Objectives. The Cognitive Performance Test (CPT) is a functional assessment for persons with dementia. The study purpose was to evaluate the reliability, discriminant, and concurrent validity of the CPT. Method. The CPT was tested against other measures of cognition (Standardized Mini Mental Status Exam (SMMSE) and Assessment of Motor and Process Skills-Process scale (AMPS-Process)). Participants were persons 65 years and older admitted to a geriatric rehabilitation unit ( ). Results. The CPT correlated moderately with measures of cognition (SMMSE , AMPS-Process , ), and ADL burden of care (FIM , ). Scores were not affected by age, sex, years of education, motor skills, or comorbidities. The CPT differentiated between impaired and unimpaired individuals differently from other measures. Conclusion. While CPT appears related to other measures of cognition, test interpretation requires noting the variability between CPT scores and those measures. 1. Introduction Cognitive impairment is one of the strongest predictors of institutionalization, increasing the risk by two and a half times [1]. There is likely to be an increase in institutionalization with the aging population and an associated individual and societal burden. Evidence-based care is a priority with this patient population for caregivers, families, individuals, and policy makers. Cognitive impairment may be associated with various pathologies including Alzheimer’s disease, vascular dementia, mixed dementias, or cognitive decline secondary to Parkinson’s disease. The role of occupational therapy is to enable the performance of everyday activities and participation [2, 3]. For persons with cognitive deficits, there is impairment in the ability to perform some activities of daily living (ADL) (essential self-care tasks, for example, bathing, dressing, grooming) and instrumental activities of daily living (IADLs) (a secondary set of tasks required for independent living, for example, cooking, shopping) [4]. Occupational therapists who see people with cognitive deficits in hospitals are concerned with their ability to live independently and safely after discharge and to recommend the amount of assistance required [5, 6]. Occupational therapists need to use an evidence-based evaluation of the ability of persons with cognitive deficits to complete functional tasks. The Cognitive Performance Test (CPT) was developed for the assessment of older adults with cognitive deficits [7]. It is designed to structure observations of the performance of persons on specific ADL and IADL tasks. The test is designed for
