Measuring the Activity Patterns of Adults with Severe Disabilities Using the Resident Lifestyle Inventory

Abstract
Outcome measures that document activity patterns provide an empirical basis for improving the lifestyles of adults with severe disabilities. This report provides a psychometric assessment of an instrument, the Resident Lifestyle Inventory (RLI), that can be used to measure the activities performed by such persons. In a series of three assessments the congruent validity (Assessment 1), test-retest reliability (Assessment 2), and social validity (Assessment 3) of the RLI were analyzed to determine its acceptability as a measurement instrument for documenting activity patterns. Results from the three assessments demonstrated that the RLI is a psychometrically acceptable measure that is used accurately by residential programs. It is perceived by support staff to be a useful strategy for improving lifestyle quality. Implications of this report are provided for the role of outcome measures in community-based residential support, the individualized plan development process, and future research.
