Binge Drinking Trajectory and Decision-Making during Late Adolescence: Gender and Developmental Differences

Area of Science:

• Neuroscience
• Psychology
• Addiction Research

Background:

• Alcohol dependence is linked to impaired decision-making.
• Adolescent binge drinking (BD) and its impact on decision-making require further investigation.
• Understanding developmental changes in decision-making across genders is crucial.

Purpose of the Study:

• To examine the longitudinal association between binge drinking and decision-making from late adolescence to early adulthood.
• To assess developmental changes in decision-making performance.
• To identify gender-based differences in decision-making related to binge drinking.

Main Methods:

• A 4-year prospective study of 155 university students (non-BDs and BDs).
• Classification of participants into stable non-BDs, stable BDs, and ex-BDs.
• Assessment of decision-making using the Iowa Gambling Task (IGT) and analysis via generalized linear mixed models.

Main Results:

• Stable binge drinking was not associated with disadvantageous decision-making or loss frequency sensitivity.
• Decision-making performance improved significantly in both genders over time.
• Females exhibited higher sensitivity to loss frequency compared to males.

Conclusions:

• Affective decision-making skills continue to develop through late adolescence and early adulthood.
• Neuromaturational development supports improved decision-making in both genders.
• Stable binge drinking in this age group does not appear to cause decision-making deficits.
