Summary

This study provides further evidence for the validity of the Toronto Alexithymia Scale (TAS). The TAS effectively measures the alexithymia construct by correlating meaningfully with other psychological measures.

Area of Science:

  • Psychology
  • Psychometrics

Background:

  • The Toronto Alexithymia Scale (TAS) has been previously developed and its reliability and validity documented.
  • Further evaluation of the TAS's construct validity is warranted.

Purpose of the Study:

  • To further evaluate the construct validity of the Toronto Alexithymia Scale (TAS).
  • To assess the theoretical meaningfulness of TAS correlations with other psychological measures.

Main Methods:

  • Study I: 117 university students completed the TAS and the Short Imaginal Processes Inventory.
  • Study II: 74 students completed the TAS, alongside measures of ego strength, anger expression, and physical symptoms.

Main Results:

  • In both studies, correlations between the TAS and other psychological measures showed theoretically meaningful convergence and divergence.

  • These patterns support the construct validity of the TAS.

    • Conclusions:

    • The findings provide additional evidence for the validity of the Toronto Alexithymia Scale (TAS).
    • The results support the continued use and understanding of the alexithymia construct.
