RESUMO
Este estudo investigou como ocorre o processo de tomada de decisão em dependentes de crack pelo instrumento Iowa Gambling Task (IGT). Foram selecionados 30 participantes para o grupo de dependentes de crack - GDC, e 15 controles não usuários - GNU, de ambos os sexos. Para avaliar a intensidade de craving utilizou-se o Cocaine Craving Questionnaire-Brief. Houve diferenças significativas entre os grupos tanto no cálculo total, como no cálculo por blocos. A curva de aprendizagem do GDCmanteve-se constante e negativa na maior parte do jogo, havendo apenas no final um indício de aprendizagem. Em relação à classificação do desempenho na tarefa, as análises evidenciaram que um significativo número de participantes controles obtiveram desempenho não-prejudicado, oposto ao desempenho do GDC. As diferenças entre os grupos investigadas no IGT corroboraram com achado de estudo anterior, que evidenciou prejuízo no processo de tomada de decisão associado à dependência de cocaína e de crack.
ABSTRACT
This study investigated how decision-making process occurs in crack dependents through the Iowa Gambling Task (IGT). 30 participants were selected to crack dependent group - GDC, and 15 non-users controls - GNU, from both sexes. We used the Cocaine Craving Questionnaire-Brief to assess the craving intensity. There were significant differences between groups both in the total-calculus score and in the blocks scores. The learning curve of the GDC was constant and negative during almost all game, except in the very ending when a suggestion of learning was observed. Regarding the task performance's classification, the analysis showed that a significant number of controls participants achieved a non-impaired performance, opposed to GDC performance. The differences between groups investigated in the IGT corroborate with a previous study finding, about a worse decision-making process associated with cocaine and crack addiction.
