Risk factors and comorbidity of ICD-11 PTSD and complex PTSD: Findings from a trauma-exposed population based sample of adults in the United Kingdom

Do psychological treatments for PTSD in children and young people reduce trauma-related appraisals? A systematic review and meta-analysis

Research is increasingly highlighting the role of negative trauma-related appraisals in child and adolescent post-traumatic stress disorder (PTSD). The cognitive model of PTSD claims that an essential mechanism of treatment is a reduction in these appraisals. The current systematic review with meta-analysis investigated the extent to which psychological treatments for PTSD reduce negative trauma-related appraisals in children and adolescents. Four databases (PsycINFO, Medline Complete, CINAHL Complete and PTSDpubs) were searched on the 11-12th December 2022. The Risk of Bias 2 (ROB-2) tool was used to assess for risk of bias. Thirteen studies were included in this review, comprising 937 child and adolescent participants. Using a random effects model to perform the meta-analysis, a medium pooled effect size for the effect of current treatments on trauma-related appraisals was found (g = -.67, 95% CI [-.86, -.48]). There was only a moderate level of heterogeneity between studies (I2 = 44.4%), increasing the confidence with which these findings can be interpreted. These results indicate that psychological treatments for child and adolescent PTSD significantly reduce negative trauma-related appraisals. However, it is important to note that no trial included in the review was categorised as having low risk of bias.

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.

Use of renin-angiotensin system blockers and posttraumatic stress disorder risk in the UK Biobank: a retrospective cohort study

BACKGROUND

Previous research has shown that the use of renin-angiotensin system (RAS) blockers is linked to a lower prevalence of posttraumatic stress disorder (PTSD), but longitudinal studies are scarce. We aimed to estimate the association between the use of RAS blockers and the risk of PTSD among individuals taking antihypertensive medications.

METHODS

This longitudinal study included participants aged 40-69 from the UK Biobank. Exposure data were obtained from the initial assessment (2006-10), while outcome data were obtained from the online mental health questionnaire administered 6-11 years later (2016-17). We included participants who were under antihypertensive treatment and did not have a prior diagnosis of PTSD before the initial assessment. Use of RAS blockers was defined as self-reported regular use, at the initial assessment, of angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB). Among participants who experienced adverse life experiences, cases of probable PTSD were defined with the six-item PTSD Checklist-Civilian version score ≥ 14. Logistic regression with inverse probability of treatment weighting was used to estimate the odds ratios (ORs) and 95% confidence interval (CI) for the association between RAS blocker use and the risk of probable PTSD.

RESULTS

Of the 15,954 participants (mean age = 59.9 years; 42.6% women) under antihypertensive treatment with no prior history of PTSD at the initial assessment, 64.5% were taking RAS blockers. After a mean follow-up of 7.5 years, 1,249 (7.8%) were newly identified with probable PTSD. RAS blocker users had a lower risk of probable PTSD than RAS blocker non-users (OR = 0.84 [95% CI: 0.75-0.94]), whereas the use of other antihypertensive medications showed no such association (users vs. non-users; calcium channel blockers, OR = 0.99 [95% CI: 0.88-1.11]; beta-blockers, 1.20 [1.08-1.34]; and thiazide-related diuretics, 1.15 [1.03-1.29]). The association between probable PTSD risk and the use of ACEi vs. ARB showed no significant difference (p = 0.96).

CONCLUSIONS

Among individuals under antihypertensive treatment, the use of RAS blockers was associated with a decreased risk of probable PTSD. This added benefit of RAS blockers should be considered in the selection of antihypertensive medications.

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.

Early maladaptive schemas mediate the relationship between severe childhood trauma and eating disorder symptoms: evidence from an exploratory study

BACKGROUND

Childhood trauma history has frequently been linked to eating disorders (EDs); nevertheless, the scientific literature calls for extending knowledge regarding mediators between EDs and childhood trauma. This study explored whether ED symptoms and early maladaptive schemas were more severe in ED patients with severe childhood trauma than in ED patients with no/mild childhood trauma and whether early maladaptive schemas mediated the relationship between childhood trauma and ED symptom severity.

METHODS

Data were extracted from the Regional Centre for Eating Disorders registry at the University Hospital of Verona. The extracted data included self-reported data, including the Eating Disorder Inventory-3 score, Young Schema Questionnaire score, Childhood Experience and Experience of Care and Abuse Questionnaire score, and sociodemographic and clinical information on the ED outpatients seeking care. A mediation analysis using the structural equation modeling procedure was conducted.

RESULTS

Forty-two outpatients, 31% of whom exhibited severe childhood trauma, satisfied the criteria for registry data extraction. The severity of ED symptoms, as well as the early maladaptive schemas' scores for emotional deprivation, defectiveness, failure, vulnerability, insufficient self-control, and negativity, were greater in ED outpatients with severe childhood trauma. Furthermore, early maladaptive schemas related to defectiveness, failure, and negativity had a mediating role in the relationship between severe childhood trauma and ED symptom severity.

CONCLUSIONS

This exploratory study provides preliminary evidence about the importance of early maladaptive schemas in the relationship between trauma history and ED psychopathology. In addition, ED symptoms may represent a dysfunctional attempt to avoid unpleasant emotions associated with schema activation. The results support the need to consider early maladaptive schemas in the treatment of traumatized patients with ED symptoms. Study limitations, research and clinical implications are discussed.

An evaluation of survive and thrive: a 10-week group psychoeducational course for adult interpersonal trauma survivors in Scotland

Emerging evidence supports a phased approach to trauma treatment, including manualised group-based interventions, to facilitate symptom reduction resulting from complex trauma sequelae. This study investigates the efficacy of Survive and Thrive, a 10-week group psychoeducational course for adult survivors of interpersonal trauma. Between August 2019 and February 2022, participants were enrolled on the course. The Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) and Difficulties in Emotion Regulation Scale-Short Form (DERS-SF) were administered pre-intervention and immediately post-intervention. In addition, thematic analysis was applied to qualitative feedback. Results revealed significant reductions in CORE-OM and DERS-SF scores post-intervention, with minimal variability in scores attributed to group delivery (either face-to-face or online). The thematic analysis demonstrated that normalising trauma symptoms and providing coping skills positively impacted participants' experiences. At the same time, the breadth and nature of the content were observed to be an occasional barrier to engagement. In summary, this study proposes that group-based psychoeducational interventions are generally effective for those with mild-to-moderate symptoms of complex trauma. However, further evidence is needed to offer more nuanced recommendations for identifying individuals who may benefit the most from these interventions.

Characteristics of complex posttraumatic stress disorder (PTSD) in young people with PTSD following multiple trauma exposure

BACKGROUND

Complex PTSD (CPTSD) is a relatively new diagnosis. The objective of the present study was to investigate how trauma characteristics, comorbid psychopathology and cognitive and social factors experienced by children and adolescents with a posttraumatic stress disorder (PTSD) diagnosis following exposure to multiple traumatic events differs between those who meet the criteria for CPTSD and those who do not.

METHOD

The present research used baseline data from the DECRYPT trial (BMJ Open, 2021, 11, e047600). Participants (n = 120) were aged 8-17 years and had exposure to multiple traumas and a PTSD diagnosis. The data collected comprised self-report and parent/caregiver-report questionnaires and interviews. Three primary analyses were conducted, comparing number of trauma types, prevalence of sexual trauma and prevalence of intrafamilial abuse between the CPTSD and PTSD-only groups. A range of comorbid psychopathology and cognitive and social factors were compared between the groups in an exploratory secondary analysis. All analyses were preregistered.

