Estudo de fidedignidade do instrumento neuropsicológico Iowa Gambling Task

OBJECTIVE: This study aimed at evaluating reliability evidence of neuropsychological instrument Iowa Gambling Task (IGT) by the means of the test-retest method. METHOD: The sample was comprised of 50 healthy subjects, 19-75 years of age, with at least five years of formal education. The assessment was done individually, in two meetings with an interval from 1 to 6 months between test and retest. RESULTS: The findings showed a significant moderate positive correlation between test-retest in the overall calculation. In the analysis by segments, a significant moderate positive correlation was found for blocks 4 and 5, whereas there were no significant correlations for blocks 1, 2 and 3. CONCLUSION: These data corroborate recent studies that found moderate correlations between test-retest measures of executive functions, and suggest that the IGT can be used to assess decision making over time if specific analyses are taken into account.

A tomada de decisão em adultos jovens e em adultos idosos: um estudo comparativo

The present study compared young and elderly adults as to their performance in the IGT. The sample was comprised of 72 individuals, distributed into two age groups: 36 young adults (M = 29.86, SD = 4.63) and 36 older adults (M = 66.89, SD = 5.19). considering the calculation-based score (mental), there was no difference between the groups as the choice of the cards (p = 0.60). However, there was significant difference as to the learning processes (p = 0.026). There was no significant difference when considering the score based on frequency (punishment), neither as to the choice of cards (p = 0.48), nor as to the learning process (p = 0.076). The results corroborate previous studies, which do not consider age as a factor that influences IGT performance. The scores analysis might have a strong influence on the understanding of the choice behavior, in addition to aspects relative to sample composition.
