Chronic hip joint disease has a high prevalence in China, and the primary scale currently used to assess functional recovery after total hip arthroplasty (THA) is the Hip disability and Osteoarthritis Outcome Score - Physical Function Short-form (HOOS-PS). Therefore, our objective was to translate the HOOS-PS scale into Simplified Chinese and evaluate its reliability, validity, and responsiveness in THA patients.
First, we followed the widely accepted cross-cultural translation process to translate the original HOOS-PS into the Chinese version of HOOS-PS (CHOOS-PS). Then, we recruited patients with chronic hip joint disease who were scheduled to undergo THA to complete the Western Ontario and McMaster Universities Arthritis Index (WOMAC), the Oxford Hip Score (OHS), Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and CHOOS-PS scales. Subsequently, we calculated the standardized response mean (SRM), effect size (ES), Spearman correlation coefficient (), standard error of measurement (SEM), intraclass correlation coefficient (ICC), Cronbach’s alpha coefficient, and confirmatory factor analysis (CFA) based on the scale scores.
Ultimately, 142, 138, and 109 patients completed the scale assessments at three stages. The results showed that CHOOS-PS has excellent test-retest reliability (ICC = 0.848–0.919) and good internal consistency (Cronbach’s alpha = 0.892). The CHOOS-PS questionnaire demonstrated excellent correlation with the OHS scale ( = 0.874), good correlation with all three subscales of the WOMAC ( = 0.638–0.764), moderate to good correlation with the physical dimensions of the SF-36 ( = 0.424–0.693), and poor to fair correlation with the mental dimensions of the SF-36 ( = 0.165–0.319). The CFA results showed a good fit (root mean square error of approximation (RMSEA) = 0.050, the comparative fit index (CFI) = 0.995, and the Tucher-Lewis Index (TLI) value = 0.991). These results indicate that the HOOS-PS scale has good construct validity. Additionally, CHOOS-PS showed good responsiveness (ES = 1.93, SRM = 1.88).
The CHOOS-PS scale is a reliable tool for evaluating the functional outcomes of Chinese patients with chronic hip joint disease after THA.
慢性髋关节疾病在中国的患病率较高，目前用于评估全髋关节置换术（THA）后功能恢复的主要量表是髋关节功能障碍与骨关节炎疗效评分-身体功能简表（HOOS-PS）。因此，我们的目的是将HOOS-PS量表翻译成简体中文，并评估其在THA患者中的信度、效度和反应度。
首先，我们遵循广泛接受的跨文化翻译流程，将原始的HOOS-PS翻译成中文版的HOOS-PS（CHOOS-PS）。然后，我们招募计划接受THA的慢性髋关节疾病患者，以完成西安大略和麦克马斯特大学骨关节炎指数（WOMAC）、牛津髋关节评分（OHS）、医学结局研究36项简短健康调查（SF-36）和CHOOS-PS量表。随后，我们根据量表得分计算标准化反应均值（SRM）、效应量（ES）、斯皮尔曼相关系数（）、测量标准误差（SEM）、组内相关系数（ICC）、克朗巴赫α系数和验证性因素分析（CFA）。
最终，142例、138例和109例患者在三个阶段完成了量表评估。结果表明，CHOOS-PS具有出色的重测信度（ICC = 0.848 - 0.919）和良好的内部一致性（克朗巴赫α = 0.892）。CHOOS-PS问卷与OHS量表具有出色的相关性（ = 0.874），与WOMAC的所有三个子量表具有良好的相关性（ = 0.638 - 0.764），与SF-36的身体维度具有中度至良好的相关性（ = 0.424 - 0.693），与SF-36的心理维度具有较差至中等的相关性（ = 0.165 - 0.319）。CFA结果显示拟合良好（近似均方根误差（RMSEA） = 0.050，比较拟合指数（CFI） = 0.995，Tucher-Lewis指数（TLI）值 = 0.991）。这些结果表明HOOS-PS量表具有良好的结构效度。此外，CHOOS-PS显示出良好的反应度（ES = 1.93，SRM = 1.88）。
CHOOS-PS量表是评估中国慢性髋关节疾病患者THA后功能结局的可靠工具。
