Assessment, Ahead of Print.
This study examined the utility of dichotomous versus dimensional scores across two measures of social determinants of health (SDOH) regarding their associations with cognitive performance and psychiatric symptoms in a mixed clinical sample of 215 adults referred for neuropsychological evaluation (Mage = 43.91, 53.5% male, 44.2% non-Hispanic White). Both dimensional and dichotomous health literacy scores accounted for substantial variance in all cognitive outcomes assessed, whereas dimensional and dichotomous adverse childhood experience scores were significantly associated with psychiatric symptoms. Tests of differences between correlated correlations indicated that correlations with cognitive and psychiatric outcomes were not significantly different across dimensional versus dichotomous scores, suggesting that these operationalizations of SDOH roughly equivalently characterize risk of poorer cognitive performance and increased psychiatric symptoms. Results highlight the necessity of measuring multiple SDOH, as different SDOH appear to be differentially associated with cognitive performance versus psychiatric symptoms. Furthermore, results suggest that clinicians can use cut-scores when characterizing patients’ risk of poor cognitive or psychiatric outcomes based on SDOH.
