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

Abstract

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.
