To me this is totally wrong way to measure it. It is a binary question. ARE YOU 100% RECOVERED? YES/NO?

Abstract: 

Study examined the underlying structure of the Stroke Impact Scale 3.0 (SIS-3.0), a promising outcome measure of health-related quality of life (HRQOL) for clients with stroke, by comparing the currently available eight- and four-domain structures simultaneously. This was a secondary data analysis of responses to the SIS-3.0 from a previous psychometric validation study. In that study, 263 patients with stroke were recruited from the rehabilitation wards (inpatients) and neurology and rehabilitation clinics (outpatients) of five general hospitals in northern and southern Taiwan. Confirmatory factor analysis was used to examine the eight- and four-domain structures of the SIS-3.0. Four fit indices were considered simultaneously to examine the model fits of both structures: (1) chi-squared value adjusted for model complexity, (2) comparative fit index, (3) root mean square (RMS) error of approximation, and (4) standardized RMS residual. The eight- and four-domain structures of the SIS-3.0 were not supported by all four indices. The unidimensionality of each domain in the two structures was not supported. Neither the eight- nor the four-domain structure of the SIS-3.0 was supported, suggesting that scores may not provide valid assessments of HRQOL in clients with stroke. Further modification and validation of the SIS-3.0 are warranted. These findings suggest that the eight- and four-domain scores of the SIS-3.0 may not be valid. Therefore, until more supporting evidence is developed, these scores should be interpreted cautiously regarding clients’ HRQOL; alternatively, other measures could be used.
