Equivalence of online and paper administration of Identification of Functional Ankle Instability (IdFAI) scale

Abstract

Purpose: Online use of questionnaires offers many advantages over paper version such as easier participant access, lower cost, faster completion and efficient data management. Thus, it is important to collect valid and reliable data remotely in clinical care and research in order to decrease the patient and participant burden and cost of data collection. The primary aim was to develop online administration of Identification of Functional Ankle Instability (IdFAI) scale in both English and Turkish versions. Secondary aim was to test validity and reliability of the online version of IdFAI scale in both languages. Methods: Turkish and English versions of the IdFAI scale were used with both paper and online administration. Validity of the questionnaire administration methods (paper vs online) were analysed with Cohen’s d effect sizes. Additionally, limits of agreement with Bland and Altman plots and modality (questionnaire administration) order effect were analysed with t-tests. Test-retest reliability of the online versions were analysed using the Intraclass Correlation Coefficient. Results: 60 participants equally distributed between those who speak English (30.3±5.8 years, 16 females, 24.0±3.4 kg/m2) and Turkish (27.4±7.7 years, 17 females, 23.3±3.9 kg/m2) were recruited. There was no systematic difference between administration methods for the IdFAI scale in both language (English; d=0.13, Turkish; d=0.12) without any order effect (all p>0.05). Test-retest reliability was excellent for both online versions (English; ICC=0.96, Turkish; ICC=0.98). Conclusion: The online versions of the IdFAI scale in both English and Turkish were valid and reliable, therefore being suitable for clinical and research purposes.
