This article is a brief commentary in response to “Gundy, C.M., Fayers, P.M., Groenvold, M., Petersen, M. Aa., Scott, N.W., Sprangers, M.A.J., Velikov, G., Aaronson, N.K. (2011). Comparing higher-order models for the EORTC QLQ-C30. Quality of Life Research, doi:10.1007/s11136-011-0082-6.” The commentary argues that approximate goodness-of-fit indexes cannot be used to salvage confirmatory factor models rejected by the Chi-square test of exact fit. Instead, rigorous diagnostic procedures should be used to identify and resolve the particular sources of model misspecification.
