Evidence of complex posttraumatic stress disorder (CPTSD) across populations with prolonged trauma of varying interpersonal intensity and ages of exposure

Reconceptualizing complex posttraumatic stress disorder: A predictive processing framework for mechanisms and intervention

In this article, we introduce a framework for interpreting Complex Posttraumatic Stress Disorder (C-PTSD) through predictive processing, a neuroscience concept explaining the brain's interpretation and prediction of sensory information. While closely related to PTSD, C-PTSD encompasses additional symptom clusters marked by disturbances in self-organization (DSO), such as negative self-concept, affect dysregulation, and relational difficulties, typically resulting from prolonged traumatic stressors. Our model leverages advances in computational psychiatry and neuroscience, offering a mechanistic explanation for these symptoms by illustrating how prolonged trauma disrupts the brain's predictive processing. Specifically, altered predictive mechanisms contribute to C-PTSD's symptomatology, focusing on DSO: (1) Negative self-concept emerges from maladaptive priors that bias perception towards self-criticism, misaligning expected and actual interoceptive states; (2) Misalignment between predicted and actual interoceptive signals leads to affect dysregulation, with sensitivity to bodily cues; and (3) Relationship challenges arise from skewed social prediction errors, fostering mistrust and withdrawal. This precision-focused approach sheds light on the dynamics underpinning C-PTSD and highlights potential intervention targets aimed at recalibrating the predictive processing system.

[Effects of complex trauma disorder on the workplace: a scoping review]

BACKGROUND

The "International Classification of Diseases 11th Revision" (ICD-11) introduces complex post-traumatic stress disorder (CPTSD) as a separate diagnosis to account for the effects that persistent or repetitive trauma can have. In CPTSD, disorders of self-organization are added to the core symptoms of PTSD. It can be assumed that those affected are impaired in their professional lives as a result. The aim of this paper is to provide an overview of the effects of CPTSD on work-related functioning and to present possible consequences for therapeutic and rehabilitative treatment.

METHOD

A scoping review with a literature search in the MEDLINE, APA PsycArticles, and APA PsycInfo databases was conducted in February 2024.

RESULTS

Of 2378 studies on KPTBS, five studies were included, of which only three dealt more specifically with the impact on the world of work. Those affected appear to have a poorer prognosis for maintaining their ability to work and are therefore to be regarded as a socio-medical risk group with regard to long-term maintenance of participation in working life.

DISCUSSION

The current state of research on the effects of the CPTSD symptom complex on the world of work is surprisingly limited. In comparison, the results indicate that CPTSD has a greater negative impact on the ability to function in the world of work than PTSD and other mental disorders. It is still unclear which psychopathological mechanisms mediate the connection. Only basic findings on the psychopathology of CPTSD are available. Treatment approaches that address the disorders of self-organization in addition to PTSD symptoms appear necessary.

Unmasking the Struggle: A Scoping Review Exploring Post-Traumatic Stress Symptoms in Caregivers of Individuals with Neurodevelopmental, Psychiatric and Neurocognitive Disorders

The impact of caregiving on caregivers' mental health is typically considered within the caregiver stress and burden literature; however, more recently, research has investigated the experience of post-traumatic stress symptoms (PTSS) in caregivers. As an emerging area of research, it is timely to conduct a scoping review to map the existing literature in relation to PTSS among adult caregivers of children and adults with neurodevelopmental disorders (NDD), neurocognitive disorders, and psychiatric disorders. The scoping review was conducted using Preferred Reporting Items of Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines and Arksey and O'Malley's five-stage methodology framework. Published and unpublished gray literature between 2005 and 2022 was included in the scoping review. Nine thousand one hundred and twenty-five studies were originally identified for screening and 22 studies were selected for inclusion in the final review. Trauma and PTSS experienced by NDD caregivers were related to news breaking, NDD diagnosis, and behavioral issues, whereas caregivers of individuals with psychosis reported aggression and violence as traumatic events. Studies showed that up to half of caregivers reported PTSS, although no conclusions could be drawn about prevalence rates. A wide variety of tools measuring PTSS were used across the 22 studies. Many symptoms of PTSS were reported by caregivers, and cognitive appraisals were associated with PTSS in caregivers. The findings highlight the importance of recognizing the impact of trauma in caregiver mental health and the potential value of using traumatic stress frameworks with these populations. Research should be expanded to establish prevalence rates and to examine the long-term impact of trauma on caregiving as caregivers and care recipients age.

Prevalence of Complex Post-Traumatic Stress Disorder in Serving Military and Veteran Populations: A Systematic Review

Serving military personnel and veterans are known to be at elevated risk of post-traumatic stress disorder (PTSD), and some veterans have been shown to respond poorly to current standard treatments. Evidence so far suggests that according to the 11th edition of the International Classification of Diseases and Related Health Problems guidelines, complex PTSD (CPTSD) may be of higher prevalence in the general population than PTSD. The aim of the study was to investigate the prevalence of CPTSD compared to PTSD in serving and ex-serving military populations. A systematic review was conducted with the search criteria set to peer-reviewed English language journal articles, focusing on serving military or veteran populations, reporting on the prevalence of CPTSD, not restricted by year. Four comprehensive databases (Psycinfo, Pubmed, CINAHL, and Embase) were searched. Of the 297 identified articles, 16 primary studies were eligible for inclusion. The review was registered in the PROSPERO database (CRD42023416458), and results were reported based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Of the 16 studies, 13 demonstrated higher prevalence of CPTSD than PTSD. Studies were predominantly veteran focused. Prevalence of CPTSD ranged from 5% to 80.63%, while prevalence of PTSD ranged from 3.8% to 42.37%. There was high heterogeneity in study populations, preventing meta-analysis. This is the first systematic review to assess the prevalence of CPTSD in serving military and veteran populations, with the findings demonstrating a higher rate of CPTSD compared to PTSD. It is hoped that the review will assist clinicians and military and veteran health services with appropriate assessment, diagnosis, and intervention for those affected by CPTSD, as well as PTSD.

Prevalence, comorbidities, and factors associated with prolonged grief disorder, posttraumatic stress disorder and complex posttraumatic stress disorder in refugees: a systematic review

BACKGROUND

The number of refugees worldwide is at an all-time high with many being exposed to potentially traumatic events and the loss of loved ones. The 11th revision of the International Statistical Classification of Diseases and Related Health Problems now includes prolonged grief disorder and complex posttraumatic stress disorder and revised criteria for posttraumatic stress disorder. An overview of these stress-related disorders among people who have become refugees is therefore needed. Consequently, we conducted a systematic review to determine prevalence rates, comorbidities, and associated factors for each of the disorders.

METHOD

We systematically searched PubMed, Web of Science, and PsycArticles to identify studies that reported prevalence rates, predictors or associated factors, and/or comorbid mental disorders for either (1) prolonged grief disorder, (2) posttraumatic stress disorder, or (3) complex posttraumatic stress disorder among refugees. The selection process followed the PRISMA guidelines.

RESULTS

A total of 36 studies met the inclusion criteria. Most of the studies were of high quality. There was substantial variation in prevalence rates by disorder, with prolonged grief ranging from 6 to 54%, posttraumatic stress disorder ranging from 0.4 to 80%, and complex posttraumatic stress disorder ranging from 3 to 74.6%. Pooled prevalence for posttraumatic stress disorder was estimated at 29.8% in treatment seeking samples and 9.92% in population samples. For complex posttraumatic stress disorder, it was estimated at 57.4% in treatment seeking samples and 7.8% in population samples. Posttraumatic stress disorder was among the most frequent comorbidities for prolonged grief disorder while depressive symptoms were the most frequently occurring co-morbidity across all three disorders. Sociodemographic variables, trauma exposure, and loss characteristics were associated with higher symptom severity. Postmigration living difficulties played an important role in prolonged grief and complex posttraumatic stress disorder.

CONCLUSION

The review revealed substantial differences in prevalence rates between the three studied disorders but underscored a very high prevalence of ICD-11 stress-related disorders among refugees. The identified associated factors point to subgroups that may be particularly at risk and establishes a foundational basis for targeted interventions and potential policy changes. Future research should incorporate longitudinal investigations and emphasize culturally sensitive assessments.

Psychotic and Somatic Symptoms Are Frequent in Refugees With Posttraumatic Stress Disorder: A Narrative Review

OBJECTIVE

In 2021, 89.3 million refugees were vulnerable to posttraumatic stress disorder (PTSD) after exposure to multiple and repeated traumatic experiences. The recent war in Ukraine provoked 7 million refugees to flee their homes. Specific clinical presentations of PTSD in refugee populations may not be familiar to most physicians. The goal of this review is to describe the diagnosis and specific clinical features of PTSD in refugees.

METHODS

This narrative review of 263 articles explores 3 PTSD diagnoses that are frequently described in refugee populations and that have been observed in our clinical practices: complex PTSD, PTSD with psychotic symptoms, and PTSD with somatic symptoms.

RESULTS

While complex PTSD does not seem to be related to individuals' culture and origin, the other 2 diagnoses have been specifically described in refugee populations. PTSD with somatic manifestations appears to be the most frequently described and commonly acknowledged form in refugee populations, whereas PTSD with psychotic symptoms remains more controversial due to its clinical variability and association with comorbid disorders.

