Clinical phenomenology of childhood abuse-related complex PTSD in a population of female patients: patterns of personality disturbance

The Relationship Between Dissociation and Complex Post-Traumatic Stress Disorder: A Scoping Review

Complex post-traumatic stress disorder (CPTSD) has recently been recognized as an official psychiatric diagnosis in ICD-11, after years of research and advocacy in the field. It has been suggested that dissociative symptoms are a major feature of CPTSD. This scoping review aimed to summarize the existing knowledge base on the relationship between dissociation and CPTSD, and to identify relevant research gaps. We searched the two largest and most widely used academic databases (i.e., the Web of Science and Scopus databases) and the ProQuest database and identified original studies published in English relevant to our research questions, namely: (1) Would CPTSD be associated with dissociative symptoms? 2) How common are dissociative symptoms among people with CPTSD? (3) What are the correlates of dissociative symptoms among people with CPTSD? In all, 26 studies were included. We found 10 studies which reported that people with CPTSD scored significantly higher on a dissociation measure than those without CPTSD, and 11 studies reported a positive correlation between CPTSD symptoms and psychoform/somatoform dissociation scores. While very few studies reported the prevalence and correlates of dissociative symptoms among people with CPTSD, there may be a considerable subgroup of people with CPTSD who have clinically significant levels of dissociative symptoms (e.g., 28.6-76.9%). Dissociation may also be associated with other comorbidities (e.g., DSM-IV Axis II features, shame, somatic symptoms) in people with CPTSD. We recommend that more studies are needed to investigate the prevalence of dissociative symptoms among people with CPTSD and examine how these symptoms are associated with other comorbid conditions and clinical needs in this vulnerable group.

Cluster B versus Cluster C Personality Disorders: A Comparison of Comorbidity, Suicidality, Traumatization and Global Functioning

A general clinical assumption states that cluster B personality disorders (PDs) represent a more severe form of PD than cluster C PDs. Consequently, most PD research is centered on cluster B PDs (especially borderline PD). Yet, prevalence ratings of cluster C PDs exceed those of cluster B PDs. In this explorative, cross-sectional study, we compared cluster B and C PD patients (N = 94) on a wide range of clinically-relevant severity measures, including comorbidity, suicidality, (childhood) traumatization and global functioning. Results showed that, although cluster B PD patients suffered more often from substance use disorders and lifetime suicide attempts, no difference could be established between groups for all other severity measures, including trauma variables. In our study, we additionally included a group of combined cluster B and C PDs, who were largely similar to both other groups. Although our study is insufficiently powered to claim a significant non-difference, these findings emphasize that high rates of comorbidity, suicidality, childhood traumatization and functional impairment apply to both cluster B and C patients. As such, our findings encourage more research into cluster C PDs, ultimately leading to more evidence-based treatments for this prevalent patient group. In addition, the high level of traumatization across groups calls for a routine trauma screening, especially since PD treatment may benefit from concurrent trauma treatment.

The Role and Clinical Correlates of Complex Post-traumatic Stress Disorder in People With Psychosis

Traumatic experiences and post-traumatic stress are highly prevalent in people with psychosis, increasing symptom burden, decreasing quality of life and moderating treatment response. A range of post-traumatic sequelae have been found to mediate the relationship between trauma and psychotic experiences, including the "traditional" symptoms of post-traumatic stress disorder (PTSD). The International Classification of Diseases-11th Edition recognizes a more complex post-traumatic presentation, complex PTSD (cPTSD), which captures both the characteristic symptoms of PTSD alongside more pervasive post-traumatic sequelae known as 'disturbances in self-organization' (DSOs). The prevalence and impact of cPTSD and DSOs in psychosis remains to be explored. In the first study of this kind, 144 participants with psychosis recruited from North West United Kingdom mental health services completed measures assessing trauma, PTSD and cPTSD symptoms and symptoms of psychosis. Forty-percent of the sample met criteria for cPTSD, compared to 10% who met diagnostic criteria for PTSD. PTSD and DSOs mediated the relationship between trauma and positive symptoms, controlling for dataset membership. Both PTSD and DSOs mediated the relationship between trauma and affective symptoms but did not explain a significant proportion of variance in negative symptoms. Cognitive and excitative symptoms of psychosis did not correlate with trauma, PTSD or DSO scores. These findings indicate the possible value of adjunct therapies to manage cPTSD symptoms in people with psychosis, pending replication in larger epidemiological samples and longitudinal studies.

