N2 - 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.
