Brief Description of Instrument – Measures performance in bathing, dressing, going to the toilet, transferring, continence and feeding. Originally developed to study results of treatment and prognosis in aging and chronic illness.

Scoring and Interpretation – See scoring guide published in original citation. Scoring assigns an overall letter grade for ADL performance ranging from A (most independent) to G (most dependent).
Construct Validity – Able to classify patients who had a wide range of illnesses. Testing demonstrated an ordered pattern in the performance of ADLs. Degree of assistance related to dependence ADL score.
Responsive to Change Over Time – Demonstrated responsiveness to recovery after hip fracture.
