Table 4 Confirmatory factor analysis goodness of fit statistics

From: A 5 item version of the Compliance Questionnaire for Rheumatology (CQR5) successfully identifies low adherence to DMARDs

Model χ2 Satorra-Bentler χ2 RMSEA (90% CI) NFI CFI RMR
CQR11 465.34** 172.05** 0.11 (0.095;0.13) 0.94 0.95 0.094
CQR5 56.64** 14.14* 0.089 (0.036;0.15) 0.98 0.99 0.054
  1. ** = p < 0.001.
  2. * = p < 0.05.
  3. For the purposes of this analysis, the following fit indices were used with the respective cut off values as recommended by Hu and Bentler [21]. Absolute fit class; χ2 and Satorra-Bentler Scaled χ2 because the latter adjusts for polychoric correlation (p > .05), Root Mean square Residual (RMR; <.08). Parsimony fit class; Root Mean Square Error of Approximation (RMSEA; <.08). Comparative fit class; Normed Fit Index (NFI; >.9) and Comparative Fit Index (CFI; >.9).
