  Background Impulsive binge drinking is a serious public health issue, and to reveal predisposing factors to this consumption pattern is, therefore, required. Impulsivity-related traits are important predictors of alcohol use and abuse. Nonetheless, previous research in binge drinking has been confounded by various definitions and cut-off scores, implying that existing studies contributed to limited comprehension on the specific role of different impulsivity facets. The current study thus disentangles the role of impulsivity facets in binge drinking by adopting a dimensional approach, considering the condition on a continuum, to avoid relying on debatable and non-definitive criteria. Methods 162 students underwent assessment of alcohol consumption, including drinking patterns and impulsive traits, as captured in the UPPS-P framework (i.e., negative urgency, positive urgency, sensation seeking, lack of perseverance, lack of premeditation). Multiple regression analyses were utilized in order to investigate the predictive role of each impulsivity facet in binge drinking. Results Binge drinking was associated with sensation seeking. However, when statistically controlling for gender, age and global alcohol consumption, this effect disappeared, and negative urgency remained the only impulsivity component that significantly predicted binge drinking. Conclusion We found the severity of binge drinking to be associated with negative urgency, suggesting that the binge drinking pattern is displayed in reaction to negative emotional states, and can be conceptualized as a maladaptive and short-term emotional coping. The study calls for prevention and treatment interventions designed to improve self-control, and more adaptive emotion regulation strategies.

  Depression is a common illness which tends to have a relapsing progression. Revealing vulnerability factors is an important step towards improved treatment and prevention. Previous studies of individuals in remission indicate that inhibitory control is more strongly impaired than other cognitive functions. Studies have mostly used Stroop tasks; it is unclear how this population performs on other measures of inhibition. Abnormal reactions to errors may also promote depression relapse, but this has rarely been studied in remitted depression. We used a Stop Signal task and Stroop inhibition task to investigate inhibitory function and post-error reaction time adjustments in 54 individuals with a history of depression and 185 never-depressed controls. Inhibitory processing was slower among the remitted depressed individuals on the Stop Signal task, but no difference was found in Stroop inhibition. The groups were not different on post-error adjustments. This finding extends the understanding of inhibitory deficiency in this population and offers insight into trait markers of depression.
