“…To evaluate the following hypotheses, a well-validated vignette approach (Perry et al, 2020) was used to activate perceptions of SUD (i.e., attributions, social distance; see Krendl & Perry, 2022, for details on specific vignettes). By encouraging respondents to think about a specific person, vignettes may activate latent stigmatizing beliefs more effectively than traditional survey instrument, thus becoming a relatively standard way for studying these constructs (e.g., Kelly et al, 2021; Krendl & Perry, 2022; Pennington et al, 2023; Perry et al, 2020; Ragsdale & Elliott, 2022; Röhm et al, 2022; Rundle et al, 2021). Guided by a mixture of attribution theory (Link & Phelan, 2001; see also Weiner, 1980), genetic essentialism (e.g., Harden, 2023), and existing evidence (i.e., Jacobi et al, 2022; Ragsdale & Elliott, 2022; Röhm et al, 2022; Yang et al, 2017), bad character attributions were postulated to be the main drivers of substance use stigma (i.e., social distance), even when controlling for biological attributions (Hypothesis 1a).…”