RESULTS

The CPTSD group (n = 72, 60%) had a significantly higher frequency of sexual trauma than the PTSD-only group (n = 48, 40%). The groups did not significantly differ on number of trauma types or prevalence of intrafamilial abuse. From the secondary analysis, the CPTSD group were found to have significantly higher scores on measures of negative post-traumatic cognitions, depression and panic. These results were replicated in correlation analyses using a continuous measure of CPTSD symptoms.

CONCLUSIONS

A large proportion of youth exposed to multiple traumatic events met criteria for CPTSD. Sexual trauma appears to be related to CPTSD symptoms. Youth with CPTSD appear to have greater severity of comorbid depression and panic symptoms, as well as more negative post-traumatic cognitions. Further investigation could focus on the directionality and mechanisms for these associations.

Prevalence and validity of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD: A population-based survey of Hong Kong adults

The present study aimed to report the prevalence of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) in the general adult Hong Kong population, and examine the validity of the Chinese International Trauma Questionnaire (ITQ). This descriptive cross-sectional population-based telephone survey included a representative sample of 1070 non-institutionalized permanent Hong Kong residents ages 18-64 years. Participants provided responses to the Chinese version of the ITQ, and measures of adverse childhood experiences (ACEs), depression, anxiety, and stress. Based on the diagnostic algorithm of the ITQ, 5.9% of the sample screened positive for either CPTSD or PTSD, with CPTSD (4.2%) being more common that PTSD (1.7%). Results of the confirmatory factor analysis indicated the first-order correlated 6-factor model to be the best fitting solution. Symptom cluster summed scores were all positively and significantly correlated with all criterion variables. This investigation established the prevalence rates of ICD-11 PTSD and CPTSD using a general adult population sample in Hong Kong. The Chinese ITQ demonstrated sound factorial validity and concurrent validity. Future research can further characterize ICD-11 PTSD and CPTSD in subgroups using the Chinese ITQ.

Cognitive flexibility and resilience measured through a residual approach

BACKGROUND AND OBJECTIVES

Resilience refers to the process through which individuals show better outcomes than what would be expected based on the adversity they experienced. Several theories have proposed that variation in resilience is underpinned by cognitive flexibility, however, no study has investigated this using an outcome-based measure of resilience.

DESIGN

We used a residual-based approach to index resilience, which regresses a measure of mental health difficulties onto a measure of adversity experienced. The residuals obtained from this regression constitute how much better or worse someone is functioning relative to what is predicted by the adversity they have experienced.

METHODS

A total of 463 undergraduate participants completed questionnaires of mental health difficulties and adversity, as well as a number-letter task-switching task to assess cognitive flexibility.

RESULTS

Multiple regression analyses showed that better cognitive flexibility was not associated with greater resilience.

CONCLUSIONS

Our findings do not support theoretical models that propose the existence of a relationship between cognitive flexibility and resilience. Future research may serve to refine the residual-based approach to measure resilience, as well as investigate the contribution of "hot" rather than "cold" cognitive flexibility to individual differences in resilience.

Utilization of Mental Health Provision, Epistemic Stance and Comorbid Psychopathology of Individuals with Complex Post-Traumatic Stress Disorders (CPTSD)-Results from a Representative German Observational Study

Background: Complex post-traumatic stress disorder (CPTSD) is a severely debilitating recently added symptom cluster in the International Classification of Diseases (ICD-11). So far, only limited information on mental health treatment-uptake and -satisfaction of individuals with CPTSD is available. The aim of this study is to investigate these aspects in a representative sample of the German general population. Methods: Participants completed the International Trauma Questionnaire (ITQ) to identify participants with CPTSD, as well as questionnaires on mental health treatment uptake and satisfaction, adverse childhood experiences, anxiety, depression, working ability, personality functioning, and epistemic trust. Results: Of the included n = 1918 participants, n = 29 (1.5%) fulfilled the criteria for CPTSD. Participants with CPTSD had received mental health treatment significantly more often than participants with PTSD or depression (65.5% vs. 58.8% vs. 31.6%; p = 0.031) but reported significantly less symptom improvement (52.9% vs. 78.0% vs. 80.0%; p = 0.008). Lower levels of epistemic trust were associated with higher CPTSD symptoms (p < 0.001). Conclusions: Our study shows that while the vast majority of individuals with CPTSD had received mental health treatment, subjective symptom improvement rates are not satisfactory. CPTSD was associated with a broad number of comorbidities and impairments in functioning. Lower levels of epistemic trust may partially explain worse treatment outcomes.

ICD-11 post-traumatic stress disorder and complex post-traumatic stress disorder in mental health support-seeking former-serving Australian defence force veterans

BACKGROUND

ICD-11 complex post-traumatic stress disorder is a more severe condition than post-traumatic stress disorder, and recent studies indicate it is more prevalent among military samples. In this study, we tested the psychometric properties of the International Trauma Questionnaire, assessed the relative prevalence rates of post-traumatic stress disorder and complex post-traumatic stress disorder in the sample population and explored relationships between complex post-traumatic stress disorder and post-traumatic stress disorder and a range of risk factors.

METHODS

Survey participants (N = 189) were mental health support-seeking former-serving veterans of the Australian Defence Force (ADF) recruited from primary care. Confirmatory factor analysis was used to test the factorial validity of the International Trauma Questionnaire.

RESULTS

The latent structure of the International Trauma Questionnaire was best represented by a two-factor second-order model consistent with the ICD-11 model of complex post-traumatic stress disorder. The International Trauma Questionnaire scale scores demonstrated excellent internal reliability. Overall, 9.1% (95% confidence interval = [4.8%, 13.5%]) met diagnostic requirements for post-traumatic stress disorder and an additional 51.4% (95% confidence interval = [44.0%, 58.9%]) met requirements for complex post-traumatic stress disorder. Those meeting diagnostic requirements for complex post-traumatic stress disorder were more likely to have served in the military for 15 years or longer, had a history of more traumatic life events and had the highest levels of depression, anxiety and stress symptoms.

CONCLUSION

The International Trauma Questionnaire can effectively distinguish between post-traumatic stress disorder and complex post-traumatic stress disorder within primary care samples of Australian Defence Force veterans. A significantly greater proportion of Australian Defence Force veterans met criteria for complex post-traumatic stress disorder than post-traumatic stress disorder. Australian military mental health services should adopt the International Trauma Questionnaire to routinely screen for complex post-traumatic stress disorder and develop complex post-traumatic stress disorder specific interventions to promote recovery in Australian Defence Force veterans with complex post-traumatic stress disorder.

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.

