Objective: Determine whether adults with hepatitis C (HCV), regardless of substance use disorder, are more likely to discount delayed rewards than adults without hepatitis C, and explore the relationship between delay discounting and neuropsychological functioning.
Methods: Procedures included clinical interviews, neuropsychological testing, and a delay discounting task.
Results: Regardless of substance abuse history, adults with hepatitis C were significantly more likely to choose smaller immediate rewards over larger delayed rewards. Delay discounting correlated with performance on executive functioning tasks.
Conclusions: Increased discounting is associated with broad executive dysfunction, suggesting that HCV-associated executive dysfunction may lead to altered decision-making style.