The Co-Occurrence of Trauma Related Disorder and Borderline Personality Disorder: AQ Study on a Clinical Sample of Patients Seeking Psychotherapy Treatment

The nature of the relationship between borderline personality disorder (borderline PD), post-traumatic stress disorder (PTSD) and complex PTSD remains controversial. In this study we attempted to investigate the association between traumatic events and borderline PD and the co-occurrence of complex PTSD, PTSD and borderline PD. Finally, we tested the association between complex PTSD and PTSD diagnoses and other DSM-5 Section II personality disorders. In a sample of 416 patients, we administered the International Trauma Questionnaire (ITQ) to evaluate the PTSD/complex PTSD diagnoses and the Structured Clinical Interview for DSM-5 Personality Disorders (SCID-5-PD) and the Personality Diagnostic Questionnaire- 4+ (PDQ-4+) to assess borderline PD and other PDs. One hundred-twenty-three participants reported experiencing one or more traumatic events. Our findings show that the presence of adverse events does not represent a risk factor for borderline PD assessed using both SCID-5-PD and PDQ4+. A co-occurrence of borderline PD diagnoses and complex PTSD/PTSD diagnoses has not been observed. We found a significant association only between complex PTSD and schizoid personality disorder assessed using PDQ4+. Our findings suggest relevant clinical implications for the development of effective treatment for complex PTSD, PTSD and borderline PD.

Evidence for two different ICD-11 posttraumatic stress disorders in a community sample of adolescents and young adults

For the 11th revision of the International classification of diseases, a general category of posttraumatic stress disorders has been proposed with two distinct sibling disorders: posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD). General population data are examined on evidence for these two disorders. Data were drawn from a 10-year prospective longitudinal, epidemiological study with a representative community sample (N = 3021, 14-24 years at baseline) in Germany. Mixture modelling on latent classes was conducted in a subset of all reported episodes with exposure to interpersonal traumas. Associations between class membership, symptom criteria, and other mental disorders were investigated. Four distinctly interpretable latent classes were found. Class 1 episodes (N = 181) typically included core PTSD symptoms associated with strong impairment (OR 11.68; 95 % CI 4.54-30.05). 18.3 % of these episodes matched the criteria of ICD-11 PTSD. Class 2 episodes (N = 78) had a high probability of PTSD core symptoms and disturbances in self-organization and were associated with strong impairment (OR 38.47; 95 % CI 15.77-93.86). Half of them (49.4 %) matched the proposed ICD-11 criteria of CPTSD. Class 3 (N = 79) was typically characterized by episodes with disturbances in self-organization but a low probability of PTSD core symptoms and impairment. Class 4 (N = 633) was related to a relatively low probability of symptom reports. Membership in class 2 was associated with lower educational attainment, a lower social class, and more other mental disorders. Findings support the ICD-11 proposal to differentiate between PTSD and CPTSD. Further studies should extend exploration to other types of traumatic events in samples covering the full age range.

Early traumatized inpatients high in psychoform and somatoform dissociation: characteristics and treatment response

This study examined the clinical relevance of differences in psychoform and somatoform dissociative symptoms in 55 early traumatized inpatients. The high psychoform and somatoform dissociative group (n = 18), somatoform dissociative group (n = 22), and nondissociative group (n = 15) did not differ on abuse severity, depressive symptoms, interpersonal problems, Axis I or II comorbidity, or deterioration rates. Compared to the other 2 groups, the highly dissociative group was characterized by younger age, living alone, higher levels of posttraumatic and general distress, more frequent reports of suicidality, self-mutilation, eating problems, and less favorable treatment response. The results highlight the clinical relevance of using dissociation measures for identifying subgroups of patients with severe psychopathology who may be more treatment resistant.

Complex PTSD, affect dysregulation, and borderline personality disorder

Complex PTSD (cPTSD) was formulated to include, in addition to the core PTSD symptoms, dysregulation in three psychobiological areas: (1) emotion processing, (2) self-organization (including bodily integrity), and (3) relational security. The overlap of diagnostic criteria for cPTSD and borderline personality disorder (BPD) raises questions about the scientific integrity and clinical utility of the cPTSD construct/diagnosis, as well as opportunities to achieve an increasingly nuanced understanding of the role of psychological trauma in BPD. We review clinical and scientific findings regarding comorbidity, clinical phenomenology and neurobiology of BPD, PTSD, and cPTSD, and the role of traumatic victimization (in general and specific to primary caregivers), dissociation, and affect dysregulation. Findings suggest that BPD may involve heterogeneity related to psychological trauma that includes, but extends beyond, comorbidity with PTSD and potentially involves childhood victimization-related dissociation and affect dysregulation consistent with cPTSD. Although BPD and cPTSD overlap substantially, it is unwarranted to conceptualize cPTSD either as a replacement for BPD, or simply as a sub-type of BPD. We conclude with implications for clinical practice and scientific research based on a better differentiated view of cPTSD, BPD and PTSD.

Treatment compliance and effectiveness in complex PTSD patients with co-morbid personality disorder undergoing stabilizing cognitive behavioral group treatment: a preliminary study

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.

CONCLUSIONS

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.