Improvements of complex post-traumatic stress disorder symptoms during a multimodal psychodynamic inpatient rehabilitation treatment - results of an observational single-centre pilot study

Background: Complex post-traumatic stress disorder (CPTSD) describes chronic disturbances in self-organization (i.e. affect dysregulation; negative self-concept; severe difficulties in relationships) which are frequently observed in survivors of prolonged, repeated or multiple traumatic stressors. So far, evidence of psychodynamic treatment approaches for CPTSD is scarce.Methods: In this single-centre observational pilot study, symptom change during a 6-week psychodynamic inpatient treatment in a multimodal psychosomatic rehabilitation centre was evaluated using repeated measures analyses of variance (ANOVAs). Patients completed questionnaires on PTSD and CPTSD symptoms (ITQ), anxiety, depression and somatization (BSI-18), functional impairment (WHODAS) and epistemic trust, mistrust and credulity (ETMCQ) before (T1) and at the end of treatment (T2). A hierarchical linear regression analysis was calculated to identify factors associated with improved CPTSD symptoms.Results: A total of n = 50 patients with CPTSD were included in the study, of whom n = 40 (80%) completed treatment. Patients reported a significant reduction of CPTSD symptoms during treatment with a large effect size (-3.9 points; p < .001; η2 = .36), as well as a significant reduction of psychological distress (p < .001; η2 = .55) and functional impairment (p < .001; η2 = .59). At the end of treatment, 41.0% of patients no longer fulfilled the diagnostic criteria for CPTSD. Changes in epistemic stance included improved epistemic trust (β = -.34, p = .026) and decreased epistemic credulity (β = .37, p = .017), which together with lower age (β = .43, p = .012) and lower depression levels at baseline (β = .35, p = .054) were significantly associated with baseline adjusted mean change of CPTSD symptoms during therapy and explained 48% of its variance.Discussion: In our study, patients reported a significant reduction of CPTSD symptoms and comorbid symptoms during a multimodal psychodynamic inpatient rehabilitation treatment. Improved epistemic trust may facilitate the establishment of a trusting therapeutic relationship, thus fostering an environment of openness for knowledge transfer (i.e. social learning) and the exploration of diverse viewpoints and perspectives in the therapeutic process.

Relationship between anxiety sensitivity and post-traumatic stress symptoms in trauma-exposed adults: A meta-analysis

Given the high rate of trauma exposure among the general population, it is important to delineate the risk factors for post-traumatic stress disorder (PTSD). While historically implicated in panic disorder, anxiety sensitivity is increasingly found to play a role in PTSD. The present review investigated the size of the relationship between anxiety sensitivity and PTSD symptoms among trauma exposed adults. A systematic search on multiple electronic databases (PTSDpubs, CINAHL, MEDLINE and PsycINFO) generated a total of 1025 records, among which 52 (n = 15173) met study inclusion criteria and were included in our random effects meta-analysis. Our results indicated a medium effect size (r = .46, 95% CI =.41,.50) for the relationship between anxiety sensitivity and PTSD symptoms. There was significant between-study heterogeneity. Furthermore, sub-group analyses revealed that study design (cross-sectional vs. longitudinal) may significantly moderate the association between anxiety sensitivity and PTSD severity. No moderation effect was found for assessment of PTSD through interview versus questionnaire, interpersonal versus non-interpersonal trauma, or low versus high study quality. Such patterns of results are consistent with cognitive models of PTSD. Clinical implications, strengths and limitations of the review were discussed.

Personality functioning, positive outlook for the future, and simple and complex post-traumatic stress disorder

Posttraumatic Stress Disorder (PTSD) and its complex form (C-PTSD) are psychopathological conditions that are related to several personality traits. In particular, the current study aims to investigate the associations of impairment of personality functioning (IPF) and positive outlook for the future (POF) with PTSD and C-PTSD. A sample of 304 Brazilian adults responded to an online survey. IPF was measured according to the alternative model for personality disorders, POF was operationalized using optimism and hope scales, and PTSD and C-PTSD were measured using the ICD-11 model. Data analysis included correlation, structural equation models, multivariate analysis of variance, and multinomial logistic regression. The results showed that IPF and POF were moderately correlated with PTSD and C-PTSD in positive and negative directions, respectively. IPF and POF were more strongly associated with C-PTSD than PTSD. From the categorical approach to psychopathology, IPF and POF were shown to be associated only with C-PTSD. This is the first study that provides empirical data on the association of IPF and POF with both forms of PTSD. Understanding the associations between pathological and resilient personality domains and PTSD and C-PTSD symptoms can support the development of effective interventions.

How effective are mood stabilizers in treating bipolar patients comorbid with cPTSD? Results from an observational study

BACKGROUND

Multiple traumatic experiences, particularly in childhood, may predict and be a risk factor for the development of complex post-traumatic stress disorder (cPTSD). Unfortunately, individuals with bipolar disorder (BP) are more likely to have suffered traumatic events than the general population. Consequently, cPTSD could be comorbid with BD, and this may negatively affect psychopathological manifestations. To date, no one has explored whether such comorbidity also affects the response to treatment with mood stabilizers in BD patients.

RESULTS

Here, a cross-sectional study was carried out by comparing the response to treatment, measured by the Alda scale, in a cohort of 344 patients diagnosed with BD type I and II, screened for the presence (or absence) of cPTSD using the International Trauma Questionnaire. The main result that emerged from the present study is the poorer response to mood stabilizers in BD patients with comorbid cPTSD compared with BD patients without cPTSD.

CONCLUSIONS

The results collected suggest the need for an add-on therapy focused on trauma in BD patients. This could represent an area of future interest in clinical research, capable of leading to more precise and quicker diagnoses as well as suggesting better tailored and more effective treatments.

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.

The International Grief Questionnaire (IGQ): A new measure of ICD-11 prolonged grief disorder

Prolonged grief disorder (PGD) is included in the 11th version of the International Statistical Classification of Diseases and Related Health Problems (ICD-11). This study sought to test the validity and reliability of a new brief measure to screen for ICD-11 PGD-the International Grief Questionnaire (IGQ). The psychometric properties of the IGQ were tested using data collected from two bereaved samples of adults from the United Kingdom (n = 1,012) and Ireland (n = 1,011). Confirmatory factor analysis demonstrated that a correlated two-factor model best captured the latent dimensionality of the IGQ in both samples. Estimates of internal reliability were high, whereas the convergent and concurrent validity of the scale were supported through strong associations with external measures. Measurement invariance and differential item functioning testing showed no statistically significant difference in the latent structure of the IGQ nor the functioning of the IGQ items by age, sex, and nationality. For participants who were bereaved for more than 6 months, the rates of probable PGD derived from the IGQ were 10.9% and 15.3% for the Irish and U.K. samples, respectively. The IGQ is a brief, easy-to-use, self-report screening measure that captures all diagnostic criteria of PGD set forth in the ICD-11. Findings from this study provide initial support for the validity, measurement invariance, and reliability of the IGQ among two national samples.

Predictors and (in-)stability of ICD-11 complex posttraumatic stress disorder in older adults: findings from a longitudinal study in Switzerland

Objective: There is a lack of research on complex post-traumatic stress disorder (CPTSD) in older individuals, with little known about the temporal course of CPTSD. Therefore, this study assessed and compared the demographic characteristics, adverse childhood experiences (ACE), and well-being of Swiss older adults with and without probable CPTSD. The (in-)stability of probable CPTSD was also examined in relation to the predictive value of various emotion-related factors.Methods: A longitudinal study was conducted in Switzerland with N = 213 participants (Mage = 69.98 years, SD = 10.61; 45.5% female). Data was collected via face-to-face assessments at baseline and follow-up, 21 months apart. The German version of the International Trauma Questionnaire was used to screen for (C)PTSD. Standardized instruments were used to assess ACE as well as the predictors anger, embitterment, emotion regulation, and meaning in life.Results: From the total sample, n = 16 participants (7.5%) were identified as having probable CPTSD, with only five of these (31.25%) having probable CPTSD at both baseline and follow-up. Individuals with and without probable CPTSD differed significantly regarding age and employment status. Significant predictors of probable CPTSD were anger (β = 0.16), embitterment (β = 0.06), cognitive reappraisal (β = -0.41), and the presence of meaning in life (β = -0.10).Conclusions: Probable CPTSD appears to be relatively unstable over the course of a 21-month period in older individuals. The links between CPTSD and emotion-related predictors highlight potential targets for intervention.

