While the hypothesized two-factor model had the best fit to the data, the extremely high inter-factor correlation (r=0.9) suggested that the perceived devaluation and perceived discrimination factors had low discriminant validity (Brown 2006). Our selection of a one-factor model is consistent with the most common use of the original and adapted scales (“perceived devaluation-discrimination”) (Keyes et al. 2010; Link et al. 1989; Luoma et al. 2010). While “positive” and “negative dimensions” of perceived stigma have been proposed (Interian et al. 2010), our models did not support that structure.
