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

Digital mental health interventions for the mental health care of refugees and asylum seekers: Integrative literature review

This study aimed to provide a critical analysis of the current literature on the use of digital mental health interventions (DMHIs) for the management and treatment of mental health disorders among refugees and asylum seekers. These groups are among the most disadvantaged compared to the general population in terms of health and socio-economic status, due to conflicts and wars. The number of refugees fleeing their home countries is growing exponentially, and refugees experience trauma, torture, persecution and human right abuses, which have a profound effect on their mental health and overall well-being. The researchers conducted an integrative literature review from electronic databases Medline, CINAHL and Google Scholar, selecting articles published in English from 2010 to 2023. The thematic analysis of the 10 articles identified in the review revealed four main themes and two sub-themes: (1) types of digital health intervention/apps used; (2) barriers encountered in digital health intervention; (3) user experience of the digital health intervention and (4) mapping gaps. Two sub-themes were identified located in Theme 2: (2.1) Language and demographic barriers and (2.2) Structural barriers. The study showed that the use of DMHIs was associated with positive experiences among refugees and asylum seekers. Limited mental health care is offered to refugees and asylum seekers due to a range of logistical, political, economic, geographical, language, cultural and social barriers. DMHIs have the potential to overcome and/or moderate these barriers. The study concludes that the scaled implementation of effective DMHIs holds the possibility to improve the wider distribution of mental health care among refugees and asylum seekers. However, further research is needed to confirm the effectiveness of DMHIs and to scale up studies for their utilisation among this group. In summary, this study highlights the potential of DMHIs in improving the mental health care of refugees and asylum seekers. The results of this study have important implications for mental health service providers, policymakers and researchers to address the mental health needs of this vulnerable/priority group.

Intergenerational associations between childhood maltreatment, post-traumatic stress symptoms, and chronic pain in young adult offspring and their parents

Findings have revealed a strong link between exposure to child maltreatment (CM) and later chronic pain. Concurrently, other findings have been grounded in the understanding that CM consequences may not end with the exposed individual, rather, they extend to their offspring. However, little is known regarding the possible intergenerational transmission of chronic pain following CM. This study examines whether chronic pain among parents and their young adult offspring may be associated with parental exposure to CM. Three hundred ninety-three parent-offspring dyads (parents' mean age = 58, SD = 5.91 years; offspring's mean age = 27, SD = 3.91 years) completed self-report questionnaires, assessing CM (CTQ), posttraumatic stress (PTS) and disturbances in self-organisation (DSO) symptoms (ITQ), and chronic pain. CM was associated with chronic pain mediated by DSO symptoms among parents (indirect effect = 0.77; p = 0.007) and PTS symptoms among offspring (indirect effect = 0.285; p = 0.005). Offspring chronic pain was significantly associated with parental CM through two intergenerational paths: the mediation of parents' DSO symptoms and chronic pain (indirect effect = 0.298; p = 0.011), and through parents' PTS symptoms and offspring's PTS symptoms (indirect effect = 0.077; p = 0.004). This study's findings support the relevance of the intergenerational transmission of chronic pain following parental exposure to CM. Furthermore, the findings reveal complex PTS symptoms as a possible underlying mechanism for the intergenerational associations of chronic pain following CM.

Gender, sex and complex PTSD clinical presentation: a systematic review

Background: Post-traumatic stress disorder (PTSD) prevalence and clinical presentation reportedly vary with gender and/or sex. Equivalent complex PTSD (CPTSD) research is in its relative infancy and to date no systematic review has been conducted on this topic.Objective: To systematically review the literature and provide a narrative addressing the question of whether gender and/or sex differences exist in CPTSD prevalence and clinical presentation.Method: Embase, PsycINFO, PTSDpubs, PubMed, Web of Science, EThOS and Google Scholar were searched. Twelve papers were eligible for inclusion. Data were extracted and synthesised narratively.Results: Four themes were identified: (i) the reporting of gender and/or sex; (ii) index trauma; (iii) CPTSD prevalence rates; and (iv) CPTSD clinical presentation. Findings were mixed. Nine papers reported prevalence rates: eight found no gender and/or sex differences; one found higher diagnostic rates among women and/or females. Four papers reported clinical presentation: one reported higher cluster-level scores among women and/or females; two used single gender and/or sex samples; and one found higher scores in two clusters in men and/or males. Most papers failed to report in gender- and/or sex-sensitive ways.Conclusions: Gender- and sex-sensitive research and clinical practice is needed. Awareness in research and clinical practice is recommended regarding the intersect between identity and the experience and expression of complex trauma.

Predicting post-traumatic stress disorder: The complex relationship between burnout, intentions to leave and emotional support among health care professionals

BACKGROUND

Health care professionals working in delivery rooms often encounter stressful situations. Understanding their challenges and the support they receive is essential for improving their well-being and consequently patient care.

PURPOSE

Examining the relationship between burnout, intentions to leave, post-traumatic stress disorder (PTSD) symptoms, and complex PTSD among health care professionals, and identifying their predictors.

METHODS

A mixed methods design, including a survey among 196 midwives and gynecologists assessing burnout, intentions to leave, exposure to negative work experiences and PTSD, as well as 15 semi-structured interviews.

DISCUSSION

Most participants experienced multiple difficult events in the delivery room, reporting insufficient emotional support. Burnout and lack of emotional support were significant predictors of PTSD symptoms. Participants expressed a need for emotional support to cope with complex situations.

