The Malay spoken in Brunei a South East Asian country where Malay is the national language is distinctive and different from Malay spoken in Malaysia, Singapore and Indonesia. This study aimed to develop a Brunei Malay version of the 5-level EQ-5D questionnaire (EQ-5D-5L) and to assess its psychometric properties among patients with type 2 diabetes mellitus (T2DM).
The Brunei Malay EQ-5D-5L was developed by culturally adapting two existing Malay versions. A total of 154 Bruneians with T2DM completed the questionnaire in two different points of time with one week apart. Known-groups validity of the utility-based EQ-5D-5L index and visual analogue scale (EQ-VAS) was evaluated by comparing subgroups of patients known to differ in health status. Test-retest reliability was assessed using the intraclass correlation coefficient (ICC) or Cohen's kappa.
As hypothesized, patients known to have 'better' health had higher EQ-5D-5L index scores than those having 'worse' health in all 7 known-groups comparisons. The hypothesized difference in the EQ-VAS scores was observed in only 4 of the 7 known-groups comparisons. Kappa values ranged from 0.206 to 0.446 for the EQ-5D-5L items; the ICC value for the EQ-5D-5L index and EQ-VAS was 0.626 and 0.521, respectively.
The utility-based EQ-5D-5L index appears to be valid and reliable for measuring the health of Brunei patients with T2DM. The validity of the EQ-VAS in Brunei requires further investigation.
文莱是一个东南亚国家，马来语为其国语，文莱所讲的马来语独具特色，与马来西亚、新加坡和印度尼西亚所讲的马来语有所不同。本研究旨在开发文莱马来语版的5级EQ-5D问卷（EQ-5D-5L），并评估其在2型糖尿病（T2DM）患者中的心理测量特性。
通过对两个现有的马来语版本进行文化调适，开发了文莱马来语版的EQ-5D-5L。共有154名患有T2DM的文莱人在两个不同时间点完成了问卷，时间间隔为一周。通过比较已知健康状况不同的患者亚组，评估基于效用的EQ-5D-5L指数和视觉模拟量表（EQ-VAS）的已知组效度。使用组内相关系数（ICC）或科恩kappa系数评估重测信度。
正如所假设的，在所有7组已知组比较中，已知健康状况“较好”的患者的EQ-5D-5L指数得分高于健康状况“较差”的患者。在7组已知组比较中，只有4组观察到了EQ-VAS得分的假设差异。EQ-5D-5L项目的kappa值范围为0.206至0.446；EQ-5D-5L指数和EQ-VAS的ICC值分别为0.626和0.521。
基于效用的EQ-5D-5L指数似乎对于测量文莱T2DM患者的健康状况是有效且可靠的。EQ-VAS在文莱的效度需要进一步研究。
