Use of Wisconsin Card Sorting Test short forms with school-age children

Area of Science:

• Neuropsychology
• Child Psychology
• Cognitive Assessment

Background:

• The Wisconsin Card Sorting Test (WCST) is a key measure of executive function.
• Short forms of the WCST exist for adults, but their validity in children is understudied.
• Neuropsychological evaluations for children often require reliable cognitive assessments.

Purpose of the Study:

• To compare the validity of two short forms of the WCST against the full WCST in school-aged children.
• To determine if short forms of the WCST provide equivalent results to the full version in a pediatric population.
• To offer guidance on the appropriate use of WCST short forms in child neuropsychology.

Main Methods:

• A sample of 174 school-age children underwent assessment using the full WCST and two short forms.
• Standard scores (SSs) for the full WCST were predicted using multiple regression.
• Percent scores from short forms were converted to SSs using existing WCST manual normative data.

Main Results:

• Scores from WCST short forms showed significant correlations with the full WCST.
• A substantial number of children achieved short form SSs that significantly differed from their full WCST SSs.
• The discrepancies suggest potential unreliability of short forms in this pediatric sample.

Conclusions:

• The full Wisconsin Card Sorting Test is recommended for pediatric neuropsychological evaluations.
• Short forms of the WCST may not be interchangeable with the full version in children.
• Clinicians should exercise caution and consider using the full WCST unless at least four categories are achieved on the first deck with a short form.
