Abstract
CONTEXT
An easy-to-administer, function-based questionnaire to assess patients with various foot problems was required for a Greek-speaking population. This study aimed to translate and cross-culturally adapt the Quick Foot and Ankle Ability Measure (Quick-FAAM) into Greek and evaluate its reliability and validity.
DESIGN
Cross-sectional study.
METHODS
Established international guidelines for the cross-cultural adaptation of questionnaires were followed. The face and content validity of the Greek version of the Quick-FAAM (Quick-FAAM-GR), as well as the internal consistency and test-retest reliability upon repeated administration after 5 days, were examined. In addition, the construct validity of the scale was examined via exploratory factor analysis as well as by testing for associations with the Manchester Foot Pain and Disability Index, the 12-item Short-Form Survey (version 2), and a functional balance assessment test-the Y-Balance Test.
RESULTS
Sixty participants (18 women) with self-reported chronic ankle instability symptoms, with a median (interquartile range) age of 27 (7.7) years, participated in the study. Half of the participants were included in the test-retest reliability study. The Quick-FAAM-GR demonstrated face and content validity. Excellent internal consistency (Cronbach α = .961) and intrarater test-retest reliability (intraclass correlation coefficient ICC[2,1] = .93) were demonstrated, with a comparable error margin to the original version (standard error of the measurement = 2.1, 95% minimum detectable change = 5.9). Associations of the Quick-FAAM-GR scores to other questionnaires ranged from weak to strong (Spearman rho), all being statistically significant (Manchester Foot Pain and Disability Index from -.26, P = .04, to -.67, P < .001, and 12-item Short-Form Survey, version 2, between .41 and .72, P < .001), and to the Y-Balance Test between lower-limb differences (-.35 to -.58, P < .001). The exploratory factor analysis confirmed the single-factor structure of this scale. No floor/ceiling effects were observed.
CONCLUSIONS
The Greek Quick-FAAM has proven to be a valid and reliable tool for evaluating chronic ankle instability and can be used for clinical and research purposes in Greek-speaking individuals.
