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. METHOD: 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. RESULTS: 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. CONCLUSIONS: 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.
