Trauma-focused and personality disorder treatment for posttraumatic stress disorder and comorbid cluster C personality disorder: a randomized clinical trial. Eur J Psychotraumatol 2024; 15:2382652. [PMID: 39087734 PMCID: PMC11295684 DOI: 10.1080/20008066.2024.2382652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 03/15/2024] [Accepted: 07/12/2024] [Indexed: 08/02/2024] Open
Abstract
Background: Posttraumatic stress disorder (PTSD) is associated with high rates of cluster C personality disorders (PD), which may negatively affect PTSD treatment. It is unknown whether concurrent treatment for PTSD and comorbid PD leads to superior treatment effects, compared to standard trauma-focused treatment.Objective: The objective was to test the efficacy of adding personality disorder treatment (group schema therapy; GST) to individual trauma-focused treatment (imagery rescripting; ImRs).Method: A two-arm randomized clinical trial (1:1 allocation ratio) was conducted between 2018 and 2023 at two sites of a mental health institution in the Netherlands. Raters were blind to treatment allocation. Adult outpatients with PTSD and comorbid cluster C personality disorders were randomized to receive either ImRs (12-18 sessions) or ImRs + GST (12-18 ImRs + 52-58 GST). The main outcome was PTSD severity one year after start of treatment measured with the Clinician-Administered PTSD Scale for DSM-5.Results: Of 130 patients (mean [SD] age = 40.6 [11.2], 110 [85%] females), 66 were assigned to ImRs and 64 to ImRs + GST. At 12 months, there were large decreases in PTSD severity (dImRs = 2.42, 95%CI = 1.97-2.87; dImRs + GST = 2.44, 95%CI = 1.99-2.90), but there was no significant difference between conditions (d = 0.02, 95%CI = -0.33-0.36, p = .944). Reductions in personality disorder symptoms and all other secondary outcomes were observed in both conditions. There were no significant differences between conditions on any of the secondary outcomes at 12 months.Conclusion: The more intensive concurrent trauma-focused and personality disorder treatment (ImRs + GST) was not superior to trauma-focused treatment alone (ImRs) for patients with PTSD and comorbid CPD. This suggests that trauma-focused treatment is the preferred primary treatment in patients presenting with both internalizing personality disorder and PTSD, reserving the stepping up to more intensive psychotherapy aimed at the personality disorder as a second line of treatment.Trial registration: ClinicalTrials.gov identifier: NCT03833531.

Eur J Psychotraumatol 2024; 15:2367815. [PMID: 38957149 PMCID: PMC11225629 DOI: 10.1080/20008066.2024.2367815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 05/29/2024] [Indexed: 07/04/2024] Open
Abstract
Background: Comorbidity between posttraumatic stress disorder (PTSD) and borderline personality disorder (BPD) is surrounded by diagnostic controversy and although various effective treatments exist, dropout and nonresponse are high.Objective: By estimating the network structure of comorbid PTSD and BPD symptoms, the current study illustrates how the network perspective offers tools to tackle these challenges.Method: The sample comprised of 154 patients with a PTSD diagnosis and BPD symptoms, assessed by clinician-administered interviews. A regularised partial correlation network was estimated using the GLASSO algorithm in R. Central symptoms and bridge symptoms were identified. The reliability and accuracy of network parameters were determined through bootstrapping analyses.Results: PTSD and BPD symptoms largely clustered into separate communities. Intrusive memories, physiological cue reactivity and loss of interest were the most central symptoms, whereas amnesia and suicidal behaviour were least central.Conclusions: Present findings suggest that PTSD and BPD are two distinct, albeit weakly connected disorders. Treatment of the most central symptoms could lead to an overall deactivation of the network, while isolated symptoms would need more specific attention during therapy. Further experimental, longitudinal research is needed to confirm these hypotheses.Trial registration: ClinicalTrials.gov identifier: NCT03833453.

