Abstract

This chapter provides an overview of exploratory factor analysis (EFA) from an applied perspective. We start with a discussion of general issues and applications, including definitions of EFA and the underlying common factors model. We briefly cover history and general applications. The most substantive part of the chapter focuses on six steps of EFA. More specifically, we consider variable (or indicator) selection (Step 1), computing the variance–covariance matrix (Step 2), factor-extraction methods (Step 3), factor-retention procedures (Step 4), factor-rotation methods (Step 5), and interpretation (Step 6). We include a data analysis example throughout (with example code for R), with full details in an online supplement. We hope the chapter will provide helpful guidance to applied researchers in the social and behavioral sciences.
