Jebsen Hand Function Test (JHFT)

Overview
A literature search was conducted to identify all relevant publications on the psychometric properties of the Jebsen Hand Function Test (JHFT). While studies have been conducted with other patient groups, this review specifically addresses the psychometric properties relevant to patients with stroke. At the time of publication five studies were identified: three relating to the JHFT, and one each for the JHFT (Portuguese version) and the Modified Jebsen Hand Function Test (MJT).
Floor/Ceiling Effects
No studies have examined the floor and ceiling effects of the JHFT.
Reliability
Internal consistency Ferreiro, dos Santos, & Conforto (2010) examined the Cronbach’s alpha (writing: r=0.812, ?=0.844; card turning r=0.857, ?=0.632; small common objects r=0.657, ?=0.651; simulated feeding r=0.813, ?=0.646; checkers r=0.712, ?=0.633; large light objects r=0.849, ?=-0.681; large heavy objects r=0.898, ?=0.687). Inter-rater reliability Ferreiro, dos Santos, & Conforto (2010) examined the Inter-rater reliability (writing, ICC=0.999; card turning, ICC=0.977; small common objects, ICC=0.998; simulated feeding, ICC=0.991; checkers, ICC=0.995; large light objects, ICC=0.988; large heavy objects, ICC=0.991). Intra-rater reliability Ferreiro, dos Santos, & Conforto (2010) examined intraclass correlation coefficient (ICC). Test-retest reliability Jebsen et al. (1969) examined Test-retest reliability (writing: r=0.67, 0.84; cards: r=0.91, 0.78; small objects: r=0.93, 0.85; simulated feeding: r=0.92, 0.60; checkers: r=0.99, 0.91; large light objects: r=0.89, 0.67; large heavy objects: r=0.89, 0.92, dominant and non-dominant hands respectively). Bovend’Eerdt et al. (2004) examined the Pearson’s correlation coefficient.
Validity
Content No studies have examined the content validity of the JHFT Criterion Predictive No studies have examined the predictive validity of the JHFT. Concurrent Beebe & Lang (2009) examined the correlations with grip strength (r=0.79-0.81), pinch strength (0.60-0.79), ARAT (r=0.87-0.95), NHPT (0.84-0.97) and SIS-Hand (0.61-0.83) at all time points. Note: the study did not use the first task of the JHFT (writing a sentence) due to its dependence on hand dominance and education level. Beebe & Lang (2007) examined Pearson’s correlation coefficient. Correlations between the MJT and UMAQS were not significant at either time point.

No studies have examined the construct validity of the JHFT. Known Groups Ferreiro et al. (2010) reported no significant difference in scores on the JHFT (Portuguese version) according to education level or hand dominance in a sample of 40 patients with stroke.

Responsiveness
Beebe & Lang (2009) measured the responsiveness responsiveness from 1 to 3 months post-stroke (ES=0.69) and from 3 to 6 months post-stroke (ES=0.73). Sensitivity & Specificity No studies have examined the specificity of the JHFT.