CONCLUSIONS

The difficulty of identifying PTSD with psychotic symptoms and PTSD with somatic symptoms in refugee populations may lead to misdiagnosis and explain the moderate effectiveness of care delivered to these populations. Appropriate diagnosis is essential to provide optimal psychiatric care to refugee populations.

Trauma Isn't One Size Fits All: How Online Support Communities Point to Different Diagnostic Criteria for C-PTSD and PTSD

Reddit has provided rich data on mental health discourse. The present study uses 40,335 online posts from Reddit communities to investigate how language can contribute to the understanding of PTSD and C-PTSD. The results showed distinct language patterns in the use of first-person pronouns, cognitive processing, and emotion words, suggesting that they are separate disorders with different effects on survivors. Further, while some social media studies have differentiated submissions and comments, few have investigated the language changes between these contexts. Post-hoc results showed a clear distinction between two contexts across several linguistic markers. Discussion and future directions are explored.

Cross-cultural validity and psychometric properties of the International Trauma Questionnaire in a clinical refugee sample

Background: The ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD diagnoses have been examined in several studies using the International Trauma Questionnaire (ITQ). The cross-cultural validity of the ITQ has not previously been studied using item responses theory methods focused on the issue of equal item functioning and thus comparability of scores across language groups.Objective: To investigate the cross-cultural validity of the ITQ scales considering specifically local independence of items and differential item functioning (DIF) in a cross-cultural sample of refugees.Method: Data from 490 treatment-seeking refugees were included, covering Danish, Arabic, and Bosnian languages and different levels of interpreter-assisted administration. Rasch and graphical log-linear Rasch models were used.Results: There was strong local dependence among items from the same symptom clusters in the PTSD and disorders in self-organization (DSO) scales, except between affective dysregulation items. Weak local dependence was discovered between an item from the affective dysregulation cluster and an item from the disturbed relationship cluster. There was no evidence of DIF related to language or interpreter assistance. There was evidence of DIF for two PTSD items relative to gender and time since the traumatic event. The targeting of the scales to the study population was not optimal. Reliability varied from 0.55 to 0.78 for subgroups.Conclusions: The PTSD and the DSO scales have stable psychometric properties across the Danish, Arabic, and Bosnian language versions and different levels of assisted administration. Scores are comparable across these groups. However, DIF relative to gender and time since trauma introduces considerable measurement bias. DIF-adjusted summed scale scores or estimated person parameters should be used to avoid measurement bias. Future research should investigate whether scales including more and/or alternative items that require higher levels of PTSD and DSO to be endorsed will improve targeting and measurement precision for refugee populations.

War-related stressors and ICD-11 (complex) post-traumatic stress disorders in Ukrainian students living in Kyiv during the Russian-Ukrainian war

We estimated the prevalence of war-related stressors (Harvard Trauma Questionnaire-R), risk of ICD-11 posttraumatic stress disorder (PTSD), and complex posttraumatic stress disorder (CPTSD; International Trauma Questionnaire-R) in N = 563 Ukrainian students living in Kyiv, an active war zone between December 2022 and January 2023. Among trauma survivors (n = 381), we used multinomial logistic regression to examine whether different war-related traumatic events and cumulative trauma increased risk for ICD-11-PTSD and CPTSD after controlling for other traumatic events, age, and gender. Nine of ten Ukrainian students (91.5%) reported at least one war-related stressor, one of five (20.8%) reported four or more stressors. War-related combat situations were reported most frequently (59.5%), followed by forced separation from family members (54.5%), lack of shelter (53.3%), and murder or violent death of a family member or friend (15.6%). Rates for probable ICD-11 PTSD and CPTSD were 12.4% and 11.2%, respectively. Sexual violence and cumulative trauma exposure significantly increased the risk of CPTSD compared to other traumatic events. The high proportions of ICD-11-PTSD and CPTSD underscore the psychological burden of Ukrainian students living in an active war zone and the need for trauma-focused interventions for war-affected populations.

Migrants' mental health recovery in Italian reception facilities

BACKGROUND

Forced migration leaves deep marks on the psychological well-being of migrants, with post-traumatic stress disorder (PTSD) and other psychological conditions being prevalent among them. While research has clarified the extent to which pre-migration trauma is a predictor of mental health outcomes, the role of post-migration stressors in the settlement environment are yet to be fully characterized.

METHODS

We monitored mental health of a cohort of 100 asylum-seekers during their 14-day COVID-19-related quarantine in reception facilities in Rome, Italy, through the administration of six questionnaires (a demographic survey, the WHO-5 well-being index, the Primary Care PTSD Screen for Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5), the Harvard Trauma Questionnaire, the Trauma and Loss Spectrum-Self Report, and the LiMEs-Italian version). Through the combination of statistical analysis and supervised learning, we studied the impact of the first contact with the reception system on asylum-seekers' mental health and sought for possible risk and shielding factors for PTSD.

RESULTS

We find that sheltering in refugee centers has a positive impact on migrants' mental health; asylum-seekers with PTSD reported more traumatic events and personality characteristics related to loss and trauma; life events are predictors of PTSD in asylum-seekers.

CONCLUSIONS

We identify past traumatic experiences as predictors of PTSD, and establish the positive role the immediate post-migration environment can play on migrants' psychological well-being. We recommend for host countries to implement reception models that provide effective protection and integration of asylum-seekers, similar to those in the Italian system.

The prevalence, latent structure and psychosocial and cognitive correlates of complex post-traumatic stress disorder in an adolescent community sample

Complex PTSD has received growing attention in recent years. However, the validity, prevalence and risk factors of this diagnosis remain unclear. This study examined PTSD presentations in adolescents using diagnostic criteria and latent class analysis (LCA). It then explored the role of demographics factors, trauma history factors, psychopathology factors and cognitive factors in predicting different PTSD presentations. A cross-sectional data comprising self-report measures of 342 community adolescents (12-15 years) were collected and analysed. 2.3 %, 5.6 % and 10 % of adolescents met the criteria for PTSD, CPTSD and disturbances in self-organisation (DSO) respectively. A three-class model (healthy class, CPTSD class and DSO class) were generated from LCA. Adolescents with CPTSD were most likely to be female and endorsed the most overall trauma types, interpersonal trauma types, depression, anxiety and maladaptive cognitive processes, followed by adolescents with DSO and subsequently healthy adolescents. CPTSD appeared to be a more common presentation than PTSD among community adolescents. The relatively high prevalence of DSO is noteworthy and suggests that DSO is not necessarily accompanied by PTSD. Given the strong associations between CPTSD and cognitive processes implicated in PTSD, CPTSD as a construct might be conceptually similar to PTSD.

Questions arising from the application of the ICD-11 diagnoses of complex post traumatic stress disorder and personality disorder

There is an overlap between the International Classification of Diseases for Mortality and Morbidity Statistics- 11th Revision (ICD-11) diagnoses of complex post-traumatic stress disorder (CPTSD) and personality disorder. When the latter is comorbid with post-traumatic stress disorder (PTSD), this may allow for a false positive CPTSD diagnosis. This fact has both clinical implications and throws into relief theoretical questions about the ontology of trauma and personality disorder-related pathology. These questions are presented as a call for further research.

Are migrants diagnosed with a trauma-related disorder at risk of premature mortality? A register-based cohort study in Denmark

Background

Mental illness is common among refugees displaced by conflict and war. While evidence points to the relatively good health in terms of longevity of migrants resettled in the destination country, less is known about the mortality of the most vulnerable migrants with a trauma-related diagnosis alone and those with an additional comorbid psychotic disorder. This study aimed to provide an overview of the number and mortality of foreign-born individuals diagnosed with Post-Traumatic Stress Disorder or Enduring Personality Change after a Catastrophic Event (PTSD/EPCACE), a psychotic disorder or both.

Methods

A nationwide register-based cohort study, including residents in Denmark, followed from 1 January 1995 to 31 December 2016. The exposure was PTSD/EPCACE and psychotic disorders as well as region of origin. Relative all-cause mortality was estimated using Cox proportional hazards regression models and calculated for migrants with one or both groups of disorders compared to those from the same region without the disorder.

Results

During the study period, 6,580,000 individuals (50.4% women) were included in the cohort. Of these 1,249,654 (50.5% women) died during follow-up. For men and women from the former Yugoslavia, the Middle East and Northern Africa, a PTSD/EPCACE diagnosis alone or with comorbid psychotic disorder was not associated with increased mortality after adjusting for region of origin. A psychotic disorder alone, however, was associated with an increased mortality rate.

Conclusion

Despite the severity of many refugees' traumatic experiences, a diagnosis of a trauma-related psychiatric disorder did not appear to increase the mortality rates.

Risk factors, comorbidity and social impairment of ICD-11 PTSD and complex PTSD in Danish treatment-seeking military veterans

PURPOSE

While a number of studies have investigated risk factors and comorbidities of ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) in various trauma exposed samples, few studies have been conducted in military samples. Existing studies with military samples have included rather small samples. The aim of the present study was to identify risk factors and comorbidities of ICD-11 PTSD and CPTSD in a large sample of previously deployed, treatment-seeking soldiers and veterans.

METHODS

Previously deployed, treatment-seeking Danish soldiers and veterans (N = 599), recruited from the Military Psychology Department of the Danish Defense, completed the International Trauma Questionnaire (ITQ), as well as questionnaires of common mental health difficulties, trauma exposure, functioning and demographics. Multivariate multinomial logistic regression analysis explored differences in self-reported exposure to adversity and health outcomes between those meeting ICD-11 criteria for probable PTSD, CPTSD and no trauma disorder.

