PURPOSE
To develop and psychometrically test a Brazilian-Portuguese version of the Cumberland Ankle Instability Tool (CAIT), the only questionnaire that provides a numeric measure for functional ankle instability.
METHODS
The CAIT was translated and adapted into Brazilian-Portuguese according to the Guidelines for the process of cross-cultural adaptation of self report measures. The Brazilian-Portuguese version of the CAIT was tested for internal consistency, test-retest reliability, ceiling and floor effects and responsiveness in 131 participants. Participants were recruited from the general community in Brazil (N = 101, community group) and from those seeking treatment for an ankle sprain from 2 clinics in Brazil (N = 30, treatment group).
RESULTS
The Brazilian-Portuguese version of the CAIT had high internal consistency (Cronbach alpha = 0.86 for right ankles and 0.88 for left ankles), reliability (ICC = 0.95, 95% CI 0.93-0.97); and good responsiveness (ES = 0.75, 95% CI 0.49-1.00). No ceiling or floor effects were observed.
CONCLUSIONS
The Brazilian-Portuguese version of the CAIT is as reliable as the English version of the questionnaire, has high internal consistency and good responsiveness. It thus provides the first tool that can be used to assess functional ankle instability by clinicians and researchers working among Brazilian-Portuguese speakers.
目的
开发并对坎伯兰踝关节不稳定工具（CAIT）的巴西葡萄牙语版本进行心理测量学测试，这是唯一一种能对功能性踝关节不稳定提供数值测量的问卷。
方法
根据自我报告测量跨文化适应过程指南，将CAIT翻译成巴西葡萄牙语并进行改编。对131名参与者测试了CAIT巴西葡萄牙语版本的内部一致性、重测信度、天花板效应和地板效应以及反应度。参与者从巴西普通社区招募（N = 101，社区组），以及从巴西2家诊所寻求踝关节扭伤治疗的患者中招募（N = 30，治疗组）。
结果
CAIT巴西葡萄牙语版本具有高内部一致性（右脚踝Cronbach α = 0.86，左脚踝为0.88）、信度（ICC = 0.95，95%CI 0.93 - 0.97）；以及良好的反应度（效应量 = 0.75，95%CI 0.49 - 1.00）。未观察到天花板效应或地板效应。
结论
CAIT巴西葡萄牙语版本与该问卷的英语版本一样可靠，具有高内部一致性和良好的反应度。因此，它为在讲巴西葡萄牙语的人群中工作的临床医生和研究人员提供了首个可用于评估功能性踝关节不稳定的工具。
