Abstract

Assessment of functional status in stroke patients is of major importance in both clinical practice and outcome studies. The Frenchay Activities Index has been developed specifically for measuring disability and handicap in stroke patients. The purpose of the study was to evaluate the metric properties of this instrument and to obtain normal values in a group of unselected elderly subjects. The Frenchay Activities Index was tested in a group of stroke patients and a group of unselected subjects aged 65 or older. The functional status of the stroke patients was measured 26 weeks after stroke. Their prestroke status was registered retrospectively. Reliability and validity of the instrument were assessed. The mean scores in the prestroke, poststroke, and control group demonstrated differences in functional status. The reliability of unweighted scores (range of Cronbach's alpha-coefficients, 0.78 to 0.87) was sufficient. The construct validity was supported by meaningful correlations between the Frenchay Activities Index and scores on the Barthel Index and Sickness Impact Profile. Principal-components analysis indicated that the Frenchay Activities Index showed two traits: instrumental disability and some aspects of handicap. The reliability of the instrument could be improved by deleting two items and by creating two subscale scores: domestic and outdoors activities. The Frenchay Activities Index is a useful stroke-specific instrument to assess functional status. Completion of the questionnaire is easy and takes only a few minutes. Currently, the instrument is suitable for use in patient care and cross-sectional, descriptive studies
