Brain-derived neurotrophic factor Val66Met polymorphism moderates the relationship between impulsivity, negative emotions, and binge drinking intensity in university students.

Studies on the genetic factors involved in binge drinking (BD) and its associated traits are very rare. The aim of this cross-sectional study was to investigate differences in the association between impulsivity, emotion regulation and BD in a sample of young adults according to the rs6265/Val66Met variant in the brain-derived neurotrophic factor (BDNF) gene, a well-known candidate gene in alcohol use disorders. We recruited 226 university students (112 women), aged between 18 and 25 years old, from two centers in France.

Disentangling the Relationship Between Self-Esteem and Problematic Alcohol Use Among College Students: Evidence From a Cluster Analytic Approach.

Aims: Investigation of the relationship between self-esteem and alcohol use among college students has yielded discrepant results. We hypothesized that these discrepancies could originate from a potential heterogeneity of self-esteem patterns among young adult with an alcohol use disorder (AUD).

Methods: A community sample of 343 college students was recruited and categorized with or without AUD using the Alcohol Use Disorders Identification Test cut-offs.

Cloninger's Temperament and Character Dimensions of Personality and Binge Drinking Among College Students.

Background: Temperament and character dimensions of personality remain largely unexplored in young adults exhibiting binge drinking (BD) patterns. Moreover, the available studies do not consider gender differences and dismiss possible personality heterogeneity among binge drinkers. In this study, we aimed to compare temperament and character dimensions between young binge drinkers and age- and sex-matched social drinkers.

Relations Between Cognitive Abilities, Drinking Characteristics, and Emotional Recognition in Alcohol Dependence: A Preliminary Exploration.

Background: Alcohol dependence is characterized by wide-ranging cognitive impairments, but also by emotional facial expressions (EFEs) recognition deficits. Although they play a crucial role both in the development and in the maintenance of the disease, cognitive and emotional disorders have up to now been mostly explored separately. As a result, not much is known regarding their interactions.
