Rash impulsiveness and reward sensitivity as predictors of treatment outcome in male substance dependent patients.
Recent theories hypothesize that the impulsivity observed in addictive behaviors is a two-factor construct, consisting of Rash Impulsiveness and Reward Sensitivity. There is some evidence for this distinction, but it is unknown what the clinical relevance of this distinction is. The present study examines the predictive value of the two-factor model regarding drop-out from treatment and relapse into substance use in a clinical population of male substance dependent patients. Both behavioral and self-report measures of Rash Impulsiveness and Reward Sensitivity were measured during treatment while substance use relapse was measured after 90days. Results indicate that treatment drop-out could be predicted by a behavioral index of Reward Sensitivity (Card Playing Task); self-reported Rash Impulsiveness only approached significance as predictor drop-out. In contrast, relapse could not be predicted in the present study. These findings might have implications for the early identification and treatment of patients at risk of treatment drop-out.