CONCLUSION

Burnout among midwives must be addressed through prevention and intervention programs. Emotional support is essential in mitigating PTSD symptoms among midwives and gynecologists, enhancing their resilience and well-being.

Measuring post-traumatic stress disorder and complex post-traumatic stress disorder using the International Trauma Questionnaire: results from a Hungarian clinical and non-clinical sample

Background: The 11th revision of the International Classification of Diseases (ICD-11) simplified the description of post-traumatic stress disorder (PTSD) and also introduced a new trauma-related diagnosis called complex post-traumatic stress disorder (CPTSD). CPTSD is linked to earlier, prolonged interpersonal trauma, and is characterized by a broader range of symptoms, in addition to the core PTSD symptoms. The International Trauma Questionnaire (ITQ) has been developed to assess the new diagnostic criteria.Objectives: The primary aim of our study was to test the factor structure of the ITQ in a clinical and a non-clinical Hungarian sample. We also examined whether the degree of traumatization or the type of trauma experienced was associated with meeting the criteria for PTSD or CPTSD, or with the severity of PTSD or disturbances in self-organization (DSO) symptoms, in both samples.Method: A trauma-exposed heterogeneous clinical sample (N = 176) and a non-clinical sample (N = 229) filled out the ITQ and a modified version of the Life Events Checklist (LEC-5). The factor structure of the ITQ was tested by examining the model fit of seven competing confirmatory factor analysis models.Results: A two-factor second-order model with a second-order PTSD factor (measured by three first-order factors) and a DSO factor (measured directly by six symptoms) had the best fit to the data in both samples if an error correlation was allowed between negative self-concept items. Those in the clinical group who reported more interpersonal and childhood trauma experienced more PTSD and DSO symptoms. Also, there were significant, positive, and weak associations between the total number of different traumas and PTSD and DSO factor scores in both samples.Conclusion: ITQ was found to be a reliable tool to differentiate between PTSD and CPTSD, two related but distinct constructs in a clinical and a non-clinical trauma-exposed sample in Hungary.

Symptom structure of complex posttraumatic stress disorder among Chinese young adults with childhood trauma: a network analysis

BACKGROUND

The 11th revision of the World Health Organization's International Classification of Diseases (ICD-11) includes a new disorder, complex posttraumatic stress disorder (CPTSD), the diagnostic applicability of which has not been discussed sufficiently in Chinese culture. The network approach to psychopathology enables investigation of the structure of disorders at the symptom level, which allows for analysis of direct symptom interactions. The main objectives of the present study were to explore CPTSD symptom structure and identify key symptoms in CPTSD among young adults in China.

METHODS

The present study collected a large, stratified sample of Beijing university students (1368), ranging from 18 to 25 years old, the majority of whom (65.4%) were female. CPTSD symptoms were assessed using the International Trauma Questionnaire (ITQ). A regularized partial correlation network and Bayesian network were applied to estimate the network structure and the upstream symptoms of CPTSD, respectively.

RESULTS

The regularized partial correlation network showed that the high central symptoms were feelings of failure and hypervigilance, while the bridge symptom between posttraumatic stress disorder (PTSD) and disturbance in self-organization (DSO) domains was long-term upset. The Bayesian network showed that external avoidance and hypervigilance symptoms were upstream in CPTSD symptoms.

CONCLUSIONS

Hypervigilance is a central symptom that can be predictive of other symptoms of CPTSD. While feeling of failure is also a highly central symptom, it may be influenced by other symptoms. In the diagnosis and intervention of CPTSD, more attention should be given to hypervigilance symptoms.

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.

Mapping the availability of translated versions of posttraumatic stress disorder screening questionnaires for adults: A scoping review

Background: The most used questionnaires for PTSD screening in adults were developed in English. Although many of these questionnaires were translated into other languages, the procedures used to translate them and to evaluate their reliability and validity have not been consistently documented. This comprehensive scoping review aimed to compile the currently available translated and evaluated questionnaires used for PTSD screening, and highlight important gaps in the literature.Objective: This review aimed to map the availability of translated and evaluated screening questionnaires for posttraumatic stress disorder (PTSD) for adults.Methods: All peer-reviewed studies in which a PTSD screening questionnaire for adults was translated, and which reported at least one result of a qualitative and /or quantitative evaluation procedure were included. The literature was searched using Embase, MEDLINE, and APA PsycInfo, citation searches and contributions from study team members. There were no restrictions regarding the target languages of the translations. Data on the translation procedure, the qualitative evaluation, the quantitative evaluation (dimensionality of the questionnaire, reliability, and performance), and open access were extracted.Results: A total of 866 studies were screened, of which 126 were included. Collectively, 128 translations of 12 different questionnaires were found. Out of these, 105 (83.3%) studies used a forward and backward translation procedure, 120 (95.2%) assessed the reliability of the translated questionnaire, 60 (47.6%) the dimensionality, 49 (38.9%) the performance, and 42 (33.3%) used qualitative evaluation procedures. Thirty-four questionnaires (27.0%) were either freely available or accessible on request.Conclusions: The analyses conducted and the description of the methods and results varied substantially, making a quality assessment impractical. Translations into languages spoken in middle- or low-income countries were underrepresented. In addition, only a small proportion of all translated questionnaires were available. Given the need for freely accessible translations, an online repository was developed.HIGHLIGHTS We mapped the availability of translated PTSD screening questionnaires.The quality of the translation and validation processes is very heterogenous.We created a repository for translated, validated PTSD screening questionnaires.

