Turkish version of modified Hand Mobility in Scleroderma test: A translation and validation study.

OBJECTIVE: Hand Mobility in Scleroderma (HAMIS) is a hand function test used to determine the degree of dysfunction of hand movements. The Modified Hand Mobility in Scleroderma (mHAMIS), on the other hand, was developed later and consists of 4 items. The aim of this study was to determine the reliability and validity of mHAMIS. METHODS: This study included a total of 39 patients with systemic sclerosis (SSc) who were assessed with mHAMIS. The Cronbach's α coefficient, Kappa concordance, and intraclass correlation were respectively used to assess the internal consistency, intra- and inter-observer agreement, and inter-observer reliability of the test. The correlation between the Health Assessment Questionnaire (HAQ), the Duruoz Hand Index (DHI), and the Turkish version of mHAMIS were evaluated. RESULTS: The internal consistency of the test items was between .912 and .939. The total internal consistency of the test was excellent, with a Cronbach's alpha value of .954. The intra- and inter-observer agreement were good, with Kappa values of 0.954 (95% CI 0.89-1.6) and 0.965 (95% CI 0.82-1.4), respectively. The inter-observer reliability was 0.966 (95% CI 0.936-0.982; P<.0001). There was a strong correlation between DHI, HAQ, and mHAMIS (r: .7-.8). CONCLUSION: The Turkish version of the mHAMIS test showed good intra- and inter-observer agreement, intra-observer reliability, and internal consistency. This test is a reliable and valid tool to assess hand functions in Turkish SSc patients.
