This study assessed the degree to which anxiety and depression symptoms are associated with memory and executive functioning among community-dwelling older adults (N = 120; M age = 74.9 years, SD = 7.2 years; 62% Women). Participants completed the Geriatric Anxiety Scale, Geriatric Depression Scale, Comorbidity Index, California Verbal Learning Test, Second Edition (CVLT-II), and the Trail Making, Verbal Fluency, and 20 Questions subtests of the Delis-Kaplan Executive Function System (D-KEFS): Multiple regression analyses indicated that anxiety and depression predicted poorer ability to learn new information (CVLT-II, Trials 1-5). Both anxiety and depression predicted performance on the D-KEFS Trail Making test, Number-Letter Switching condition. Anxiety, but not depression, predicted decreased categorization as measured by the D-KEFS 20 Questions, Initial Abstraction Score. Depression but not anxiety, predicted performance on D-KEFS Letter Fluency and Category Fluency. Findings suggest that anxiety and depression have unique relationships with cognitive functioning in community-dwelling older adults. (c) 2012 Elsevier Ltd. All rights reserved.
