ABSTRACT
Introduction: Duruoz Hand Index (DHI) is a functional disability scale that can be used successfully to assess the functional disabilities of the hands. The hands are frequently involved in diabetic patients, due to soft tissue thickening in these areas referred to as atrophy, leading to wasting of the muscles. The DHI is currently not available in Gujarati language so there is a need to develop a scale which can be used by the Gujarati language speaking population.
Materials & methods: An observational study was conducted in the Ahmedabad city. The scale was translated into Gujarati language through double forward and backward translation. Each question was scored by experts as accepted, rejected or accepted with modification. The reliability and validity of the finalized Gujarati version was subsequently completed with the sample size of 20 participants including both the genders in type II diabetes mellitus patients. Face and content validity along with internal consistency and test-retest reliability was also examined.
Result: In the validation process of Gujarati version of DHI total 18 questions existed; one question was accepted with modification. The Gujarati version of the DHI has high internal consistency (Cronbach’s α=0.890) and test-retest reliability (intra-class correlation coefficient=0.809, 95% CI: 0.58, 0.94).
Conclusion: The translation of the DHI into a Gujarati version was successful in preserving the semantic and measurement properties of the original version and was valid and reliable scale for the Gujarati population.
Key words: DHI, Type II Diabetes Mellitus, Validity, Reliability.
