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.
