In-hand manipulation is an integral component of human hand function that we use in daily tasks such as buttoning, writing, eating, tying shoelaces, using a smartphone, zipping, unzipping, picking up small objects, etc. The hand function literature suggests that no outcome measure (OM) exists that assesses finger-to-palm translation, palm-to-finger translation, stabilization, or cognitive contribution to hand function. The development of the Chicago-Quick Hand Function Test (C-QHFT) fills this gap. The purpose of the study is to explore the reliability and validity of the C-QHFT and identify normative data on C-QHFT in healthy adults. The study used a quantitative-focused, sequential and explorative design involving four phases to establish the tool’s psychometric properties and used convenient sampling to recruit participants. Phase I assessed the face validity, content validity, and interrater reliability of C-QHFT. Phase II addressed issues from Phase I and reexamined interrater reliability. Phase III collected normative data, evaluated concurrent validity with the Nine-Hole Peg Test (NHPT), and explored intra-rater reliability. Phase IV analyzed test-retest reliability. Various analyses used in the study included descriptive, content validity index (CVI), intraclass correlation, Pearson correlation, t-tests and ANOVA. Results indicated high content validity (CVIs of 0.9 to 1), excellent interrater (ICC = 0.99) and intra-rater reliability (ICC = 0.95), and good concurrent validity with the NHPT. Normative data analysis on 273 participants showed significant age-related differences in C-QHFT scores. The study concluded the C-QHFT is a valuable OM for assessing hand function comprehensively. By incorporating the C-QHFT, occupational therapists (OTs) can assess hand function comprehensively. The addition of C-QHFT as an outcome measure enhances the assessment of hand function by OT, offering a comprehensive and efficient tool for practitioners.
