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

Symptom structure of ICD-11 Complex Posttraumatic Stress Disorder (CPTSD) in trauma-exposed foster children: examining the International Trauma Questionnaire – Child and Adolescent Version (ITQ-CA)

Background: The 11th edition of the International Classification of Diseases (ICD-11) introduces Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD) as two distinct trauma-related disorders. Numerous studies support the proposed symptom structure of ICD-11 CPTSD in adults, but only a few studies have examined CPTSD symptom structure in children, reporting diverging results. To assess ICD-11 CPTSD in children, the International Trauma Questionnaire (ITQ) was recently adapted for children and adolescents (ITQ-CA), with no validated German version available yet. Objective: This study aimed (1) to test the symptom structure of ICD-11 CPTSD in a sample of trauma-exposed foster children using the ITQ-CA, and (2) to examine the concurrent, convergent and discriminant validity of the German ITQ-CA. Method: Altogether, 161 Austrian foster children completed a set of standardized measures, resulting in a final sample of 135 trauma-exposed foster children meeting the inclusion criteria. Psychometric properties of the ITQ-CA were assessed using confirmatory factor analysis (CFA), bivariate correlations and multivariate regression. Results: CFA supported ICD-11 CPTSD symptom structure in children as a two-factor higher-order model with PTSD and Disturbances in Self-Organization (DSO) as correlated factors with very good model fit, while a one-factor higher-order model also fitted the data very well. High factor loadings and excellent levels of internal reliability evidenced the psychometric adequacy of the ITQ-CA. Concurrent and convergent validity were evidenced by high correlations between ITQ-CA scales and criterion variables (PTSD symptoms, depression, anxiety, dissociation, lifetime traumatization). Discriminant validity was partly supported by PTSD and DSO being differently predicted by exogenous criterion variables. Conclusions: CPTSD symptom structure in children is in support of the ICD-11 conceptualization. The reliability and validity of the German ITQ-CA are evidenced for the first time, identifying it as an easy-to-use screening instrument to assess ICD-11 PTSD and CPTSD in children. Further implications and areas for upcoming studies are discussed

Using a delphi process to develop an effective train-the-trainers program to train health and social care professionals throughout Europe

Research has shown that developing a Train-the-Trainers (TTT) program is important if agencies are to implement guidelines, but the most effective way to deliver a TTT program remains unanswered. This article presents data from a 3-round Internet-based Delphi process, which was used to help develop consensus-based guidelines for a TTT programme to deliver to health and social care professionals throughout Europe a curriculum on traumatic stress. In Round 1, 74 experts rated the importance of statements relating to the TTT field and then reassessed their scores in the light of others' responses in subsequent rounds. Forty-one (67%) of 61 statements achieved consensus (defined as having a mean score >7 or < 3 on the 0–9 rating scales used and 70% of participants scoring 7 and above or 3 and below) for inclusion. Key TTT components included interactive and practical presentations, delivery to groups of 7–12 people over 2 days, external and local expert facilitation, course manuals, refresher courses, and supervision. The Delphi process allowed a consensus to be achieved in an area in which there are limitations in the current evidence

Stressors, coping and symptoms of adjustment disorder in the course of the COVID-19 pandemic – study protocol of the European Society for Traumatic Stress Studies (ESTSS) pan-European study

Background: During the current COVID-19 pandemic, the people in Europe are exposed to self-isolation, quarantine, job loss, risk of contracting COVID-19, or grief of loved ones. Such a complex array of stressors may lead to symptoms of adjustment disorder or posttraumatic stress disorder. This research protocol describes a study launched by the European Society of Traumatic Stress Studies (ESTSS) to investigate the impact of the COVID-19 pandemic on symptoms of adjustment disorder across European countries. Objective: The longitudinal online cohort study aims (1) to explore psychosocial reactions to the COVID-19 pandemic across ten European countries; (2) to examine the relationships between risk and resilience factors, stressors and symptoms of adjustment disorder during the pandemic; and (3) to investigate whether these relationships are moderated by coping behaviours. Method: In ten countries (Austria, Croatia, Georgia, Germany, Italy, Lithuania, Netherlands, Poland, Portugal, and Sweden), between 1,000 and 2,000 participants will be recruited, depending on the size of the country. Participants will be assessed at two timepoints with a six-month interval. Following a conceptual framework based on the WHO’s social framework of health, an assessment of risk and resilience factors, COVID-19 related stressors and pandemic-specific coping behaviours will be measured to estimate their contribution to symptoms of adjustment disorder. The Adjustment Disorder New Module 8 (ADNM-8) will be used to assess symptoms of adjustment disorder. As a secondary measure, symptoms of posttraumatic stress disorder will be measure using the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5). Data analysis: The relative contribution of risk factors, resilience factors, and stressors on symptoms of adjustment disorder or symptoms of posttraumatic stress disorder will be estimated using multilevel analysis. To determine the moderating effects of different types of coping behaviours on these relationships, a multilevel mediation analysis will be carried out

Validation of ICD‐11 PTSD and complex PTSD in foster children using the International Trauma Questionnaire

Objective: ICD ‐11 introduces post‐traumatic stress disorder (PTSD ) and complex PTSD (CPTSD ) as two distinct trauma‐related disorders. Using the International Trauma Questionnaire (ITQ ) as disorder‐specific measure, this study is the first to examine the factorial and construct validity of ICD ‐11 PTSD , CPTSD and the ITQ s’ applicability in children. Methods: Two hundred and eight Austrian foster children completed a set of standardized measures. Excluding participants who reported not having experienced any kind of trauma, a final sample of 136 children completed the ITQ . Factorial and construct validity of ICD ‐11 CPTSD and psychometric properties of ITQ scales were assessed by factor analysis and latent class analysis. Results: Confirmatory factor analysis supported the two‐factor higher‐order model of ICD ‐11 CPTSD in children by high factor loadings and excellent model fit. Reliability and regression analysis evidenced psychometric adequacy and discriminant validity of ITQ scales. Latent class analysis substantiated construct validity of ICD ‐11 CPTSD , identifying a CPTSD (22.8%), PTSD (31.6%) and low symptoms class (45.6%). The CPTSD class showed highest rates of childhood trauma, comorbid psychopathology and functional impairment. Conclusion: Factorial and construct validity of ICD ‐11 CPTSD was evidenced in children for the first time using precise descriptions of ICD ‐11 symptom content, supporting the reliability and validity of the ITQ in children.© 2019 The Author
