The study aim was to cross-culturally adapt the Identification of Functional Ankle Instability (IdFAI) into a Spanish-language version (IdFAI-Sp), which would then be validated and its psychometric properties evaluated for use in possible cases of ankle instability.
The cross-cultural adaptation was performed following the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. Pearson correlations were calculated to assess the convergent validity between IdFAI and the Cumberland Ankle Instability Tool. Cronbach's alpha and test re-test reliability values were calculated and floor/ceiling effects analysed. Construct validity was assessed by confirmatory factor analysis (CFA).
The study population was composed of 110 participants, with a mean age of 40.49 years (10.43) and of whom 62 (56.36%) were female. Good test-retest results were obtained, with an intraclass correlation coefficient of 0.85 (ICC,: 95% CI: 0.82 - 0.88). The structure matrix was examined by CFA, which revealed a three-factor solution that accounted for 79.89% of the variance. The IdFAI-Sp obtained an excellent fit (RMSEA 0.068, GFI 0.94, CFI 0.98 and NFI 0.97).
This study validates the IdFAI-Sp questionnaire, corroborating its value to researchers and medical professionals as a self-reported outcomes measure for use with a Spanish-speaking population.IMPLICATIONS FOR REHABILITATIONThe Spanish-language version of the Identification of Functional Ankle Instability questionnaire (IdFAI-Sp) is a valid and reliable tool.The IdFAI-Sp enables researchers and healthcare professionals to identify and classify chronic ankle instability among Spanish-speaking patients.Accordingly, it can be considered a useful clinical instrument.Aapplication of the questionnaire before and after treatment can reveal the patient's degree of recovery over time.
本研究旨在将功能性踝关节不稳识别问卷（IdFAI）进行跨文化调适，形成西班牙语版（IdFAI-Sp），并对其进行验证，评估其在可能的踝关节不稳定病例中的心理测量学特性。
跨文化调适遵循国际药物经济学和结果研究学会的指南进行。计算 Pearson 相关系数以评估 IdFAI 与坎伯兰踝关节不稳定工具之间的收敛效度。计算克朗巴赫 α系数和重测信度值，并分析地板/天花板效应。通过验证性因子分析（CFA）评估结构效度。
研究人群由 110 名参与者组成，平均年龄为 40.49 岁（10.43），其中 62 名（56.36%）为女性。重测结果良好，组内相关系数为 0.85（ICC：95%CI：0.82-0.88）。通过 CFA 检验结构矩阵，得出三因素解，占方差的 79.89%。IdFAI-Sp 具有良好的拟合度（RMSEA 0.068，GFI 0.94，CFI 0.98 和 NFI 0.97）。
本研究验证了 IdFAI-Sp 问卷的有效性，为研究人员和医疗专业人员提供了一种西班牙语人群自我报告结局测量工具。
功能性踝关节不稳识别问卷西班牙语版（IdFAI-Sp）是一种有效且可靠的工具。IdFAI-Sp 使研究人员和医疗保健专业人员能够识别和分类西班牙语患者的慢性踝关节不稳定。因此，它可以被认为是一种有用的临床工具。在治疗前后应用问卷可以揭示患者随时间的恢复程度。
