Abstract

Background: Olfactory disorders (OD) are an umbrella term for a diverse group of smell problems. Numerous tests and questionnaires have been formulated to identify and test the severity of smell impairment, which is not readily available or translated for the Malaysian population. This study aimed to translate the Questionnaire for Olfactory Disorders (QOD) and validate and test the reliability of the Malay Questionnaire for Olfactory Disorders (mQOD). Methods: This cross-sectional study was conducted in two tertiary centres. A forward and backward translation was conducted for the QOD. The translated questionnaire was distributed to subjects with self-reported smell disorders on days 1 and 7. Internal consistency was analysed using Cronbach’s alpha and test-retest reliability was tested with an intraclass correlation coefficient. Confirmatory factor analysis was performed to test construct validity. Results: A total of 375 participants were recruited, 52 dropped out and 323 completed the questionnaire a second time. The Cronbach’s alpha coefficient was 0.537 for parosmia (P), 0.892 for life quality (LQ), 0.637 for sincerity (S) and 0.865 for visual analogue score (VAS). The intraclass correlation coefficient (ICC) for domain scores was > 0.9, while the ICC for all items was good to excellent. A three-factor model for mQOD showed an acceptable fit with indices chi-square value (CMIN)/degree of freedom (DF) = 3.332, Tucker-Lewis fit index (TLI) = 0.923, comparative fit index (CFI) = 0.939, root mean square error of approximation (RMSEA) = 0.079 and standardised root mean square residual (SRMR) = 0.0574. Conclusion: The mQOD is a valid and reliable tool for assessing OD in patients

马来嗅觉障碍问卷的有效性和可靠性

背景：嗅觉障碍（OD）是各种嗅觉问题的总称。目前已经制定了许多测试和问卷来识别和测试嗅觉障碍的严重程度，但这些测试和问卷并不适合马来西亚人使用或翻译。本研究旨在翻译嗅觉障碍问卷（QOD），并验证和测试马来嗅觉障碍问卷（mQOD）的可靠性。研究方法这项横断面研究在两个三级医疗中心进行。对 QOD 进行了正向和反向翻译。在第 1 天和第 7 天向自述有嗅觉障碍的受试者发放翻译后的问卷。采用 Cronbach's alpha 分析了内部一致性，并采用类内相关系数测试了测试-再测可靠性。此外，还进行了确认性因子分析，以检验构建有效性。结果：共招募了 375 名参与者，52 人退出，323 人第二次完成了问卷。副作用（P）的 Cronbach's alpha 系数为 0.537，生活质量（LQ）的 Cronbach's alpha 系数为 0.892，真诚度（S）的 Cronbach's alpha 系数为 0.637，视觉模拟评分（VAS）的 Cronbach's alpha 系数为 0.865。领域得分的类内相关系数（ICC）大于 0.9，而所有项目的 ICC 均为良好至优秀。mQOD 的三因素模型显示了可接受的拟合度，指数奇平方值 (CMIN)/ 自由度 (DF) = 3.332，塔克-刘易斯拟合指数 (TLI) = 0.923，比较拟合指数 (CFI) = 0.939，均方根近似误差 (RMSEA) = 0.079，标准化均方根残差 (SRMR) = 0.0574。结论mQOD 是评估患者 OD 的有效、可靠工具

期刊介绍： The Malaysian Journal of Medical Sciences (MJMS) is a peer-reviewed, open-access, fully online journal that is published at least six times a year. The journal’s scope encompasses all aspects of medical sciences including biomedical, allied health, clinical and social sciences. We accept high quality papers from basic to translational research especially from low & middle income countries, as classified by the United Nations & World Bank (https://datahelpdesk.worldbank.org/knowledgebase/ articles/906519), with the aim that published research will benefit back the bottom billion population from these countries. Manuscripts submitted from developed or high income countries to MJMS must contain data and information that will benefit the socio-health and bio-medical sciences of these low and middle income countries. The MJMS editorial board consists of internationally regarded clinicians and scientists from low and middle income countries.