Esketamine-induced post-traumatic stress disorder flashbacks during treatment-resistant depression indication: is it just a side effect?

Background

Posttraumatic stress disorder (PTSD) is a severe and frequent affection that is highly comorbid to major depressive disorder. Comorbid PTSD and depression are usually treatment-resistant, with a high risk of functional impairment and suicide. Esketamine nasal spray is a recent validated treatment for treatment-resistant depression (TRD), but its efficacy on comorbid TRD-PTSD remains insufficiently documented. In particular, flashbacks can occur during esketamine administration and their influence on clinical outcomes is unknown.

Objectives

Our main objective was to describe esketamine-induced traumatic flashbacks and their impact on clinical trajectories within a sample of patients with comorbid TRD-PTSD.

Methods

We retrospectively collected clinical data of patients receiving esketamine nasal spray for TRD with comorbid PTSD who experienced at least one flashback of their trauma during esketamine sessions across 11 psychiatric departments.

Results

Between February 2020 and March 2023, 22 adult patients with TRD met inclusion criteria. In sixteen patients (72.7%) flashbacks disappeared as the sessions progressed. In six patients (27.3%), esketamine treatment was stopped because of persistent flashbacks. When esketamine was continued, clinical response was observed both for depression and PTSD (depression response rate: 45.5% and remission rate: 22.7%; PTSD response rate: 45.5% and remission: 18.2%).

Limitations

The retrospective design of the study and the absence of a comparator group are the main limitations of our study.

Conclusions

Our results suggest that the occurrence of esketamine-induced traumatic flashbacks does not hinder clinical response. On the contrary, when managed appropriately and combined with targeted psychotherapy, it could even contribute to positive outcomes.

When Addressing Trauma Makes a Difference: A Case Report of Undiagnosed Complex Post-traumatic Stress Disorder

Complex post-traumatic stress disorder (C-PTSD) is an emergent diagnosis, which acknowledges the impact of prolonged interpersonal abuse on affect regulation, interpersonal functioning, and self-concept. We present the case of a 59-year-old woman who remained undiagnosed and untreated for this condition for three decades while under follow-up in mental health services for the diagnosis of personality disorder and bipolar disorder. The patient suffered repeated sexual abuse in her childhood, resulting in intrusive traumatic memories she emotionally and cognitively avoided, dissociative amnesia, a persistent inability to experience positive emotions, a persistent sense of guilt, re-experiencing phenomena, and hypervigilance toward others and their intentions to harm her. She persistently believed herself to be worthless, defective, inferior, and lacking value; had a history of affective dysregulation resulting in suspicion of bipolar disorder; and displayed a pattern of relationship avoidance. Addressing chronic trauma and assessing its impact offered deeper contextualization of the patient's symptoms and proved pivotal in redefining her diagnosis and providing access to trauma-focused psychotherapy, which is the mainstay of treatment for C-PTSD.

A Harm Reduction Framework for Integrated Treatment of Co-Occurring Opioid Use Disorder and Trauma-Related Disorders

The opioid epidemic has exposed a gulf in mental health research, treatment, and policy: Most patients with comorbid trauma-related disorder (TRD) and opioid use disorder (OUD) (TRD + OUD) remain undiagnosed or unsuccessfully treated for the combination of TRD symptoms and opioid use. TRD treatments tend to be psychotherapies that are not accessible or practical for many individuals with TRD + OUD, due to TRD treatment models not systematically incorporating principles of harm reduction (HR). HR practices prioritize flexibility and unequivocally improve outcomes and save lives in the treatment of OUD. Considering the urgent need to improve TRD + OUD treatment and outcomes, we propose that the OUD and TRD fields can be meaningfully reconciled by integrating HR principles with classic phasic treatment for TRD. Adding a "prestabilization" phase of treatment for TRD - largely analogous to the precontemplation Stage of Change - creates opportunities to advance research, clinical practice, and policies and potentially improve patient outcomes.

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.

Expert international trauma clinicians’ views on the definition, composition and delivery of reintegration interventions for complex PTSD

Background: Research has previously distinguished between complex post-traumatic stress disorder (CPTSD) and PTSD, with the former including a range of disturbances in self-regulatory capacities in addition to difficulties associated with PTSD. Clinical guidelines have previously recommended a phase-based approach for the treatment of CPTSD, yet the final 'reintegration' phase of treatment has been overlooked in research, with limited evidence into its value and effectiveness, and inconsistencies in its definitions and understanding.Objective: We set out to define and determine the key principles of 'reintegration' and to specify the components and method of delivery of treatment.Method: Leading national and international clinical and academic experts in CPTSD were interviewed and asked about their views of how 'reintegration' should be defined, its role in the treatment of CPTSD, what it should be composed of, the key principles of its delivery, and how it should be evaluated. We analysed transcripts of the interviews following the principles of Codebook Thematic Analysis.Results: We conducted 16 interviews with leading national and international experts with at least 10 years' experience of treating people with CPTSD. Themes derived from our analysis demonstrated that while the definition and composition of reintegration varied greatly between experts, the key principles in its delivery were consistent across all experts.Conclusions: The results of this study lay the foundation for a framework of what reintegration is and how it can be used in, but also highlight the need for more research to be conducted on the role of reintegration in the treatment of CPTSD. Consensus for the definition and composition of reintegration is still yet to be reached. Possible measures for evaluating reintegration should also be explored in the future.

Examination of ICD-11 PTSD and CPTSD using the International Trauma Questionnaire – Child and Adolescent version (ITQ-CA) in a sample of Danish children and adolescents exposed to abuse

Background: International research has established that children and adolescents are at risk for posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as defined by the WHO ICD-11. There is a need for a Danish language version of the International Trauma Questionnaire – Child and Adolescent (ITQ-CA) to assess symptoms of PTSD and CPTSD.

Objective: To test the ICD-11 formulations of PTSD and DSO (Disturbances of Self-Organization) using the ITQ-CA version in a sample of children exposed to abuse. Additionally, to study the distribution of symptoms and probable prevalence of ICD-11 PTSD and CPTSD among the population of children exposed to violence or sexual abuse.

Method: Confirmatory factor analysis of competing models of the dimensionality of the ITQ-CA was tested among a sample of 119 children and adolescents that were referred to the Danish Children Centres on suspicion of physical or sexual abuse or both. Latent class analysis (LCA) was used to study the distribution of symptoms and consequences of different operationalisations of functional impairment were explored.

Results: Findings supported a two-factor second-order model corresponding to the operationalisation of CPTSD in ICD-11 as the best representation of the data. Findings from the LCA suggested that symptoms were distributed in a pattern consistent with the ICD-11 proposal for CPTSD. CPTSD was more prevalent than PTSD regardless of the operationalisation of functional impairment.

Conclusion: ITQ-CA is a valid tool for identifying symptoms of ICD-11 PTSD and CPTSD among Danish children exposed to physical or sexual abuse. Further research is needed to study the relationship between ICD-11 C/PTSD symptomatology and anxiety and depression in this population.

The International Trauma Questionnaire – Child and Adolescent version (ITQ-CA) is a valid measure of symptoms of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD among Danish children exposed to physical or sexual violence.

The structure of the ITQ-CA in the Danish sample reflects the ICD-11 diagnostic algorithm.

CPTSD is a more prevalent disorder among children recently exposed to violence than PTSD.