RESULTS

A total of 13.0% met probable ICD-11 criteria for PTSD and 31.4% for CPTSD. Risk factors for CPTSD (compared to those with no trauma disorder) included exposure to warfare or combat, longer duration since the traumatic event and being single. Those with CPTSD were more likely than those with PTSD or no trauma disorder to endorse symptoms of depression, anxiety, stress, use of psychotropic medication, and suicide attempts.

CONCLUSION

CPTSD is a more common and debilitating condition compared to PTSD in treatment-seeking soldiers and veterans. Further research should focus on testing existing and novel interventions for CPTSD in the military.

Heterogeneity In Women's Trauma Histories: Impact On Substance Use Disorder Severity

Trauma and substance use disorders (SUDs) frequently co-occur, especially in women. Previous studies have attempted to determine if individual differences in trauma histories could be meaningfully categorized but few studies have focused solely on women, especially those reporting substance use problems. A total of 130 women (M age = 30.7, SD = 7.9) self reporting past-year substance use problems completed comprehensive measures assessing lifetime exposure to a variety of traumatic events as well as substance use patterns and severity. Using latent class analysis, three classes emerged, a Low Lifetime Interpersonal Trauma class (40%, n = 52), a Moderate Lifetime Interpersonal Trauma class (23.8%, n = 31) and a High Lifetime Interpersonal Trauma class (36.2%, n = 47). Groups did not vary on daily/almost daily use of different types of substances and polysubstance use frequency but were significantly different on SUD severity, with the Moderate and the High Lifetime Interpersonal Trauma classes reporting severe SUD severity in comparison to moderate severity for the Low Interpersonal Trauma class. The findings of the current study indicate that women experiencing substance use problems should receive SUD treatment in a trauma-informed manner but that not all may require integrated trauma and substance use interventions.

Pathophysiological aspects of complex PTSD - a neurobiological account in comparison to classic posttraumatic stress disorder and borderline personality disorder

Despite a great diagnostic overlap, complex posttraumatic stress disorder (CPTSD) has been recognised by the ICD-11 as a new, discrete entity and recent empirical evidence points towards a distinction from simple posttraumatic stress disorder (PTSD) and borderline personality disorder (BPD). The development and maintenance of these disorders is sustained by neurobiological alterations and studies using functional magnetic resonance imaging (fMRI) may further contribute to a clear differentiation of CPTSD, PTSD and BPD. However, there are no existing fMRI studies directly comparing CPTSD, PTSD and BPD. In addition to a summarization of diagnostic differences and similarities, the current review aims to provide a qualitative comparison of neuroimaging findings on affective, attentional and memory processing in CPTSD, PTSD and BPD. Our narrative review alludes to an imbalance in limbic-frontal brain networks, which may be partially trans-diagnostically linked to the degree of trauma symptoms and their expression. Thus, CPTSD, PTSD and BPD may underlie a continuum where similar brain regions are involved but the direction of activation may constitute its distinct symptom expression. The neuronal alterations across these disorders may conceivably be better understood along a symptom-based continuum underlying CPTSD, PTSD and BPD. Further research is needed to amend for the heterogeneity in experimental paradigms and sample criteria.

Adult Attachment as a Mediator of the Link Between Interpersonal Trauma and International Classification of Diseases (ICD)-11 Complex Posttraumatic Stress Disorder Symptoms Among College Men and Women

Previous research indicates that insecure attachment patterns are associated with interpersonal trauma and posttraumatic symptomatology, and that they mediate various trauma-related symptoms. However, no study to date has examined whether these patterns mediate the link between interpersonal trauma and the newly recognized diagnostic features of complex posttraumatic stress disorder (CPTSD), as published by the World Health Organization (2019) in the 11th version of the International Classification of Diseases (ICD-11). Mediators of CPTSD are important to identify because they can provide a deeper understanding of the condition's etiology. Moreover, if amenable to clinical intervention, they can be targeted to improve treatment effectiveness. The purpose of the present study was to formally test our hypothesis that two underlying dimensions of adult attachment insecurity (i.e., attachment anxiety and avoidance) would mediate the link between interpersonal trauma and ICD-11 CPTSD symptoms. Participants were a culturally diverse sample of 169 college men and women. They completed a modified version of the Life Events Checklist (LEC-5), the revised Experiences in Close Relationships (ECR-R) scale, and the International Trauma Questionnaire (ITQ). Results of path analysis partially supported our hypothesis, indicating that attachment anxiety, but not avoidance, partially mediated the link between interpersonal trauma and PTSD and DSO ("Disturbances in Self-Organization") features of CPTSD. Although longitudinal research is needed, findings suggest that attachment anxiety may contribute to the development and maintenance of CPTSD symptoms following interpersonal trauma. Clinical interventions that help individuals rework and integrate representations of attachment that involve a fear of not being able to access adequate care and protection, and a negative view of self may be particularly useful in ameliorating the symptoms of CPTSD.

Exploring the links between various traumatic experiences and ICD-11 PTSD and Complex PTSD: A cross-sectional study

Background

The 11th revision of the International Classification of Diseases (ICD-11) included two distinct trauma-related diagnoses—Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD). The initial diagnostic factor for both disorders is exposure to a traumatic event. This study aimed to explore whether exposure to different traumatic experiences distinguish risk for PTSD and CPTSD.

Methods

The study sample comprised 158 trauma-exposed participants, M(SD)_age = 33.61(9.73). The Life Events Checklist-Revised (LEC-R) was used to evaluate trauma exposure, and the International Trauma Questionnaire (ITQ) was used to assess risk for ICD-11 PTSD and CPTSD. Multinomial logistic regression was used to determine traumatic events as predictors of risk for PTSD and CPTSD.

Results

Analysis revealed that sexual abuse experienced in childhood or adulthood was associated with both PTSD and CPTSD. History of other unwanted sexual experiences and childhood physical abuse predicted CPTSD compared to PTSD, whereas exposure to natural disasters predicted PTSD compared to CPTSD.

Conclusions

The results showed that experiences of certain traumatic events, such as sexual trauma, childhood physical abuse or natural disasters, might help distinguish risk for PTSD and CPTSD. Nevertheless, future studies on specific aspects of trauma exposure are necessary.

Prevalence, correlates, and the mitigation of ICD-11 CPTSD among homeless adults: The role of self-compassion

BACKGROUND

In 2018, Complex Post-Traumatic Stress Disorder (CPTSD) was accepted into the International Classification of Diseases, edition 11 (ICD-11) to capture symptoms associated with exposure to chronic, inescapable trauma. Thereafter, the disorder's links with interpersonal trauma have been established.

OBJECTIVE

Within a sample of homeless adults in Ireland, the (1) prevalence of ICD-11 disorders specifically associated with stress; Post Traumatic Stress Disorder (PTSD) and CPTSD, (2) nature of interpersonal trauma exposure, self-identified index events, and their association with the diagnostic criteria of CPTSD, and (3) relationship between cumulative interpersonal trauma exposure and CPTSD via self-compassion were examined.

PARTICIPANTS AND SETTING

Adults using homeless services (N = 56) completed self-report measures of socio-demographics, trauma-history, PSTD, CPTSD, and self-compassion.

METHODS

The data were analysed using chi-squared and mediation analyses (via PROCESS).

RESULTS

CPTSD was highly prevalent (33.9%) among the sample, but PTSD was not (3.6%). Emotional neglect was the most prevalent interpersonal trauma and the most common index event. Only lifetime sexual abuse (from someone other than a parent or guardian) was associated with CPTSD diagnostic status (χ² = 3.94, (1), p = .047). When adjusted for gender, relationship status, and living situation, self-compassion mediated the relationship between cumulative interpersonal trauma exposure and CPTSD severity (B = 1.30, SE = 0.50, 95% CI = [0.43-2.35]).

CONCLUSION

Findings support the relevance of CPTSD to understanding psychopathology in homeless adults and the potential role of self-compassion in interventions. Further, they open debate on the nature of events that are considered traumatic - subjectively and in psychiatric canon.

The validity of ICD-11 PTSD and complex PTSD in North Korean defectors using the International Trauma Questionnaire

Background: The International Trauma Questionnaire (ITQ) is a self-report assessment focused on the core features of Post-Traumatic Stress Disorder (PTSD) and complex Post-Traumatic Stress Disorder (CPTSD). It is consistent with the organizing principles of the 11th revision to the WHO's International Classification of Diseases (ICD-11). Since the 1990s, the number of North Korean defectors (NKD) entering South Korea to escape human rights violations has been increasing rapidly, with 33,815 NKD settled by 2021. The South Korean government faces an important challenge in supporting NKD to successfully adapt and settle in South Korean society. NKD experience various traumatic events during the process of defecting and repatriation. Therefore, it is essential to understand the psychological disorders of NKD, especially PTSD and CPTSD. Objective: This study aimed to test the validity of the ITQ assessment and explore the differences in symptoms and quality of life between PTSD and CPTSD. Method: The study sample comprised 503 trauma-exposed NKD. Confirmatory factor analysis (CFA) and latent class analysis (LCA) were used to evaluate the validity of ITQ. One-way analysis of variances and post-hoc analyses revealed the difference in the Depression and Somatic Symptoms Scale (DSSS) and WHOQOL-BREF results among PTSD and CPTSD symptom LCA classes. Results: The CFA and LCA results supported the ICD-11 conceptualization of PTSD and CPTSD in NKD. The CFA results confirmed that both the first- and second-order models were statistically fit, but for community-dwelling NKD the first-order model had better model fit than the second-order model. The LCA findings revealed a four-class model with 'PTSD', 'CPTSD', 'DSO', and 'low symptom' classes. Compared to the PTSD class, CPTSD class had higher levels of depression and somatic symptoms and a lower quality of life. Conclusion: This study provided evidence that ITQ is a valid tool to assess PTSD or CPTSD in community-dwelling NKD.