French cross-cultural adaptation and validation of the International Trauma Questionnaire (ITQ) in a French community sample

Aims: In 2018, the 11th version of the International Classification of Diseases (ICD-11) recognized a new diagnosis in addition to Posttraumatic Stress Disorder (PTSD), that of Complex Posttraumatic Stress Disorder (C-PTSD). A new measurement tool was developed to assess both disorders: the International Trauma Questionnaire. The objectives of this study were (a) to conduct a French translation of the tool, (b) to confirm the factorial structure of the tool, (c) to verify its convergent and divergent validity, (d) and finally to ensure its temporal stability.Method: The ITQ was translated into French using a committee approach, bringing together experts and bilingual individuals with a dual French-English culture. It was then completed by 750 people residing in France and having been exposed to potentially traumatic events, recruited from the general population. Other measures were also completed (HADS, ITEM, PCL-5, WHO-5, DERS).Results: Confirmatory factor analysis confirmed that the French version of the ITQ had the same factor structure as the original version. The scale showed satisfactory convergent and divergent validity, as well as good stability over time.Conclusion: Our study suggests that the French version of the ITQ is a good measurement tool for assessing PTSD and C-PTSD according to the ICD-11 diagnostic criteria.HIGHLIGHTS This study provides the first translation and validation of the International Trauma Questionnaire in the French population.Confirmatory factor analysis confirmed that the French version of the ITQ had the same factor structure as the original version.The French version of the ITQ showed good convergent and divergent validity, as well as good test-retest reliability.

Trauma exposure and co-occurring ICD-11 post-traumatic stress disorder and complex post-traumatic stress disorder in adults with lived experience of psychiatric disorder

OBJECTIVE

To establish factors associated with ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) in a large sample of adults with lived experience of psychiatric disorder and examine the psychiatric burden associated with the two disorders.

METHODS

One thousand three hundred and five adults were recruited from the National Centre for Mental Health (NCMH) cohort. ICD-11 PTSD/CPTSD were assessed with the International Trauma Questionnaire (ITQ). Binary logistic regression was used to determine factors associated with both PTSD and CPTSD. One-way between-groups analysis of variance was conducted to examine the burden associated with the two disorders in terms of symptoms of anxiety, depression, and psychological wellbeing. For post-hoc pairwise comparisons, the Tukey HSD test was used, and the magnitude of between-group differences assessed using Cohen's d.

RESULTS

Probable ICD-11 CPTSD was more common than PTSD within the sample (PTSD 2.68%; CPTSD 12.72%). We found evidence that PTSD was associated with interpersonal trauma and household income under £20,000 a year. CPTSD was also associated with interpersonal trauma, higher rates of personality disorder, and lower rates of bipolar disorder. Those with probable-CPTSD had higher levels of current anxiety and depressive symptoms and lower psychological wellbeing in comparison to those with probable-PTSD and those with neither disorder.

CONCLUSIONS

CPTSD was more prevalent than PTSD in our sample of people with lived experience of psychiatric disorder. Our findings indicate a need for routine screening for trauma histories and PTSD/CPTSD in clinical settings and a greater focus on the need for interventions to treat CPTSD.

Chronic Pain Personification Following Child Abuse: The Imprinted Experience of Child Abuse in Later Chronic Pain

Child abuse has been shown to increase the risk for chronic pain. The illness personification theory implies that individuals tend to ascribe humanlike characteristics to chronic pain, and that this personification is embedded in the way they cope with their chronic condition. Recent findings demonstrate that individuals who experienced interpersonal violence tend to personify chronic pain in a way that resonates with past abusive experience. Although findings prevail to the link between trauma and the experience of the body, the personification of chronic pain among individuals who experienced child abuse has not been examined before. This article includes two studies that tested whether child abuse is implicated in abusive chronic pain personification in a young adult female sample (Study 1) and among females who experienced child abuse (Study 2). In both studies, self-report measures of child abuse, posttraumatic stress (PTS) symptoms, complex posttraumatic symptoms (disturbances of self-organization [DSO]), and abusive chronic pain personification were administered. Structural equation modeling was utilized to assess the hypotheses. The findings of the two studies showed a significant association between child abuse and pain personification. Whereas PTS symptoms did not mediate this link (Study 1), DSO symptoms mediated this association (Study 2). The findings of these studies support the understanding that the experience of interpersonal violence is engraved in the experience of the body, as reflected in abusive chronic pain personification. Disturbances in self-organization seem to underlie this process, thus pertaining to the link between the experience of the body, self, and interpersonal trauma.

Russian Version of the International Trauma Questionnaire: Adaptation and Validation in a Non-Clinical Sample

Purpose. The article presents the results of adaptation and validation of the International Trauma Questionnaire (ITQ) on a Russian sample. The questionnaire measures the symptoms of complex post-traumatic stress disorder (CPTSD), which can develop as a result of exposure to prolonged, repetitive traumatic experiences in the interpersonal sphere. Method. The study was carried out on a non-clinical sample, which included 429 participants who were 18 to 68 years old and who experienced at least one traumatic event in their lives. International Trauma Questionnaire (ITQ), LEC-5 (Life events checklist-5), author’s questionnaire “Emotional abuse”, Symptom Checklist (SCL-90-R) were used in the study. Results. The structure of the questionnaire in the Russian-speaking sample confirmed the two-factor model of complex PTSD, which combines the symptoms of PTSD («Re-experiencing», «Avoidance», «Sense of Threat») and disturbances of Self-organization («Affective Dysregulation», «Negative Self-concept», «Disturbances in Relationships»). Internal consistency of the scale was in the acceptable range. Among those who have experienced at least one traumatic event, 20% met criteria for PTSD (11%) or CPTSD (9%). These data show that respondents with CPTSD have more intense psychopathological symptoms than respondents with PTSD; women show more intense symptoms of CPTSD than men.

