Wisconsin Card Sorting Test (WCST). Adaptación y datos normativos de la versión de 64 cartas

Introduction

The Wisconsin Card Sorting Test (hereinafter WCST) was created to evaluate the capacity of abstraction, the formation of concepts and the change of cognitive strategies in response to the changes that occur in environmental contingencies. It is a proof of use par excellence in the neuropsychological clinic, however, so far, the version of 64 cards did not have beams for use in Argentina.

Objectives

The objective of this study was to establish the normative values of the WCST, in the version of 64 cards, and to establish correction criteria less complex and consistent with the use given by professionals in the clinical field.

Participants

People between 20 and 60 years of age belonging to a population of people residing in the Province of Córdoba were evaluated.

Methods

An agreement was made between judges to establish the correction variables according to their frequency of use. A multiple regression was carried out in order to analyze differences between age, educational level and gender.

Results

Differences in the variable educational level were observed. The correction variables were established.

Conclusions

Studies previously conducted with WCST show that people with frontal injury complete a smaller number of categories and make more persistent errors, however the test cannot predict the origin of the injury and is not specific to frontal lesions, since people with subsequent injuries also decrease performance in both variables. People with psychiatric disorders may also experience an increased number of persistent errors.
