Abstract
The aim of this cohort study was to evaluate the concordance of the Sickness Impact Profile for Nursing Homes (SIP- NH) and Sickness Impact Profile (SIP) in classifying change. Subjects consisted of 194 consecutive long- stay nursing home residents at one academic department of the V.A. and in 8 community proprietary nursing homes in San Antonio, Texas. They were to have more than 3 months residency; to be ⩾61 years; and to be dependent in at least 2 ADLs with an MMSE score of ⩾15. Subjects were administered a 128- item SIP and a reduced 66- item SIP- NH at baseline and 4, 8, and 12- month follow- up. At each follow- up, subjects were classified into 3 mutually exclusive change categories using a change score of ⩾5 points. Concordance of the classification of subjects by the SIP- NH and SIP was evaluated. The misclassification rate as well as its direction was also assessed. Both instruments classified a little over one- quarter of the subjects as better, over a third as being unchanged, and another third as being worse at the four- month follow- up. More subjects were classified as worse by both instruments at 8 and 12 months. All kappas ranged from 0.52 to 0.78, indicating good to excellent agreement. Overall, the SIP- NH characterized persons as changed more often than the SIP with no systematic directional bias. In conclusion, the SIP- NH was concordant with the SIP in classifying change in subjects. However, we cannot say which of the two is better for detecting change. Future research must focus on defining a change score which has clinical meaning, and evaluate responsiveness to change. (Aging Clin. Exp. Res. 7: 228–233, 1995)
