For the informant-reported SCD and cognitive measures, values indicate the results of the simple linear regressions (r and p values) between the self-reported global_R SCD score on the one hand and the corresponding variables on the other hand. For the psychoaffective measures, values indicate the results of the general linear model between the self-reported global_R SCD score and these measures, correcting for age and education. Values indicated in italics correspond to p < 0.05
