0.77-1.55], and d = 0.50, 95% CI: [0.20-0.79], respectively. Between-group comparisons significantly favored DBT-PTSD for improvement in symptoms of PTSD, BPD, and dissociation. Between-group differences regarding depression and global functioning were not significant., Conclusion: Both DBT-PTSD and CPT emerged as promising treatment options for simultaneously addressing the full spectrum of core symptoms in patients diagnosed with BPD + PTSD. Differential efficacy was in favor of DBT-PTSD as participants randomized to the DBT-PTSD arm improved more with respect to both their BPD and PTSD symptoms.

Importance: Childhood abuse significantly increases the risk of developing posttraumatic stress disorder (PTSD), often accompanied by symptoms of borderline personality disorder (BPD) and other co-occurring mental disorders. Despite the high prevalence, systematic evaluations of evidence-based treatments for PTSD after childhood abuse are sparse., Objective: To compare the efficacy of dialectical behavior therapy for PTSD (DBT-PTSD), a new, specifically designed, phase-based treatment program, against that of cognitive processing therapy (CPT), one of the best empirically supported treatments for PTSD., Design, Setting, and Participants: From January 2014 to October 2016, women who sought treatment were included in a multicenter randomized clinical trial with blinded outcome assessments at 3 German university outpatient clinics. The participants were prospectively observed for 15 months. Women with childhood abuse-associated PTSD who additionally met 3 or more DSM-5 criteria for BPD, including affective instability, were included. Data analysis took place from October 2018 to December 2019., Interventions: Participants received equal dosages and frequencies of DBT-PTSD or CPT, up to 45 individual sessions within 1 year and 3 additional sessions during the following 3 months., Main Outcomes and Measures: The predefined primary outcome was the course of the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) score from randomization to month 15. Intent-to-treat analyses based on dimensional CAPS-5 scores were complemented by categorical outcome measures assessing symptomatic remission, reliable improvement, and reliable recovery., Results: Of 955 consecutive individuals assessed for eligibility, 193 were randomized (DBT-PTSD, 98; CPT, 95; mean [SD] age, 36.3 [11.1] years) and included in the intent-to-treat analyses. Analysis revealed significantly improved CAPS-5 scores in both groups (effect sizes: DBT-PTSD: d, 1.35; CPT: d, 0.98) and a small but statistically significant superiority of DBT-PTSD (group difference: 4.82 [95% CI, 0.67-8.96]; P = .02; d, 0.33). Compared with the CPT group, participants in the DBT-PTSD group were less likely to drop out early (37 [39.0%] vs 25 [25.5%]; P = .046) and had higher rates of symptomatic remission (35 [40.7%] vs 52 [58.4%]; P = .02), reliable improvement (53 [55.8%] vs 73 [74.5%]; P = .006), and reliable recovery (34 [38.6%] vs 52 [57.1%]; P = .01)., Conclusions and Relevance: These findings support the efficacy of DBT-PTSD and CPT in the treatment of women with childhood abuse-associated complex PTSD. Results pertaining to the primary outcomes favored DBT-PTSD. The study shows that even severe childhood abuse-associated PTSD with emotion dysregulation can be treated efficaciously., Trial Registration: German Clinical Trials Register: DRKS00005578.

Dialectical behavior therapy for posttraumatic stress disorder (DBT-PTSD) is a trauma-focused therapy shown to reduce core PTSD symptoms, such as intrusions, hyperarousal, and avoidance. Preliminary data indicate effects on elevated trauma-related emotions (e.g., guilt and shame) and possibly radical acceptance of the traumatic event. However, it is unclear if improvements in these variables are significant after controlling for changes in core PTSD symptoms and to what extent nonclinical levels are obtained. In the current study, 42 individuals who met criteria for PTSD after childhood abuse and were participating in a 3-month residential DBT-PTSD program were evaluated at the start of the exposure phase of DBT-PTSD and the end of treatment; a nonclinical sample with a history of childhood abuse was the reference group. Multivariate analyses of variance and multivariate analyses of covariance controlling for change in core PTSD symptoms were used to evaluate changes in several elevated trauma-related emotions (fear, anger, guilt, shame, disgust, sadness, and helplessness) and in radical acceptance. In a repeated measures multivariate analyses of variance, both elevated trauma-related emotions and radical acceptance significantly improved during DBT-PTSD, λ = 0.34, p < .001; η 2 = .56; t(40) = -5.66, p < .001, SMD = 0.88, even after controlling for changes in PTSD symptoms, λ = 0.35, p < .001, η 2 = .65; Λ = 0.86, p = .018, η 2 = .14, respectively. Posttreatment, 31.0% (for acceptance) to 76.2% (for guilt) of participants showed nonclinical levels of the investigated outcomes, suggesting that both trauma-related emotions and radical acceptance changed after the 3-month residential DBT-PTSD program., (© 2019 International Society for Traumatic Stress Studies.)