van den End A, Beekman ATF, Dekker J, Thomaes K. Self-rated personality disorder symptoms do not predict treatment outcome for posttraumatic stress disorder in routine clinical care. Clin Psychol Psychother 2023; 30:1338-1348. [PMID: 37985013 DOI: 10.1002/cpp.2933] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/28/2023] [Accepted: 10/30/2023] [Indexed: 11/22/2023]
Abstract
OBJECTIVE To test the hypothesis that self-rated personality disorder (PD) symptoms are a significant and clinically relevant predictor of treatment outcomes in a naturalistic treatment setting specialized in trauma-focused treatment using a single-group pretest-posttest design. METHOD Treatment-seeking patients reporting clinical levels of posttraumatic stress disorder (PTSD) symptoms filled out questionnaires at intake and after treatment. The primary outcome was change in PTSD severity after treatment, measured by the PTSD Checklist for DSM-5 (PCL-5). PD symptoms were measured with the Structured Clinical Interview for DSM-5 Screening Personality Questionnaire (SCID-5-SPQ). Secondary outcomes were general mental health problems, treatment response, number of sessions and dropout. RESULTS N = 1174 patients (59% female, baseline PCL-5 score M [SD] = 53.0 [10.8]) were included for the primary analysis. Regression analysis revealed that PD symptoms explained 0.4% of variance in PTSD symptom change (p = .066). After controlling for baseline PTSD symptoms, PD symptoms explained 0.0% of variance (p = .311). The fully adjusted model including baseline PTSD symptom severity, age, gender, cumulative exposure to potentially traumatic experiences, PD symptoms, and number of sessions together explained 5% of the observed variance in PTSD symptom change. Baseline PTSD severity was the only significant predictor and negatively predicted outcome. Sensitivity analyses with imputed data from N = 2694 cases yielded comparable results. Finally, secondary analyses showed that PD symptoms did not predict significant or clinically relevant changes in treatment response status, general mental health problems, dropout rates or number of sessions. CONCLUSION The findings provide no evidence that self-rated PD symptoms predict treatment outcomes for patients suffering from clinical levels of PTSD symptoms in a naturalistic treatment setting specializing in trauma-focused treatment. Self-report screening for these symptoms to inform clinicians about expected effects of PTSD treatment is not supported by the evidence.

Neural correlates of treatment effect and prediction of treatment outcome in patients with PTSD and comorbid personality disorder: study design. Borderline Personal Disord Emot Dysregul 2021; 8:13. [PMID: 33947471 PMCID: PMC8097786 DOI: 10.1186/s40479-021-00156-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 04/09/2021] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND Neural alterations related to treatment outcome in patients with both post-traumatic stress disorder (PTSD) and comorbid personality disorder are unknown. Here we describe the protocol for a neuroimaging study of treatment of patients with PTSD and comorbid borderline (BPD) or cluster C (CPD) personality disorder traits. Our specific aims are to 1) investigate treatment-induced neural alterations, 2) predict treatment outcome using structural and functional magnetic resonance imaging (MRI) and 3) study neural alterations associated with BPD and CPD in PTSD patients. We hypothesize that 1) all treatment conditions are associated with normalization of limbic and prefrontal brain activity and hyperconnectivity in resting-state brain networks, with additional normalization of task-related activation in emotion regulation brain areas in the patients who receive trauma-focused therapy and personality disorder treatment; 2) Baseline task-related activation, together with structural brain measures and clinical variables predict treatment outcome; 3) dysfunction in task-related activation and resting-state connectivity of emotion regulation areas is comparable in PTSD patients with BPD or CPD, with a hypoconnected central executive network in patients with PTSD+BPD. METHODS We aim to include pre- and post-treatment 3 T-MRI scans in 40 patients with PTSD and (sub) clinical comorbid BPD or CPD. With an expected attrition rate of 50%, at least 80 patients will be scanned before treatment. MRI scans for 30 matched healthy controls will additionally be acquired. Patients with PTSD and BPD were randomized to either EMDR-only or EMDR combined with Dialectical Behaviour Therapy. Patients with PTSD and CPD were randomized to Imaginary Rescripting (ImRs) or to ImRs combined with Schema Focused Therapy. The scan protocol consists of a T1-weighted structural scan, resting state fMRI, task-based fMRI during an emotional face task and multi-shell diffusion weighted images. For data analysis, multivariate mixed-models, regression analyses and machine learning models will be used. DISCUSSION This study is one of the first to use neuroimaging measures to predict and better understand treatment response in patients with PTSD and comorbid personality disorders. A heterogeneous, naturalistic sample will be included, ensuring generalizability to a broad group of treatment seeking PTSD patients. TRIAL REGISTRATION Clinical Trials, NCT03833453 & NCT03833531 .
