The Jebsen Taylor Test of Hand Function: A Pilot Test–Retest Reliability Study in Typically Developing Children

ABSTRACT Aims: The aim of this pilot study was to evaluate reproducibility of the Jebsen Taylor Test of Hand Function (JTTHF) in children. Methods: Eighty-seven typically developing children 5 to 10 years old were included from five Outside School Hours Care centers in the Greater Brisbane Region, Australia. Hand function was assessed on two occasions with a modified JTTHF, then reproducibility was assessed using Intraclass Correlation Coefficient (ICC [3,1]) and the Standard Error of Measurement (SEM). Results: Total scores for male and female children were not significantly different. Five-year-old children were significantly different to all other age groups and were excluded from further analysis. Results for 71 children, 6 to 10 years old were analyzed (mean age 8.31 years (SD 1.32); 33 males). Test–retest reliability for total scores on the dominant and nondominant hands were ICC 0.74 (95% CI 0.61, 0.83) and ICC 0.72 (95% CI 0.59, 0.82), respectively. ‘Writing’ and ‘Simulated Feeding’ subtests demonstrated poor reproducibility. The Smallest Real Difference was 5.09 seconds for total score on the dominant hand. Conclusions: Findings indicate good test–retest reliability for the JTTHF total score to measure hand function in typically developing children aged 6 to 10 years.
