This study translated and validated the Kujala scale, a well-documented questionnaire for patients with patellofemoral pain, into Chinese version.
Chinese Kujala scale was translated from the original English version following the recommendations of the International Society for Pharmacoeconomics and Outcomes Research. Sixty four Chinese reading patients who are diagnosed of patellofemoral pain were recruited from multiple hospitals and physiotherapy clinics. Psychometric property was evaluated in terms of test-retest reliability and internal consistency. Convergent validity was examined by Spearman rank correlation coefficient tests by comparing its score with the validated Chinese version of WOMAC Osteoarthritis Index and SF-36.
Chinese Kujala scale demonstrated excellent reliability (ICC = 0.968, p < 0.001). Cronbach's α of individual questions and its overall value were above 0.7. Strong correlation was found between the Chinese Kujala scale and the WOMAC Osteoarthritis Index (rho = -0.708, p < 0.001). Fairly weak correlations were also found between Chinese Kujala scale with the "physical" (rho = 0.413-0.498, p < 0.001) and "energy vitality" (rho = 0.290, p = 0.02) domains of SF-36. However, the relationship between the "bodily pain" was not significant (rho = 0.136, p = 0.284).
The Chinese translated version of Kujala scale is a reliable and valid instrument for assessing the patellofemoral pain associated functional disturbances among the patient cohort.
本研究将一种针对髌股疼痛患者的有充分文献记录的良好问卷——Kujala 量表翻译成中文版本，并对其进行验证。
根据国际药物经济学和结果研究学会的建议，将 Kujala 量表的中文版本从原始英文版本翻译而来。从多家医院和物理治疗诊所招募了 64 名被诊断为髌股疼痛的中文阅读患者。从测试-重测信度和内部一致性方面评估心理测量特性。通过 Spearman 等级相关系数检验，将其与经过验证的中文版 WOMAC 骨关节炎指数和 SF-36 进行比较，以评估其与膝关节骨关节炎指数和 SF-36 的相关性。
中文 Kujala 量表显示出良好的可靠性（ICC=0.968，p<0.001）。个体问题和总体的 Cronbach's α 值均高于 0.7。中文 Kujala 量表与 WOMAC 骨关节炎指数之间存在较强的相关性（rho=-0.708，p<0.001）。中文 Kujala 量表与 SF-36 的“生理”（rho=0.413-0.498，p<0.001）和“能量活力”（rho=0.290，p=0.02）领域之间也存在较弱的相关性。然而，“躯体疼痛”之间的关系不显著（rho=0.136，p=0.284）。
中文翻译的 Kujala 量表是一种可靠且有效的工具，可用于评估髌股疼痛患者相关的功能障碍。