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

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

Initial validation of the International Trauma Questionnaire (ITQ) in a sample of Chilean adults

BACKGROUND

ICD-11 Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) are stress-related disorders. The International Trauma Questionnaire (ITQ) is a widely used instrument to assess PTSD and CPTSD. To date, there is no evidence of the psychometric characteristics of the ITQ in Latin American countries.

OBJECTIVE

The aim of this study was to assess the construct and concurrent validity of the Latin American Spanish adaptation of the ITQ in a sample of Chilean adults.

METHODS

A sample of 275 Chilean young adults completed the ITQ, a traumatic life events checklist, the Adverse Childhood Experiences Questionnaire, the Depression Anxiety Stress Scales-21, and the Columbia-Suicide Severity Rating Scale short version. Four alternative confirmatory factor analysis models were tested. Correlation analyses were performed to determine concurrent validity with associated measures (number of reported traumatic events, number of adverse childhood experiences, anxiety, depression, and suicidal risk).

RESULTS

The second-order two-factor (PTSD and DSO) and the correlated first-order six-factor model provided acceptable fit; however, the first model showed a better fit based on the BIC difference. The PTSD and DSO dimensions, as well as the six ITQ clusters showed positive correlations with reported number of traumatic life-events, reported number of adverse childhood experiences, levels of anxiety, depression, and suicidal risk.

CONCLUSIONS

The ITQ Latin American Spanish adaptation provides acceptable psychometric evidence to assess PTSD and CPTSD in accordance with the ICD-11.

Body-and movement-oriented interventions for posttraumatic stress disorder: An updated systematic review and meta-analysis

This study is an update of the meta-analysis we published in 2019 on the effectiveness of body- and movement-oriented interventions (BMOIs) for adults with posttraumatic stress disorder (PTSD) in decreasing PTSD symptoms and secondary outcomes of depressive symptoms, sleep disturbance, and interoceptive awareness. Search terms for BMOIs and PTSD were combined to identify eligible studies in four bibliographical databases. Articles were selected if they included adult participants with a primary diagnosis of PTSD, included BMOI as one of the investigated therapies, were designed as a comparative outcome trial with any control condition, and involved a standardized outcome measure for PTSD symptom severity. This resulted in the addition of 14 new studies compared to the 2019 study. The meta-analysis, which included 29 studies in total, resulted in a mean Hedges' g effect size of 0.50, 95% CI [0.22, 0.79], in decreasing PTSD symptoms, with very high heterogeneity, I2 = 89%. Meta-analyses of secondary outcomes resulted in Hedges' g effect sizes of 0.37, 95% CI [0.08, 0.66] for depressive symptoms; 0.62, 95% CI [0.42, 0.81] for sleep quality; and -0.10, 95% CI [-0.23, 0.43] for interoceptive awareness. The risk of bias analysis resulted in some concerns or high risk of bias in almost all included studies; only one study had a low risk of bias. We conclude that BMOIs may be valuable for patients with PTSD. There is, however, still a lack of high-quality studies with proper control conditions and long-term follow-up periods from which to draw conclusions.

Post-traumatic stress symptoms and benefit finding: a longitudinal study among Italian health workers during the COVID-19 pandemic

PURPOSE

Research has highlighted that the exposure of healthcare professionals to the COVID-19 pandemic for over two years can lead to the development and persistence of symptoms characteristic of Post-Traumatic Stress Disorder (PTSD), with serious consequences on both the individual well-being and the quality of care provided. The present study was aimed at investigating the role of benefit finding in moderating post-traumatic stress symptoms (PTSS) over time.

METHODS

The longitudinal study, conducted between April and October 2020, involved 226 Italian health workers (44.7% nurses and midwives, 35% doctors, 20.3% technical and rehabilitation professionals), who filled out an online survey at the beginning of the study (T1), after three months (T2), and after six months (T3). Participants (77.4% women; mean age = 41.93, SD = 12.06) completed the PTSD Checklist for DSM-5 (PCL-5) and Benefit Finding, a 17-item questionnaire measuring the perceived level of positive consequences derived from stressful experiences. A hierarchical regression analysis highlighted the moderating effect of benefit finding (T2) on the association between PTSS values at T1 and T3.

RESULTS

A buffering effect was observed, with higher benefit finding levels reducing the magnitude of the bivariate association between PTSS assessed at the beginning and at the end of the study.

CONCLUSION

Findings suggest the potential mental health related benefits of interventions allowing health professionals to identify positive aspects in the experience of working under prolonged emergency circumstances, such as the pandemic ones.

Symptoms and levels of ICD-11 Prolonged Grief Disorder in a representative community sample of UK adults

BACKGROUND

Prolonged Grief Disorder (PGD) is a new disorder included in ICD-11 (WHO, 2018). There is a growing body of literature surrounding the prevalence and correlates of ICD-11 PGD symptoms as assessed using various measures. This study was the first to assess levels of ICD-11 PGD symptoms as measured by the International Prolonged Grief Disorder Scale (IPGDS), a self-report scale directly aligned with the ICD-11 definition of PGD, among the United Kingdom adult general population, and identify correlates.

METHOD

Participants included 2025 adults who participated in Wave 5 of the COVID-19 Psychological Research Consortium Study (C19PRC-UK). Prevalence rates of PGD were estimated based on two commonly used algorithms defined as 'strict' and 'moderate'. Sociodemographic, loss-related, and mental health correlates (i.e., anxiety, depression, mental health treatment seeking, loneliness) of strict and moderate PGD were then examined using multinomial logistic regressions.

RESULTS

It was found that 2.4% (n = 43) of participants met probable caseness for PGD using the strict criteria while 7.9% (n = 140) met probable caseness for PGD using the moderate criteria. Multinomial logistic regression analysis results showed, as predicted, that income, time since bereavement, death of a child, religiosity, and depression were associated with both moderate and strict PGD. Correlates of moderate PGD included country of residence, urbanicity, younger age of bereaved, and loneliness.

CONCLUSIONS

This study highlights that some symptoms of PGD are commonly reported in the general population, although relatively few meet the criteria for clinical significance. The routine assessment for PGD following a bereavement is discussed and the development of appropriate interventions are recommended.

Enhanced Skills Training in Affective and Interpersonal Regulation (ESTAIR): A New Modular Treatment for ICD-11 Complex Posttraumatic Stress Disorder (CPTSD)

ICD-11 Complex Posttraumatic Stress Disorder (CPTSD) is a relatively new condition; therefore, there is limited available evidence for its treatment. Prior to the recognition of CPTSD as a separate trauma condition, people who met criteria were often diagnosed with multiple co-morbid conditions such as PTSD, anxiety, depression, and emotional dysregulation difficulties. In the absence of a coherent evidence base, treatment tended to involve multiple treatments for these multiple conditions or lengthy phase-based interventions, often delivered in an integrative fashion, which was not standardized. In this paper, we present Enhanced Skills Training in Affective and Interpersonal Regulation (ESTAIR), a new flexible multi-modular approach for the treatment of CPTSD and its transdiagnostic symptoms. ESTAIR is consistent with trauma-informed and patient-centered care, which highlights the importance of patient choice in identification and sequencing in targeting CPTSD symptoms. Directions for future research are discussed.

