Abstract: BACKGROUND: To encourage self-determination and address health disparities among persons with intellectual and developmental disabilities, clinicians and researchers rely on self-reported measures like health-related quality of life (HRQoL). This study evaluated the psychometric properties of a theory-driven self-reported HRQoL measure for adults requiring mild to moderate support related to intellectual and developmental disabilities. METHOD: 224 volunteers completed 42 quality of life items developed with extensive input from persons with intellectual and developmental disabilities, family members/caregivers, and providers. The 5-point Likert scale format with visual images of fluid-filled cups represented the range of responses. RESULTS: Exploratory and Unrestricted Factor Analyses yielded 16 HRQoL items with 4 subscales: Functional Well-Being, Emotional Well-Being, Social Well-Being, and Healthy Decision-making. The HRQoL-IDD explained 62.8% of variance, had satisfactory internal consistency (0.73-0.83), stability of reponses, and reading level (2nd grade, ages 7-8). CONCLUSIONS: The HRQoL-IDD is a promising measure of self-reported HRQoL for use in community-based settings for persons requiring mild to moderate support related to intellectual and developmental disabilities.
