Abstract

Purpose: The aim of this study was to develop a Polish version of the Cumberland Ankle Instability Tool (CAIT-PL) questionnaire and perform CAIT-PL cultural adaptation with assessment of its psychometric properties.Methods: The original CAIT was translated into the Polish language using standard guidelines. The CAIT-PL was completed on 2 occasions by 105 participants both with and without a history of ankle sprains. Psychometric evaluation of CAIT-PL included an assessment of internal consistency, test-retest reliability, standard error of measurement, convergent and construct validity.Results: The CAIT-PL was successfully translated and adapted into Polish culture with satisfactory internal consistency (Cronbach's α = 0.83) and adequate test-retest reliability resulting in ICC_2,1 = 0.89 (95% CI: 0.84-0.92). Measurement error was low (SEM = 0.76 and MDC = 2.10). Convergent validity of the CAIT-PL ranged from weak to strong using Spearman's correlation coefficient between CAIT-PL and FAOS subscales (r = 0.39-0.67; p < 0.05). Construct validity was confirmed.Conclusion: The Polish version of the Cumberland Ankle Instability Tool is a valid and reliable questionnaire for assessment of functional ankle instability among the Polish population.

Plain language summary

The Cumberland Ankle Instability Tool is broadly used to assess functional ankle instability and its severity.The Polish version of Cumberland Ankle Instability Tool (CAIT-PL) showed adequate psychometric properties.The CAIT-PL is ready to be used in clinical practice and for research applications in Polish-speaking population.