Targeted Violence as a Risk Factor for Posttraumatic Stress Disorder Among Cisgender Gay, Bisexual, and Other Men Who have Sex with Men in the United States

Gay, bisexual, and other men who have sex with men (GBMSM) in the United States (US) are disproportionately exposed to interpersonal violence, which carries a high conditional risk for developing posttraumatic stress disorder (PTSD) and which is often motivated by sexual prejudice. We determined PTSD prevalence by violence attribution (motivated by sexual prejudice or not) and measured PTSD-attribution associations. Using a 2020 nationwide cross-sectional survey of 2,886 GBMSM who reported ever experiencing interpersonal violence, we performed multivariable modified Poisson regressions with robust variance estimators to examine differences in prevalence of current PTSD by how participants attributed the violence (occurring due to one's same-sex practices, not occurring due to one's same-sex practices, or being unsure if it occurred due to one's same-sex practices). Model results are reported as adjusted prevalence ratios (aPR) with 95% confidence intervals (CI). Median age was 27 years; 78.8% of participants identified as gay, and 62.2% were non-Hispanic White. Violence was attributed to same-sex practices by 45.8% of participants; 46.3% did not make this attribution, and 7.0% were unsure (0.9% preferred not to answer). Overall, 23.0% screened positive for PTSD, and PTSD prevalence was greater for those who attributed violence to same-sex practices (25.9% [342/1,321]; aPR = 1.55, 95% CI [1.34, 1.79]) and those who were unsure (33.5% [68/203]; aPR = 1.80, 95% CI [1.44, 2.25]) compared to those who did not make the attribution (18.1% [242/1,335]). Age modified this association, with participants 15 to 19 years old who made the attribution being significantly more likely to have PTSD relative to 20+ participants who also made the attribution. In addition to violence-prevention and stigma-mitigation efforts, interventions targeting attribution styles may be useful for violence-exposed GBMSM, especially teenagers.

Distinguishing between ICD-11 complex post-traumatic stress disorder and borderline personality disorder: clinical guide and recommendations for future research

Although complex post-traumatic stress disorder and borderline personality disorder are distinct disorders, there is confusion in clinical practice regarding the similarities between the diagnostic profiles of these conditions. We summarise the differences in the diagnostic criteria that are clinically informative and we illustrate these with case studies to enable diagnostic accuracy in clinical practice.

Complex post-traumatic stress disorder (cPTSD) and suicide risk: A multigroup mediation analysis exploring the role of post-traumatic symptomatology on hopelessness

Complex post-traumatic stress disorder (cPTSD) is a clinical condition that features not only PTSD symptoms, but also disturbances in self-organization. Patients with cPTSD have a higher incidence of psychiatric comorbidities, including suicidality. A key construct tightly related to suicidality is hopelessness, described as a feeling of despair, with a state of mind giving low or negative expectancies regarding one's future. Since there is a paucity of studies investigating the link between cPTSD and hopelessness as a risk factor for suicidality, the aim of this study was to examine the role of post-traumatic symptomatology as the primary driver of suicidality, as measured by hopelessness. 211 patients were enrolled and divided into two groups: PTSD (143 patients) and cPTSD (78 patients). A set of standardized measures was administered to study post-traumatic symptomatology, depression, and hopelessness. The results showed that compared to PTSD, cPTSD patients experienced more severe symptoms in all clinical outcomes (p < 0.001). The mediation analysis revealed a significant positive association between post-traumatic symptomatology and hopelessness in the cPTSD group, which was not significant in the PTSD group. Among PTSD patients, depression mediated 43.37% of the impact of post-traumatic symptomatology on suicidal ideation. Our results contribute to a better understanding of complex post-traumatic symptomatology, further highlighting its role in the pathogenesis of suicidality. Hence, these findings have important clinical implications, suggesting that targeted, trauma-focused interventions might effectively prevent hopelessness and therefore suicide risk in patients with cPTSD.

Sleep Disturbances in Panic Disorder with Comorbid Complex PTSD: A Possible Relationship and Different Psychopathology?

BACKGROUND

Several studies have shown the possible link between trauma and sleep disturbances, particularly in anxiety disorders. This issue could be because sympathetic hyperarousal is central to both disorders, probably caused by a dysregulation of the noradrenergic system. This study aimed to establish if the comorbidity with complex post-traumatic stress disorder (cPTSD) is associated with sleep disturbances in panic disorder (PD) and if the presence of poor sleep quality is associated with a higher psychopathological burden.

METHODS

Participants (N = 211) with PD completed the International Trauma Questionnaire concerning their most troubling experience, the Hamilton Anxiety Rating Scale (HAM-A), and the Pittsburgh Sleep Quality Index (PSQI) to assess anxiety symptoms and sleep disturbances, respectively.

RESULTS

The sample was divided into two subgroups based on the presence of cPTSD. No significant differences emerged in the bivariate analyses for what concerns sociodemographic features. As for the scores of the psychopathological scales, the analysis highlighted statistically significant differences between the subgroups. Subjects with cPTSD reported significantly higher HAM-A total scores. As for the disturbances in self-organization (DSO) and PSQI scores, these were all significantly higher in the cPTSD subsample. At the logistic regression, the presence of cPTSD was inserted as the dependent variable, while the PSQI scores of the subscales evaluating subjective sleep quality, sleep duration, sleep efficacy, and the use of hypnotics were used as independent variables. The presence of cPTSD was significantly associated with the PSQI subscores for subjective sleep quality and use of hypnotics.

CONCLUSIONS

Patients with PD exhibit more severe sleep disturbances and a higher anxiety burden when experiencing prolonged trauma. Therapeutic advances are needed in this field to target these symptomatologic domains.

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.

Factors associated with the outcomes of a novel virtual reality therapy for military veterans with PTSD: Theory development using a mixed methods analysis

BACKGROUND

Multi-modular motion-assisted memory desensitization and reconsolidation therapy (3MDR) is a new psychological intervention for people with post-traumatic stress disorder (PTSD). 3MDR is immersive, delivered in a virtual reality environment, and emphasises engagement, recollection and reprocessing.

OBJECTIVE

Through a theory-driven examination of data relating to 10 out of 42 UK military veterans taking part in a trial of 3MDR, the principal objective was to explore the complex interrelationships between people, interventions and context and to investigate how factors within these domains interacted in specific outcome typologies.

METHOD

Quantitative and qualitative data relating to 10 trial participants were derived from: researcher-assessed and self-report clinical measures; interviews; physiological recordings; words describing thoughts and feelings during therapy; and subjective unit of distress scores. Using a convergent mixed methods approach, data were tabulated using a person, intervention and context model. Participant summaries were grouped into outcome typologies, followed by an analysis of data convergence and divergence within each and an interpretation of identified patterns.

RESULTS

Three outcome response typologies were identified: dramatic improvement, moderate improvement and minimal improvement. Within the person domain, factors associated with outcomes included walking capacity, commitment and ability to complete therapy, and levels of subjective distress. Within the intervention domain, factors associated with outcomes related to image selection and use, therapeutic alliance and orientations towards the tailoring of sessions. Within the context domain, factors associated with outcomes included reactions to the therapy environment. The patterning of secondary outcomes broadly corresponded with primary outcomes within each typology. Alongside patterned data differentiating aspects of the person, intervention and context domains, within the three response typologies data also existed where no obvious patterning was detected.

CONCLUSIONS

The model developed here may have novel value in evaluating a range of personalised interventions, but further work is needed before confident assertions can be made of who is likely to benefit from 3MDR specifically.

Evaluation of an adapted version of the International Trauma Questionnaire for use by people with intellectual disabilities

AIMS

The International Trauma Questionnaire (ITQ) is a novel assessment instrument that is aligned to the ICD-11 diagnoses of post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD). The purpose of this study was to develop and evaluate an adapted version of the ITQ suitable for use by people with intellectual disabilities.

