“…The assessment covers a broad range of cognitive abilities including memory, language abilities, and executive functioning. Because previous clinical research showed that cognitive abilities can be adequately described with an overarching g factor (Benson et al, 2018;McGill & Dombrowski, 2019), we aggregated all (standardized) sum scores into a single score. To assess the severity of depressive symptoms in both groups, the scores of two self-report measures (Beck's Depression Inventory, BDI, Hautzinger et al, 1995, and the Geriatric Depression Scale, GDS, Gauggel & Birkner, 1999) and a clinical rating (Montgomery-Åsberg Depression Rating Scale, MADRS, Schmidtke et al, 1988) were combined.…”
