The alcohol-adapted PDD appears to be a psychometrically and theoretically sound instrument for measuring PAS in samples of drinkers. A one-factor solution of the alcohol-adapted PDD offered a parsimonious approach to modeling PAS. To achieve optimal model fit, statistical adjustment for method effects introduced by reverse item wording was necessary. Future work should evaluate the measure’s sensitivity to change over time, and the extent to which results are impacted by self-report bias (e.g. neuroticism). Additional existing measures should be adapted to evaluate the stigma of AUDs, such as measures of stigma coping orientations.
