The aims of this study were to culturally translate and validate the Persian version of Tegner and Marx activity rating scales and to investigate their psychometric properties in a sample of patients (n = 100) with anterior cruciate ligament (ACL) injury.
Four questionnaires were completed by the respondents: Tegner and Marx activity scales, Knee injury and Osteoarthritis Outcome Score (KOOS) and Short-Form 12 Health Survey (SF-12). The Tegner and Marx were re-administered to 45 patients in the retest session, with time interval of 2-6 days between the two sessions. Test-retest reliability and internal consistency were assessed using intra-class correlation coefficient (ICC) and Cronbach's alpha, respectively. To evaluate construct validity of Tegner and Marx compared to similar and dissimilar concepts of KOOS and SF-12, the Spearman's rank correlation was used.
Both Tegner and Marx activity scales have a high ICC level. The minimum Cronbach's alpha level of 0.70 was exceeded by Marx scale. In terms of construct validity, most of a priori hypotheses were confirmed.
The Persian version of Tegner and Marx seems to be suitable for Iranian patients with ACL injury. Future studies are needed to investigate the psychometric properties of these questionnaires for Iranian patients with different knee problems.
本研究旨在对前交叉韧带（ACL）损伤患者群体进行文化调适及验证波斯语版 Tegner 和 Marx 活动评级量表，并探究其心理测量学特性。
受访者需填写 4 份问卷：Tegner 和 Marx 活动量表、膝关节损伤和骨关节炎结局评分（KOOS）以及简明健康调查量表 12 项（SF-12）。45 名患者参与重测，两次测试之间间隔 2-6 天。使用组内相关系数（ICC）和 Cronbach's alpha 评估重测信度和内部一致性。为评估 Tegner 和 Marx 与 KOOS 和 SF-12 相似和不同概念之间的结构有效性，采用 Spearman 秩相关分析。
Tegner 和 Marx 活动量表均具有较高的 ICC 水平。Marx 量表的 Cronbach's alpha 最小值为 0.70。在结构有效性方面，大多数先验假设得到证实。
波斯语版 Tegner 和 Marx 似乎适用于伊朗 ACL 损伤患者。未来需要对不同膝关节问题的伊朗患者进行这些问卷的心理测量学特性研究。
