An examination of the use of exploratory and confirmatory factor analysis by researchers publishing in Personality and Social Psychology Bulletin over the previous 5 years is presented, along with a review of recommended methods based on the recent statistical literature. In the case of exploratory factor analysis, an examination and recommendations concerning factor extraction procedures, sample size, number of measured variables, determining the number of factors to extract, factor rotation, and the creation of factor scores are presented. These issues are illustrated via an exploratory factor analysis of data from the University of California, Los Angeles, Loneliness Scale. In the case of confirmatory factor analysis, an examination and recommendations concerning model estimation, evaluating model fit, sample size, the effects of non-normality of the data, and missing data are presented. These issues are illustrated via a confirmatory factor analysis of data from the Revised Causal Dimension Scale.
