Diabetic Peripheral Neuropathy (DPN) is a prevalent complication of Type 2 Diabetes Mellitus (T2DM), leading to hand function impairments that affect daily activities and quality of life. Despite its significance, no culturally adapted tool exists for assessing hand-related activity limitations in the Malay-speaking population. This study aimed to translate, culturally adapt and validate the Duruöz Hand Index (DHI) for Malaysians with DPN.
A cross-sectional study was conducted in two phases: (1) translation and cultural adaptation of the DHI into Malay and (2) evaluation of its psychometric properties. Content validity was assessed by a panel of nine experts using the Content Validity Index (CVI). Face validity was evaluated through a pilot test with 10 individuals with DPN. Internal consistency (Cronbach's alpha) and test-retest reliability (Intraclass Correlation Coefficient, ICC) were measured in 30 participants with DPN. Known-group validity was examined by comparing DPN participants with healthy individuals.
The content validity of the Malay-DHI was excellent and face validity confirmed that the Malay-DHI was clear and comprehensible. Internal consistency was strong across all categories (α = 0.84-0.97). Test-retest reliability demonstrated excellent stability (ICC = 0.996-1.000). Known-group validity showed a significant difference between individuals with DPN and healthy individuals (Z = -6.93, < .001).
The Malay version of the DHI demonstrated strong validity and reliability, making it a culturally relevant and robust tool for assessing hand function in individuals with DPN. This tool may facilitate targeted rehabilitation interventions and improve clinical outcomes.
糖尿病周围神经病变（DPN）是2型糖尿病（T2DM）的一种常见并发症，会导致手部功能受损，影响日常活动和生活质量。尽管其具有重要意义，但在马来语人群中，尚无经过文化适应性调整的工具来评估与手部相关的活动受限情况。本研究旨在对马来西亚DPN患者翻译、进行文化适应性调整并验证Duruöz手部指数（DHI）。
进行了一项分为两个阶段的横断面研究：（1）将DHI翻译成马来语并进行文化适应性调整；（2）评估其心理测量特性。由九名专家组成的小组使用内容效度指数（CVI）评估内容效度。通过对10名DPN患者进行预试验来评估表面效度。在30名DPN患者中测量内部一致性（Cronbach's α）和重测信度（组内相关系数，ICC）。通过比较DPN患者与健康个体来检验已知组效度。
马来语版DHI的内容效度极佳，表面效度证实马来语版DHI清晰易懂。所有类别中的内部一致性都很强（α = 0.84 - 0.97）。重测信度显示出极佳的稳定性（ICC = 0.996 - 1.000）。已知组效度显示DPN患者与健康个体之间存在显著差异（Z = -6.93，P <.001）。
马来语版DHI显示出很强的效度和信度，使其成为评估DPN患者手部功能的具有文化相关性且可靠的工具。该工具可能有助于针对性的康复干预并改善临床结果。
