Structural equation modeling (SEM) offers a robust method for comparing latent variables across different groups. This approach is crucial for understanding group differences in complex constructs within research.

Area of Science:

  • Psychometrics
  • Statistical Modeling
  • Rehabilitation Research

Background:

  • Structural equation modeling (SEM) is a powerful statistical technique.
  • It allows for the analysis of complex relationships between observed and latent variables.
  • Testing for group differences on latent variables is essential in many research fields.

Purpose of the Study:

  • To illustrate the application of SEM for testing group mean differences on latent variables.
  • To demonstrate confirmatory factor analysis (CFA) within this framework.
  • To present methods for testing measurement invariance across groups.

Main Methods:

  • Utilizing structural equation modeling (SEM) for latent variable analysis.
  • Implementing confirmatory factor analysis (CFA) to establish measurement models.
