Abstract

Background

Knee osteoarthritis (KOA) is common in Vietnam, affecting about 34 % of individuals over 40 years of age. The Knee Injury and Osteoarthritis Outcome Score (KOOS) is an internationally recognized patient-reported outcome used to assess the impact of KOA but it is not yet available in Vietnamese.

Objective

This study aimed to translate the KOOS into Vietnamese and assess the psychometric properties of the translation (KOOS-V).

Methods

The translation process involved forward/back translation, expert review and cognitive interviews for pretesting. Content validity was assessed by seven experts using the Content validity Index (CVI). A sample of 133 Vietnamese KOA patients (mean age: 63.7 years, 83 % female) completed the KOOS-V, Short Form 36 Health Survey (SF-36) and Numeric Pain Rating Scale (NPRS), and 67 of them were re-assessed after 5–8 days. Psychometric analyses included internal consistency, test-retest reliability, construct validity and cross-cultural comparison of KOOS-V subscales.

Results

KOOS-V exhibited excellent content validity (CVI = 0.86–1.00), satisfactory internal consistency (Cronbach's α = 0.70–0.98) and good to excellent test-retest reliability (ICC = 0.77–0.90). Construct validity was confirmed by moderate to strong correlations with SF-36 Physical Functioning (Spearman's ρ = 0.66 to 0.82) and moderate correlations with NPRS (ρ = −0.49 to −0.62). The cross-cultural comparison showed that the KOOS subscales in Vietnam presents the same challenge as in other cultures.

Conclusions

The KOOS-V is a reliable, valid tool for assessing the functional impact of KOA in Vietnamese patients, contributing to its broader use worldwide in clinical and research settings.

膝关节骨性关节炎患者膝关节损伤和骨性关节炎结果评分（KOOS）越南语版的跨文化改编和验证

膝骨关节炎（KOA）在越南很常见，影响了大约34%的40岁以上的人。膝关节损伤和骨关节炎预后评分（kos）是国际公认的患者报告的结果，用于评估KOA的影响，但尚未在越南使用。目的对越南语“KOOS- v”进行翻译，并评估翻译后的心理测量学特征。方法采用前译/后译、专家评审和认知访谈法进行预测。内容效度由7位专家使用内容效度指数（CVI）进行评估。133例越南KOA患者（平均年龄：63.7岁，83%为女性）完成了KOOS-V、SF-36短表健康调查（SF-36）和数字疼痛评定量表（NPRS），其中67例在5-8天后重新评估。心理测量分析包括内部一致性、重测信度、结构效度和跨文化比较。结果skoos - v具有优良的内容效度（CVI = 0.86 ~ 1.00）、良好的内部一致性（Cronbach’s α = 0.70 ~ 0.98）和优良的重测信度（ICC = 0.77 ~ 0.90）。建构效度与SF-36身体功能（Spearman’s ρ = 0.66 ~ 0.82）和NPRS （ρ = - 0.49 ~ - 0.62）存在中至强相关性。跨文化比较表明，越南的kos量表与其他文化的kos量表存在同样的挑战。结论KOOS-V是评估越南患者KOA功能影响的可靠、有效的工具，有助于其在全球临床和研究环境中得到广泛应用。

期刊介绍： The Asia-Pacific Journal of Sports Medicine, Arthroscopy, Rehabilitation and Technology (AP-SMART) is the official peer-reviewed, open access journal of the Asia-Pacific Knee, Arthroscopy and Sports Medicine Society (APKASS) and the Japanese Orthopaedic Society of Knee, Arthroscopy and Sports Medicine (JOSKAS). It is published quarterly, in January, April, July and October, by Elsevier. The mission of AP-SMART is to inspire clinicians, practitioners, scientists and engineers to work towards a common goal to improve quality of life in the international community. The Journal publishes original research, reviews, editorials, perspectives, and letters to the Editor. Multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines will be the trend in the coming decades. AP-SMART provides a platform for the exchange of new clinical and scientific information in the most precise and expeditious way to achieve timely dissemination of information and cross-fertilization of ideas.
