At the time of writing, SPSS is limited to EFA only.

Software is usually required to perform confirmatory factor analysis. You specify factor loadings as a set of regression statements from the factor to the observed variables.” With EFA, it’s possible to specify a few factors and a particular rotation you can then compare your results to see if they fit your model. “The predominant CFA approach today is to consider CFA as a special case of structural equation modeling (SEM).

If the model is unacceptable, consider performing Explanatory Factor Analysis.Īccording to IBM, EFA has overtaken CFA as a means of Factor Analysis. Determine if the model you chose is working.Perform initial data analysis to check for issues like missing data, collinearity or outliers.Determine if unique value are possible for the population parameter estimation.For example, you might choose a diagram or equations. Perform a literature review to help you choose an appropriate model.Implementing Confirmatory Factor Analysisĭiane Suhr, PhD, on the SAS website, suggests the following steps: Although it is technically applicable to any discipline, it is typically used in the social sciences. For example, CFA can answer questions like “Does my ten question survey accurately measure one specific factor?”. With Confirmatory Factor Analysis you can specify the number of factors required. If you want to perform hypothesis testing, use CFA.ĮFA provides information about the optimal number of factors required to represent the data set.If you want to explore patterns, use EFA.It is similar to Exploratory Factor Analysis. The Kaiser-Meyer-Olkin test checks to see if your data is suitable for FA.Ĭonfirmatory Factor Analysis allows you to figure out if a relationship between a set of observed variables (also known as manifest variables) and their underlying constructs exists. Instructions for Stata can be found here.The new data sets are merged into a unique matrix and a second, global PCA is performed.įactor Analysis is an extremely complex mathematical procedure and is performed with software.This gives an eigenvalue, which is used to normalize the data sets. Principal Component Analysis is performed on each set of data.The two steps performed in Multiple Factor Analysis are: For example, you might have a student health questionnaire with several items like sleep patterns, addictions, psychological health, or learning disabilities. This subset of Factor Analysis is used when your variables are structured in variable groups. A factor loading of zero would indicate no effect. The closer factors are to -1 or 1, the more they affect the variable. Factor loadings are similar to correlation coefficients in that they can vary from -1 to 1. The factors that affect the question the most (and therefore have the highest factor loadings) are bolded. In a simple example, imagine your bank conducts a phone survey for customer satisfaction and the results show the following factor loadings: Variable Not all factors are created equal some factors have more weight than others.