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.

The shielding effect of not responding: Peritraumatic responses to child abuse and their links to posttraumatic symptomatology

BACKGROUND

Extensive literature focuses on peritraumatic responses to trauma and their link to subsequent posttraumatic symptomatology. However, although posttraumatic symptomatology following child abuse (CA) has been documented, research on peritraumatic responses to CA is sparse.

OBJECTIVE

The current study utilizes a new typology of peritraumatic responses to CA and tests whether automatic and behavioral peritraumatic responses to CA differ in their long-term implications for posttraumatic symptomatology, i.e., posttraumatic stress (PTS symptoms), deficiency in self-organization (DSO symptoms; complex posttraumatic symptoms), and dissociation.

PARTICIPANTS, SETTINGS AND METHODS

One-hundred and eighty adult CA survivors reported on CA, peritraumatic responses, PTS symptoms, DSO symptoms, and dissociation.

RESULTS

The tendency to freeze and dissociate, and utilize extensive behavioral methods to survive the abuse were implicated in higher posttraumatic symptomatology (F(2,178) > 4.26, p < 0.01). The absence of automatic and behavioral responses were found to be implicated in the lowest levels of posttraumatic symptomatology (p < 0.01) and to buffer the effect of CA severity on PTS and DSO posttraumatic symptoms (0.047 > effect>0.029, p < 0.001).

CONCLUSIONS

The findings uncovered a novel response pattern, reflected in a tendency to eradicate responses to CA, which was the most protective in regard to its link to later posttraumatic symptomatology. Contrarily, the most scarring peritraumatic responses to CA that arose from the findings were the tendency to freeze and dissociate and utilize various excessive behavioral methods to endure the abuse. These findings imply that CA generates several possible responses, some of which, although allowing for survival in childhood, have adverse effects in adulthood.

Examining the factor structure of ICD-11 posttraumatic stress disorder (PTSD) and complex-PTSD among prison staff exposed to potentially traumatic experiences

The recently released 11th edition of the International Classification of Diseases (ICD-11) classifies posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as distinct, yet related, disorders within the spectrum of trauma and stress-related disorders. This study aimed to explore the construct validity of the International Trauma Questionnaire (ITQ), a measure of ICD-11 PTSD and CPTSD symptoms among prison governors (i.e., wardens in the U.S. and Canada). Trauma-exposed prison governors (N = 409) aged 26 to 82 years (M = 50.04, SD = 7.97) provided their data online anonymously. Confirmatory factor analyses were performed to evaluate the construct validity of ITQ scores. When using the five-point item response scale, our five first-order factor model produced the best fit to the data; however, when using a dichotomous item scale, the first-order two-factor PTSD and disturbances of self-organization (DSO) model produced the best fit to the data. These results indicate that item-coding and estimation methods can significantly impact conclusions about the best-fitting model for this measure among trauma-exposed prison governors.

Complex PTSD and borderline personality disorder

BACKGROUND

This article builds on a previous review (Ford and Courtois, Borderline Personal Disord Emot Dysregul 1:9, 2014) which concluded that complex posttraumatic stress disorder (cPTSD) could not be conceptualized as a sub-type of either PTSD or BPD. Recent research is reviewed that extends and clarifies the still nascent understanding of the relationship between cPTSD and BPD.

MAIN BODY

The circumscribed formulation of adult cPTSD that has been developed, validated, and included in the 11th Edition of the International Classification of Diseases has spurred research aimed at differentiating cPTSD and BPD both descriptively and empirically. A newly validated Developmental Trauma Disorder (DTD) syndrome for children and adolescents provides a basis for systematic research on the developmental course and origins of adult cPTSD and BPD. This review summarizes recent empirical findings regarding BPD, PTSD, and cPTSD in terms of: (1) prevalence and comorbidity; (2) clinical phenomenology; (3) traumatic antecedents; (4) psychobiology; (5) emotion dysregulation; (6) dissociation; and (7) empirically supported approaches to clinical assessment and psychotherapeutic treatment.

CONCLUSION

The evidence suggests that PTSD, cPTSD, and BPD are potentially comorbid but distinct syndromes. A hypothesis is advanced to stimulate scientific research and clinical innovation defining and differentiating the disorders, positing that they may represent a continuum paralleling the classic conceptualization of the stress response, with dissociation potentially involved in each disorder.

