abstract = {Background: The treatment of cocaine-dependent individuals (CDI) is substantially challenged
by high drop-out rates, raising questions regarding contributing factors. Recently,
a number of studies have highlighted the potential of greater focus on the clinical significance
of neurocognitive impairments in treatment-seeking cocaine users. In the present
study, we hypothesized that disadvantageous decision-making would be one such factor
placing CDI at greater risk for treatment drop-out.
Methods: In order to explore this hypothesis, the present study contrasted baseline performance
(at treatment onset) on two validated tasks of decision-making, the Iowa Gambling
Task (IGT) and the Cambridge GambleTask (CGT) in CDI who completed treatment in a residentialTherapeutic
Community (TC) (N=66) and those who dropped out ofTC prematurely
(N=84).
Results: Compared to treatment completers, CDI who dropped out ofTC prematurely did
not establish a consistent and advantageous response pattern as the IGT progressed and
exhibited a poorer ability to choose the most likely outcome on the CGT. There were no
group differences in betting behavior.
Conclusion: Our findings suggest that neurocognitive rehabilitation of disadvantageous
decision-making may have clinical benefits in CDI admitted to long-term residential
treatment programs.},
