AbstractObjectivesMedical treatment non‐adherence among older adults is common and represents a significant public health care concern. Treatment non‐adherence has been associated with a number of factors in older adults; however few studies have delineated the role of cognition and psychiatric status.ParticipantsData were collected from 212 ethnically diverse older primary care patients as part of a larger study.MeasurementsCognitive status was evaluated with the Mattis Dementia Rating scale (DRS). Psychiatric status was evaluated using the Geriatric Depression Scale (GDS) and the Beck Anxiety Inventory (BAI). Treatment adherence was assessed by the total number of missed healthcare appointments and by physician and patient ratings. Physician ratings of patients' understanding of medical instructions were also obtained.DesignA series of multiple regression analyses were conducted to determine cognitive and psychiatric predictors for each measure of treatment adherence.ResultsGDS and DRS memory scores were both independent predictors of the total number of missed medical appointments, F(7,55) = 2.34, p = 0.038. GDS score was also shown to be a significant predictor of physician ratings of patients' understanding of medical instructions, F(7,33) = 0.89, p = 0.031. Neither cognitive performance nor psychiatric status was associated with patient or physician ratings of treatment adherence.ConclusionsMeasures of cognitive functioning and depression severity were supported as predictors of objective measures of treatment adherence but they were not associated with physician or patient ratings of adherence. Patient depression may influence physician ratings of patients' comprehension of medical instructions. Copyright © 2006 John Wiley & Sons, Ltd.
