摘要 |
Purpose: To assess the clinimetric
properties of the Stroke Self-Efficacy Questionnaire (SSEQ) and estimate the
minimal detectable change (MDC) and minimal clinically important difference
(MCID) from the database of our randomized controlled trials (RCT) of
individuals receiving stroke rehabilitation. Methods: We retrieved the pre- and
post-intervention scores of the SSEQ and Stroke Impact Scale (SIS) from 80 stroke
survivors. The analysis of clinimetric properties
was performed using: (1) confirmatory factor analysis and item response
theory modeling (IRT) for construct validity; (2) standardized response mean
and Glass's delta for responsiveness; (3) MDC based on the standard deviation
(SD) or standard error of measurement (SEM) of the SSEQ change scores; (4)
MCID determined by the external anchor-SIS; (5) conditional MDC (cMDC) derived from the IRT analysis. Results: There was a bi-factorial construct with
excellent model-data fit and marked responsiveness. The MDC determined by the
SD and SEM were 1.5 and 3.0, respectively, and the MCIDs were 3.3 and 3.7. Conclusions: This study confirmed that SSEQ is a valid and reliable assessment tool for patients receiving stroke rehabilitation. We also provided practical threshold values, especially demonstrating the benefit of using individualized cMDC, to help clinicians better interpret the change in the SSEQ scores. |
