Posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as per ICD-11 proposals: A population study in Israel

Digital-Based Interventions for Complex Post-Traumatic Stress Disorder: A Systematic Literature Review

Research has shown that complex post-traumatic stress disorder (cPTSD) differs from post-traumatic stress disorder (PTSD) on core symptoms relating to the individual's sense of self, and this has driven the need for treatment approaches to address these specific features of cPTSD. The COVID-19 pandemic has led to the increased use of digital-based interventions (DBIs) to treat mental illnesses, including trauma-related disorders. However, while evidence for the use of DBIs for PTSD has previously been synthesized, the current review is the first synthesis of research on the use of DBIs for cPTSD. A systematic search of Scopus, PsychINFO, and EBSCOhost was conducted, using search terms targeting "cPTSD" and "DBIs," to identify research on the use of DBIs to treat cPTSD symptoms. Ten papers were identified, which provided preliminary evidence for the efficacy of DBIs to reduce cPTSD symptoms. Further, DBIs were reported as acceptable by individuals with a history of complex trauma. The paper also provides insight into the therapeutic approaches adopted, digital modalities utilized, safety measures included, and whether/to what degree support was provided. While DBIs show promise for treating cPTSD, there is substantial room for advancement of the empirical evidence base for these approaches. Both clinical and research-based recommendations are provided separately.

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.

Holocaust centrality, anxiety, and other risk factors associated with terror threat salience among descendants of Holocaust survivors

The study examined risk factors for sensitivity to terror threats among descendants of Holocaust survivors (Holocaust G1) during a significant rise in terrorist attacks in Israel. We examined the association of the number of familial Holocaust G1, trauma exposure, probable posttraumatic stress disorder (PTSD), anxiety symptoms, and Holocaust centrality with terror threat salience (TTS) in children and grandchildren of Holocaust G1 (Holocaust G2; G3). A web-based national sample included 297 Holocaust G2 (Mage=62.95, SD=10.25), 224 comparison G2 (Mage=61.79, SD=10.13), 379 Holocaust G3 (Mage=34.02, SD=8.65) and 171 comparison G3 (Mage=33.55, SD=8.26). Participants completed questionnaires on background characteristics, Holocaust background, trauma exposure, probable PTSD, anxiety symptoms, Holocaust centrality, and TTS. Findings showed that Holocaust G2 and G3 reported higher Holocaust centrality and TTS relative to comparisons, and Holocaust G3 reported higher levels of anxiety than comparison G3. The number of Holocaust G1, background characteristics, Holocaust centrality, and anxiety symptoms were associated with TTS in G2 and G3. Probable PTSD and trauma exposure were also associated with TTS in G2 and G3, respectively. Results highlight Holocaust centrality and anxiety among the factors associated with an increased preoccupation with terror threats in Holocaust descendants. Practitioners should implement interventions focusing on these factors, particularly at times of increased terrorism.

PTSD, distress and substance use in the aftermath of October 7th, 2023, terror attacks in Southern Israel

The October 7th, 2023, terror attacks in Israel were characterized by a scope and magnitude not previously known to Israeli citizens. The aim of this study was to examine the prevalence and correlates of posttraumatic stress disorder (PTSD), emotional distress and use of addictive substances among Israeli adults, approximately one month following the attacks. PTSD was assessed with the Posttraumatic Stress Disorder Checklist (PCL-5) and emotional distress was assessed with a brief version of the Hopkins Symptom Checklist (HSCL-25). Participants also ranked the degree of change in their frequency of use of six addictive substances. The final sample consisted of 415 Jewish and Arab Israeli adults. Results indicate that one month following the attacks, 31.4% of the total sample qualified for positive screening of PTSD. An increase in the use of tobacco, alcohol, tranquilizers and sleep medications was reported by 16.5%, 10.1%, 11.1% and 10.6% of the sample, respectively. Being at a younger age, of female sex and with increased exposure to the attacks was associated with increased levels of PTSD (β = -0.24, p < 0.001; β = 0.19, p < 0.001 and β = 0.29, p < 0.001, respectively) and increased distress (β = -0.22, p < 0.001, β = 0.26, p < 0.001 and β = 0.19, p < 0.001, respectively). Being male was significantly associated with increased use of cannabis (Adjusted Odds Ratio (AOR) = 4.73, 95% Confidence Interval (CI) = 1.70-13.13, p = 0.003), and level of exposure to traumatic events was significantly associated with increased use of tranquilizers (AOR = 1.58, 95% CI = 1.17-2.13, p = 0.003). The high magnitude of symptomatic response should alert other countries as they prepare for national disasters.

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.

Tracing the paths: a systematic review of mediators of complex trauma and complex post-traumatic stress disorder

Complex trauma is associated with complex-posttraumatic stress disorder (CPTSD). While dissociative processes, developmental factors and systemic factors are implicated in the development of CPTSD, there are no existing systematic reviews examining the underlying pathways linking complex trauma and CPTSD. This study aims to systematically review evidence of mediating factors linking complex trauma exposure in childhood (birth to eighteen years of age) and subsequent development of CPTSD (via self-reports and diagnostic assessments). All clinical, at-risk and community-sampled articles on three online databases (PsycINFO, MedLine and Embase) were systematically searched, along with grey literature from ProQuest. Fifteen articles were eligible for inclusion according to pre-determined eligibility criteria and a search strategy. Five categories of mediating processes were identified: 1) dissociative processes; 2) relationship with self; 3) emotional developmental processes; 4) social developmental processes; and 5) systemic and contextual factors. Further research is required to examine the extent to which targeting these mediators may act as mechanisms for change in supporting individuals to heal from 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.

