Product Description:
OBJECTIVE: The aim of this study was to determine the conceptual framework, item pool, and psychometric properties of a new function-neutral measure of health-related quality-of-life (HRQOL). DESIGN: This is an expert panel review of existing measures of HRQOL and development of a conceptual model, core constructs, and item pool and a validation by experts in specific disabilities and in cultural competence. Items were cognitively tested, pilot tested for functional bias, field tested with a national sample of adults with various limitations, and reliability tested via repeat administration. Final item selection was based on analyses of factor structure, demographic bias, variance in likelihood of endorsement, and item-total correlation. Psychometric properties were demonstrated through differential item functioning analyses, factor analyses, correlations, and item response theory analyses. RESULTS: The results supported a four-domain conceptual model of HRQOL
