Activities of Daily Living Assessment among Nursing Home Residents with Advanced Dementia: Psychometric Reevaluation of the Bristol Activities of Daily Living Scale.

The purpose of this study was to conduct psychometric reevaluation of the Bristol Activities of Daily Living Scale (BADL) among a population logistically difficult to observe beyond cross-sectional analysis: nursing home residents with advanced dementia (AD). Data from observation-based measures were collected by nursing home staff at two intervals within a three-month time frame among 43 residents identified with AD via medical records and nursing home staff. Three broad properties of BADL were examined: factor structure, reliability, and validity.