The German PCL-5: evaluating structural validity in a large-scale sample of the general German population

Background: In attempts to elucidate PTSD, recent factor analytic studies resulted in complex models with a proliferating number of factors that lack psychometrical and clinical utility. Recently, suggestions have been made to optimize factor analytic practices to meet a refined set of statistical and psychometric criteria.Objective: This study aims to assess the factorial structure of the German version of the PCL-5, implementing recent methodological advancements to address the risk of overfitting models. In doing so we diverge from traditional factor analytical research on PTSD.Method: On a large-scale sample of the German general population (n = 1625), exploratory factor analyses were run to investigate the dimensionality found within the data. Subsequently, we validated and compared all model suggestions from our preliminary analyses plus all standard and common alternative PTSD factor models (including the ICD-11 model) from previous literature with confirmatory factor analyses. We not only consider model fit indices based on WLSMV estimation but also deploy criteria such as favouring less complex models with a parsimonious number of factors, sufficient items per factor, low inter-factor correlations and number of model misspecifications.Results: All tested models showed adequate to excellent fit in respect to traditional model fit indices; however, models with two or more factors increasingly failed to meet other statistical and psychometric criteria.Conclusion: Based on the results we favour a two-factor bifactor model with a strong general PTSD factor and two less dominant specific factors - one factor with trauma-related symptoms (re-experiencing and avoidance) and one factor with global psychological symptoms (describing the trauma's higher-order impact on mood, cognition, behaviour and arousal).From the perspective of clinical utility, we recommend the cut-off scoring method for the German version of the PCL-5. Basic psychometric properties and scale characteristics are provided.

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.

Amygdala-related electroencephalogram neurofeedback as add-on therapy for treatment-resistant childhood sexual abuse posttraumatic stress disorder: feasibility study

AIM

Childhood sexual abuse (CSA) among women is an alarmingly prevalent traumatic experience that often leads to debilitating and treatment-refractory posttraumatic stress disorder (PTSD), raising the need for novel adjunctive therapies. Neuroimaging investigations systematically report that amygdala hyperactivity is the most consistent and reliable neural abnormality in PTSD and following childhood abuse, raising the potential of implementing volitional neural modulation using neurofeedback (NF) aimed at down-regulating amygdala activity. This study aimed to reliably probe limbic activity but overcome the limited applicability of functional magnetic resonance imaging (fMRI) NF by using a scalable electroencephalogram NF probe of amygdala-related activity, termed amygdala electrical-finger-print (amyg-EFP) in a randomized controlled trial.

METHOD

Fifty-five women with CSA-PTSD who were in ongoing intensive trauma-focused psychotherapy for a minimum of 1 year but still met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) PTSD criteria were randomized to either 10 add-on sessions of amyg-EFP-NF training (test group) or continuing psychotherapy (control group). Participants were blindly assessed for PTSD symptoms before and after the NF training period, followed by self-reported clinical follow-up at 1, 3, and 6 months, as well as one session of amygdala real-time fMRI-NF before and after NF training period.

RESULTS

Participants in the test group compared with the control group demonstrated a marginally significant immediate reduction in PTSD symptoms, which progressively improved during the follow-up period. In addition, successful neuromodulation during NF training was demonstrated.

CONCLUSION

This feasibility study for patients with treatment-resistant CSA-PTSD indicates that amyg-EFP-NF is a viable and efficient intervention.

Posttraumatic stress disorder in Belgian police officers: prevalence and the effects of exposure to traumatic events

Background: Police officers are at considerable risk of developing posttraumatic symptoms because they frequently encounter violent or emotionally disturbing incidents. We investigate experiences with potentially traumatic events (PTE), traumatic exposure, and the prevalence of probable posttraumatic stress disorder (PTSD), complex PTSD and subclinical PTSD in a sample of Belgian police officers.Methods: In total, 1,465 police officers from 15 Belgian Local Police zones participated in a web-based survey, consisting of three segments: evaluating experiences with a list of 29 PTE, assessing if any of these PTE accounted for traumatic exposure, and evaluating 1-month probable PTSD, complex PTSD and subclinical PTSD prevalence using the International Trauma Questionnaire (ITQ).Results: Police officers frequently experience a wide range of PTE. A large majority of 93.0% reports traumatic exposure. Assessment with ITQ shows a 1-month prevalence of 5.87% for probable PTSD and 1.50% for probable complex PTSD, while an additional 7.58% report subclinical PTSD. No demographic variables influenced PTSD prevalence. Cumulative PTE experiences in itself did not predict PTSD, while the characteristics of certain PTE did entail a higher prevalence of probable PTSD and subclinical PTSD.Discussion: This study is the first to evaluate experiences with PTE, traumatic exposure and 1-month prevalence of probable PTSD, complex PTSD, and subclinical PTSD in Belgian police officers. Police officers are frequently confronted with a broad variety of PTE, and a large majority reports traumatic exposure. The 1-month prevalence of probable PTSD is significantly higher compared to previous international research in the general population, but lower than in similar international research involving police officers. In this study, cumulative PTE experiences in itself did not reliably predict PTSD, while the characteristics of certain PTE did. Posttraumatic symptoms are an important mental health challenge in Belgian police.

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.

Translation and validation of the Dari International Trauma Questionnaire (ITQ) in Afghan asylum seekers and refugees

Background: The International Trauma Questionnaire (ITQ) is a standardized and validated measure aligned with the 11th version of the International Classification of Diseases (ICD-11) diagnostic criteria to assess post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (CPTSD). It has been translated into 25 different languages, but is yet to be translated into Dari and validated for use in the Afghan population.Objective: This study aimed (1) to translate and culturally adapt the ITQ for use in Dari; (2) to assess the construct validity and composite reliability of ICD-11 PTSD and CPTSD using the Dari ITQ; and (3) to examine the concurrent, convergent, and discriminant validity of the Dari ITQ.Method: The Dari ITQ was validated through the completion of a set of standardized measures by 305 Afghan asylum seekers and refugees in Austria. Factorial analyses and psychometric properties of the Dari ITQ were assessed using confirmatory factor analysis (CFA), bivariate correlations, and multivariate regression.Results: Asylum seekers showed significantly higher levels of ICD-11 CPTSD symptomatology and probable diagnoses of ICD-11 PTSD, Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) PTSD, anxiety, depression, and psychological distress in comparison to refugees. CFA results supported the two-factor second-order model comprised of the PTSD and disturbances in self-organization (DSO) as the best fit to the data. The psychometric adequacy of this model in the Dari ITQ was evidenced by high factor loadings and excellent internal reliability. The Dari ITQ showed satisfactory concurrent, convergent, and discriminant validity.Conclusion: The current study supports the statistical validity and cultural sensitivity of the Dari ITQ in identifying symptoms of ICD-11 PTSD and CPTSD among Afghan asylum seekers and refugees.

