Several adaptations of the PDD for AUD/SUD, including the one examined in this paper, have been found to have strong psychometric properties, including good internal consistency (α=0.82), excellent test-retest reliability (ICC=0.93), and satisfactory content and face validity (Ruan et al. 2008; Luoma et al. 2010). As well, PAS scores have been correlated with lower mental health functioning scores and a decreased likelihood of alcohol treatment (Keyes et al. 2010; Smith et al. 2010).