Prevalence of mental disorders in refugees and asylum seekers: a systematic review and meta-analysis

BACKGROUND

Studies have identified high rates of mental disorders in refugees, but most used self-report measures of psychiatric symptoms. In this study, we examined the percentages of adult refugees and asylum seekers meeting diagnostic criteria for major depressive disorder (MDD), post-traumatic stress disorder, bipolar disorder (BPD), and psychosis.

METHODS

A systematic literature search in three databases was conducted. We included studies examining the prevalence of MDD, post-traumatic stress disorder, BPD, and psychosis in adult refugees according to a clinical diagnosis. To estimate the pooled prevalence rates, we performed a meta-analysis using the Meta-prop package in Stata (PROSPERO: CRD42018111778).

RESULTS

We identified 7048 records and 40 studies (11 053 participants) were included. The estimated pooled prevalence rates were 32% (95% CI 26-39%; I ² = 99%) for MDD, 31% (95% CI 25-38%; I ² = 99.5%) for post-traumatic stress disorder, 5% (95% CI 2-9%; I ² = 97.7%) for BPD, and 1% (95% CI 1-2%; I ² = 0.00%) for psychosis. Subgroup analyses showed significantly higher prevalence rates of MDD in studies conducted in low-middle income countries (47%; 95% CI 38-57%, p = 0.001) than high-income countries studies (28%; 95% CI 22-33%), and in studies which used the Mini-International Neuropsychiatric Interview (37%; 95% CI 28-46% p = 0.05) compared to other diagnostic interviews (26%; 95% CI 20-33%). Studies among convenience samples reported significant (p = 0.001) higher prevalence rates of MDD (35%; 95% CI 23-46%) and PTSD (34%; 95% CI 22-47%) than studies among probability-based samples (MDD: 30%; 95% CI 21-39%; PTSD: 28%; 95% 19-37%).

CONCLUSIONS

This meta-analysis has shown a markedly high prevalence of mental disorders among refugees. Our results underline the devastating effects of war and violence, and the necessity to provide mental health intervention to address mental disorders among refugees. The results should be cautiously interpreted due to the high heterogeneity.

Exploring complex-PTSD comorbidity in trauma-exposed Northern Ireland veterans

BACKGROUND

Complex posttraumatic stress disorder (CPTSD) describes the results of complex, prolonged, and/or inescapable trauma, and is typified by avoidance, re-experiencing, sense of threat, affect dysregulation, negative self-concept, and interpersonal disturbances. Additionally, CPTSD is highly comorbid with other common psychopathologies.

OBJECTIVES

A study was conducted in a trauma-exposed UK Armed Forces Veteran population resident in Northern Ireland (N = 638, NI) to determine the prevalence of CPTSD and comorbid associations.

METHODS

Data from the Northern Ireland Veterans Health and Wellbeing Study (NIVHWS), including self-report data describing traumatic stress, depression, anxiety, and suicidality, were used in a latent class analysis to identify distinct profiles of symptomology in the sample, and in a multinomial logistic regression to identify comorbidities associated with class membership.

RESULTS

Three distinct classes emerged: a low endorsement 'baseline' class (36%), a 'Moderate Symptomatic' class (27%), and a high endorsement 'Probable CPTSD' class (37%). Both the Moderate Symptomatic and CPTSD classes were predicted by cumulative trauma exposure. Depression was highly comorbid (OR = 23.06 in CPTSD), as was anxiety (OR = 22.05 in CPTSD) and suicidal ideation (OR = 4.32 in CPTSD), with suicidal attempt associated with the CPTSD class (OR = 2.51).

CONCLUSIONS

Cases of probable CPTSD were more prevalent than cases of probable posttraumatic stress disorder (PTSD) without Difficulties in Self-Organisation (DSO) symptoms in a UK Armed Forces veteran sample, were associated with repeated/cumulative trauma, and were highly comorbid across a range of psychopathologies. Findings validate previous literature on CPTSD and indicate considerable distress and thus need for support in UK Armed Forces veterans resident in NI.

The latent structure of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD in a general population sample from USA: A factor mixture modelling approach

The validity of ICD-11 Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD), as measured by the International Trauma Questionnaire (ITQ; Cloitre et al., 2018) has been supported in many factor analytic and mixture modelling studies. There is, however, a paucity of research investigating the latent structure of the ITQ using factor mixture modelling (FMM). FMM was applied to data collected from a nationally representative sample of U.S. adults (N = 1834). FMM results demonstrated strong support for a two-factor second-order model with four qualitatively distinct latent classes: a 'PTSD class', a 'CPTSD class', a 'DSO' (Disturbances in Self-Organisation) class and a 'low symptoms class'. Sexual abuse increased likelihood of membership to the 'CPTSD' (OR = 3.22) and physical abuse decreased likelihood of membership to the 'PTSD' (OR=0.51). Trauma exposure in adulthood predicted 'PTSD' and 'CPTSD' class membership. The 'CPTSD class' was characterised by higher levels of psychopathological co-morbidities and poorer psychological wellbeing compared to all other classes. Results provide additional support for the validity of PTSD and CPTSD as measured by the ITQ.

Complex post-traumatic stress disorder and post-migration living difficulties in traumatised refugees and asylum seekers: the role of language acquisition and barriers

Background

Numerous traumatic experiences and post-migration living difficulties (PMLDs) increase the risk of developing symptoms of complex post-traumatic stress disorder (CPTSD) among Afghan refugees and asylum seekers, living in Austria. Research has repeatedly associated higher levels of CPTSD with higher levels of PMLDs. Summarizing PMLDs into empirically derived factors might facilitate a further understanding of their interaction with symptom presentation within distinct clusters of CPTSD.

Objective

The current study aimed to investigate homogeneous subgroups of ICD-11 CPTSD and their association with demographic variables, traumatic experiences, and empirically derived factors of PMLDs.

Method

Within a randomized controlled trail (RCT) CPTSD, PMLDs, and traumatic experiences were assessed in a sample of 93 treatment-seeking Afghan refugees and asylum seekers through a fully structured face-to-face and interpreter-assisted interview using the ITQ, the PMLDC, and a trauma checklist. Underlying clusters of CPTSD, superior factors of PMLDs, and their associations were investigated.

Results

In total, 19.4% of the sample met the diagnostic criteria for PTSD and 49.5% for CPTSD. We identified a 2-cluster solution consisting of two distinct subgroups as best fitting: (1) a CPTSD cluster and (2) a PTSD cluster. The multitude of PMLDs was summarized into four superior factors. CPTSD cluster membership was associated with childhood potentially traumatic experience types, and one of four PMLD factors, namely 'language acquisition & barriers'.

Conclusions

The results suggest that not PMLDs in general, but rather specific types of PMLDs, are associated with CPTSD. An assumed bidirectional relationship between these PMLD factors and CPTSD symptoms might lead to a downward spiral of increasing distress, and could be considered in treatment strategies.

Risk factors for complex posttraumatic stress disorder in UK police

Background

Police officers are frequently exposed to distressing and dangerous situations, increasing their risk of posttraumatic stress disorder (PTSD) and complex PTSD (C-PTSD). Research examining C-PTSD in police officers is sparse, particularly examination of the occupational risk factors for trauma symptoms.

Aims

This study aimed to examine the prevalence and risk factors for PTSD and C-PTSD in UK police officers.

Methods

A cross-sectional study was conducted using psychological health surveillance data from the UK National Police Wellbeing Service. Police officers were either from high-risk areas of work or had been referred for screening by occupational health practitioners regarding psychological distress. The primary outcome for this study was a positive screening of either PTSD or C-PTSD, measured using the International Trauma Questionnaire. A range of occupational, clinical and lifestyle factors was examined to establish their role as potential risk factors for PTSD and C-PTSD.

Results

In total, 2444 UK police officers were included, with 89% from high-risk areas of work. A prevalence of 3% for PTSD and 2% for C-PTSD was found in police officers from high-risk areas of work. Higher work stress and lower manager support were found to increase the odds of C-PTSD but not PTSD. Higher personal trauma history increased the risk for PTSD and C-PTSD equally.

Conclusions

Work-related occupational factors increased the odds of PTSD and C-PTSD in police officers, which could be important risk factors for trauma symptoms within police officers. Efforts should be made to improve the working environment of police officers to help improve their psychological well-being.

