| Abstract/Results: | ABSTRACT:
The Halstead Category Test (HCT) is a neuropsychological measure that taps into multiple domains of complex non-verbal reasoning and cognitive flexibility, but only yields a single error score, limiting the clinical use of the test. Currently, several authors have proposed additional subscales in order to increase the clinical utility of the HCT. The purpose of this study is to present the new scales and scoring criteria of HCT, as well as to analyze the construct validity of the new scales recently developed to assess specifics domains of executive function: cognitive flexibility, failure to maintain cognitive set, perseveration and memory. Using a sample of Portuguese undergraduate students aged 19-50 years, we will relate the values obtained in the new scales of the HCT with well-established neuropsychological measures (Trail making A and B, Test of Non-Verbal Intelligence, California Learning Verbal Test and Symbol Digit). After data analysis, and based in previous results, we hope to find that the new scales of HCT (perseveration, set of loss, categorization and memory), show clearly a significant associations with the neuropsychological measures used in this study. These results will be compared with international data, with the important starting point for the clinical use of the new scales.
