The objective of the study was to cross-culturally adapt and assess the validity and reliability of the Turkish version of the CAIT (CAIT-TR).
The CAIT was translated and adapted into Turkish according to accepted cross-cultural adaptation guidelines of self-reported measures. A total of 130 individuals, including healthy participants (n = 40) and with chronic ankle instability (CAI) (n = 90), were recruited in this study. The internal consistency and test-retest reliability of the CAIT-TR were assessed using Cronbach's alpha and intraclass correlation coefficients (ICC), respectively. To assess convergent validity, hypotheses were tested regarding expected correlations between CAIT-TR, Foot and Ankle Outcome Score (FAOS) subscales, and the Visual Analogue Scale (VAS). Discriminative validity was evaluated with the hypothesis that the CAIT-TR can distinguish between subjects with and without CAI and also calculated a cut-off score for CAI. The dimensional structure of the CAIT-TR was investigated with confirmatory factor analysis. Additionally, minimal detectable change (MDC), floor/ceiling effects, and measurement error values were determined.
The CAIT-TR demonstrated high Internal consistency (Cronbach's alpha = 0.854) and test-retest reliability (ICC = 0.919). Regarding convergent validity, the CAIT-TR exhibited a moderate-strong correlation with both the FAOS and VAS. The confirmatory factor analysis supported the unidimensional structure of the questionnaire. The identified cut-off value for the CAIT-TR was 25, and the MDC for individual-level CAIT-TR scores was determined to be 1.87. No floor or ceiling effects were observed.
The CAIT-TR is a valid and reliable questionnaire for the assessment of ankle instability within the Turkish population.
本研究旨在对 CAIT（CAIT-TR）进行跨文化调适，并评估其在土耳其人群中的有效性和可靠性。
根据自我报告测量的公认跨文化调适指南，将 CAIT 翻译成土耳其语并进行调适。本研究共招募了 130 名个体，包括健康参与者（n=40）和慢性踝关节不稳定（CAI）患者（n=90）。使用 Cronbach's alpha 和组内相关系数（ICC）分别评估 CAIT-TR 的内部一致性和重测信度。为评估收敛效度，根据 CAIT-TR 与 Foot and Ankle Outcome Score（FAOS）分量表和视觉模拟量表（VAS）之间预期相关性的假设进行了测试。通过假设 CAIT-TR 可以区分有和无 CAI 的受试者，并计算 CAI 的截断值来评估判别效度。使用验证性因子分析研究了 CAIT-TR 的维度结构。此外，还确定了最小可检测变化（MDC）、地板/天花板效应和测量误差值。
CAIT-TR 表现出较高的内部一致性（Cronbach's alpha=0.854）和重测信度（ICC=0.919）。关于收敛效度，CAIT-TR 与 FAOS 和 VAS 均呈中度-强相关。验证性因子分析支持问卷的单维结构。确定 CAIT-TR 的截断值为 25，个体水平 CAIT-TR 得分的 MDC 为 1.87。未观察到地板或天花板效应。
CAIT-TR 是评估土耳其人群踝关节不稳定的有效且可靠的问卷。