Correlations Between Cognitive Functions and Clinical Symptoms in Adolescents With Complex Post-traumatic Stress Disorder

Introduction: Complex post-traumatic stress disorder (C-PTSD) is characterized by the typical symptoms of PTSD, in addition to affective dysregulation, negative self-concept, and disturbances in interpersonal relationships. Children and adolescents with C-PTSD have been reported to have deficits in emotional and cognitive functions. We hypothesized that the following are associated with the severity of C-PTSD symptoms: (1) adolescents with C-PTSD who show deficits in emotional perception and cognitive functions, including executive function and attention; and (2) deficits in neurocognitive functions. Methods: Information on 69 adolescents with PTSD, aged 10-19 years, was gathered from seven shelters. All participants were assessed using complete clinical scales, including the C-PTSD Interview and Depression, Anxiety, and Stress Scales, and neurocognitive function tests, including the emotional perception, mental rotation, and modified Tower of London tests. Results: Adolescents with C-PTSD were more likely to have a history of sexual assault, dissociation, and self-harm than those with PTSD. The total and subscale scores of the C-PTSD Interview Scale in adolescents with C-PTSD were higher than that in adolescents with PTSD. In addition, neurocognitive functions, including emotional perception, attention, and working memory, were correlated with the severity of C-PTSD symptoms. Discussion: Adolescents with C-PTSD experienced more serious clinical symptoms and showed more deficits in neurocognitive functions than adolescents with PTSD. Clinicians should pay careful attention toward the emotional and neurocognitive functions when assessing and treating patients with C-PTSD.

A systematic literature review of factor analytic and mixture models of ICD-11 PTSD and CPTSD using the International Trauma Questionnaire

The 11th version of the International Classification of Diseases (ICD-11; WHO, 2018) describes two distinct trauma related disorders, Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD). This review aims to summarise and synthesize evidence from factor analytic and mixture modelling studies that have investigated the latent structure of the International Trauma Questionnaire. A systematic search of PsycInfo, Web of Science, Scopus and Pubmed databases was conducted to identify relevant articles. Thirty-three studies met the inclusion criteria for this systematic review. The latent structure of the ITQ was best represented by two models; a correlated six-factor model (Re-experiencing, Avoidance, Threat, Affect Dysregulation, Negative Self Concept, and Disturbed Relationships) and a two-factor second-order model (PTSD and Disturbances in Self-Organization). Mixture model studies consistently identified distinct classes representing those displaying PTSD and CPTSD symptoms. Numerous studies demonstrated support for the factorial and discriminant validity of PTSD and CPTSD when analysed in conjunction with other variables. Overall, support was found for the conceptual coherence of PTSD and CPTSD as empirically distinguishable disorders, as measured by the ITQ. The available evidence demonstrates that the ITQ is a valid measure of ICD-11 PTSD and CPTSD. Recommendations for future research are included.

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.

Complex PTSD in survivors of intimate partner violence: risk factors related to symptoms and diagnoses

BACKGROUND

In 2018, the World Health Organization proposed a new diagnosis entitled Complex Posttraumatic Stress Disorder (CPTSD) in the ICD-11. It is a diagnosis that encompasses the classic symptoms of PTSD, along with symptoms of disturbances in self-organization (DSO). Although this disorder has been studied in several countries and populations, research on the population of women survivors of intimate partner violence (IPV) is scarce.

OBJECTIVES

1) To analyse the prevalence of CPTSD and PTSD according to ICD-11 criteria; 2) To analyse the associations between CPTSD symptomatology and severity of violence, level of fear, resilience and strategies of emotion regulation; 3) To analyse which risk factors (severity of violence, level of fear, resilience and strategies of emotion regulation) may differ between female survivors with CPTSD or PTSD.

METHOD

162 women IPV survivors who completed a socio-demographic and violence-related interview, as well as questionnaires to assess PTSD and CPTSD, severity of violence, resilience and emotion regulation strategies.

RESULTS

The results showed a higher prevalence of CPTSD (39.50%), compared to PTSD (17.90%). Moreover, a high level of fear was related to re-experiencing in the here and now, avoidance, current sense of threat and disturbances in relationships. Low levels of resilience and maladaptive emotion regulation strategies such as expressive suppression were related to affective dysregulation, negative self-concept and disturbances in relationships. Finally, the results showed that maladaptive emotion regulation strategies differentiated between meeting CPTSD and PTSD criteria in women survivors of IPV.

CONCLUSION

The findings of this study indicated that CPTSD was twice as prevalent as PTSD within the sample. Moreover, maladaptive emotion regulation strategy as expressive suppression was the main variable related to experiencing CPTSD, in contrast to PTSD. These findings may have important implications for the design of specific treatments aimed at women survivors of IPV, who also suffer CPTSD.

Factor structure of the International Trauma Questionnaire in UK Armed Forces veterans residing in Northern Ireland

Background: Complex Posttraumatic Stress Disorder (C-PTSD) was recently included in the revised International Classification of Diseases (ICD-11) by the World Health Organization (WHO, 2018). C-PTSD is a new trauma related disorder which may develop after prolonged and multiple exposures to trauma. It is a sister disorder of PTSD and is further characterized by symptomatology of disorganized self-organization (DSO). To qualify for the diagnosis, individuals must first meet the diagnostic criteria for PTSD, then report DSO symptoms and functional impairment. A body of work is emerging which has focused on the underlying dimensionality of C-PTSD across both adult and more recently adolescent populations from differing index trauma groups and from across several nations and cultures. However, few studies have been conducted in populations exposed to combat trauma despite the obvious prolonged and multiple nature of their trauma histories. Objective: To contribute to emerging evidence of the factor structure of ICD-11 C-PTSD in a novel population. Methods: This is the first factor analytic study to explore C-PTSD in a sample of UK Armed Forces veterans residing in Northern Ireland (N = 732). C-PTSD was measured via the ITQ and we utilized CFA to assess the fit of 7 competing models. Results: Based on established CFA fit indices, a correlated, first order, 6-factor model of C-PTSD, representing 3 PTSD and 3 DSO symptom groupings, was deemed to provide superior fit to the data compared to 6 alternative C-PTSD models. The superiority of the model was further supported by statistical comparisons of competing C-PTSD models. All factor loadings (0.866-0.998) and inter-factor correlations (.746-.975) of the optimally fitting model were statistically significant and high. Conclusion: These results provide support for the construct validity of ICD-11 C-PTSD in a unique sample of Armed Forces veterans residing in Northern Ireland.

