Is exploratory factor analysis necessary?
Exploratory factor analysis is essential to determine underlying constructs for a set of measured variables.
Does factor analysis measure validity?
It then focuses on factor analysis, a statistical method that can be used to collect an important type of validity evidence. Factor analysis helps researchers explore or confirm the relationships between survey items and identify the total number of dimensions represented on the survey.
What is the difference between exploratory and confirmatory factor analysis?
In exploratory factor analysis, all measured variables are related to every latent variable. But in confirmatory factor analysis (CFA), researchers can specify the number of factors required in the data and which measured variable is related to which latent variable.

How is scale development and validation using EFA and CFA?
Scale development and validation using EFA and CFA is a complex process involving many choices regarding (a) data screening procedures; (b) model fit statistics; (c) statistical tests for comparing competing models; and (d) the next appropriate step in the scale development and validation process. It is difficult to
Can you bypass EFA in a questionnaire validation process?
The validation process mostly begins with a AFE and ends with a CFA. My question is the following: is it possible, if one has strong theoretical arguments to validate the hypothesised latent structure of the questionnaire, to bypass the EFA stage in the validation process?
What’s the difference between a CFA and an EFA?
CFA and EFA are both methods of factor analysis. It is said that EFA extracts a factor structure from the data whereas CFA is used to test if a factor structure fits the data (or in other words to test a hypothesis). Given this, why would I want to do CFA instead of EFA if the latter is able to determine…
What’s the difference between EFA and confirmatory factor analysis?
The exploratory factor analysis is a statistical method that is used to identify latent variables that underlie a set of a larger number of manifest variables. The term exploratory factor analysis (EFA) stems from the need to differentiate from the confirmatory factor analysis (CFA).
