TL;DR
It is concluded that interpretation of the WCST results of patients with TBI should consider the multifactorial nature of the instrument in combination with injury severity characteristics and demographic variables.
Abstract
The performance of 100 patients with traumatic brain injury (TBI) on the Wisconsin Card Sorting Test (WCST) was examined to determine the underlying latent structure as well as profile subtypes. Exploratory factor analysis with oblique rotation identified three factors: response accuracy, learning, and failure to maintain set. Marker variables from each factor were then included in a two-stage cluster analysis, which identified two reliable subtypes. Level of performance differences between these subtypes were meaningfully related to both demographic background and length of coma. It is concluded that interpretation of the WCST results of patients with TBI should consider the multifactorial nature of the instrument in combination with injury severity characteristics and demographic variables.

A clinical scale has been evolved for assessing the depth and duration of impaired consciousness and coma that facilitates consultations between general and special units in cases of recent brain damage, and is useful also in defining the duration of prolonged coma.

Analysis of WCST performances associated with damage to various subregions of the frontal lobes also failed to reveal any reliable relationships, indicating that performance on the WCST cannot be interpreted in isolation as an index of frontal lobe damage.

Two patterns of performance characterized the three patient groups: the schizophrenic group and frontal lobe group had the highest Perseveration factor scores, whereas the alcoholic groupHad the highest Inefficient Sorting scores; the Nonperseverative Errors factor showed no significant group differences.
Clinical NeuropsychologistWisconsin card sorting test as a measure of frontal pathology: A review
188 Citations1993Mary Mountain, William G. Snow
It is indicated that few studies had investigated the differential performance of normals and those with frontal dysfunction, and there is insubstantial evidence to conclude that the WCST is a measure of dorsolateral-frontal dysfunction.

The results suggest that tests that are traditionally used to detect "frontal lobe" damage may not be adequate for distinguishing specific frontal lobe dysfunction, and do not add anything unique about frontal lobe integrity and neuropsychological functioning in TBI patients.

The CT and WCST should not be regarded as similar measures of one construct such as "abstraction," but use of discrete scores from each test can help assess different aspects of concept formation.

Adequate construct validity was found for "conceptualization/problem solving" and "failure to maintain set" factors in both groups and this suggests that the WCST provides information about problem solving relatively independent of memory and attention functions for elderly persons.

CVLT data from 88 acute rehabilitation inpatients with mild, moderate, and severe traumatic brain injuries was analyzed with multiple cluster analytic techniques and yielded five learning subtypes, three of which appeared similar to the subtypes previously identified as Active, Disorganized, and Passive subtypes.

The findings revealed that in normal individuals, the WCST is best described by a unitary factor, and in neurological patients with either focal or diffuse impairment, performance on this test is primarily explained on the basis of two factors: Problem Solving/Perseveration and Loss of Set.

16 Citations1997Ann B. Shuttleworth-Jordan
An argument is presented which suggests that the relative absence of positive findings in the Reitan and Wolfson research is inconsistent with current theoretical and research indications of a high probability for compromised neuropsychological function in brain-damaged populations due to older age and lower education effects.

The results indicate that TBI interferes with performance on tests requiring individuals to process information into new categories, and there appears to be a dissociation between verbal abstract abilities and visual-perceptual abstract abilities.
