Abstract

This retrospective study investigated the relationship between self-reports and caregiver perceptions of patients' depressive symptoms and the respective ability of these reports to predict instrumental activities of daily living (IADLs) beyond what is accounted for by cognitive abilities in 71 patients with mild Alzheimer disease. Patients completed the Geriatric Depression Scale-Short Form, and caregivers completed the Behavior Rating Scale for Dementia assessing their perception of patients' depressive symptoms. Caregivers also completed IADL items from the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory. Cognitive measures included the Mini-Mental State Examination, Logical Memory from the Wechsler Memory Scale III, and Trail Making Test, Part B. The relationship between self-reported depressive symptoms and caregiver report of patients' depressive symptoms showed a trend toward significance (r = .22, P = .06). Measures of depressive symptoms significantly predicted 12.5% of the variance in IADLs performance, beyond that accounted for by patient demographics and cognitive functioning. Interestingly, patients' reports, rather than caregivers', were particularly useful in this prediction.
