Wisconsin Card Sorting Test-Learning Potential: Usefulness for Assessing Children with Autism Spectrum Disorder

Area of Science:

• Neuroscience
• Developmental Psychology
• Clinical Psychology

Background:

• Autism Spectrum Disorder (ASD) presents challenges in cognitive and social functioning.
• The Wisconsin Card Sorting Test-Learning Potential (WCST-LP) is a tool for assessing cognitive flexibility and learning.
• Understanding the utility of WCST-LP in ASD populations is crucial for accurate assessment and prognosis.

Purpose of the Study:

• To evaluate the construct validity of the WCST-LP in children with ASD.
• To examine the influence of Full-Scale IQ on WCST-LP pretest and learning potential (LP) scores.
• To investigate the relationship between WCST-LP performance and cognitive/executive functions (EF) and social abilities in children with ASD.

Main Methods:

• A cohort of 105 children, including 43 with ASD and 62 with typical development (TD), participated in the study.
• The WCST-LP was administered to assess cognitive flexibility and learning potential.
• Statistical analyses were performed to evaluate construct validity, IQ effects, and correlations with cognitive and social measures.

Main Results:

• Evidence for construct validity of the WCST-LP was found in the ASD group, indicated by significant improvements from pretest to posttest.
• Full-Scale IQ significantly impacted pretest performance but did not influence LP scores.
• A significant relationship between WCST-LP and verbal and social abilities was observed exclusively in children with ASD.

Conclusions:

• The WCST-LP demonstrates construct validity and clinical utility in assessing children with ASD.
• WCST-LP performance, particularly LP, shows specific associations with cognitive and social skills in ASD.
• The findings support the appropriateness of the WCST-LP as a tool for aiding in the prognosis assessment of Autism Spectrum Disorder.