Exploring complex PTSD in patients visiting a psychiatric outpatient clinic in Kathmandu, Nepal

Decades of research on trauma patients have shown that a post-traumatic stress disorder (PTSD) diagnosis does not always cover the full spectrum of symptoms after severe trauma. Complex PTSD (CPTSD) was recently introduced in the International Classification of Diseases 11th Revision. There have been no published studies on CPTSD in the South Asian region to date. The objective of this study was to evaluate CPTSD in a sample of trauma patients in Nepal. We also examined quality of life (QOL) and mental health comorbidities and their association with CPTSD caseness. One hundred patients with a history of trauma who visited the outpatient psychiatry clinic at a hospital in Kathmandu from 2017 to 2018 were assessed. The Composite International Diagnostic Interview Version 2.1 was used to evaluate PTSD, major depressive disorder, and generalized anxiety disorder (GAD). Disturbance of self-organization symptoms from the Structured Interview for Disorders of Extreme Stress (SIDES) together with the PTSD diagnosis was used to confirm CPTSD caseness. The World Health Organization (WHO) QOL Scale Brief Version (WHOQOL-BREF) was used to assess QOL in four domains. Among the 83 patients who had PTSD, 42 also had CPTSD. CPTSD was significantly associated with major depressive disorder, GAD, female gender, and lower QOL in all four domains. CPTSD was prevalent among these patients. Having CPTSD was significantly associated with worse outcomes in terms of QOL and comorbid mental disorders, even with similar trauma. There is a need to explore CPTSD symptoms and to address trauma patients with CPTSD in this region.

Factor structure and symptom classes of ICD-11 complex posttraumatic stress disorder in a South Korean general population sample with adverse childhood experiences

BACKGROUND

Adverse childhood experiences (ACE) are known as risk factors for poor adulthood mental health, including ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD). While many studies focused on the association of ACE and CPTSD, examining variant symptom patterns related to ACE is lacking.

OBJECTIVE

This study aimed to identify the factorial validity of the ICD-11 CPTSD and its distinctive symptom classes in Korean adults with ACE from a representative community sample and examine the risk factors and clinical symptoms that distinguish the CPTSD symptom classes.

METHODS

We conducted a cross-sectional retrospective study with the International Trauma Questionnaire data from 800 adult general population with ACE histories. A confirmatory factor analysis, latent class analysis, analysis of variance and multinomial logistic regression were conducted.

RESULTS

Results of confirmatory factor analysis supported a six-factor correlation model, while a two-factor higher-order model with PTSD and disturbances in self-organization (DSO) as correlated constructs also showed excellent fit. A latent class analysis identified six classes, including a distinctive ICD-11 CPTSD and PTSD, additionally a DSO with sense of threat, a DSO, an emotion dysregulation, and a low symptom class, showing distinguished features in ACE patterns, lifetime trauma, depression, somatization, panic disorder, and subtypes of dissociation.

CONCLUSIONS

The factorial and discriminant validity of ICD-11 CPTSD for Korean ACE survivors were confirmed. Recognizing the pervasive impact of patterns of ACEs and lifetime trauma would be helpful in access to and delivery of appropriate mental health services. Variation in symptom presentations of CPTSD and the role of dissociation should be of concern, that it may bring complicated life outcomes to people with ACEs.

Validation of ICD-11 PTSD and DSO using the International Trauma Questionnaire in five clinical samples recruited in Denmark

Background: The 11^th version of the International Classification of Diseases (ICD-11) revised the diagnosis of Posttraumatic Stress Disorder (PTSD) and introduced Complex PTSD as a sibling disorder to PTSD. As the Danish Health Authorities will implement the ICD-11 in 2022, it is more relevant than ever to introduce a measure that enables the identification of ICD-11 PTSD and CPTSD. Objective: The primary aim of the present study was to test the construct validity of the ICD-11 conceptualization of PTSD and DSO in five clinical samples using translated versions of the International Trauma Questionnaire (ITQ). Method: Data from existing studies of adult survivors of sexual abuse (n = 385), women in shelters (n = 147), psychiatric outpatients endorsing an ICD-10 diagnosis of PTSD (n = 111), a heterogenous sample of psychiatric outpatients (n = 178) and refugees and torture survivors (n = 385) was used for the current study. Confirmatory factor analyses were conducted to test the internal structure of the ITQ, and regression models were conducted to test the convergent and discriminant validity of the factor solutions for each sample. Results: Findings supported the ICD-11 formulation of PTSD and disorders in self-organization (DSO) as a representation of the latent structure of the ITQ across five Danish clinical samples. Uniquely for women in shelters, however, the model displayed an unacceptable fit. A revised operationalization of re-experiencing proved a better fit when 'recurrent nightmares' was exchanged with symptoms of intense emotional reactions to reminders of the trauma for women in shelter as well as ICD-10 PTSD psychiatric outpatients. Conclusion: This study supports the use of a Danish translated version of the ITQ to assess symptoms of ICD-11 PTSD and DSO for the introduction of ICD-11 in 2022. Future research is needed to further explore the operationalization of re-experiencing across different trauma exposed populations.

Prevalence and treatment implications of ICD-11 complex PTSD in Australian treatment-seeking current and ex-serving military members

Background: Despite growing support for the distinction between posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as separate diagnoses within the ICD-11 psychiatric taxonomy, the prevalence and treatment implications of CPTSD among current and ex-serving military members have not been established. Objective: The study aims were to a) establish the prevalence of provisional ICD-11 CPTSD diagnosis relative to PTSD in an Australian sample of treatment-seeking current and ex-serving military members, and b) examine the implications of CPTSD diagnosis for intake profile and treatment response. Methods: The study analysed data collected routinely from Australian-accredited treatment programmes for military-related PTSD. Participants were 480 current and ex-serving military members in this programmes who received a provisional ICD-11 diagnosis of PTSD or CPTSD at intake using proxy measures. Measures of PTSD symptoms, disturbances in self-organisation, psychological distress, mental health and social relationships were considered at treatment intake, discharge, and 3-month follow-up. Results: Among participants with a provisional ICD-11 diagnosis, 78.2% were classified as having CPTSD, while 21.8% were classified as having PTSD. When compared to ICD-11 PTSD, participants with CPTSD reported greater symptom severity and psychological distress at intake, and lower scores on relationship and mental health dimensions of the quality of life measure. These relative differences persisted at each post-treatment assessment. Decreases in PTSD symptoms between intake and discharge were similar across PTSD (d _RM  = -0.81) and CPTSD (d _RM  = -0.76) groups, and there were no significant post-treatment differences between groups when controlling for initial scores. Conclusions: CPTSD is common among treatment-seeking current and ex-serving military members, and is associated with initially higher levels of psychiatric severity, which persist over time. Participants with CPTSD were equally responsive to PTSD treatment; however, the tendency for those with CPTSD to remain highly symptomatic post-treatment suggests additional treatment components should be considered.

The relationship between childhood adversities and complex posttraumatic stress symptoms: a multiple mediation model

Background: There is a growing research literature on complex posttraumatic stress disorder (CPTSD), yet studies that focused on Chinese populations are still limited. Accumulating evidence showed that adverse childhood experiences (ACEs) are associated with a higher likelihood of CPTSD symptoms, but potential mediating roles of self-kindness and self-judgement on the ACEs-CPTSD relationship remain understudied. Objective: The purpose of this study was to first examine the relationship between ACEs and CPTSD among Chinese college students, and then to test the mediating role of self-kindness and self-judgement on the ACEs-CPTSD relationship. Method: The study included 1361 college students for an online survey in May 2020. Demographic variables (e.g. age, gender, having sibling[s] or not, residence, family structure, and subjective socioeconomic status), ACEs, self-compassion (self-kindness and self-judgement subscales), and CPTSD symptoms were assessed. After controlling for demographic variables, a series of structural equation models tested the mediation hypothesis: indirect effects of self-kindness and self-judgement on the relationship between ACEs and CPTSD symptom. Results: ACEs of College students were positively associated with more severe CPTSD symptoms (posttraumatic stress disorder and disturbances in self-organization symptoms). Furthermore, these direct pathways were mediated by decreased self-kindness and increased self-judgement. Conclusions: Findings have substantial theoretical and treatment implications, including the two critical targets (i.e. lowering self-judgement and raising self-kindness) when treating complex PTSD.

PTSD and complex PTSD in treatment-seeking Danish soldiers: a replication of Folke et al. (2019) using the International Trauma Questionnaire

Background: While empirical support for the ICD-11 distinction between posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) is growing, empirical research into the ICD-11 model of CPTSD in military populations is scarce and inconsistent. Objective: To replicate a study from our own group identifying distinct classes based on CPTSD symptoms using the International Trauma Questionnaire (ITQ) and to identify predictors and functional outcomes associated with a potential distinction between PTSD and CPTSD. Method: Formerly deployed treatment-seeking Danish soldiers (N = 294) completed the ITQ and self-report measures of traumatic life events prior to treatment. Latent profile analysis (LPA) was used to extract classes based on CPTSD symptoms. Results: LPA revealed four classes; (1) high CPTSD symptoms ('CPTSD', 28.7%); (2) high PTSD symptoms and lower DSO symptoms ('PTSD', 23.5%); (3) high DSO symptoms ('DSO', 17.3%); and (4) low symptoms ('Low Symptoms', 30.5%). In comparison to the PTSD-class, CPTSD-class membership was not predicted by traumatic events in adult life and in childhood. The CPTSD class was more often single/divorced/widowed compared to the PTSD class. Moreover, the CPTSD class more often used psychotropic medicine compared to the DSO-class and Low Symptoms-class. Conclusion: Using the ITQ, this study yields empirical support for the ICD-11 model of CPTSD within a clinical sample of veterans. The results replicate findings from our previous study that also identified distinct profiles of ICD-11 PTSD and CPTSD.

