This study introduces a Windows program for measurement invariance analysis using unrestricted factor analysis. It addresses limitations of restricted factor analysis, particularly with large datasets, offering a practical solution for researchers.

Area of Science:

  • Psychometrics
  • Statistical Software
  • Social Sciences Research Methods

Background:

  • Measurement invariance is crucial for comparing constructs across populations.
  • Restricted factor analysis is a popular method but faces convergence issues with large samples.
  • Existing software limitations hinder practical application of measurement invariance testing.

Purpose of the Study:

  • To describe a new Windows program for analyzing measurement invariance.
  • To provide an alternative to restricted factor analysis, especially for large datasets.
  • To facilitate robust invariance testing using unrestricted factor analysis.

Main Methods:

  • The program utilizes unrestricted factor analysis.
  • It assesses invariance based on difficulties, discriminations, and residual variances.

  • Bootstrap resampling is employed for statistical significance testing.

    • Main Results:

    • The program offers a viable alternative when restricted factor analysis fails.
    • It successfully handles large sample sizes common in online surveys.
    • A real-life example demonstrates the program's practical utility and effectiveness.

    Conclusions:

    • The developed program provides a practical solution for measurement invariance analysis.
    • It overcomes limitations of restricted factor analysis, enhancing research applicability.
    • The tool supports reliable cross-population comparisons in psychological and social sciences.
