Improving the evaluation of model fit in confirmatory factor analysis: A commentary on 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

摘要

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 Chisquare test of exact fit. Instead, rigorous diagnostic procedures should be used to identify and resolve the particular sources of model misspecification.
