Abstract
The present study was planned to translate and culturally adapt the Olerud-Molander
Ankle Score (OMAS) and assess the validity and reliability of the Turkish translation
of the OMAS in patients with surgically treated malleolar fracture. The OMAS was adapted
for use in Turkish by first translating it and then back-translating it in accordance
with published guidelines. The final Turkish version of the OMAS was administered
to 91 patients participating in the present study. The OMAS questionnaire was repeated
7 days later to assess test–retest reliability. Spearman's rank correlation analysis
was used for each question’s score and the total score, and the intraclass correlation
coefficient was calculated for test–retest reliability. The internal consistency of
the OMAS-TR was assessed using Cronbach's α. Concurrent validity was evaluated by
comparing the OMAS with the Foot and Ankle Outcome Score and global self-rating function
(GSRF). The GSRF has 5 options: very good, good, fair, poor, and very poor. These
are assessed using a 5-point Likert scale. Before validity analysis, the GSRF score
was reduced to 3 groups. In the test–retest reliability assessment, the OMAS showed
high correlation (r = 0.882). The intraclass correlation coefficient was 0.942. Cronbach's α was 0.762
and 0.731 at days 1 and 7 (adequate internal consistency). The correlation coefficients
versus the 5 subscales of the Foot and Ankle Outcome Score ranged from r = 0.753 to r = 0.809 (p = .000) and versus the GSRF was r = −0.794 (p = .000). According to results of the present study, the Turkish version of the OMAS
demonstrated adequate test–retest reliability, excellent internal consistency, and
evidence of validity for Turkish-speaking patients treated surgically for ankle fracture.

- Validity and Reliability of Turkish Version of Olerud-Molander Ankle Score in Patients With Malleolar Fracture by Büker et alThe Journal of Foot and Ankle SurgeryVol. 58Issue 2
- PreviewWe read the recently reported study by Büker et al (1) with great interest, because we had already reported “Translation, cross-cultural adaptation, reliability and validity of the Turkish version of the Olerud-Molander Ankle Score (OMAS)” just 6 months previously (2). First, if the Turkish version is already available and reported, it is not necessary to translate and culturally adapted the same outcome score again. In such a situation, if the authors had already started the study but were too late to report it before our study, they could have used our Turkish version for a different patient population to determine whether it was reliable and valid.
