This program provides essential calculations for factor pattern invariance, enabling researchers to compare factor structures across different samples with confidence.

  • Pros

    • Calculates coefficient of congruence (Rc).
    • Calculates chi-square goodness of fit.
    • Calculates salient variable similarity index.
    • Supports comparison of factor loadings.
    • Requires same variables and factoring methods.

  • Cons

    • Requires identical variables and factoring methods.
    • Chi-square requires number of subjects per factor.
    • Salient index needs user-specified salience value.

Developer’s Description

By Ed & Psych Associates
Calculate three indices of factor pattern invariance.
This program calculates three indices of factor pattern invariance: coefficient of congruence (Rc); chi-square goodness of fit; and salient variable similarity index. All three require that the same variables and factoring methods be used in separate samples. The Rc can be calculated from the matching factor loadings alone. The chi-square goodness of fit method also requires that the number of subjects in each factor be entered. The salient variability similarity index requires the matching factor loadings and a user-specified value for salience.
