It provides a global measure of disability and 7 domain-specific scores. The aim of this study was to assess WHODAS-2 conceptual model and metric properties in a set of chronic and prevalent clinical conditions accounting for a wide scope of disability in Europe. Methods 1 119 patients with one of 13 chronic conditions were recruited in 7 European centres. Participants were clinically evaluated and administered the WHODAS-2 and the SF-36 at baseline 6 weeks and 3 months of follow-up. The latent structure was explored and confirmed by factor analysis FA . Reliability was assessed in terms of internal consistency Cronbach s alpha and reproducibility intra-class correlation coefficients ICC . Construct validity was evaluated by correlating the WHODAS-2 and SF-36 domains and comparing known groups based on the clinical-severity and work status. Effect size ES coefficient was used to assess responsiveness. To assess reproducibility and responsiveness subsamples of stable at 6 weeks and improved after 3 moths patients were defined respectively according to changes in their clinical-severity. Results The satisfactory FA goodness of fit indexes confirmed a second order factor structure with 7 dimensions and a global .
