Abstract
BACKGROUND: Binge Drinking (BD) generally declines once students have left university. However, many individuals continue to partake in BD into adulthood, constituting a scarcely investigated high-risk group towards whom interventions should be prioritized. Following the dual-process model, we examined the relationship between BD and both the reflective system (executive functions) and the affective system (alcohol bias) in young adults with a consistent BD trajectory. We considered impulsivity as a moderator in the relationship between BD and alcohol bias. METHODS: A cohort of 63 (31♀) young adults were followed for eleven years (18-29 years old). In the last assessment, participants, with high and low drinking trajectories underwent neuropsychological assessment of executive functions (working memory [SOPT], cognitive flexibility [TMT -Verbal Fluency], inhibition [Stroop]) and alcohol bias (Addiction Stroop). The Barratt Impulsivity Scale measured impulsivity. Generalized linear mixed models and regression-based moderation models were applied. RESULTS: BD was associated with weak inhibitory control, poor working memory and greater alcohol bias moderated by non-planning impulsivity. At moderate levels of non-planning impulsivity, BD was associated with greater alcohol bias. This association was not found at high levels of impulsivity. These deficits were related to loss of control over drinking and severity of alcohol use. CONCLUSIONS: The imbalance between poor cognitive control and greater alcohol bias may contribute to the persistence of BD into adulthood. The findings highlight the complexities of the dual-process model, with intervention implications.
