Implication

This research proposes an improved comparison standard for discriminant validation in multi-item scales, highlighting systematic approaches. It aims to address weaknesses in existing criteria.

Key Points

  • The research presents three requirements for effective discriminant validation criteria, enhancing the empirical distinctiveness of constructs.
  • A detailed case study illustrates the strengths of the proposed systematic procedure, integrating congeneric reliability and measurement error.
  • This approach overcomes weaknesses of the Fornell and Larcker criterion, providing continuous support for discriminant validity.
  • The study includes example code and an online tool for implementing the new procedure, facilitating its application in future research.
