Duke Activity Status Index (DASI) is a widely used tool to assess functional capacity among patients, but there is no Sinhala version validated for patients in Sri Lanka. This study aimed to cross-culturally adapt and test the validity and reliability of the Sinhala version of DASI (DASI-S).
The translation and cross-cultural adaptation of the DASI questionnaire were conducted following the standard guidelines. It was pre-tested on ten pre-operative patients and further modified. The construct validity and reliability of DASI-S were evaluated by administering the modified final DASI-S, which comprised 12 items, along with the physical functioning sub-scale of the 36-item short-form health survey (SF-36), consisting of 10 items to eighty-one patients who were awaiting non-cardiac surgeries at university surgical wards, National Hospital of Sri Lanka (NHSL), and Colombo North Teaching Hospital (CNTH), Sri Lanka. Reliability was assessed through Cronbach alpha, while the validity was evaluated using factor analysis and Spearman's correlation. The ethical approval was obtained from the Ethics Review Committee, Faculty of Medicine, University of Colombo, Sri Lanka.
The mean age of the participants was 46.2 (± 16.6) years and the majority were females (54.3%). The mean height, weight, and body mass index of the sample were 160.5 (± 9.6) cm, 60.3 (± 11.9) kg, and 23.4 (± 4.5) kgm respectively. The Cronbach's alpha coefficient for the internal consistency of DASI-S was 0.861. The concurrent validity of DASI-S was substantiated by positively correlating (p < 0.01, r = 0.466) with the physical sub-scale of SF-36. There was a significant difference (p < 0.01) in the total score of DASI-S between the two age groups.
Sinhala version of the DASI appears to be a valid, reliable and easy-to-administer tool to assess functional capacity among patients who are awaiting non-cardiac surgeries.
杜克活动状态指数（DASI）是一种广泛用于评估患者功能能力的工具，但尚无针对斯里兰卡患者验证的僧伽罗语版本。本研究旨在对DASI的僧伽罗语版本（DASI-S）进行跨文化改编，并测试其有效性和可靠性。
按照标准指南对DASI问卷进行翻译和跨文化改编。在10名术前患者中进行预测试并进一步修改。通过对修改后的最终DASI-S（包含12个项目）以及36项简短健康调查问卷（SF-36）的身体功能子量表（由10个项目组成）进行施测，对81名在斯里兰卡国立医院（NHSL）和科伦坡北部教学医院（CNTH）大学外科病房等待非心脏手术的患者评估DASI-S的结构效度和可靠性。通过Cronbach阿尔法系数评估可靠性，使用因子分析和斯皮尔曼相关性评估有效性。获得了斯里兰卡科伦坡大学医学院伦理审查委员会的伦理批准。
参与者的平均年龄为46.2（±16.6）岁，大多数为女性（54.3%）。样本的平均身高、体重和体重指数分别为160.5（±9.6）厘米、60.3（±11.9）千克和23.4（±4.5）千克/米²。DASI-S内部一致性的Cronbach阿尔法系数为0.861。DASI-S与SF-36身体子量表呈正相关（p<0.01，r=0.466），证实了其同时效度。两个年龄组之间DASI-S总分存在显著差异（p<0.01）。
DASI的僧伽罗语版本似乎是一种有效、可靠且易于实施的工具，可用于评估等待非心脏手术患者的功能能力。
