Fig. 2 — Confirmatory factor analysis. The factor structure of WHODAS 2.0 according to the confirmatory factor analysis with one general disability factor and the six domains as second-order factors. The model fit: Chi-Square (458, N = 3100) = 10,244.5, p < 0.0001; RMSEA = 0.08; 90% CI 0.082–0.084; SRMR = 0.06; CFI = 0.89; and TLI = 0.88. The first level consisted of a general disability factor and the second level consisted of the six domains of the instrument. The four items corresponding to the Life activities: work/study domain are excluded, hence WHODAS 2.0 with 32-items is used for the confirmatory factor analysis
