Factor Loading Estimation Error and Stability Using Exploratory Factor Analysis
Sass, Daniel A.
Educational and Psychological Measurement, v70 n4 p557-577 Aug 2010
Exploratory factor analysis (EFA) is commonly employed to evaluate the factor structure of measures with dichotomously scored items. Generally, only the estimated factor loadings are provided with no reference to significance tests, confidence intervals, and/or estimated factor loading standard errors. This simulation study assessed factor loading estimation error under several experimental conditions and whether hypothesis testing and/or confidence intervals should be employed. Results revealed that the promax rotation performed well with small interfactor correlations and "simple structure" data, whereas varimax only performed well with orthogonal factors. Neither rotation method performed well with larger interfactor correlations or "approximate simple structure" data. An explanation of these results is provided. (Contains 3 tables and 6 figures.)
