Rash-impulsivity, reward-drive and motivations to use ecstasy

An increase in the recreational use of ecstasy has prompted much research focusing on the effects of repeated use. Less is known about the individual predictors of ecstasy use although a number of studies have pointed to impulsive personality traits. The current study examines this issue by drawing on a recently developed dual-factor model of impulsivity (rash-impulsivity/reward-drive; Dawe & Loxton, 2004). Two-hundred and seven participants completed questionnaires assessing rash-impulsivity, reward sensitivity, affect and motivations for use. Ecstasy users were significantly higher on rash-impulsivity and reward sensitivity compared to non-users. Furthermore, negative affect mediated the relationship between rash-impulsivity and negative reinforcement motivations. Discussion focuses on the role of rash-impulsivity and reward-drive in understanding the motivational processes underlying ecstasy use.