The relationship between multiple traumatic events and the severity of posttraumatic stress disorder symptoms – evidence for a cognitive link

Background: Previous research has shown that multiple traumatic experiences cumulatively increase the risk for the development of severe symptoms of posttraumatic stress disorder (PTSD). Yet, little is known about the specific psychological mechanism through which this increased risk comes about.Objective: In the present study, we examined a possible cognitive link between multiple traumatic events and PTSD symptom severity through dysfunctional cognitions and expectations.Methods: A sample of patients with a diagnosed PTSD (N = 70; M_Age= 42.06; 82% female) and high symptom burden (IES-R M = 79.24) was examined. On average, patients had experienced 5.31 different traumatic events. In a structural equation model, we tested the hypothesis that the relationship between multiple traumatic experiences and PTSD symptom severity is mediated through dysfunctional general cognitions and dysfunctional situation-specific expectations. General trauma-related cognitions were assessed with the Posttraumatic Cognition Inventory (PTCI) and trauma-related situational expectations were assessed with the Posttraumatic Expectations Scale (PTES).Results: The direct effect of the number of traumatic events on PTSD symptom severity was non-significant. Instead, as hypothesised, there was evidence for a significant indirect effect via dysfunctional general cognitions and situation-specific expectations.Conclusions: The current results further specify the cognitive model of PTSD by indicating that the relationship between the number of traumatic events and PTSD symptom severity is mediated through dysfunctional cognitions and expectations. These findings emphasise the importance of focused cognitive treatment approaches that seek to modify dysfunctional cognitions and expectations in people with multiple traumatic experiences.

Depression, PTSD, and suicidal ideation among ex-ultra-Orthodox individuals in Israel

Introduction: Disaffiliating from an ultra-Orthodox society is complex and challenging. The process includes dealing with culture shock, traumatic experiences, education gaps, and disconnection from familiar surroundings. Thus, ex-ultra-Orthodox individuals (ex-ULTOIs) may face loneliness, lack of belongingness, and loss of meaning, which may relate to high psychological distress such as depression and suicide ideation. In the present study, we sought to shed light on the distress of ex-ULTOIs in Israel and to understand the disaffiliation-related characteristics that may relate to their distress levels.Method: The sample comprised 755 participants, aged 19-54, who left their ultra-Orthodox Jewish lifestyle and communities. Participants completed self-report questionnaires tapping depression, anxiety, posttraumatic stress disorder (PTSD) symptoms, suicide ideation and behaviour, as well as demographics and disaffiliation-related characteristics.Results: Nearly half of the sample (N = 332, 45.9%) reported symptom intensity meeting the current criteria for major depressive disorder. Moreover, 46.7% reported symptoms meeting PTSD criteria, and 34.5% reported having suicidal ideations in the past year. Hierarchical regression analyses revealed that the intensity of past negative life events, the nature of motives for disaffiliation, and the longer duration of the disaffiliation process contributed to the severity of distress.Conclusions: The study's findings reveal that ex-ULTOIs suffer from high mental pain levels, particularly depression, PTSD, and suicidal risk. Importantly, experiencing disaffiliation as traumatic and longer durations of the process may facilitate greater mental pain and distress symptoms. These findings emphasize that ex-ULTOIs must be continually assessed, especially when their disaffiliation processes are experienced as traumatic.

What are the predictive variables that increase the risk of developing a complex trauma? A meta-analysis

In 2018, Complex Post Traumatic Stress Disorder (CPTSD) was officially recognized as a distinct syndrome in the International Classification of Diseases, 11th Revision (ICD-11). This recognition aimed to differentiate between neurotic disorders secondary to stressful situations and somatoform disorders, and disorders specifically associated with stress. The inclusion of CPTSD in the ICD-11 marked the culmination of two decades of research focused on understanding its symptoms, treatments, and risk factors. However, despite the progress made, a comprehensive meta-analysis to elucidate the specific risk factors and impact on the development of CPTSD is still lacking. The objective of this article is to conduct such a meta-analysis. A total of 24 studies were selected for analysis, and the findings revealed several key risk factors associated with the development of CPTSD. The main risk factor identified is having experienced sexual abuse in childhood (k = 12; OR = 2.880). In addition, childhood physical abuse (k = 11; OR = 2.841), experiencing emotional neglect during childhood (k = 5; OR = 2.510), physical abuse throughout life (k = 8; OR = 2.149) and being a woman (k = 13; OR = 1.726) were also significant risk factors.

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.

Trauma-related and risk factors associated with perceived exacerbation in psychological distress due to the Russo-Ukrainian war

This study examined trauma-related and other potential risk factors associated with perceived exacerbation in psychological distress among Israelis due to the Russo-Ukrainian War. Specifically, we assessed how vulnerability factors such as previous traumatic exposure, having relatives and friends affected by the war, media exposure, having a Holocaust familial background, lower levels of resilience, and probable posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) are associated with perceived exacerbation in psychological distress. A random sample of 845 Israeli Jews aged 18-75 who reported exposure to at least one traumatic event participated in the study. Univariate logistic regression showed that Holocaust familial background, previous exposure to trauma, media exposure to the Russo-Ukrainian War, and probable diagnosis of PTSD or CPTSD are the main factors associated with perceived exacerbation in psychological distress. These results suggest that various traumatic factors associate with perceived higher psychological vulnerability to international conflicts, even when there is no direct personal threat. Practitioners should be aware of these factors among individuals exposed to trauma.

