The Cognitive Performance Test (CPT) is a standardized, performance-based assessment instrument, originally designed for the objective evaluation of function in Alzheimer’s Disease. The CPT is available for purchase through Maddack at: maddak.com . This instrument, based on Allen Cognitive Disability Theory, uses six common activities of daily living (ADL) tasks, for which the information-processing requirements can be systematically varied to assess ordinal levels of functional capacity. Six tasks, titled DRESS, SHOP, TOAST, PHONE, WASH and TRAVEL comprise the test. For each task, standard equipment, set-up and methods of administration are required. A gross level score is determined for each of the six tasks; these scores are then added for a total score and averaged (divided by 6) to determine the functional level and mode. The CPT was initially developed as a research instrument, to be used in longitudinal study of functional change and for serial assessment to detect change in response to a pharmacologic or environmental intervention. It currently serves as the functional assessment for the GRECC diagnostic work-up and has proved to be useful in the assessment of patients, with a variety of diagnoses, to predict and explain capabilities to function in various contexts.
