A Rasch analysis was used to assess the unidimensionality and appropriateness of the
scoring level of a 13-item self-perceived change in quality of life scale (CQOL) for stroke
patients. A total of 158 patients with mild stroke completed the CQOL themselves at
home. The results showed that a unidimensional CQOL can be created by deleting the
three items related to speaking, vision, and thinking. The 4 scoring categories of the
shortened scale were deemed appropriate from the analysis. These results provide
preliminary evidence of the 10-item CQOL in assessing self-perceived change in quality
of life in stroke patients. Further studies are needed to examine the test-retest reliability,
criterion validity, and responsiveness of the 10-item CQOL in stroke patients.
