A Theoretical Model of Functional Performance in Persons with Alzheimer Disease

Abstract

This paper reports on a qualitative study that defined a theoretical model as a first step in the development of a functional performance measure for clients with Alzheimer disease. A consensus panel of caregivers used the grounded theory approach to identify the basic sub-components of functional performance that are affected by Alzheimer disease. A model of functional performance which can be applied to any basic activity of daily living was derived from these data. The model comprised three axes: behavioural, environmental and quality of performance. A second panel of caregivers validated the model. This study provided the framework for the Functional Performance Measure to be tested in a subsequent study.
