Personality correlates of past‐year alcohol use in individuals with severe alcohol use disorder and a lifetime history of involvement in alcoholics anonymous

Abstract

BackgroundAlcohol use disorder (AUD) is a highly impairing condition with important public health impacts. Despite the availability of treatment options for AUD, research shows that few people receive treatment, and even fewer can maintain abstinence/low‐drinking levels. This study investigated the role of personality traits in past‐year alcohol use among individuals with severe AUD who ever attended Alcoholics Anonymous (AA), a widespread and easily accessible self‐help group for alcohol problems.MethodsUnivariable and multivariable regressions were performed separately in females and males with alcohol consumption as an outcome. Socioeconomic factors, genetic liability, and psychopathology were included as covariates in the analyses.ResultsResults from the multivariable model indicated that in females who attended AA, greater alcohol use was related to both positive and negative urgency and low sensation seeking, while in males, greater alcohol use was related to positive urgency. Results also showed that, in both sexes, younger age and lower educational levels were associated with greater alcohol use. Moreover, single males and individuals with lower AUD severity were at higher risk of using alcohol in the past year.ConclusionsThese findings highlight sex‐specific correlates of drinking in individuals with AUD who engaged in self‐help groups. These findings may help to improve treatment options, as personality encompasses modifiable traits that can be targeted in psychological interventions.
