The CPT is a standardized performance-based assessment initially developed as a research instrument for baseline and serial measurements of occupational performance.
Common daily activities are used to measure working memory and executive control function that underlie occupational performance and behavior. The CPT is used to explain and predict the client's capacity to function in various contexts and to guide intervention plans, as well as to measure and track the severity of a cognitive-functional disability such as with Alzheimer's disease.
