The concepts of Rash Impulsiveness and Reward Sensitivity in substance use disorders.
European Addiction Research , Volume 19 p. 261- 268
According to recent theories of addiction, the commonly used term impulsivity comprises two factors: rash impulsiveness and reward sensitivity. The present study addresses the relevance and generalizability of this two-factor model in a clinical sample of substance use disorder patients. This was examined by examining both internal and external validity. In addition, a comparison was made between self-reported and behavioral measures reflecting reward sensitivity and rash impulsiveness. Results provide evidence for the existence of the two hypothesized impulsivity factors in a clinical sample of substance dependent patients. Meaningful relationships between the model and drug use characteristics have been found, providing further evidence for the validity of the two-factor model. Furthermore, it is suggested that behavioral and self-report measures of impulsivity represent different constructs.