Sex differences in trauma exposure and symptomatology in trauma-affected refugees

The aim of this cross-sectional study was to examine associations between sex, exposure to potentially traumatic events and pre-treatment symptomatology in trauma-affected refugees. We analyzed pre-treatment self-report questionnaires and clinical interviews from 318 refugees with post-traumatic stress disorder (PTSD) in a specialized mental health clinic. Results show that twice as many females reported exposure to family violence (p = .001) and sexual abuse (p = .004), whereas men were at least three times as likely to report exposure to torture (p <0.001), imprisonment (p < .001), and combat (p < .001). Men reported exposure to more trauma types (p < .001). Women reported more depression (p = .001), anxiety (p = .008) and somatization (p = 0.001), whereas men were diagnosed significantly more with enduring personality change after catastrophic experience (p < .001). Additionally, trauma burden was significantly associated with PTSD (p = .001) and depression (p = .039) scores for women but not men, and imprisonment was associated with a higher PTSD score in women (p = 0.037) but not men. Our findings highlight sex differences in trauma exposure and symptomatology in trauma-affected refugees in host countries, that should be considered when developing mental health interventions for this underserved population.

Using Latent Class Analysis to Support the ICD-11 Complex Posttraumatic Stress Disorder Diagnosis in a Sample of Homeless Adults

The 11th revision of the International Classification of Diseases (ICD-11), ratified at the World Health Assembly in May 2019, introduced revised diagnostic guidelines for posttraumatic stress disorder (PTSD) as well as a separate diagnosis of complex PTSD (CPTSD). We aimed to test the new ICD-11 symptom structure for PTSD and CPTSD in a sample of individuals who have experienced homelessness. Experiences of trauma exposure and the associated mental health outcomes have been underresearched in this population. A sample of adults experiencing homelessness (N = 206) completed structured and semi-structured interviews that collected information about trauma exposure and symptoms of PTSD and CPTSD. We conducted a latent class analysis (LCA) using six symptom clusters (three PTSD symptom clusters that are components of CPTSD and three CPTSD symptom clusters). All participants reported trauma exposure, with 88.6% having experienced at least one event before 16 years of age. Four distinct classes of participants emerged in relation to the potential to meet the diagnosis: LCA CPTSD (n = 122, 59.8%), LCA no diagnosis (n = 27: 13.2%), LCA PTSD (n = 33; 16.2%), and LCA disturbance in self-organization (DSO; n = 22; 10.8%). Of note, participants with an ICD-11 CPTSD as well as those with an ICD-11 PTSD diagnosis fell into the LCA CPTSD class. Our findings provide some support for the distinction between CPTSD and PTSD within this population specifically but potentially have broader implications. Clear diagnoses will allow targeted PTSD and CPTSD treatment development.

PTSD with secondary psychotic features among trauma-affected refugees: The role of torture and depression

This cross-sectional study examined the prevalence of PTSD with secondary psychotic symptoms (PTSD-SP), its comorbidities, and its association with torture and depression in treatment-seeking refugees. Data were pooled from the Danish Database on Refugees with Trauma (DART). The sample represents approximately 90% of trauma-affected refugee-patients (N = 627) attending a Danish psychiatric outpatient clinic from 2008 to 2013. PTSD, secondary psychotic symptoms, and comorbidities were assessed with structured and routine clinical interviews. The association of PTSD-SP with torture and depression was investigated using hierarchical logistic regression. The prevalence of PTSD-SP in treatment-seeking refugees with PTSD was 30%. Among these, 44% fulfilled the criteria for Enduring Personality Change After Catastrophic Experience (EPCACE). Psychotic symptoms comprised hallucinations and persecutory delusions, often reflecting trauma-related themes. Comorbidity with depression was high (79%). Neither torture, nor other war-trauma (ex-combatant, imprisonment, civilian war trauma) predicted PTSD-SP, but comorbid depression did. Depression only explained a small amount of the total PTSD-SP variance. Results indicate that PTSD-SP is common in treatment-seeking refugees. However, its etiology is poorly understood. This highlights the need for further research to improve diagnosis and treatment for this patient group.

Traumatic experiences, ICD-11 PTSD, ICD-11 complex PTSD, and the overlap with ICD-10 diagnoses

OBJECTIVES

This study investigated the frequency of traumatic experiences, prevalence rates of ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD), and overlap with ICD-10 classified disorders in outpatient psychiatry.

METHOD

Overall, 165 Danish psychiatric outpatients answered the International Trauma Questionnaire, the Life Event Checklist, and the World Health Organization Well-being Index. ICD-10 diagnoses were extracted from the hospital record. Chi-square analysis, t-tests, and conditional probability analysis were used for statistical analysis.

RESULTS

Nearly, all patients (94%) had experienced at least one traumatic event. CPTSD (36%) was more common than PTSD (8%) and had considerable overlap with ICD-10 affective, anxiety, PTSD, personality, adjustment and stress-reaction disorders, and behavioural and emotional disorders with onset usually occurring in childhood and adolescence. ICD-11 PTSD overlapped with ICD-10 anxiety, PTSD, adjustment and stress-reaction disorders, and behavioural and emotional disorders with onset usually occurring in childhood and adolescence. A subgroup of patients with ICD-10 PTSD (23%) did not meet criteria for ICD-11 PTSD or CPTSD.

CONCLUSION

Traumatic experiences are common. ICD-11 CPTSD is a highly prevalent disorder in psychiatric outpatients. One quarter with ICD-10 PTSD did not meet criteria for either ICD-11 PTSD or CPTSD. PTSD and CPTSD had considerable overlap with ICD-10 disorders.

Complex posttraumatic stress disorder in Chinese young adults using the International Trauma Questionnaire (ITQ): A latent profile analysis

BACKGROUND

The ICD-11 includes posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as two distinct disorders. Several empirical studies have supported the distinction between PTSD and CPTSD in various trauma population and different culture backgrounds. However, research documenting qualitatively distinction between PTSD and CPTSD using the International Trauma Questionnaire (ITQ) in a large general population from non-English-speaking countries is limited.

METHODS

Self-report measures were used to assess CPTSD, dissociation, depression, and posttraumatic growth in a sample of 1,760 Chinese college students who had experienced at least one traumatic event. Latent profile analysis was utilized to identify the number of classes based on the 18-item version of ITQ.

RESULTS

A four-class solution (low symptoms, disturbance of self-organization, PTSD, CPTSD) was the most appropriate one in our study. Compared to the PTSD class, the CPTSD class was associated with more serious psychopathology symptoms.

LIMITATIONS

Sample characteristics in this study limit its generalizability to other population (e.g., low educational level, clinical sample). The type of traumatic event in predicting distinct classes should also be investigated in future studies.

CONCLUSIONS

Distinction between PTSD and CPTSD as ICD-11 proposed was supported in a Chinese young adult sample. DSO symptoms might inhibit healing and recovery process, and subsequent intervention could consider treat CPTSD based on addressing DSO symptoms.

Evidence for the coherence and integrity of the complex PTSD (CPTSD) diagnosis: response to Achterhof et al., (2019) and Ford (2020)

This letter to the editor responds to a recent EJPT editorial and following commentary which express concerns about the validity of the ICD-11 complex PTSD (CPTSD) diagnosis. Achterhof and colleagues caution that latent profile analyses and latent class analyses, which have been frequently used to demonstrate the discriminative validity of the ICD-11 PTSD and CPTSD constructs, have limitations and cannot be relied on to definitively determine the validity of the diagnosis. Ford takes a broader perspective and introduces the concept of 'cPTSD' which describes a wide ranging set of symptoms identified from studies related to DSM-IV, DSM-V and ICD-11 and proposes that the validity of the ICD-11 CPTSD is in question as it does not address the multiple symptoms identified from previous trauma-related disorders. We argue that ICD-11 CPTSD is a theory-driven, empirically supported construct that has internal consistency and conceptual coherence and that it need not explain nor resolve the inconsistencies of past formulations to demonstrate its validity. We do agree with Ford and with Achterhof and colleagues that no one single statistical process can definitively answer the question of whether CPTSD is a valid construct. We reference several studies utilizing many different statistical approaches implemented across several countries, the overwhelming majority of which have supported the validity of ICD-11 as a unique construct. We conclude with our own cautions about ICD-11 CPTSD research to date and identify important next steps.

Trauma-affected refugees treated with basic body awareness therapy or mixed physical activity as augmentation to treatment as usual-A pragmatic randomised controlled trial

BACKGROUND

The prevalence of post-traumatic stress disorder (PTSD) is estimated to be as high as 30% among refugees. The coexistence of prevalent chronic pain is believed to maintain symptoms of PTSD and add complexity to the condition. Despite this, little evidence exists on how to treat PTSD and comorbid conditions best in trauma-affected refugees.

AIM

The aim of the present study was to investigate if adding either BBAT or mixed physical activity to the treatment as usual (TAU) for trauma-affected refugees with PTSD would increase the treatment effect compared to TAU alone.

METHOD

Randomised controlled trial, 3-armed parallel group superiority study, conducted at Competence Centre for Transcultural Psychiatry, Denmark. Participants were adult trauma-affected refugees with PTSD. Allocation ratio was 1:1:1, stratified for PTSD severity and gender. An open-label design was applied due to the nature of the intervention. Participants were randomised to receive either individual basic body awareness therapy (group B) or individual mixed physical activity (group M) one hour/week for 20 weeks plus TAU, or TAU only (group C). The primary outcome was PTSD severity measured by Harvard Trauma Questionnaire (HTQ). Trial registration: ClinicalTrials.gov, NCT01955538.

