The Relationship of Complex Post-traumatic Stress Disorder and Post-traumatic Stress Disorder in a Culturally Distinct, Conflict-Affected Population: A Study among West Papuan Refugees Displaced to Papua New Guinea

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.

Considerations in designing trauma-focused interventions for displaced Afghan women

In light of the 2021 United States military withdrawal from Afghanistan, as well as the humanitarian crises of mass displacement and subsequent health system strain that have ensued, practitioners worldwide will need to develop a more nuanced understanding of the adverse life experiences that women from Afghanistan frequently endorse. As they bear a disproportionate impact of constraints within Afghan society, and as patriarchal systems affect most of their life domains, women from Afghanistan may present with high levels of baseline trauma upon resettlement, and health systems may seek to attenuate this distress; However, the nature of these traumatogenic events may shape women's receptivity to psychosocial interventions, particularly those which are at least partially rooted in Western modalities. In the absence of sufficient literature on evidence-based interventions for this population, a diversity of ethnographic and clinical literature is synthesized, including literature on interventions alleged to be compatible with Afghan norms. As it will be essential to support Afghan women's mental health following social reorganization on a massive scale, considerations arising from the interdisciplinary literature are offered so that they may inform the development of structured, trauma-focused interventions and so that the health systems with which they interface may be better prepared to serve them.

Personal experience, posttraumatic symptomatology, and meaning in life during the first months of the COVID-19 pandemic

The traumatic subjective distress and personal meaning in life were examined in the context of the first months of the COVID-19 pandemic sanitary crisis and home lockdown.

METHOD

A total of 543 participants answered an online survey that included questions about the individual characteristics of the pandemic experience, the Impact of Event Scale-Revised, and the Personal Meaning Profile-Brief.

RESULTS

Nearly all of life impaired areas, having the suspicion of being ill with COVID-19, having lost a close person to this virus, and having been accompanied during the lockdown were experiences associated with higher PTSD symptoms. Posttraumatic symptomatology was inversely correlated with areas of meaning in life. Lastly, a higher number of affected areas and a negative subjective lockdown circumstance explained greater total PTSD symptoms.

CONCLUSION

Specific pandemic experiences and lockdown circumstances affected the presence of posttraumatic symptoms. The personal meaning of life seems to be involved in the process of less adverse traumatic consequences.

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.

Quality of mental health questionnaires in conflict-affected adult populations in low and middle income countries: A systematic review

BACKGROUND

Accurate measurement of mental health disorders in conflict-affected populations is crucial for improving mental health care for these populations. Most studies to develop mental health questionnaires for conflict-affected populations are conducted in high income countries despite the vast majority of conflict-affected populations residing in Low and Middle Income Countries (LAMICs). The aim of this systematic review is to assess the quality of questionnaires for mental disorders that have been either developed or validated in conflict- affected settings in LAMICs.

METHODS

A systematic review of 5 databases (CINAHL Plus, EMBASE, Global Health, MEDLINE and PsycINFO) was conducted to identify validation studies for questionnaires measuring mental health disorders in adult conflict-affected population in LAMICs. Well-established psychometric criteria evaluating reliability, validity and responsiveness of questionnaires were applied for quality appraisal.

RESULTS

Thirty validation studies were included in this review, which reported on data for 33 questionnaires. Twenty-four were questionnaires that had been originally developed in different settings and adapted for use with a new conflict-affected population and 9 had been newly developed for the conflict-affected population being studied. Overall, there was high variability in the quality of evidence for the questionnaires with moderate evidence for the validity and reliability of included questionnaires but no responsiveness data reported.

CONCLUSION

There has been increasing recognition of the particular importance of psychometrics in this field to facilitate the development of good quality mental health questionnaires suitable for use in LAMICs. However, this review highlighted the current limited quantity and quality of such questionnaires.

Responding to the new International Classification of Diseases-11 prolonged grief disorder during the COVID-19 pandemic: a new bereavement network and three-tiered model of care

The field of bereavement research and care is at a tipping point. The introduction of prolonged grief disorder (PGD) in the International Classification of Diseases (ICD-11) has ignited clinical interest in this new disorder, along with debate over challenges in validating and implementing these new criteria. At the same time, the global COVID-19 pandemic has launched several local and international efforts to provide urgent support and comfort for individuals and communities suffering from grief. Recently, grief experts have called for a collective response to these complicated bereavements and possible increase in PGD due to COVID-19. Here we outline a new European network that aims to unite a community of grief researchers and clinicians to provide accessible, evidence-based support particularly during times of unprecedent crisis. The Bereavement Network Europe (BNE) has been developed with two main aims. Firstly, to develop expert agreed, internationally acceptable guidelines for bereavement care through a three-tiered approach. Secondly, to provide a platform for researchers and clinicians to share knowledge, collaborate, and develop consensus protocols to facilitate the introduction of PGD to diverse stakeholders. This article outlines the current status and aims of the BNE along with the plans for upcoming network initiatives and the three-tiered bereavement care guidelines in response to the COVID-19 pandemic.

ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD among organized violence survivors in modern South Korean history of political oppression

BACKGROUND AND OBJECTIVES

Construct and discriminant validity of the ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) has been examined worldwide. However, little is known about CPTSD in Korean population who are suffering with long-term responses of organized violence in their context.

DESIGN

This study conducted a cross-sectional survey to assess the construct and discriminant validity of the ICD-11 PTSD and CPTSD using the Korean International Trauma Questionnaire (ITQ) among organized violence survivors of past political oppression (from 1940s to 2010s) in South Korea.

METHOD

A total of 236 survivors and families completed the survey including the ITQ. A confirmatory factor analysis and a multinomial logistic regression were conducted.

RESULTS

A second-order eight-factor, the ICD-11 CPTSD model, best described the structure of CPTSD. Compared to the non-diagnosed group, having above median score of cumulative trauma was a risk factor for PTSD [Odds ratio (OR) = 3.18] and CPTSD (OR = 3.27). Having above median score of cumulative social stressors increased the risk of CPTSD, relative to PTSD (OR = 4.84), and to the non-diagnosed group (OR = 7.79).

CONCLUSIONS

The ITQ seemed applicable to the Korean culture, showing a valid construct and meaningfully distinguishing ICD-11 PTSD and CPTSD.

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.

ICD-11 PTSD and complex PTSD amongst Syrian refugees in Lebanon: the factor structure and the clinical utility of the International Trauma Questionnaire

OBJECTIVE

Support for ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) is growing; however, few studies include refugees or examine the clinical utility of PTSD/CPTSD classifications. This study sought to provide the first evaluations of (i) the factor structure of ICD-11 PTSD/CPTSD amongst refugees in the Middle East; and (ii) the clinical utility of the International Trauma Questionnaire (ITQ) to identify PTSD/CPTSD in a humanitarian context.

METHOD

Participants were 112 treatment-seeking Syrian refugees living in Lebanon. Factorial validity was assessed using confirmatory factor analysis (CFA) based on responses to the ITQ. Clinical utility of the ITQ was assessed through semi-structured interviews with six Lebanese psychotherapists.

RESULTS

Complex PTSD (36.1%) was more common than PTSD (25.2%), and no sex or age differences were observed at the prevalence or symptomatic levels. CFA results supported a two-factor higher-order model consistent with ICD-11 PTSD/CPTSD. Qualitative findings indicated that the ITQ is generally positively regarded, with some limitations and suggested modifications noted.

CONCLUSION

This is the first study to support the ICD-11 PTSD/CPTSD amongst refugees in the Middle East and the clinical utility of the ITQ in a humanitarian context. Findings support the growing evidence for the cross-cultural applicability of ICD-11 PTSD/CPTSD.

Factor structures of Complex Posttraumatic Stress Disorder and PTSD in a community sample of refugees from West Papua

OBJECTIVES

The intention to include a category of Complex Posttraumatic Stress Disorder (CPTSD) in ICD-11 has renewed interest in this construct. Although growing evidence from high income countries supports the construct validity of CPTSD, little parallel research has been undertaken across cultures. We tested theoretically supported CPTSD structures (a one-factor, six-factor, one-factor higher-order, and two-factor higher order structure) in a community sample of West Papuan refugees living in a remote town, Kiunga, in Papua New Guinea (PNG).

PROCEDURES

A community-wide survey was conducted (2016-2017; response rate 85.5%) amongst 486 West Papuans. Culturally adapted measures were applied to assess cumulative traumatic exposure, postmigration living difficulties (PMLDs), CPTSD symptoms, and functional impairment.

FINDINGS

A six factor structure for CPTSD provided the best fit to the data, consistent with our past study amongst West Papuans.

CONCLUSIONS

The cross-cultural validity of our findings is supported by the isolation of West Papuan participants from services treating traumatic stress. To further support the universal applicability of CPTSD, our findings need to be confirmed amongst other refugee groups from diverse cultural backgrounds.

