Abstract

The aim of this study was to examine the association between baseline executive functioning and outcome measure of treatment in 226 cocaine dependent individuals who initiated treatment in therapeutic communities TCs. The study was conducted across six TCs located in the region of Andalusia (southern Spain). Neuropsychological testing included tests of working memory, reasoning, inhibition, switching, attention interference and decision making. The outcome measures were type of discharge (treatment dropout vs. therapeutic discharge) and clinical impression of the TC outcome (clinically significant vs. non-significant changes). In the present study a prospective comparative design was used. We found significant performance differences on selective executive components which account for the type of discharge: treatment quitters had poorer attention response inhibition and attention switching than non-quitters, and the individuals who failed to achieve therapeutic objectives had poorer attention interference and inhibitory control than compliers. No significant differences were found between the outcome measure and the neuropsychological performance score on the other tasks. The results provide important information about the impact of executive components on in-treatment follow-up outcomes among dependence disorders in TC.
