Self-stigma in alcohol dependence scale: development and validity of the short form.

Background: Self-stigma is associated with low self-esteem, high shame and reduced drinking-refusal self-efficacy in people with alcohol use disorder (AUD). The Self-Stigma in Alcohol-Dependence Scale-Short Form (SSAD-SF) was designed to enable a brief, but valid assessment of AUD self-stigma.

Methods: We reduced the 64-item SSAD, originally derived from 16 stereotypes towards people with AUD, by removing the most offensive items based on perspectives of people with lived experience. The newly created scale was then assessed and validated in a cross-sectional study involving 156 people reporting alcohol issues in various treatment settings.

Results: The 20-item SSAD-SF includes five stereotypes, with good internal consistency for each subscale and the overall scale. It reflects the four-stage progressive model of self-stigmatization with decreasing scores over the stages awareness of stereotypes, agreement with stereotypes, self-application of stereotypes, and harmful consequences for self-esteem, and highest correlations between adjacent stages. The subscales apply and harm were associated with internalized stigma, shame, reduced self-esteem, and lower drinking-refusal self-efficacy, as supported by multivariate regression models.

Discussion: The SSAD-SF is a valid instrument for measuring the process of self-stigmatization in people with AUD. Self-stigma is a consistent predictor of reduced self-esteem, higher shame and lower drinking-refusal self-efficacy in people with AUD. We discuss merits of the progressive model for understanding and addressing self-stigma in AUD.
