Relationship between self-stigma about alcohol dependence and severity of alcohol drinking and craving.

Background: The correlates and consequences of stigma surrounding alcohol use are complex. Alcohol use disorder (AUD) is typically accompanied by self-stigma, due to numerous factors, such as shame, guilt and negative stereotypes. Few studies have empirically examined the possible association between self-stigma and alcohol-related outcomes.

Objective: To investigate the relationship between self-stigma about alcohol dependence and the severity of alcohol consumption and craving.

Methods: In a sample of 64 participants, the majority of whom had a diagnosis of AUD (51), bivariate correlations were first conducted between Self-Stigma and Alcohol Dependence Scale (SSAD-Apply subscale) scores and Alcohol Use Disorders Identification Test (AUDIT) scores, Alcohol Timeline Follow-Back, Obsessive-Compulsive Drinking Scale (OCDS) scores and Penn Alcohol Cravings Scale scores. Based on the results, regression analyses were conducted with SSAD scores as the predictor and AUDIT and OCDS scores as the outcomes.

Findings: SSAD scores positively correlated with AUDIT scores, average drinks per drinking day, number of heavy drinking days and OCDS scores (p<0.001, p=0.014, p=0.011 and p<0.001, respectively). SSAD scores were also found to be a significant predictor of AUDIT and OCDS scores (p<0.001 and p<0.001, respectively), even after controlling for demographics.

Conclusions: Higher levels of self-stigma were associated with more severe AUD, greater alcohol consumption, and more obsessive thoughts and compulsive behaviours related to alcohol.

Clinical Implications: Our results suggest that potential interventions to reduce self-stigma may lead to improved quality of life and treatment outcomes for individuals with AUD.
