Home Environmental Assessment Protocol-Revised Initial Psychometrics: A Pilot Study

Efficient home assessments are needed for persons with dementia and their caregivers. Pilot studies to establish a content validity index (CVI), measure concurrent criterion validity, and examine test-retest reliability of the Home Environment Assessment Protocol-Revised (HEAP-R). Six experts reviewed the tool and scored content validity items. Twenty-one caregiver/person with dementia dyads engaged with HEAP and HEAP-R to examine concurrent criterion validity. Seventeen occupational therapists viewed 10 videos of home environments to examine reliability. The CVI score was .980. Concurrent criterion validity for domains: hazards (r =.792), adaptations (r = .742), clutter (r = .843), and comfort (r = .958). Test-retest reliability: hazards (r = .820), adaptations (r = .887), visual cues (r = .487), and clutter (r = .696). Pilot data suggest the HEAP-R has preliminary content and concurrent criterion validity and test-retest reliability. Robust psychometric analysis is needed prior to use in clinical practice.
