Background: Alcohol 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 current alcohol use among individuals with severe AUD who ever attended Alcoholics Anonymous (AA), a widespread and easily accessible self-help group for alcohol problems.
Methods: Univariable 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.
Results: Results from the multivariable model indicated that in females who attended AA, higher alcohol use was related to both positive and negative urgency as well as low sensation seeking, while in males, higher alcohol use was related to positive urgency. Results also indicated an important role of younger age and lower educational levels in higher alcohol use in both sexes. Moreover, single males and those with lower AUD severity were at higher risk of using alcohol in the past year.
Conclusions: These findings highlighted sex-specific correlates of drinking in individuals with AUD who engaged in self-help groups. Findings may be useful to improve treatment options, as personality encompasses modifiable traits that can be targeted in psychological interventions.
