The Influences of Impulsivity and Education Levels on Severity of Alcohol Dependence.

Background Impulsivity contributes to the severity of alcohol use disorder. The association is affected by expectation towards alcohol use, emotional regulation and self-control. Here we investigated the influences of self-reported impulsivity and levels of education on severity of alcohol dependence. Method We retrospectively analyzed the basic demographic information, alcohol consumption state, education years, depression and anxiety state, Alcohol Use Disorder Identification Test (AUDIT) and Barrett Impulsivity Scales (BIS) from a group of 66 AUD patients. Result Impulsivity significantly predicted alcohol dependence severity (R-2= 0.069,F= 4.724,p= 0.034). In addition, education years served as a moderator in the relationship between impulsivity and alcohol dependence severity (Delta R-2= 0.059, F = 4.414,p= 0.040). Conclusion Self-reported impulsivity affects the severity of alcohol dependence, which might be different in patients with different education levels.