Psychological Consequences of Human Trafficking: Complex Posttraumatic Stress Disorder in Trafficked Children

Trafficked children are frequently exposed to multiple traumatic events, including during their recruitment, transit, and exploitation. It has been hypothesized that such exposures can lead to the development of Complex Posttraumatic Stress Disorder (PTSD). Complex PTSD includes (in addition to the core PTSD symptoms of re-experiencing, avoidance, and hyperarousal) disturbances in affect regulation, dissociation, self-concept, interpersonal relationships, somatization, and systems of meaning. This historical cohort study aimed to investigate Complex PTSD in trafficked children with a diagnosis of PTSD and compare these with nontrafficked controls exposed to single or multiple trauma. Trafficked children were identified by keyword searches of the electronic health records of more than 250,000 mental health service users; a matched cohort of nontrafficked children was randomly selected. Regression models compared the number of Complex PTSD symptoms in trafficked children and non-trafficked children who had experienced multiple or single trauma. Fifty-one trafficked children were identified: eleven with a diagnosis of PTSD (22%). A high proportion of trafficked children with PTSD had Complex PTSD symptoms. Trafficked and non-trafficked children with PTSD who had been exposed to multiple trauma showed a greater number of Complex PTSD symptoms compared to nontrafficked children with PTSD exposed to single-event traumas. Somatic symptoms were noted for almost two-thirds of the trafficked children but only 10%-11% of the nontrafficked children. Child trafficking and multiple trauma exposure are associated with more complex posttraumatic presentations. A thorough clinical assessment at intake is crucial to ensure additional symptoms can be meaningfully incorporated into treatment plans.

ICD-11 complex PTSD among Israeli male perpetrators of intimate partner violence: Construct validity and risk factors

The International Classification of Diseases 11th Version (ICD-11) will include Complex Posttraumatic Stress Disorder (CPTSD) as a unique diagnostic entity comprising core PTSD and DSO (disturbances in self-organization) symptoms. The current study had three aims: (1) assessing the validity of CPTSD in a unique population of male perpetrators of intimate partner violence; (2) examining whether exposure to different types of traumatic events would be associated with the two proposed CPTSD factors, namely PTSD or DSO; and (3) assessing the differential association of various sociodemographic and symptom characteristics with each factor. Participants were 234 males drawn randomly from a sample of 2600 men receiving treatment at 66 domestic violence centers in Israel. Data were collected using the International Trauma Questionnaire (ITQ) - Hebrew version. Confirmatory factor analysis supported the factorial validity of ICD-11 CPTSD. Cumulative lifetime trauma and physical childhood neglect were associated with PTSD and DSO, while cumulative childhood violence exposure was associated only with DSO. Anxiety was associated only with DSO; depression more strongly with DSO than PTSD. Religious level contributed only to PTSD; compulsory military service only to DSO. The study supports the distinction between PTSD and DSO in the CPTSD construct and introduces the role of cultural variables.

Testing competing factor models of the latent structure of post-traumatic stress disorder and complex post-traumatic stress disorder according to ICD-11

With the publication of the International Statistical Classification of Diseases and Related Health Problems, 11th edition (ICD-11) due for release in 2018, a number of studies have assessed the factorial validity of the proposed post-traumatic stress disorder (PTSD) and complex (CPTSD) diagnostic criteria and whether the disorders are correlated but distinct constructs. As the specific nature of CPTSD symptoms has yet to be firmly established, this study aimed to examine the dimension of affect dysregulation as two separate constructs representing hyper-activation and hypo-activation. Seven alternative models were estimated within a confirmatory factor analytic framework using the International Trauma Questionnaire (ITQ). Data were analysed from a young adult sample from northern Uganda (n = 314), of which 51% were female and aged 18-25 years. Forty per cent of the participants were former child soldiers (n = 124) while the remainder were civilians (n = 190). The prevalence of CPTSD was 20.8% and PTSD was 13.1%. The results indicated that all models that estimated affective dysregulation as distinct but correlated constructs (i.e. hyper-activation and hypo-activation) provided satisfactory model fit, with statistical superiority for a seven-factor first-order correlated model. Furthermore, individuals who met the criteria for CPTSD reported higher levels of war experiences, symptoms of anxiety and depression, and somatic problems than those with PTSD only and no diagnosis. There was also a much larger proportion of former child soldiers that met the criteria for a CPTSD diagnosis. In conclusion, these results partly support the factorial validity of the ICD-11 proposals for PTSD and CPTSD in a non-Western culture exposed to mass violence. These findings highlight that more research is required across different cultural backgrounds before firm conclusions can be made regarding the factor structure of CPTSD using the ITQ.
