Abstract

This study tested the psychometric properties of an electronic Family Quality of Life Survey (eFQOLS) when used with families of individuals with disabilities and/or chronic health conditions. Data gathered from 272 family caregivers using the eFQOLS were subjected to reliability analysis, correlation analysis, and confirmatory factor analysis to test the internal consistency of the scales, as well as criterion and construct validity of the internal structure of the scale. Testing factor structures of the item-level domain models indicated that initiative and stability had low factor loadings in many domains. As a result, these items were deleted from the subscales. The subscale-level FQOL factor structure demonstrated a good fit after two adjustments. The internal consistency of the 27-item total FQOL scale was excellent (α = .93), while that of the subscales ranged from moderate to strong (α = .69 to .90). The eFQOLS had a moderate degree of construct validity, good criterion validity, and reliability when used with diverse families across the lifespan. Additional research is needed to continue refining the survey with a more heterogenous sample.