Investigating the latent structure of the International Trauma Questionnaire to assess ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD in an adult civilian sample during the Ukraine war

The symptom structure of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) and the validity of the International Trauma Questionnaire (ITQ) are yet to be tested among civilians in an active war zone. The present investigation examined the factor structure of the ITQ, the internal consistency of observed scores, and their associations with demographic characteristics and war-related experiences using a nationwide sample of 2,004 adults from the general population of Ukraine approximately 6 months after the full-scale Russian invasion in 2022. Overall, rates of endorsement across all symptom clusters were high. The mean total number of war-related stressors reported was 9.07 (SD = 4.35, range: 1-26). Internal reliability was good for all six ITQ subscales, Cronbach's αs = .73-.88, and the correlated six-factor model was found to provide the best representation of the latent structure of the ITQ in the present sample based on fit indices. There was evidence of a dose-response relationship, with increasing scores on all symptom clusters associated with higher total reported war-related stressors.

Poverty, Somatisation Tendency and Potency in Low-Income Adolescent Groups of India and Israel: Explorations from the Field

Poverty increases vulnerability towards somatisation and influences the sense of mastery and well-being. The present study on adolescents living in relative poverty in a high-income group country (Israel) and a low-middle-income group country (India) explored the nature of somatisation tendency (ST) and its relationship with potency and perception of poverty (PP). Potency, a buffer against stress-induced negative health effects, was hypothesized to be negatively related to ST and mediate the link between PP and ST. Purposive sampling was used to collect questionnaire-based data from community youth (12-16 years) of two metropolitan cities-Kolkata (India, N = 200) and Tel-Aviv (Israel, N = 208). The nature of ST, PP and potency was analysed using descriptive and inferential statistics and correlation-regression statistics and mediation analysis were used to understand the relationship among them. A clinically significant level of ST was reported by both Indian and Israeli youth experiencing 5-7 somatic symptoms on average. Potency was found to be a significant predictor of ST in both countries (p < 0.05) and emerged as a significant mediator (p < 0.001) in the PP and ST relationship among Indian adolescents. The present study highlights potency as a protective buffer in economically vulnerable community adolescents and re-establishes a high prevalence of ST among them, irrespective of their country's global economic position.

Why We Need a Developmentally Appropriate Trauma Diagnosis for Children: a 10-Year Update on Developmental Trauma Disorder

Developmental Trauma Disorder (DTD) was proposed almost two decades ago as a psychiatric diagnosis for children who have been traumatically victimized and whose attachment bonding with primary caregivers has been compromised. DTD was designed to complement and extend post-traumatic stress disorder (PTSD) by addressing forms of trauma-related biopsychosocial dysregulation not included in PTSD, many of which are attributed to other psychiatric disorders. In the past decade, evidence from clinician surveys and research field trial studies has provided evidence of DTD's validity and potential clinical utility. The growing evidence base for DTD is summarized and clinical rationales for the proposed DTD symptoms are described. DTD shows promise as a developmentally-attuned traumatic stress diagnosis for traumatized children.

As simple as possible, but not simpler: Revisiting the International Trauma Questionnaire (ITQ) complex PTSD items omitted in the shortened version

BACKGROUND

The risks of oversimplification of the symptomatology of Complex PTSD (CPTSD) have been highlighted in the literature.

OBJECTIVE

To re-examine 10 items representing disturbances in self-organization (DSO) that were deleted from the original 28-item version of the International Trauma Questionnaire (ITQ) when creating the current 12-item version.

PARTICIPANTS AND SETTING

An online convenience sample of 1235 MTurk users.

METHODS

Online survey comprising the fuller 28-item previous version of the ITQ, Adverse Childhood Experiences (ACEs) questionnaire, and PTSD Checklist for DSM-5 (PCL-5).

RESULTS

First, averaged endorsement of the 10 omitted items was lower than the 6 retained DSO items (d' = 0.34). Second, the 10 omitted DSO items accounted for incremental variance over and correlated equivalently to the 6 retained items with the PCL-5. Third, only the 10 omitted DSO items (r_-part = 0.12) while not the 6 retained DSO items (r_-part = -0.01) independently predicted ACE scores and, eight of these ten omitted DSO items differentiated higher ACE scores even among the subset of 266 participants who endorsed all 6 of the retained DSO items, most with medium effect sizes. Fourth, exploratory principal axis factor analysis differentiated two latent variables within the fuller set of 16 DSO symptoms, with the strongest indicators of the second factor, namely uncontrollable anger, recklessness, derealization, and depersonalization, being unmeasured within the 6 retained DSO items. Moreover, scores on both factors independently predicted both PCL-5 and ACE scores.

CONCLUSIONS

There are conceptual and pragmatic advantages to revisiting a more content-valid and comprehensive conceptualization of CPTSD and DSO, partially as may be measured by the recently deleted items from the original and fuller length ITQ.

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.

Refuting the myth of a 'tsunami' of mental ill-health in populations affected by COVID-19: evidence that response to the pandemic is heterogeneous, not homogeneous

BACKGROUND

The current study argues that population prevalence estimates for mental health disorders, or changes in mean scores over time, may not adequately reflect the heterogeneity in mental health response to the COVID-19 pandemic within the population.

METHODS

The COVID-19 Psychological Research Consortium (C19PRC) Study is a longitudinal, nationally representative, online survey of UK adults. The current study analysed data from its first three waves of data collection: Wave 1 (March 2020, N = 2025), Wave 2 (April 2020, N = 1406) and Wave 3 (July 2020, N = 1166). Anxiety-depression was measured using the Patient Health Questionnaire Anxiety and Depression Scale (a composite measure of the PHQ-9 and GAD-7) and COVID-19-related posttraumatic stress disorder (PTSD) with the International Trauma Questionnaire. Changes in mental health outcomes were modelled across the three waves. Latent class growth analysis was used to identify subgroups of individuals with different trajectories of change in anxiety-depression and COVID-19 PTSD. Latent class membership was regressed on baseline characteristics.

