title: Short-term prospective effects of impulsivity on binge drinking: mediation by positive and negative drinking consequences.
abstract: OBJECTIVE
  Although the association of impulsivity with diverse alcohol outcomes has been documented, the mechanisms by which impulsivity predicts drinking over time remain to be fully characterized. The authors examined whether positive drinking consequences, but not negative drinking consequences, mediated the association between impulsivity and subsequent binge drinking, over and above prior binge drinking.
  
  
  METHODS
  Participants were 171 college students.
  
  
  METHODS
  Participants completed 2 online surveys with an average interval of 68 days between assessments at Time 1 (September to October 2012) and Time 2 (November to December 2012).
  
  
  RESULTS
  Path analysis showed that, among 5 facets of impulsivity, the effect of sensation seeking on subsequent binge drinking was completely mediated by prior positive consequences. No mediating effects of negative consequences were found.
  
  
  CONCLUSIONS
  Prior experience of positive drinking consequences may serve as one of the risk pathways by which sensation seeking shapes binge drinking over time. Personalized intervention strategies may utilize information about students' impulsivity facets to address their binge drinking and alcohol-related consequences.
