Young adults who made riskier decisions showed more severe binge drinking later. Executive functions, like working memory and response inhibition, did not predict changes in binge drinking severity over time.

Area of Science:

  • Neuroscience
  • Psychology
  • Addiction Research

Background:

  • Executive functions (EFs) are linked to binge drinking in young adults.
  • Limited research exists on how EFs predict future binge drinking patterns.

Purpose of the Study:

  • To examine the association between various EFs and the severity of, and changes in, binge drinking.
  • To investigate binge drinking over an extended period in young adulthood.

Main Methods:

  • 121 students assessed baseline alcohol habits and executive functions (working memory, decision-making, etc.).
  • Alcohol habits were reassessed after 18 months for 103 participants.
  • Multilevel regression modeling analyzed the data.

  • Risky decision-making, assessed via the Information sampling task, uniquely predicted future binge drinking severity (β = -1.86).
  • No study variables predicted the change in binge drinking severity.
  • Performance on other executive function tasks was unrelated to binge drinking severity or change.

Conclusions:

  • Making risky decisions, particularly for potential gain, is associated with future binge drinking severity, suggesting reward hypersensitivity.
  • Further research is needed to establish a causal link between decision-making and binge drinking.
  • The lack of association with changes in binge drinking may be due to short follow-up and small observed changes.
