Summary

A written supplement significantly improved scoring accuracy for the Wisconsin Card Sorting Test (WCST), especially for perseverative responses. This guide made novice raters as reliable as experts in WCST scoring.

Area of Science:

  • Neuropsychology
  • Cognitive Assessment

Background:

  • The Wisconsin Card Sorting Test (WCST) is a key neuropsychological tool.
  • Accurate administration and scoring are crucial for WCST utility.
  • Perseverative responses are challenging to score accurately.

Purpose of the Study:

  • To evaluate the reliability and accuracy of different WCST scoring guides.
  • To identify the most effective instructional set for novice WCST users.
  • To improve the scoring of perseverative responses.

Main Methods:

  • Novice raters used four scoring methods: original manual, decision tree with manual, written supplement with manual, and revised manual.
  • Expert raters also scored protocols.
  • All groups scored 20 difficult WCST protocols, focusing on perseverative responses.

Main Results:

  • Novice raters using the written supplement achieved expert-level accuracy and reliability in scoring perseverative responses.
  • The revised manual improved scoring over the original manual but was less effective than the supplement.
  • The original manual alone and the decision tree guide showed lower reliability.

Conclusions:

  • Empirical validation of scoring accuracy for cognitive measures is essential.
  • A written supplement enhances WCST scoring reliability for novice users.
  • Standardized training and validated guides are recommended for cognitive tests.