Revealing what is distinct by recognising what is common: distinguishing between complex PTSD and Borderline Personality Disorder symptoms using bifactor modelling

Background: Despite concerns of conceptual similarity, increasing evidence supports the discriminant validity of Complex Posttraumatic Stress Disorder (CPTSD) and Borderline Personality Disorder (BPD). However, all studies to date have assumed a categorical model of psychopathology. In contrast, dimensional models of psychopathology, such as the Hierarchical Taxonomy of Psychopathology model (i.e. HiTOP model), recognise shared vulnerability across supposedly discrete disorders. Accounting for shared vulnerability between CPTSD and BPD symptoms may help to better reveal what is unique about these constructs. Objective: To identify the distinct and shared features of CPTSD and BPD via the application of dimensional modelling procedures. Method: Confirmatory bifactor and confirmatory factor analysis were employed to identify the optimal latent structure of CPTSD and BPD symptoms amongst a convenience sample of Israeli adults (N = 617). Additionally, structural equation modelling was used to identify risk factors associated with these constructs. Results: The latent structure of CPTSD and BPD symptoms was best explained by a bifactor model including one 'general' factor (i.e. vulnerability to all symptoms) and three 'specific' correlated factors (i.e. vulnerability to PTSD, DSO, and BPD symptoms, respectively). CPTSD symptoms were more readily distinguished from the general factor whereas BPD symptoms were not as easily distinguished from the general factor. CPTSD symptoms reflecting a negative self-concept and BPD symptoms reflecting an alternating self-concept were the most distinctive features of CPTSD and BPD relative to the general factor, respectively. Most of the risk factors were associated with the general vulnerability factor, consistent with the predictions of dimensional models of psychopathology regarding shared risk across supposedly distinct psychiatric constructs. Conclusion: Consistent with a dimensional model of psychopathology, CPTSD and BPD shared a common latent structure but were still distinguishable. CPTSD and BPD symptoms may be most effectively distinguished based on the phenomenology of self-concept symptoms.

COVID-19-related fear and stress among individuals who experienced child abuse: The mediating effect of complex posttraumatic stress disorder

BACKGROUND

The COVID-19 pandemic exposes individuals not only to health-related risks, but also to psychosocial fear and acute stress. Previous studies reveal that individuals who experienced child abuse (CA), especially those who suffer from complex posttraumatic stress disorder (CPTSD), are at a higher risk of reacting with fear and stress when faced with stressful life-events.

OBJECTIVE

To test whether exposure to CA is implicated in a higher risk of COVID-19-related fear and acute stress, and whether CPTSD intervenes in such processes.

PARTICIPANTS AND SETTINGS

A convenience sample of 837 adults participated in the study during the first peak of COVID-19 in Israel.

METHODS

Participants completed self-report questionnaires, assessing child physical, sexual and emotional abuse, CPTSD (ITQ), COVID-19-related acute stress disorder (COVID-19 ASD; ASDS) and fear of COVID-19.

RESULTS

Bivariate analyses showed that participants who experienced CA were higher than participants who did not experience CA in COVID-19 ASD (p = .032), but not in fear of COVID-19 (p = .65). Mediation analyses demonstrated two significant paths: in the first, CA was associated with elevated fear of COVID-19 (effect = .061, .059; p < 0.05) and COVID-19 ASD (effect = .14, .084; p < 0.05) through the mediation of CPTSD; in the second path, when controlling for the mediation of CPTSD, CA was associated with reduced fear of COVID-19 (effect = -.15; p = 0.001), and COVID-19 ASD (effect = -.12; p = 0.024).

CONCLUSIONS

The findings reveal a complex pattern, indicating that CPTSD may be a risk factor for elevated levels of COVID-19 distress among individuals who experienced CA. However, some CA survivors may express reduced COVID-19 distress.

Indirect effects of PTSD and complex PTSD in the relationship of polyvictimization with intimate partner violence victimization and perpetration among men in mandated treatment

Background: Polyvictimization is associated with posttraumatic stress disorder (PTSD), severe impairment, and re-victimization, including due to intimate partner violence (IPV), but polyvictmization's role in the perpetration of IPV is less clear. Objective: To examine the indirect effect of PTSD and complex PTSD in the relationship between polyvictimization and IPV perpetration. Method: Polyvictims were identified by cluster analysis of self-reported lifetime victimization history data in a random national sample (N = 234) of men at 66 clinical treatment centers for domestic violence perpetrators in Israel. Results: Four sub-groups were identified: low exposure to abuse and physical neglect (C1, N = 105), and three polyvictim sub-groups characterized by multiple forms of past exposure to neglect and verbal abuse (C2, N = 38), to verbal and physical abuse without neglect (C3, N = 46), or to neglect and both verbal and physical abuse (C4, N = 28). Participants also were characterized as having low exposure to traumatic events across the lifespan (cluster L5, N=156), or high exposure to traumatic events across the lifespan (cluster L6, N=78). Complex PTSD symptoms had an indirect effect in the relationship between membership in the C3 and C4 polyvictimization clusters (β=.45, p<.05, β=.60, p<.05; respectively) and severity of psychological IPV victimization, as well as between C3 polyvictimization cluster membership and severity of psychological IPV perpetration (β=.32, p<.05). In contrast, PTSD symptoms had no indirect effect in any relationship between cluster membership and IPV outcomes. High lifetime trauma exposure also was directly associated with sexual IPV victimization. Conclusions: Complex PTSD may be a mechanism linking polyvictimization to the severity of both IPV victimization and perpetration. Clinical implications are discussed.

