This assessment validation study aimed to explore age-related norms, known groups, and concurrent validity of the newly developed Chicago-Quick Hand Function Test (C-QHFT) (Kumar, 2024). This non-experimental quantitative study recruited 47 participants with hand impairments (from hand clinics and the community) and matched participants to people without hand impairments from a previous study (Kumar, 2024). Results indicate age differences between age groups as well as moderate to high correlations between the C-QHFT and the Corbett Targetted Coin Test (CTCT), Ranging from .539-.833 (p =<.001). Group differences between people with and without hand impairments show clinical significance (.10), but not statistically significant differences. Findings show promise for the use of the C-QHFT as a potential tool for people with hand injuries; however, future research might consider a larger sample size and a more focused sample with respect to diagnostic categories. Additionally, future studies should evaluate the predictive validity of the tool as an outcome measure for OTs working with clients with hand impairments.
