Development of the Functional Assessment Taxonomy.

Abstract

The development of the Functional Assessment Taxonomy is described and the taxonomy is presented. The taxonomy provides a method to classify and organize constructs that are used to assess the functional abilities of people with medical impairments to determine work disability. The taxonomy has 131 constructs that are organized into 33 conceptual factors that are nested in 5 domains. Each construct is defined and is categorized in terms of the work disability model and the unit of analysis that is commonly used to measure the construct. The use of the taxonomy in the Disability Methodology Redesign Project is described. Other possible uses for the taxonomy are presented.