RESULTS

Overall prevalence of anxiety-depression remained stable, while COVID-19 PTSD reduced between Waves 2 and 3. Heterogeneity in mental health response was found, and hypothesised classes reflecting (i) stability, (ii) improvement and (iii) deterioration in mental health were identified. Psychological factors were most likely to differentiate the improving, deteriorating and high-stable classes from the low-stable mental health trajectories.

CONCLUSIONS

A low-stable profile characterised by little-to-no psychological distress ('resilient' class) was the most common trajectory for both anxiety-depression and COVID-19 PTSD. Monitoring these trajectories is necessary moving forward, in particular for the ~30% of individuals with increasing anxiety-depression levels.

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.

Mechanisms by which adverse childhood experiences, other traumas and PTSD influence the health and well-being of individuals with eating disorders throughout the life span

BACKGROUND

Multiple published sources from around the world have confirmed an association between an array of adverse childhood experiences (ACEs) and other traumatic events with eating disorders (EDs) and related adverse outcomes, including higher morbidity and mortality.

METHODS

In keeping with this Special Issue's goals, this narrative review focuses on the ACEs pyramid and its purported mechanisms through which child maltreatment and other forms of violence toward human beings influence the health and well-being of individuals who develop EDs throughout the life span. Relevant literature on posttraumatic stress disorder (PTSD) is highlighted when applicable.

RESULTS

At every level of the pyramid, it is shown that EDs interact with each of these proclaimed escalating mechanisms in a bidirectional manner that contributes to the predisposition, precipitation and perpetuation of EDs and related medical and psychiatric comorbidities, which then predispose to early death. The levels and their interactions that are discussed include the contribution of generational embodiment (genetics) and historical trauma (epigenetics), social conditions and local context, the ACEs and other traumas themselves, the resultant disrupted neurodevelopment, subsequent social, emotional and cognitive impairment, the adoption of health risk behaviors, and the development of disease, disability and social problems, all resulting in premature mortality by means of fatal complications and/or suicide.

CONCLUSIONS

The implications of these cascading, evolving, and intertwined perspectives have important implications for the assessment and treatment of EDs using trauma-informed care and trauma-focused integrated treatment approaches. This overview offers multiple opportunities at every level for the palliation and prevention of EDs and other associated trauma-related conditions, including PTSD.

Complex PTSD in Chinese Adolescents Exposed to Childhood Trauma: A Latent Profile Analysis

Although numerous studies have supported the idea that complex posttraumatic stress disorder (CPTSD) is a distinct disorder from posttraumatic stress disorder (PTSD) and demonstrated that childhood interpersonal trauma is an important risk factor for CPTSD, few studies have examined the validity of CPTSD in adolescents, especially in non-Western contexts. Moreover, the question of which form of child maltreatment plays the most important role in predicting CPTSD, and how CPTSD is associated with psychological health, physical health, and social function among adolescents, is not clear. The present study used a Chinese high school student sample with childhood trauma experiences (N = 395) to address these questions. Latent profile analysis indicated that there were four subgroups in our sample: Low symptoms (54.43%), Disturbance of self-organization (DSO, 18.99%), PTSD (15.95%), and CPTSD (10.63%). Further analysis revealed that emotional abuse was an important risk factor for CPTSD. In addition, the CPTSD class showed the highest levels of depression, anxiety, and stress, as well as the lowest levels of life satisfaction and physical health. This study revealed that CPTSD is a distinct disorder from PTSD in Chinese adolescents exposed to childhood trauma. It provides evidence that emotional abuse might be an important risk factor for CPTSD, and demonstrates that CPTSD is accompanied by serious psychological and physical consequences in adolescents. We suggest that parents and educators should focus more on adolescents' emotional needs, avoid using negative ways such as verbal violence to express love, and pay more attention to adolescents' DSO symptoms in parenting, teaching practices and clinical interventions.

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.

Validation of the International Trauma Questionnaire-Child and Adolescent Version (ITQ-CA) in a Chinese mental health service seeking adolescent sample

BACKGROUND

The International Trauma Questionnaire-Child and Adolescent version (ITQ-CA) is a self-report measure that assesses posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) based on the diagnostic formulation of the 11th version of the International Classification of Diseases (ICD-11). This study aimed to provide a Chinese translation and psychometric evaluation of the ITQ-CA using a sample of mental-health service seeking adolescents in Mainland China.

METHODS

The ITQ-CA was translated and back-translated from English to simplified Chinese and finalized with consensus from an expert panel. Adolescents ages 12-17 were recruited via convenience sampling from an outpatient psychiatric clinic in Mainland China. Participants completed the ITQ-CA; measures of four criterion variables (depression, anxiety, stress, adverse childhood experiences); and the PTSD Checklist for DSM-5 (PCL-5). Construct validity, concurrent validity, and comparison of PTSD caseness between ICD-11 and DSM-5 measures were assessed.

RESULTS

The final sample consisted of 111 Chinese adolescents (78% female; mean age of 15.23), all diagnosed with a major depressive disorder. Confirmatory factor analysis indicated the two-factor second-order model provided optimal fit. All criterion variables were positively and significant correlated with the six ITQ-CA symptom cluster summed scores. In the present sample, 69 participants (62.16%) met symptom criteria for ICD-PTSD or CPTSD using the ITQ-CA, and 73 participants (65.77%) met caseness for DSM-5 PTSD using the PCL-5. Rates of PTSD symptom cluster endorsement and caseness deriving from both diagnostic systems were comparable.

CONCLUSIONS

The Chinese ITQ-CA has acceptable psychometric properties and confers additional benefits in identifying complex presentations of trauma-related responses in younger people seeking mental health services.

Prevalence and predictors of ICD-11 posttraumatic stress disorder and complex PTSD in young people

OBJECTIVE

The prevalence, construct validity, risk factors and psychopathological correlates associated with ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as measured by the International Trauma Questionnaire for Children and Adolescents (ITQ-CA) were assessed in a sample of young people from Northern Ireland.

METHOD

Participants were trauma-exposed 11-19-year-olds (N = 507) who participated in the Northern Ireland Youth Wellbeing Prevalence Survey (YWS-NI, 2020). Factor mixture modelling (FMM) was used to test the latent structure of the ITQ-CA. Risk-factors and psychopathological correlates associated with latent class membership, and ICD-11diagnostic status, were also investigated.

