Abstract

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.

  • Empirically validated cPTSD interview guides have been developed, including the International Trauma Questionnaire (ITQ) for adults and children, and the Developmental Trauma Disorder Semi-structured Interview (DTD-SI) for children and adolescents.

    “Empirically validated cPTSD interview guides have been developed, including the International Trauma Questionnaire (ITQ) for adults [21] and children [66], and the Developmental Trauma Disorder Semi-structured Interview (DTD-SI) for children and adolescents [46, 174].”

    The Methods (Measures) say the study used the adult ITQ, an 18-item self-report measure, with children. The Discussion reports first empirical evidence of its applicability as a screening instrument for children. This supports the child-validation part attributed to this citation, but not the description of the ITQ as an interview guide developed for children. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
