What is a multiple group analysis?
The multi-group analysis allows to test if pre-defined data groups have significant differences in their group-specific parameter estimates (e.g., outer weights, outer loadings and path coefficients). SmartPLS provides outcomes of three different approaches that are based on bootstrapping results from every group.
What does factorial invariance mean?
Factorial invariance is a concept applied in the context of psychometric analysis of questionnaires. The concept postulates that the psychometric properties of a questionnaire, used either by multiple groups or by the same group over time, have to be identical to ensure an unbiased comparison of factor means.
How is Multigroup SEM used to test for weak factorial invariance?
A multigroup structural equation modeling approach was used to compare men and women on the factor loadings of the positive and negative affect scale. To test for weak factorial invariance (Meredith, 1993) across groups, the chi-square from a model with all parameters allowed to be unequal across groups was compared
How to calculate configural invariance for multiple groups?
Measurement invariance: Step 1: Configural invariance Same factor structure in each group First, fit model separately in each group Second, fit model in multiple group but let all parameters vary freely in each group No latent mean difference is estimated Configural invariance
How to test for dimensional invariance across groups?
Rerun the Exploratory Factor Analysis (EFA) model separately for both groups. If different indicator variables load onto the constructs across groups, we go no further. The construct is inconsistent across groups. This is known as testing for dimensional invariance.