RESULTS

More participants met the ITQ-CA criteria for CPTSD (3.4%, n = 44) than PTSD (1.5%, n = 19). A second-order FMM comprising a 'partial-PTSD class', a 'CPTSD class', a 'DSO class' and a 'low symptom endorsement class' was the best-fitting model. Younger age and cumulative trauma were risk factors for all trauma classes. Female gender and two or more violent traumas were significant predictors of the 'PTSD' and 'CPTSD' classes, while single sexual trauma was a significant predictor of the 'DSO' and 'CPTSD' classes. Two or more sexual traumas was a unique predictor of 'CPTSD class', while two or more vicarious traumas was a unique predictor of 'DSO class'. The 'CPTSD' class displayed the most notable comorbidity.

CONCLUSIONS

Findings indicate that CPTSD may be more prevalent than PTSD in children and young people. Support for the ICD-11 conceptualisation of CPTSD as representing a unique diagnostic construct was supported using FMM, with findings indicating trauma symptom class-specific risk profiles.

Developmental trauma: Conceptual framework, associated risks and comorbidities, and evaluation and treatment

Children exposed to adverse childhood experiences (ACEs) and pervasive interpersonal traumas may go on to develop PTSD and, in most cases, will further undergo a significant shift in their developmental trajectory. This paper examines contemporary research on Developmental Trauma (DT), which is inextricably linked to disruptions in social cognition, physiological and behavioral regulation, and parent-child attachments. Developmental trauma associated with early experiences of abuse or neglect leads to multi-faceted and longstanding consequences and underscores critical periods of development, complex stress-mediated adaptations, and multilevel, trans-theoretical influences in the diagnostic formulation and treatment of traumatized children, adolescents, and adults. Psychological and medical correlates of Developmental Trauma Disorder are considered, and directions for future research are discussed.

Theory Paper: Suggesting Compassion-Based Approaches for Treating Complex Post-traumatic Stress Disorder

Complex post-traumatic stress disorder (CPTSD) may develop following interpersonal and cumulative traumatic events, usually during early development. In addition to the core PTSD symptom profile, CPTSD presents emotional dysregulation symptoms that can be resistant to conventional treatments. Compassion-focused therapy (CFT) may be an effective intervention for addressing the more resistant symptoms in the emotional stabilisation phase of treatment rather than the trauma-processing phase. This paper explores the diagnostic validity and prevalence of CPTSD, treatment recommendations and the role of CFT in mediating shame and stabilising emotional dysregulation. We also evaluate current evidence utilising compassion-based interventions for the components of the CPTSD symptom profile and the viability of CFT as a whole. The novelty of CPTSD as a clinical condition means there is limited evidence regarding recommended treatment. Research into the efficacy of CFT and its suitability to target CPTSD’s symptom profile will contribute to the current gap in recommended treatment approaches for this condition.

Complex post-traumatic stress disorder

Complex post-traumatic stress disorder (complex PTSD) is a severe mental disorder that emerges in response to traumatic life events. Complex PTSD is characterised by three core post-traumatic symptom clusters, along with chronic and pervasive disturbances in emotion regulation, identity, and relationships. Complex PTSD has been adopted as a new diagnosis in the ICD-11. Individuals with complex PTSD typically have sustained or multiple exposures to trauma, such as childhood abuse and domestic or community violence. The disorder has a 1-8% population prevalence and up to 50% prevalence in mental health facilities. Progress in diagnostics, assessment, and differentiation from post-traumatic stress disorder and borderline personality disorder is reported, along with assessment and treatment of children and adolescents. Studies recommend multicomponent therapies starting with a focus on safety, psychoeducation, and patient-provider collaboration, and treatment components that include self-regulatory strategies and trauma-focused interventions.

[Diagnostic Criteria of PTSD in ICD10, ICD-11 and DSM 5: Relevance for expert opinion]

The diagnostic criteria of PTSD differ in the ICD-10, ICD-11 and DSM-5 manuals. The main diagnostic criteria are presented. The psychopathological findings obtained in a structured interview are essential for the diagnosis. Three case studies are used to illustrate the expert assessment in criminal law, accident insurance and victim compensation law.

Sexual Violence and Its Associated Psychosocial Effects in Ireland

Current data on the prevalence and psychosocial correlates of sexual violence in the Republic of Ireland is lacking, with the most recent sexual abuse and violence survey dating back to 2001. The current study sought to identify what proportion of Irish adults have experienced sexual violence, if there are sex differences in exposure to different forms of sexual violence, and to what extent different forms of sexual violence are associated with adverse psychosocial outcomes. To achieve these objectives, we carried out a nationally representative sample of Irish adults (N = 1,020) completed self-report measures of history of sexual violence and mental health. Results suggest that approximately one-in-three (34.4%) Irish adults experienced some form of sexual violence, including 14.8% who were sexually assaulted (raped) and 31.1% who were sexually harassed. Women were significantly more likely than men to have experienced all forms of sexual violence (ps < .001), with the exception of sexual assault by a parent or guardian. All forms of sexual violence were associated with an increased likelihood of serious mental health problems, with sexual assault by a parent/guardian associated with several other psychosocial outcomes in life, including education achievement, history of being taken into state care, salary, and employment status. Sexual violence is a common experience in the general population and women are disproportionately affected (1-in-2 women versus 1-in-5 men). Additional resources to increase mental health care among survivors of sexual violence is urgently needed. How our findings compare to Ireland's previous sexual abuse and violence survey and the implications of our findings for policy are discussed.

Posttraumatic stress disorder and complex posttraumatic stress disorder in UK police officers

BACKGROUND

We investigated work-related exposure to stressful and traumatic events in police officers, including repeated exposure to traumatic materials, and predicted that ICD-11 complex PTSD (CPTSD) would be more prevalent than posttraumatic stress disorder (PTSD). The effects of demographic variables on exposure and PTSD were examined, along with whether specific types of exposure were uniquely associated with PTSD or CPTSD.

