Abstract

Objective This paper's purpose was to assess the reliability, measurement error, construct validity, and responsiveness of the Spanish version of the QuickDASH for outcomes assessment in Carpal Tunnel Syndrome (CTS).

Methods A total population of 40 patients was diagnosed with CTS. The Spanish versions of the QuickDASH, CTS-AL, and EQ-5D were completed by the patients 1 week, the day before surgery, and 3 months after the surgery. Internal consistency was analyzed by Cronbach α coefficient. The intraclass correlation (ICC2,1), Lin's coefficient (CCC), and Bland and Altman Limit of Agreement (LoA) were used for the absolute agreement assessment, and the non-parametric Passing-Bablock (P-B) were used to assess constant and proportional systematic bias between the measurements. Cross-sectional precision was analyzed with the Standard Error of the Measurement (SEM). Longitudinal precision for the test-retest reliability coefficient was analyzed with the Standard Error of the Measurement difference (SEMdiff) and the Minimal Detectable Change at 90% (MDC90) and 95% (MDC95) confidence levels. For assessing construct validity, we hypothesized that the QuickDASH would have a strong positive correlation with the CTS-AL and a moderate negative correlation with the EQ-5D Index, using a Pearson correlation coefficient (r) with a level of significance of 0.05.

Results Cronbach coefficient was 0.912. ICC2,1 and CCC showed a high absolute agreement (0.868 and 0.738 respectively). The P-B regression showed no significant constant and proportional differences between the two administrations of QuickDASH. The QuickDASH showed a responsiveness (ES = 2.1; SRM = 1.97) lower than the CTS-AL (ES = 3.53; SRM = 3.50), and higher than the EQ-5D Index (ES =0.78; SRM =0.83).

Conclusion The Spanish (Spain) version of the QuickDASH instrument presented a good level of reliability, construct validity, and responsiveness for outcomes assessment in CTS.
