Purpose of this study is to develop the Turkish version of Identification Functional Ankle Instability (IdFAI) scale in determined population, to evaluate the validity and reliability and to determine the level of ankle instability. A total of 100 cases (54 men, 46 women) were included to our study, they are 50 volleyball players between 18-38 years of age (28 male, 22 female) and 50 sedentary individual (26 males, 24 females). The construct validity, reference validity, sensitivity-specificity and test-retest reliability of Functional Ankle Instability Identification Scale which is a Turkish version of IdFAI was evaluated. For the test-retest reliability; the scale was applied to all cases again in 10-14 days. To evaluate the construct validity; factor analysis method was used. It was observed that the FABİT scale is grouped under 2 separate factors in itself. It was determined that the factor 1 variance is 46.68%, the factor 2 variance is 15.70% and the variance for FABİT scale is 62.38%. For reference validity; according to the sports physicians’ clinical diagnosis the instability of all individuals were evaluated and are compared with the scale total score. Pursuant thereto; it was found that there is a statistically significant relationship 0.738 ± 0.50 (95% CI: 0.640-0.835), p<0.0001 between the diagnosing physician and FABİT scale. The best cut-off point related to the total score of the scale with ROC analysis was determined as 10,5. Sensitivity and specificity values were calculated to evaluate the classification success of specified breakpoint and scale. Thus it was found that FABİT scale’s sensitivity is 0.611 and specificity is 0.804. Correlation with scale scores of test-retest results was examined with intraclass correlation coefficient (ICC). As a result, reliability of the scale FABİT was found to be 0.942 (95% CI: 0.915 to 0.961), p<0.0001. In accordance with these data; FABİT total scores were compared separately including genders, athletes and sedentary individuals, right and left side results between ones with ankle sprain and without ankle sprain. It hasn’t showed statistically significant differences between the sexes both for right side p=0.339 (95% CI) and left side p=0.635 (95% CI). Between sedentary individuals and volleyball athletes it was similar both for right side p = 0.697 (95% CI) and left side p = 0.114 (95% CI). Our study showed that IdFAI scale hasn’t been influenced by the gender and activity level variables of FABİT which is a Turkish version. It was found that there is a statistically significant difference in terms of sprain incident rate both for right side p=0.0001 (95% CI) and left side p=0.0001 (95% CI). The results obtained show that FABIT scale can accurately detect the relationship between the presence of sprain and instability and is supportive of the validity of the scale. Our study shows that FABIT scale is a simple, easy to apply, reliable, valid and selective scale to define functional ankle instability.