METHODS

An online survey covering issues about trauma management, wellbeing and working conditions was disseminated via social media and official policing channels throughout the UK. In total, 10 401 serving police officers self-identified as having been exposed to traumatic events. Measurement of PTSD and CPTSD utilised the International Trauma Questionnaire.

RESULTS

The prevalence of PTSD was 8.0% and of CPTSD was 12.6%. All exposures were associated with PTSD and CPTSD in bivariate analyses. Logistic regression indicated that both disorders were more common in male officers, and were associated independently with frequent exposure to traumatic incidents and traumatic visual material, and with exposure to humiliating behaviours and sexual harassment, but not to verbal abuse, threats or physical violence. Compared to PTSD, CPTSD was associated with exposure to humiliating behaviours and sexual harassment, and also with lower rank and more years of service.

CONCLUSIONS

CPTSD was more common than PTSD in police officers, and the data supported a cumulative burden model of CPTSD. The inclusion in DSM-5 Criterion A of work-related exposure to traumatic materials was validated for the first time. Levels of PTSD and CPTSD mandate enhanced occupational mental health services.

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

BACKGROUND

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

OBJECTIVE

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

PARTICIPANTS AND SETTING

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

METHODS

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

RESULTS

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

CONCLUSION

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

Testing alternative models and predictive utility of the Death Anxiety Inventory-Revised: A COVID-19 related longitudinal population based study

The beginning of the COVID-19 pandemic had a profound effect on all aspects of daily life and triggered a swell of anxiety across the world. Some suggest this emotional response to the pandemic can be explained through death anxiety (DA), a transdiagnostic dimension associated with numerous psychological disorders. However, it remains unclear as to whether DA is a unidimensional or multidimensional construct. The primary aim of this study was to examine the underlying structure of the Death Anxiety Inventory-Revised (DAI-R; Tomás-Sábado et al., 2005) and assess its associations with mental health and demographic variables during the COVID-19 pandemic. To achieve these aims, we utilized data from Waves 1 (N = 2205: collected between March 23 and March 28, 2020) and 2 (N = 1406: collected between April 22 and May 1, 2020) of the COVID-19 Psychological Research Consortium (C19PRC), a multi-wave nationally representative study. Results showed that a 4-factor model provided the best fit to the data compared to a unidimensional and 4-factor second-order model. Further analyses showed that DA at Wave 1 was positively associated with somatic symptoms, paranoia, depression, anxiety, and traumatic stress symptoms at Wave 2, supporting previous research that suggests that the fear of death is predictive of psychopathology. Significantly, the factor labelled 'Thoughts about Death' at Wave 1 was the strongest predictor of the five main psychological variables at Wave 2, after statistically controlling for the other latent variables. These findings highlight the transdiagnostic nature of DA and support this important diagnostic construct becoming a measure of mental health more generally within the population. It is hoped that this research will shine a light on those suffering from DA and become a catalyst for increased therapeutic intervention, funding, and research in this area.

Testing both affordability-availability and psychological-coping mechanisms underlying changes in alcohol use during the COVID-19 pandemic

Two theoretical perspectives have been proffered to explain changes in alcohol use during the pandemic: the ‘affordability-availability’ mechanism (i.e., drinking decreases due to changes in physical availability and/or reduced disposable income) and the ‘psychological-coping’ mechanism (i.e., drinking increases as adults attempt to cope with pandemic-related distress). We tested these alternative perspectives via longitudinal analyses of the COVID-19 Psychological Consortium (C19PRC) Study data (spanning three timepoints during March to July 2020). Respondents provided data on psychological measures (e.g., anxiety, depression, posttraumatic stress, paranoia, extraversion, neuroticism, death anxiety, COVID-19 anxiety, intolerance of uncertainty, resilience), changes in socio-economic circumstances (e.g., income loss, reduced working hours), drinking motives, solitary drinking, and ‘at-risk’ drinking (assessed using a modified version of the AUDIT-C). Structural equation modelling was used to determine (i) whether ‘at-risk’ drinking during the pandemic differed from that recalled before the pandemic, (ii) dimensions of drinking motives and the psychosocial correlates of these dimensions, (iii) if increased alcohol consumption was predicted by drinking motives, solitary drinking, and socio-economic changes. The proportion of adults who recalled engaging in ‘at-risk’ drinking decreased significantly from 35.9% pre-pandemic to 32.0% during the pandemic. Drinking to cope was uniquely predicted by experiences of anxiety and/or depression and low resilience levels. Income loss or reduced working hours were not associated with coping, social enhancement, or conformity drinking motives, nor changes in drinking during lockdown. In the earliest stage of the pandemic, psychological-coping mechanisms may have been a stronger driver to changes in adults’ alcohol use than ‘affordability-availability’ alone.

The mediating role of complex posttraumatic stress and borderline pattern symptoms on the association between sexual abuse and suicide risk

BACKGROUND

The 11th revision of the International Classification of Diseases (ICD-11) includes a new diagnosis of complex posttraumatic stress disorder (CPTSD). There has been very little research investigating associations between CPTSD symptoms and suicide risk following sexual abuse. This and questions concerning similarities and differences between CPTSD and borderline personality disorder (BPD), led to the current study that aimed to explore indirect associations between sexual abuse and suicide risk through the symptoms of CPTSD and borderline traits.

METHODS

The study sample comprised 103 adults with a history of traumatic experiences (M_age = 32.64, SD_age = 9.36; 83.5% female). In total, 26.3% of the participants reported experiencing sexual abuse during their lifetime. The clinician-administered International Trauma Interview (ITI) was used for the assessment of ICD-11 CPTSD symptoms. Self-report measures were used for the evaluation of borderline pattern (BP) symptoms and suicide risk. Mediation analyses were performed to evaluate the mediating effects of CPTSD and BP symptoms for the association between sexual trauma and suicide risk.