RESULTS

Of the 338 patients included (C/B/M = 110/114/114), 318 patients were eligible for intention-to-treat analysis (C/B/M = 104/105/109). On the primary outcome, intention-to-treat as well as per-protocol analyses showed small but significant improvement on scores from pre- to post-treatment in all three groups but with no significant difference in improvement between groups.

CONCLUSIONS

The findings do not provide evidence that either BBAT or mixed physical activity as add-on treatment bring significantly larger improvement on symptoms of PTSD compared to TAU alone for adult, trauma-affected refugees. There is a need for studies on potential subpopulations of trauma-affected refugees who could benefit from physical activity as a part of their treatment.

Prevalence and comorbidity of the ICD-11 and DSM-5 for PTSD caseness with previous diagnostic manuals among the Japanese population

Background: The diagnostic criteria for posttraumatic stress disorder (PTSD) differ between DSM-5 and ICD-11, which may affect the estimation of prevalence. Objective: To investigate the concordance of ICD-11 and DSM-5, as compared to ICD-10 and DSM-IV, regarding PTSD caseness among Japanese people who had experienced different potentially traumatic events. In addition, we estimated the comorbidity with major depressive disorder and generalized anxiety disorder according to these four diagnostic manuals. Method: A web-based survey (n = 6,180) was conducted from November 2016 to March 2017. Participants completed the PTSD Checklist for DSM-5, and other standardized measures of PTSD, depression, and anxiety. Results: The prevalence of PTSD caseness according to ICD-11 was significantly lower as compared to DSM-IV, DSM-5, and ICD-10. Cohen's kappa between DSM-5 and ICD-11 was 0.79, indicating substantial agreement. Comorbidity with depression was significantly higher in unique DSM-5 cases than in unique ICD-11 cases. Unique DSM-5 PTSD cases were significantly stronger functionally impaired than unique ICD-11 PTSD cases. Conclusions: Although requiring fewer items, the ICD-11 showed substantial agreement with DSM-5 regarding PTSD caseness. The lower comorbidity rates in unique cases may support the concept of the ICD-11 which intends to reduce comorbidity by identifying the core elements of PTSD.

Examining the Discriminant Validity of Complex Posttraumatic Stress Disorder and Borderline Personality Disorder Symptoms: Results From a United Kingdom Population Sample

Complex posttraumatic stress disorder (CPTSD) was added to the diagnostic nomenclature in the 11th revision of the International Classification of Diseases (ICD-11). Although considerable evidence exists supporting the construct validity of CPTSD, the distinguishability of CPTSD symptoms from those of borderline personality disorder (BPD) has been questioned. The present study examined the discriminant validity of CPTSD and BPD symptoms among a trauma-exposed population sample from the United Kingdom (N = 546). Participants completed self-report measures of CPTSD and BPD symptoms, and their latent structure was assessed using exploratory structural equation modeling (ESEM). A three-factor model with latent variables reflecting PTSD, disturbances in self-organization (DSO), and BPD symptoms provided the best fit of the data, χ² (399, N = 546) = 1,650, p < .001; CFI = .944; TLI = .930; RMSEA = .077, 90% CI [.073, .081]. We identified multiple symptoms distinctive to individual constructs (e.g., disturbed relationships and suicidality) as well as symptoms shared across the constructs (e.g., affective dysregulation). The PTSD, β = .24; DSO, β = .23; and BPD, β = .27, latent variables were positively and significantly associated with childhood interpersonal trauma. The current findings support the discriminant validity of CPTSD and BPD symptoms and highlight various phenomenological signatures of each construct as well as demonstrate how these constructs share important similarities in symptom composition and exogenous correlates.

Modeling Patterns of Polyvictimiztion and Their Associations with Posttraumatic Stress Disorder and Complex Posttraumatic Stress Disorder in the Israeli Population

Although evidence is accumulating for the conceptual validity of the ICD-11 proposal for posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD), our understanding of the specificity of trauma-related predictors is still evolving. Specifically, studies utilizing advanced statistical methods to model the association between trauma exposure and ICD-11 proposals of traumatic stress and differences in profiles of trauma exposure are lacking. Additionally, time since trauma and a clear memory of the trauma are yet to be examined as predictors of PTSD and CPTSD. We analyzed trauma exposure as reported by a general population sample of Israeli adults (N = 834), using latent class analysis, and the resultant classes were used in regression models to predict PTSD and CPTSD operationalized both dimensionally and categorically. Four distinct groups were identified: child and adult interpersonal victimization, community victimization-male, community victimization-female, and adult victimization. These groups were differentially related to PTSD and CPTSD, with only child and adult interpersonal victimization consistently predicting CPTSD and disturbances in self-organization. When modeled dimensionally, PTSD was associated with the child and adult interpersonal victimization and adult victimization groups, whereas only the child and adult interpersonal victimization group was predictive of PTSD when operationalized categorically. The roles of time since trauma and a clear memory of the trauma differed across PTSD and CPTSD. These findings support the use of trauma typologies for predicting PTSD and CPTSD and provide important insight into the distribution of trauma exposure in the Israeli population.

Complex Posttraumatic Stress Disorder Symptom Profiles in Traumatized Refugees

Although it is well documented that exposure to severe, cumulative trauma and postdisplacement stress increases the risk for posttraumatic stress symptom disorder (PTSD), less is known about the representation and predictors of complex PTSD (CPTSD) symptoms in refugee populations. We examined PTSD and CPTSD symptom profiles (co-occurring PTSD and disturbances in self-organization [DSO] symptoms) and their premigration, postmigration, and demographic predictors, using latent class analysis (LCA), in a cohort of 112 refugees resettled in Australia. The LCA identified a four-factor model as the best fit to the data, comprising classes categorized as: (a) CPTSD, exhibiting high levels of PTSD and DSO symptoms (29.5%); (b) PTSD only (23.5%); (c) high affective dysregulation (AD) symptoms (31.9%); and (d) low PTSD and DSO symptoms (15.1%). Membership in the CPTSD and PTSD classes was specifically associated with cumulative traumatization, CPTSD OR = 1.56, 95% CI [1.15, 2.12], and PTSD OR = 1.64, 95% CI [1.15, 2.34]; and female gender, CPTSD OR = 14.18, 95% CI [1.66, 121.29], and PTSD OR = 16.84, 95% CI [1.78, 159.2], relative to the low-symptom class. Moreover, CPTSD and AD class membership was significantly predicted by insecure visa status, CPTSD OR = 7.53, 95% CI [1.26, 45.08], and AD OR = 7.19, 95% CI [1.23, 42.05]. These findings are consistent with the ICD-11 model of CPTSD and highlight the contributions of cumulative trauma to CPTSD and PTSD profiles as well as of contextual stress from visa uncertainty to DSO symptom profiles in refugee cohorts, particularly those characterized by AD.

ICD-11 PTSD and complex PTSD in treatment-seeking Danish veterans: a latent profile analysis

Background: The WHO International Classification of Diseases, 11th version (ICD-11), includes a trauma-related diagnosis of complex posttraumatic stress disorder (CPTSD) distinct from posttraumatic stress disorder (PTSD). Results from previous studies support the validity of this distinction. However, no studies to date have evaluated the ICD-11 model of PTSD and CPTSD in treatment-seeking military veterans. Objective: To determine if the distribution of symptoms in treatment-seeking Danish veterans was consistent with the ICD-11 PTSD and CPTSD symptom profiles. Based on previous studies, we hypothesized that separate classes representing PTSD and CPTSD would be found that membership of a potential CPTSD-class would be predicted by a larger number of childhood traumas, and that a potential distinction between PTSD and CPTSD would be supported by differences in sociodemographic and functional outcomes. Method: Participants (N = 1,541) were formerly deployed Danish soldiers who completed proxy measures of ICD-11 PTSD and disturbances in self-organization (DSO) symptoms, along with self-report measures of traumatic life events, prior to starting treatment at the Military Psychology Department of the Danish Defence. Results: All hypotheses were supported. Latent profile analysis (LPA) revealed separate classes representing PTSD and CPTSD. In comparison to the PTSD-class, membership of the CPTSD-class was predicted by more childhood traumatic experiences, and members of this class were more likely being single/divorced/widowed and more likely to use psychotropic medication. Besides a PTSD-class and a CPTSD-class, LPA revealed a Low Symptoms-class, a Moderate DSO-class, a Hyperarousal-class, and a High DSO-class, with clear differences in functional outcomes between classes. Conclusion: Findings replicate previous studies supporting the distinction between ICD-11 PTSD and CPTSD. In addition, there seem to be groups of treatment-seeking military veterans that do not fulfil full criteria for a trauma-related disorder. Further research should explore subsyndromal PTSD and CPTSD profiles in veterans and other populations.