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.

"My own flesh and blood": The implications of child maltreatment for the orientation towards the body among dyads of mothers and daughters

BACKGROUND

Orientation to bodily signals reflects the ways in which individuals interpret their bodily sensations. Such orientation is formed within early interpersonal context. Findings reveal that trauma may result in catastrophic and fearful orientation towards bodily signals. However, not much is known regarding the link between trauma and orientation towards the body as manifested within a family intergenerational context.

OBJECTIVE

This study examines the link between child maltreatment, complex posttraumatic stress symptoms (CPTS symptoms), and a posttraumatic orientation to bodily signals among dyads of mothers and their young adult daughters.

PARTICIPANTS AND SETTING

194 mother-daughter dyads (mothers' mean age = 56, SD = 6.3; daughters' mean age = 26, SD = 3.03) completed self-reported questionnaires, assessing child maltreatment (CTQ), CPTS symptoms (ITQ), and orientation to bodily signals (pain catastrophizing, anxiety sensitivity-physical, body vigilance).

RESULTS

Orientation to bodily signals was associated with child maltreatment, through the mediation of CPTS symptoms among mothers (indirect effects between 0.13-0.28; p > 0.021) and daughters (indirect effects between 0.21-0.11; p > 0.032). Mothers' child maltreatment was associated with daughters' child maltreatment (effect = 0.35; p < 0.001), and mothers' orientation to bodily signals was associated with daughters' orientation (effects between 0.19-0.27; p < 0.016). Daughters' orientation to bodily signals was partially associated with mothers' child maltreatment through mothers' CPTS symptoms and orientation to body (indirect effect = 0.064; p = 0.023).

CONCLUSIONS

Child maltreatment is implicated in posttraumatic orientation towards bodily signals. Such secondary processes may be intergenerationally transmitted.

Complex PTSD among treatment-seeking veterans with PTSD

Background: In the ICD-11 hierarchical classification structure, posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) are separate and distinct but also 'sibling' disorders, meaning that the diagnoses follow from the parent category of traumatic stress disorders. Objective: The aim of this study was to examine the prevalence of CPTSD in treatment-seeking war veterans with PTSD more than 20 years after the exposure to cumulative war-related trauma(s). The second aim was to examine if there was an association between demographic and psychosocial variables and CPTSD or PTSD. Method: A sample of 160 male war veterans with PTSD referred to the outpatient service of the PTSD Referral Centre at the Clinical Hospital Centre (CHC) Rijeka participated in a cross-sectional study. Psychiatric comorbidity was assessed using the Mini-International Neuropsychiatric Interview (MINI) and participants completed validated self-report measures: The Life Events Checklist for DSM-5 (LEC-5), International Trauma Questionnaire (ITQ). Results: In total, 80.63% of the sample met criteria for a probable diagnosis of CPTSD. The study revealed that there was no significant difference in the length of deployment, in the intensity of the PTSD symptoms, types of trauma exposure and pharmacotherapeutic treatment between PTSD and CPTSD group. It was found that veterans with PTSD were more likely to be divorced and to participate in PTSD clubs. On the other hand, veterans with CPTSD were significantly more likely to have higher levels of functional impairment and comorbidity with general anxiety disorder (GAD) compared to the PTSD group. Conclusions: This study supports the proposition that a prolonged trauma of severe interpersonal intensity such as war is related to high rates of CPTSD among treatment-seeking veterans, years after the war. The distinction between PTSD and complex PTSD may help the selection of person-centred treatment interventions that would target specific mental health and functional problems in patients.

Examining the boundaries between ICD-11 PTSD/CPTSD and depression and anxiety symptoms: A network analysis perspective

BACKGROUND

Two newly identified sibling disorders - ICD-11 PTSD and CPTSD - have been well validated in the last few years. Although these trauma-related disorders are suggested to be neatly separated from depression and anxiety, no study has used a network analysis to examine those definitions' construct validity when they also interplay with symptoms of depression and anxiety. Additionally, no research has focused upon the specific boundaries between these four disorders' symptoms, the bridges between them, and the ways they influence each other among clinical populations.

METHODS

A sample of 234 men drawn randomly from a national sample of 1,600 Jewish men receiving treatment for domestic violence in Israel completed the ICD-11 International Trauma Questionnaire (ITQ) and Brief Symptom Inventory (BSI).

RESULTS

The ICD-11 CPTSD, depression and anxiety clustering network results revealed, within the EGA, a four-cluster solution in which PTSD and CPTSD symptoms are differentiated from two other distinct clusters of anxiety and depression symptoms. Feelings of worthlessness and avoiding internal reminders of the experience were the most central symptoms.

