Summary

Meta-interpretive reliability accurately assesses how well personality traits are conveyed in computer-based test interpretations (CBTI). This new method shows that the Karson Clinical Report has acceptable reliability for communicating personality scores.

Area of Science:

  • Psychological assessment
  • Measurement in psychology

Background:

  • Computer-based test interpretation (CBTI) relies on accurately communicating personality trait scores.
  • Meta-interpretive reliability is a novel method to assess this communication accuracy.

Purpose of the Study:

  • To evaluate the meta-interpretive reliability of the Karson Clinical Report (KCR).
  • To determine the accuracy of personality trait score communication in CBTI.

Main Methods:

  • A two-way repeated measures analysis of variance (ANOVA) design was employed.
  • 101 psychologists estimated personality trait scores from KCR examples based on the Sixteen Personality Factor Questionnaire (16PF).
  • Statistical analysis focused on Trait x Protocol interactions and main effects.

Main Results:

  • Estimated trait score variance was significantly related to the Trait x Protocol interaction (omega 2 = .55).
  • The overall effect size indicated a multiple correlation of .74, suggesting acceptable meta-interpretive reliability for the KCR.
  • Individual differences among raters accounted for less than 1% of the score variance.

Conclusions:

  • The Karson Clinical Report demonstrates acceptable meta-interpretive reliability.
  • Meta-interpretive reliability serves as an index for the upper limit of CBTI validity.
  • Contextual effects from interpretive statements (protocol effect) influence score interpretation.