RESULTS

In a parallel mediation model, CPTSD and BP symptoms mediated the association between sexual abuse and suicide risk, following adjustment for the covariates of age, gender, and whether the traumatic experience occurred in childhood or adulthood. Around 73% of participants who met diagnostic criteria for CPTSD reported previous suicide attempt(s).

CONCLUSIONS

Suicide risk assessment and intervention should be an important part of the management of victims of sexual abuse with CPTSD and BP symptoms.

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

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

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.

Validation of the International Trauma Interview (ITI) for the Clinical Assessment of ICD-11 Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) in a Lithuanian Sample

Background

The 11th revision of the International Classification of Diseases (ICD-11) includes a new diagnosis of complex posttraumatic stress disorder (CPTSD). The International Trauma Interview (ITI) is a novel clinician-administered diagnostic interview for the assessment of ICD-11 PTSD and CPTSD.

Objective

The aim of this study was to evaluate the psychometric properties of the ITI in a Lithuanian sample in relation to interrater agreement, latent structure, internal reliability, as well as convergent and discriminant validity.

Method

In total, 103 adults with a history of various traumatic experiences participated in the study. The sample was predominantly female (83.5%), with a mean age of 32.64 years (SD = 9.36). For the assessment of ICD-11 PTSD and CPTSD, the ITI and the self-report International Trauma Questionnaire (ITQ) were used. Mental health indicators, such as depression, anxiety, and dissociation, were measured using self-report questionnaires. The latent structure of the ITI was evaluated using confirmatory factor analysis (CFA). In order to test the convergent and discriminant validity of the ITI we conducted a structural equation model (SEM).

Results

Overall, based on the ITI, 18.4% of participants fulfilled diagnostic criteria for PTSD and 21.4% for CPTSD. A second-order two-factor CFA model of the ITI PTSD and disturbances in self-organization (DSO) symptoms demonstrated a good fit. The associations with various mental health indicators supported the convergent and discriminant validity of the ITI. The clinician-administered ITI and self-report ITQ had poor to moderate diagnostic agreement across different symptom clusters.

Conclusion

The ITI is a reliable and valid tool for assessing and diagnosing ICD-11 PTSD and CPTSD.

Posttraumatic stress disorder, complex PTSD and subtypes of loneliness among older adults

OBJECTIVES

Research examining the relationship between loneliness and Complex Posttraumatic Stress Disorder (CPTSD) is scarce, particularly among older adults. CPTSD includes the core symptoms of PTSD along with additional symptoms reflecting "disturbances in self-organisation" (DSO). This study examined the cross-sectional relationships between loneliness (emotional and social loneliness) and CPTSD symptoms (i.e., PTSD and DSO symptoms) in older adults.

METHODS

Structural equation modelling was used to examine these relationships in a nationally representative sample of US adults aged 60-70 years (n = 456).

RESULTS

Controlling for covariates, emotional loneliness was associated with PTSD (β = 0.31) and DSO (β = 0.57) symptoms whereas social loneliness was only associated with DSO symptoms (β = 0.25). The model explained 35.0% of the variance in PTSD symptoms and 71.3% in DSO symptoms.

CONCLUSION

These findings have important implications for treating and understanding PTSD/CPTSD and their correlates among older adults.

ICD-11 Posttraumatic Stress Disorder and Complex PTSD Among Hospital Medical Workers in China: Impacts of Wenchuan Earthquake Exposure, Workplaces, and Sociodemographic Factors

BACKGROUND

Previous studies address posttraumatic stress disorder (PTSD) following disasters as a public health issue. However, few studies investigate the long-term effect of disaster exposure on PTSD among hospital medical workers (HMWs).

OBJECTIVES

This study aimed to study the prevalence of ICD-11 PTSD and complex PTSD (CPTSD) among exposed and non-exposed HMWs 11 years after the Wenchuan earthquake in China, to identify the factors associated with PTSD and CPTSD scores, and to examine the factor structures of PTSD and CPTSD models.

METHODS

A cross-sectional study was conducted using a self-administered online questionnaire. Two thousand fifty-nine valid samples were collected from four hospitals in 2019. Descriptive statistical analysis, multivariate regression models, and confirmatory factor analysis (CFA) were performed.

RESULTS

The prevalence of PTSD and CPTSD was 0.58 and 0.34%, respectively. The unexposed group reported higher PTSD and CPTSD scores than the exposed group. The type of workplace and marital status were significantly associated with the PTSD and CPTSD scores of HMWs. The CFA results indicate that both the correlated first-order model and the correlated two-layer model were a good fit to explain the structure of PTSD and CPTSD.

CONCLUSION

These findings suggest that few HMWs who were exposed to the Wenchuan earthquake suffered from PTSD or CPTSD 11 years following the disaster. However, psychological support was still necessary for all HMWs, especially for unmarried HMWs who were Working in smaller hospitals. Further research is required to analyze mental health status using ICD-11 PTSD and CPTSD to provide ongoing evidence to help HWMs cope effectively with the challenges of future disasters.

Validation of the International Adjustment Disorder Questionnaire in Israel and Switzerland

The ICD-11 has introduced a new conceptualization of adjustment disorder (AjD) as a stress response syndrome with core symptoms of preoccupations and failure to adapt to the stressor. The current study aimed to assess the reliability and validity of the International Adjustment Disorder Questionnaire (IADQ) in two culturally distinct samples from Israel and Switzerland. Two samples were recruited in Israel (N = 1142) and Switzerland (N = 699) during the initial stages of the COVID-19 pandemic. Confirmatory factor analysis indicated that a correlated two-factor model provided an excellent fit to the Israeli and Swiss sample data. The IADQ scores correlated strongly with another measure of AjD symptoms, and with symptoms of depression, anxiety, acute stress, and negative emotions whereas correlations with posttraumatic stress disorder, complex posttraumatic stress disorder, and positive emotions were weaker. In the Swiss sample, 18.8% met diagnostic criteria for probable AjD and 10.2% in the Israeli sample. The current study provides the first evidence of the validity of the German and Hebrew versions of the IADQ and can be used for the screening of this debilitating condition.
