ABSTRACT
Distinctions between Exploratory Factor Analysis (EFA) and Confinnatory Factor Analysis (CFA), and basic notions concerning their applications in the context of construct validation, were introduced in Chapter 4. Although there is no clear demarcation line between EFA and CFA (e.g., Cliff, 1987; Marradi, 1981; Nunnally, 1978), the two approaches differ in important ways.