METHODS

The ITQ-ID follows the original ITQ, using wording developed in collaboration with a focus group of people with intellectual disabilities The ITQ-ID was administered to 40 people with intellectual disabilities recruited from learning disability forensic and community settings, alongside a Trauma Information Form and the Impact of Event Scale-Intellectual Disabilities (IES-IDs).

RESULTS

Most participants reported multiple traumatizing events. Around half of the participants met strict criteria for a diagnosis of PTSD, and around three quarters met looser criteria. Depending on definitions, between 66% and 93% of those who met criteria for PTSD also met criteria for a diagnosis of CPTSD. The ITQ-ID showed a single-component structure, with very good-to-excellent internal consistency, excellent test-retest reliability, and evidence of concurrent, discriminant, and content validity.

SIGNIFICANCE

The results support the potential of the ITQ-ID for assessment of PTSD and CPTSD in people with intellectual disabilities in both clinical and research contexts and highlight the need for further validation work.

Investigation of self-treatment with lysergic acid diethylamide and psilocybin mushrooms: Findings from the Global Drug Survey 2020

BACKGROUND

Growing numbers of people are using psychedelics for personal psychotherapy outside clinical settings, but research on such use is scarce.

AIMS

This study investigated the patterns of use, self-reported outcomes and outcome predictors of psychedelic 'self-treatment' of mental health conditions or specific worries/concerns in life.

METHODS

We use data from the Global Drug Survey 2020, a large online survey on drug use collected between November 2019 and February 2020. In all, 3364 respondents reported their self-treatment experiences with lysergic acid diethylamide (N = 1996) or psilocybin mushrooms (N = 1368). The primary outcome of interest was the 17-item self-treatment outcome scale, items reflecting aspects of well-being, psychiatric symptoms, social-emotional skills, and health behaviours.

RESULTS

Positive changes were observed across all 17 outcome items, with the strongest benefits on items related to insight and mood. Negative effects were reported by 22.5% of respondents. High intensity of psychedelic experience, seeking advice before treatment, treating with psilocybin mushrooms and treating post-traumatic stress disorder were associated with higher scores on the self-treatment outcome scale after averaging values across all 17 items. Younger age, high intensity of experience and treating with LSD were associated with increased number of negative outcomes.

CONCLUSIONS

This study brings important insights into self-treatment practices with psychedelics in a large international sample. Outcomes were generally favourable, but negative effects appeared more frequent than in clinical settings. Our findings can help inform safe practices of psychedelic use in the community, and inspire clinical research. Future research can be improved with utilisation of prospective designs and additional predictive variables.

Associations among psychosis, mood, anxiety, and posttraumatic stress symptoms: A network analysis

The associations among psychotic experiences (i.e., hallucinations and delusions), trauma exposure, and posttraumatic stress symptoms are complex and multidirectional. Using network analysis to understand how psychotic experiences and symptoms of posttraumatic stress disorder (PTSD) relate to one another may identify new interventional targets to treat comorbidity and its underlying pathological processes. This study aimed to use network analysis to examine the associations among psychotic experiences; negative symptoms of psychosis; and symptoms of PTSD, anxiety, and depression. In this population-based cohort study, 4,472 participants (36.7% male) were assessed for psychotic experiences, negative symptoms of psychosis, PTSD, anxiety, and depression at age 23 (M = 23.86 years, SD = 0.520) or 24 years (M = 24.03, SD = 0.848). Associations among symptoms were assessed via network analysis. Exploratory graph analysis identified three clusters of densely connected symptoms within the overall network: psychotic experiences; PTSD symptoms; and depressive and anxiety symptoms and negative symptoms of psychosis. Psychotic experiences had the strongest associations with other symptoms in the network, and symptoms of anxiety played a key role in bridging psychotic experiences, symptoms of PTSD, and depressive symptoms. Consistent with the stress reactivity and affective models for psychotic experiences, the results suggest that symptoms of anxiety and emotional distress (e.g., hyperarousal, panic) may have a key role in the development and maintenance of psychotic experiences and symptoms of PTSD. Targeting these symptoms may ameliorate symptom burden transdiagnostically.

Treatment of Comorbid Disorders, Syndromes, and Symptoms of Posttraumatic Stress Disorder Related to Childhood Maltreatment with STAIR-NT

Abstract. Background: Early interpersonal traumatic events, such as childhood maltreatment, increase the risk of developing complex posttraumatic stress symptoms. The biphasic treatment program STAIR-NT (Skills Training for Affective and Interpersonal Regulation with Narrative Therapy), developed specifically for this patient group, combines interventions to improve emotion regulation and interpersonal skills with narrative therapy. Objective: Many affected patients with PTSD after childhood maltreatment also suffer from various comorbid mental disorders and symptoms that can affect and impede the course and outcome of treatment with STAIR-NT. Method: Based on experience from a current treatment study, we provide recommendations for integrating treatment of comorbid mental symptoms into STAIR-NT. Results / Conclusion: Training affective and interpersonal regulation skills in the first treatment phase offers various interventions to efficiently adapt transdiagnostic mechanisms such as emotion dysregulation. In cases of severe comorbid mental disorders or symptoms, adding disorder-specific interventions to STAIR-NT may be indicated.

PTSD (Posttraumatic Stress Disorder) in Teachers: A Mini Meta-Analysis during COVID-19

BACKGROUND

Since March 2020, when the World Health Organization (WHO) declared the COVID-19 pandemic, in order to stop the spread of the virus, unprecedented measures were taken worldwide. One of the most important measures was the closure of schools and educational centers around the world in 2020, and very extreme health protocols have been in place in educational centers since they were reopened. From early childhood education to universities, teachers first had to adapt in a short period time to online classes and then continuously readapt to new protocols according to the pandemic situation. This academic environment, in addition to the pandemic situation itself, has favored the emergence of mental disorders such as Post-Traumatic Stress Disorder (PTSD).

MATERIALS AND METHODS

Medline via PubMed and other databases were searched for studies on the prevalence of PTSD in teachers from 1 December 2019 to 1 October 2022. A total of five studies were included in this review. Our results show a prevalence of PTSD of 11% reported by teachers. No subgroups nor meta-regression analyses were performed due to the insufficient number of studies available.

CONCLUSIONS

The results suggest that teachers are suffering from PTSD, so it is important to carry out more studies worldwide. Similarly, measures to improve the mental health and well-being of teachers during the pandemic and post-pandemic periods are needed.

Predictors of complex PTSD: the role of trauma characteristics, dissociation, and comorbid psychopathology

BACKGROUND

Complex Posttraumatic Stress Disorder (CPTSD) has previously been associated with earlier trauma onset, repeated interpersonal traumatization, more dissociation, and more comorbid psychopathology. However, it is still debated if the afore-mentioned risk factors are related to CPTSD diagnosis or rather indicative of a more severe form of post-traumatic distress. The aim of this study was to compare patients with a CPTSD diagnosis to those with PTSD in trauma characteristics (onset, chronicity, interpersonal nature, familiarity with perpetrator), dissociation, and psychiatric comorbidities, while accounting for symptom severity.

METHODS

In total, N = 81 patients with a trauma history (n = 43 with CPTSD; n = 37 with PTSD) underwent diagnostic interviews by trained clinicians and completed measures on CPTSD symptom severity, trauma characteristics, and dissociation (Screening for Complex PTSD; Dissociative Experience Scale Taxon).

RESULTS

Patients with CPTSD reported earlier onset of trauma, more trauma perpetrated by acquaintances or family members, and more comorbidities than those with PTSD, also when accounting for symptom severity. No group differences in chronicity and dissociation were found. Severity of CPTSD was associated with earlier onset, familiarity with perpetrator, more comorbid (affective) disorders, and dissociation in both diagnostic groups.

