RESUMO
Background: In 2013, the Clinician-Administered PTSD Scale, the golden standard to assess PTSD, was adapted to the DSM-5 (CAPS-5). Objective: This project aimed to develop a clinically relevant Dutch translation of the CAPS-5 and to investigate its psychometric properties. Method: We conducted a stepped translation including Delphi rounds with a crowd of 44 Dutch psychotrauma experts and five senior psychotrauma experts. Using partial crowd-translations, two professional translations and the official Dutch translation of the DSM-5, each senior expert aggregated one independent translation. Consensus was reached plenary. After back-translation, comparison with the original CAPS-5 and field testing, a last round with the senior experts resulted in the final version. After implementation clinicians conducted CAPS-5 interviews with 669 trauma-exposed individuals referred for specialized diagnostic assessment. Reliability of the Dutch CAPS-5 was investigated through internal consistency and interrater reliability analyses, and construct validity through confirmatory factor analysis (CFA). Results: CAPS-5 total severity score showed high internal consistency (α = .90) and interrater reliability (ICC = .98, 95% CI: .94-.99). CAPS-5 diagnosis showed modest interrater reliability (kappa = .59, 95% CI: .20-.98). CFA with alternative PTSD models revealed adequate support for the DSM-5 four-factor model, but a six-factor (Anhedonia) model fit the data best. Conclusions: The Dutch CAPS-5 is a carefully translated instrument with adequate psychometric properties. Current results add to the growing support for more refined (six and seven) factor models for DSM-5 PTSD indicating that the validity and clinical implications of these models should be objective of further research.
Antecedentes: En el año 2013 la Escala para el TEPT Aplicada por el Clínico, la prueba estándar para evaluar el TEPT, fue adaptada al DSM-5 (CAPS-5).Objetivo: Este proyecto apuntó a desarrollar una traducción holandesa clínicamente relevante de la Escala para el TEPT Aplicada por el Clínico adaptada al DSM-5 (CAPS-5) e investigar sus propiedades psicométricas.Método: Realizamos una traducción escalonada, incluyendo fases del método Delphi con un grupo de 44 expertos holandeses en psicotrauma y cinco expertos de larga trayectoria en psicotrauma. Utilizando traducciones en grupo parciales, dos traducciones profesionales y la traducción holandesa oficial del DSM-5, cada experto experimentado sumó una traducción independiente. Se alcanzó un conceso pleno. Después de traducciones inversas, comparación con el CAPS-5 original y ensayo de campo, una última fase con los expertos experimentados resultó en la versión definitiva. Tras la implementación, los clínicos realizaron entrevistas aplicando CAPS-5 a 669 individuos expuestos a trauma referidos por evaluación diagnóstica especializada. Se investigó la fiabilidad del CAPS-5 holandés a través de consistencia interna y análisis de confiabilidad, y se estableció su validez a través de análisis factorial de tipo confirmatorio.Resultados: El puntaje de severidad total del CAPS-5 mostró alta consistencia interna (α = .90) y confiabilidad (ICC = .98, 95% IC: .94 - .99). El diagnóstico de CAPS-5 mostró una modesta confiabilidad (kappa = .59, 95% CI: .20 - .98). El análisis factorial de tipo confirmatorio con modelos alternativos de TEPT reveló un respaldo adecuado para el modelo de 4 factores del DSM-5, pero un modelo de 6 factores (Anhedonia) se ajusta mejor a los datos.Conclusiones: El CAPS-5 holandés es un instrumento cuidadosamente traducido con adecuadas propiedades psicométricas. Nuestros resultados se suman al respaldo creciente para modelos de factores (seis y siete) más refinados para el TEPT según el DSM-5, indicando que la validez y las implicaciones clínicas de estos modelos deberían ser objeto de futuras investigaciones.
RESUMO
To facilitate easily accessible screening for trauma-related symptoms, a web-based application called Smart Assessment on your Mobile (SAM) was developed. In this study, we examined whether SAM was able to accurately identify posttraumatic stress disorder (PTSD) and depression in adults. Eighty-nine referred police officers completed SAM, containing the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 (PCL-5) and the Depression Anxiety and Stress Scale (DASS-21), on their own device prior to a diagnostic interview where the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and Structured Clinical Interview for DSM-IV (SCID-I/P) were administered. Results showed a substantial agreement between SAM and the diagnostic interview in the assessment of PTSD and depression. An optimal trade-off between sensitivity (89%) and specificity (68%) levels was found at a cut-off score of 31 on the PTSD Checklist for DSM-5 (area under the curve = 0.845, 95% CI [0.765, 0.925], diagnostic odds ratio = 15.97). This is one of the first studies to support the validity and reliability of a mobile screener following trauma. SAM may facilitate screening for trauma-related symptoms on a large scale and could be a first step in a stepped-care model for trauma survivors to help identify individuals who need further diagnostics and care.