LIMITATIONS

Due to the use of a cross-sectional design, causal interpretation of the network correlation between symptoms should be made cautiously.

CONCLUSIONS

These findings strengthen the approach that ICD-11 PTSD and CPTSD have a distinct construct; however, they also reflect a strong positive connection to anxiety and depression symptoms and no clear boundaries between disorders. Specifically, dysphoria/avoidance-related symptoms act as a bridge between the disorders, which may be important targets for specific assessments and related interventions.

New findings questioning the construct validity of complex posttraumatic stress disorder (cPTSD): let's take a closer look

This commentary provides a broader context for interpreting evidence from Latent Class and Latent Profile analyses on complex posttraumatic stress disorder (CPTSD) that was provided in a recent contribution to the European Journal of Psychotraumatology. These data analytic strategies are not alone sufficient to test the construct validity of CPTSD. They base their conclusion on the empirical finding of substantial variation in latent models obtained with different analytic procedures and interpretations of the fit of different latent models, as well as interesting additional evidence of dispersion when individual patients' symptom counts and symptom severity scores on PTSD and CPTSD are examined. However, the results of their analyses actually do provide support for one feature of construct validity, demonstrating discriminant validity by showing a consistent differentiation between PTSD and CPTSD (with expectable variation in both PTSD and CPTSD severity level by persons). Even in a sample of patients diagnosed with PTSD, there may be a Disorders of Self Organization (DSO) sub-group with low PTSD symptom severity. More detailed examination of which DSO symptoms and sub-domains characterize the DSO sub-group and the CPTSD sub-group is needed in order to clarify the nature of the DSO/CPTSD construct. Other analyses needed to fully test construct validity also are described.

The role of complex posttraumatic stress symptoms in the association between exposure to traumatic events and severity of intimate partner violence

BACKGROUND

Symptoms of both posttraumatic stress disorder (PTSD) and disturbances in self-organization (DSO) have been suggested to play a role in the association between an individual's childhood physical abuse and neglect and his/her perpetration of IPV in adulthood; however, the two have yet to be studied in one model. Thus, we aimed to examine the interrelations among childhood exposure to violence and physical neglect, exposure to trauma across one's lifetime, ICD-11 CPTSD symptoms (i.e., PTSD and DSO), and IPV severity.

METHODS

Participants were 234 men drawn randomly from a national sample of 1600 mandated men receiving treatment for domestic violence in Israel. They completed measures of potentially traumatic exposure, symptoms of CPTSD, child abuse and neglect, and IPV. Structural equation modeling (SEM) was used to examine possible direct and indirect effects of the study variables.

RESULTS

Results confirmed the indirect role of CPTSD symptoms in the association between the following types of traumatic exposure - childhood exposure to violence (B = .03, β = .05, SE = .01, p = .05, CI 90% [.041, .143]), childhood exposure to physical neglect (B = .04, β = .04, SE = .02, p < .01, CI 90% [.014, .092]), and lifetime exposure to potentially traumatic events, or PTEs (B = .04, β = .09, SE = .01, p < .001, CI 90% [.006, .074]) - and the perpetration of psychological IPV as an adult. No significant results were found in relation to the perpetration of physical IPV.

CONCLUSIONS

The current cross-sectional study findings suggest a preliminary direction regarding the possible direct and indirect effects of ICD-11CPTSD on the severity of IPV psychological perpetration. The clinical implications include the need to focus on both PTSD and DSO symptoms in order to help reduce these potential risk factors for psychological IPV perpetration.

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.

The replicability of ICD-11 complex post-traumatic stress disorder symptom networks in adults

BACKGROUND

The ICD-11 includes a new disorder, complex post-traumatic stress disorder (CPTSD). A network approach to CPTSD will enable investigation of the structure of the disorder at the symptom level, which may inform the development of treatments that target specific symptoms to accelerate clinical outcomes.AimsWe aimed to test whether similar networks of ICD-11 CPTSD replicate across culturally different samples and to investigate possible differences, using a network analysis.

METHOD

We investigated the network models of four nationally representative, community-based cross-sectional samples drawn from Germany, Israel, the UK, and the USA (total N = 6417). CPTSD symptoms were assessed with the International Trauma Questionnaire in all samples. Only those participants who reported significant functional impairment by CPTSD symptoms were included (N = 1591 included in analysis; mean age 43.55 years, s.d. 15.10, range 14-99, 67.7% women). Regularised partial correlation networks were estimated for each sample and the resulting networks were compared.

RESULTS

Despite differences in traumatic experiences, symptom severity and symptom profiles, the networks were very similar across the four countries. The symptoms within dimensions were strongly associated with each other in all networks, except for the two symptom indicators assessing aspects of affective dysregulation. The most central symptoms were 'feelings of worthlessness' and 'exaggerated startle response'.

CONCLUSIONS

The structure of CPTSD symptoms appears very similar across countries. Addressing symptoms with the strongest associations in the network, such as negative self-worth and startle reactivity, will likely result in rapid treatment response.Declaration of interestA.M. and M.C. were members of the World Health Organization (WHO) ICD-11 Working Group on the Classification of Disorders Specifically Associated with Stress, reporting to the WHO International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders.

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.

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.

Trial registration

Ethical approval was obtained from the Swiss Cantonal Ethic Commission (Nr 201,500,096). This research was also registered at the World Health Organization Clinical Trials Search Portal through the German Clinical Trial Register, Trial DRKS00012268.