CONCLUSION

Findings largely confirm earlier research, suggesting that CPTSD is associated with traumatic events that start earlier in life and are perpetrated by acquaintances. Focusing on transdiagnostic symptoms, such as dissociation, may help to detain symptom deterioration. Due to the small sample size, findings need to be interpreted with caution and further research is needed to replicate findings in larger samples. Future research should also elucidate possible working mechanisms besides dissociation, such as emotion dysregulation or negative self-image.

Urbanicity, posttraumatic stress disorder, and effect modification by socioeconomic position: A nested case-control study of the Korean National Health Insurance Database

BACKGROUND

We aimed to estimate the association between urbanicity and the onset of posttraumatic stress disorder (PTSD) and to investigate heterogeneity therein according to age and socioeconomic position (SEP).

METHODS

We analyzed administrative data from the Korean National Health Insurance Database for patients with PTSD from 2004 to 2018 (N = 109,230) and for a 1:4 sample of age-, sex-, and enrollment year-matched controls. Information on eligibility, SEP (proxied by insurance premium), place of residence, diagnosis, and medical claims was obtained. Urbanicity of administrative districts was assessed using data from the Korean Statistical Information Service, 2005-2018. We estimated hazard ratios (HRs) from baseline and time-dependent models. Subgroup analyses and polynomial splines were used to investigate heterogeneity by age and SEP.

RESULTS

Urbanicity was associated with an increased risk of PTSD (per 10%p increase, HR = 1.056, 95% CI 1.050-1.061). A positive association was estimated among patients aged 0-29 years (HR = 1.115, CI 1.106-1.124), while negative associations were estimated among patients aged 30-64 years (HR = 0.990, CI 0.987-0.994) and 65 years or older (HR = 0.992, CI 0.979-1.014). The estimated associations with urbanicity were more prominent at the extremes of SEP, but only among younger participants.

CONCLUSION

Urban residence was associated with an increased risk of PTSD diagnosis. The estimated association was larger among younger individuals (but not among middle-aged and older individuals). Among younger individuals, the estimated association was larger at both extremes of SEP.

The Rising of the Shield hero. Development of the Post-Traumatic Symptom Questionnaire (PTSQ) and Assessment of the Protective Effect of self-esteem from trauma-related Anxiety and Depression

Background

Adverse life events such as life-threatening accidents, domestic and/or sexual violence, organic diseases (i.e., cancer), or COVID-19 can have a strong traumatic impact - generating reactions as intrusive thoughts, hyperarousal, and avoidance. Indeed, the traumatic impact of COVID-19 seems to lead individuals to experience anxiety and depression. However, the Anxiety-Buffer Hypothesis suggests that self-esteem could be considered a shield (buffer) against traumatic experiences and their outcomes (i.e., anxiety and depression). The present study has two objectives. First, to develop a measure of the impact of the traumatic event considering the aforementioned reactions. Second, to test the process - triggered by COVID19-related traumatic experience - in which self-esteem buffers the path that leads to anxiety and depression.

Method

In Study 1 (N = 353), the Post-Traumatic Symptom Questionnaire (PTSQ) was developed and a deep investigation of its psychometric properties was conducted. In Study 2 (N = 445), a structural equation model with latent variables was performed to assess the buffering effect of self-esteem.

Results

The PTSQ has excellent fit indices and psychometric properties. According to the ABH, results confirm the buffering effect of self-esteem in the relationships between traumatic symptoms and both anxiety and depression.

Conclusion

On the one hand, the PTSQ is a solid and reliable instrument. On the other hand, that self-esteem is a protective factor against anxiety and depression related to a traumatic experience - such as COVID-19. Targeted psychological interventions should be implemented to minimize the psychological burden of the illness while promoting adaptation and positive aspects of oneself.

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.

Prevalence and sociocultural correlates of post-traumatic stress disorder and complex PTSD among Chinese community health service users in Hong Kong

OBJECTIVES

Complex post-traumatic stress disorder (CPTSD) is a newly recognized trauma disorder in ICD-11. Little is known about the prevalence and correlates of CPTSD in primary care settings. Its cultural aspects also remained minimally explored. This study investigated the prevalence and sociocultural correlates of PTSD and complex PTSD among Chinese community health service users in Hong Kong.

METHODS

This study investigated ICD-11 PTSD and CPTSD in a sample of adults (N = 376) who had recently received services from Registered Chinese Medicine Practitioners in Hong Kong. Traditional Chinese medicine service is part of primary care services in Chinese societies. Participants completed self-report measures of CPTSD, trauma exposure, perceived family support, perceived caregiver's Chinese traditionality/modernity, participation (social activities and occupational productivity), depression and pain.

RESULTS

The past-month prevalence of ICD-11 PTSD and CPTSD was 5.6% and 18.4%, respectively, in our sample. Chi-square tests and one-way ANOVAs revealed that participants with CPTSD were younger and reported more trauma, lower family support, lower levels of social participation and productivity, more depressive symptoms and pain, and more social welfare and mental health service usages than those without PTSD. We found that perceived caregiver's Chinese modernity (e.g. egalitarianism) was negatively correlated with CPTSD symptoms. Apart from age, non-betrayal trauma had the strongest association with classical PTSD symptoms, while betrayal trauma and perceived family support had the strongest association with disturbances in self-organization symptoms.

CONCLUSION

This study provides the first data regarding the prevalence and correlates of ICD-11 PTSD and CPTSD among community health service users in Hong Kong. PTSD and CPTSD are common but often unrecognized mental health problems which are associated with more impairments and more service needs.

The effectiveness of trauma-focused psychotherapy for complex post-traumatic stress disorder: A retrospective study

OBJECTIVE

We retrospectively evaluated the effectiveness of trauma-focused psychotherapy (TF-P) versus stabilization and waiting in a civilian cohort of patients with an 11th version of the international classification of disease (ICD-11) diagnosis of complex post-traumatic stress disorder (CPTSD).

METHODS

We identified patients with CPTSD treated at a specialist trauma service over a 3-year period by triangulating evidence from self-report questionnaires, file review, and expert-clinician opinion. Patients completed a phase-based treatment: stabilization consisting of symptom management and establishing safety, followed by waiting for treatment (phase 1); individual TF-P in the form of trauma-focused cognitive behavioral therapy (TF-CBT), or eye movement desensitization and reprocessing (EMDR) or TF-CBT plus EMDR (phase 2). Our primary outcome was PTSD symptoms during phase 2 versus phase 1. Secondary outcomes included depressive symptoms, functional impairment, and a proxy CPTSD measure. Exploratory analysis compared outcomes between treatments. Adverse outcomes were recorded.

RESULTS

Fifty-nine patients were included. Compared to receiving only phase 1, patients completing TF-P showed statistically significant reductions in PTSD [t(58) = -3.99, p < 0.001], depressive symptoms [t(58) = -4.41, p < 0.001], functional impairment [t(58) = -2.26, p = 0.028], and proxy scores for CPTSD [t(58) = 4.69, p < 0.001]. There were no significant differences in outcomes between different treatments offered during phase 2. Baseline depressive symptoms were associated with higher PTSD symptoms and functional impairment.

CONCLUSIONS

This study suggests that TF-P effectively improves symptoms of CPTSD. However, prospective research with validated measurements is necessary to evaluate current and new treatments and identify personal markers of treatment effectiveness for CPTSD.