The factor structure of complex PTSD in combat-exposed Filipino soldiers

The World Health Organization recently released the 11th revision of the International Classification of Diseases with the inclusion of Complex Posttraumatic Stress Disorder (CPTSD). Despite the emerging research examining the symptom structure of CPTSD, to date, none so far have reached consensus on what best represents CPTSD, particularly in soldiers who are exposed regularly in combat situations. This study examined seven latent CPTSD models in a sample of Filipino combat-exposed soldiers (n = 450). Results of confirmatory factor analyses indicated that the correlated 6 factor first-order model (model 2), comprising of re-experiencing, avoidance, persistent sense of current threat, affective dysregulation, negative self-concept, and disturbances in relationships, has the best fit. These findings have implications for understanding CPTSD as a diagnostic entity and provide information on the assessment and crafting of complex trauma interventions, particularly among Filipino combat-exposed soldiers.

Complex trauma, PTSD and complex PTSD in African refugees

Background: The introduction of the diagnosis of complex posttraumatic stress disorder (CPTSD) by ICD-11 is a turning point in the field of traumatic stress studies. It's therefore important to examine the validity of CPTSD in refugee groups exposed to complex trauma (CT) defined as a repeated, prolonged, interpersonal traumatic event. Objective: The objective of this study was to compare DSM-5 and ICD-11 post-traumatic stress disorder diagnoses and to evaluate the discriminant validity of ICD-11 PTSD and CPTSD constructs in a sample of treatment-seeking refugees living in Italy. Method: The study sample included 120 treatment-seeking African refugees living in Italy. All participants were survivors of at least one CT. PTSD and CPTSD diagnoses were assessed according to both DSM-5 and ICD-11 criteria. Results: Findings revealed that 79% of the participants met the DSM-5 criteria for PTSD, 38% for ICD-11 PTSD and 30% for ICD-11 CPTSD. Generally, ICD-11 CPTSD items evidenced strong sensitivity and negative predictive power, low specificity and positive predictive power. Latent class analysis results identified two distinct groups: (1) a PTSD class, (2) a CPTSD class. None of the demographic and trauma-related variables analysed was significantly associated with diagnostic group. On the other hand, the months spent in Italy were significantly associated with PCL-5 score. Conclusions: Findings extend the current evidence base to support the discriminant validity of PTSD and CPTSD amongst refugees exposed to torture and other gross violations of human rights. The results suggest also that, in the post-traumatic phase, the time spent in a 'safe place' condition contributes to improve the severity of post-traumatic symptomatology, but neither this variable nor other socio-demographic factors seem to contribute to the emergence of complex PTSD. Further investigations are needed to clarify which specific vulnerability factors influence the development of PTSD or CPTSD in refugees exposed to complex trauma.

Complex posttraumatic stress disorder (CPTSD) following captivity: a 24-year longitudinal study

Background: The World Health Organization(WHO) International Classification of Diseases, 11th version (ICD-11), has proposed a new trauma-related diagnosis of complex posttraumatic stress disorder (CPTSD), separate and distinct from posttraumatic stress disorder (PTSD). However, to date, no study has examined CPTSD over time. Objectives: This prospective study aimed to examine predictors and outcomes of latent classes of PTSD and CPTSD following war captivity. Method: A sample of 183 Israeli former prisoners of the 1973 Yom Kippur War (ex-POWs) participated in a 24-year longitudinal study with three waves of measurements (T1: 1991, T2: 2008, and T3: 2015). Participants completed validated self-report measures, and their cognitive performance was assessed using the Montreal Cognitive Assessment (MoCA). Results: Estimated rates of PTSD and CPTSD were high at all waves, with PTSD rates higher than CPTSD. A Latent Class Analysis (LCA) identified three main classes at T2: (1) a small class with low probability to meet PTSD and CPTSD clusters criteria (15.26%); (2) a class high only in PTSD symptoms (42.37%) and (3) a class high only in CPTSD symptoms (42.37%). Importantly, higher levels of psychological suffering in captivity at T1 were associated with higher odds of being in the CPTSD class at T2. In addition, CPTSD at T2 was more strongly associated with low self-rated health, functional impairment, and cognitive performance at T3, compared to the PTSD only class. Conclusions: Adulthood prolonged trauma of severe interpersonal intensity such as war captivity is related to CPTSD, years after the end of the war. Exposure to psychological suffering in captivity is a risk factor for future endorsement of CPTSD symptoms. CPTSD among ex-POWs is a marker for future dire mental health and functional consequences.

Why do I have to suffer? Symptom management, views and experiences of persons with a CPTSD: a grounded theory approach

BACKGROUND

For the 11th version of the International Classification of Diseases, a new stress related diagnosis has been proposed: complex post-traumatic stress disorder (CPTSD). It is described as a chronic condition with several severe and concurrent symptoms. In the literature, these symptoms are discussed as a common reason for seeking psychiatric treatment as they can influence and impair the quality of life not only for affected persons but also for their social and familial system.

AIM

This research studies symptom management in everyday life by exploring and reconstructing the views, perceptions, experiences, facilitators and barriers of adults with CPTSD.

METHODS

A theoretical sampling was used to recruit 18 to 65 years old patients diagnosed with CPTSD from an inpatient setting. The 17 semi-structured interviews were audio recorded and transcribed verbatim. The transcriptions were uploaded into MAXQDA, and a Grounded Theory method based on Corbin and Strauss was used to analyse the data.

RESULTS

We provide a process model with 5 interacting phases: trauma experience, emotional ignorance, overcompensation, paroxysm, and perspectives. Each phase is specified with subcategories.

CONCLUSIONS

The participants did not recognise their symptoms as such and were unaware of their diagnosis for many years. Nevertheless, they used various resources and were able to develop skills and techniques to deal with their symptoms and to function on a day-to-day basis. Overall, the process of symptom management was extremely exhausting for the participants and they felt left alone with it. The participants were eager to gain support from healthcare professionals and, when necessary, financial support from the government. Thus, these results indicate an essential need to develop support and tailored interventions for the symptom management of persons with a CPTSD.

Hyperactivation and hypoactivation affective dysregulation symptoms are integral in complex posttraumatic stress disorder: Results from a nonclinical Israeli sample

OBJECTIVES

The current study sought to further assess the nature of the affect dysregulation (AD) cluster of the International Classification of Diseases-11 (ICD-11) proposal for complex posttraumatic stress disorder (CPTSD) in a nonclinical sample.

METHODS

An online survey sample from Israel (n = 618) completed a disorder-specific measure (International Trauma Questionnaire) of PTSD and CPTSD along with the Life Events Checklist and the World Health Organization Well-Being Index.

RESULTS

Estimated prevalence rates of PTSD and CPTSD were 9.2% and 1.0%, respectively. Confirmatory factor analysis results indicated that AD symptoms are better conceived as two correlated dimensions of hyperactivation and hypoactivation symptoms. Latent class analysis results indicated that CPTSD was clearly distinguishable from PTSD. CPTSD class membership was associated with higher levels of traumatization and poorer psychological well-being scores.

CONCLUSIONS

Findings support the discriminant validity of the ICD-11 proposals for PTSD and CPTSD in a nonclinical sample using a disorder-specific measure. The results provide further evidence that the final symptom profile for CPTSD in ICD-11 should model the AD cluster using both hyperactivation and hypoactivation symptoms.

Mastering life together - symptom management, views, and experiences of relatives of persons with CPTSD: a grounded theory study

Background

Complex posttraumatic stress disorder is described as a chronic condition with several severe and concurrent symptoms. Symptoms influence and impair not only the affected individuals but also their social surroundings and their relatives. The literature describes relatives as a key factor in managing symptoms, both as a barrier and a facilitator.

Aim

This research aimed to explore and to reconstruct the views, perceptions, experiences, facilitations and barriers of relatives who support the symptom management of persons with CPTSD in everyday life.

Methods

A theoretical sampling was used to recruit for an interview 18- to 65-year-old relatives of patients with diagnosed CPTSD. The 17 semi-structured interviews were audio-recorded and transcribed verbatim. The transcriptions were uploaded into MAXQDA, and a Grounded Theory method based on that of Corbin and Strauss was used to analyse the data.

Results

We provide a process model with 5 interacting phases: the initial situation, state of permanence, being an anchor, recognizing limits, and potential outcomes. Each phase is further divided into subcategories.

Discussion

Participants experienced their condition as unpredictable. Although they mastered different strategies through own exploration and in cooperation, there is a clear need for more education, advice and support for relatives caring for those affected by CPTSD. Health care services should consider providing family support, educational services and increase the involvement of relatives in treatment. Over all, well-supported relatives can play a facilitative, key role in improving symptom management.

Stress management versus cognitive restructuring in trauma-affected refugees-A pragmatic randomised study

The aim of this randomised trial was to compare the effectiveness of stress management (SM) versus cognitive restructuring (CR) in trauma-affected refugees. The intention-to-treat sample comprised 126 refugees with PTSD (SM = 62, CR = 64). The treatment consisted of 16 sessions of psychotherapy with manualised SM or CR in addition to 10 sessions with a medical doctor (psychoeducation and pharmacological treatment). The primary outcome was PTSD symptom severity (Harvard Trauma Questionnaire). Secondary outcomes were symptoms of depression and anxiety (Hopkins Symptom Checklist-25, Hamilton Depression and Anxiety Ratings), quality of life (WHO-5), functioning (Global Assessment of Functioning, Sheehan Disability Scale), pain (Visual Analogue Scale) and somatisation (Symptom Checklist). There was no difference in the primary outcome between groups. A significant group difference was found on the Hamilton Anxiety Rating with the SM group improving more than the CR group (effect size 0.46) indicating that methods in SM could potentially be helpful in this population.
