Evaluation of the psychometric properties of a translated, culturally adapted questionnaire.
Translating, culturally adapting, and validating the Italian version of the Cumberland Ankle Instability Tool (CAIT-I).
Ankle sprains are one of the most common musculoskeletal injuries and can lead to chronic ankle instability (CAI). The International Ankle Consortium recommends the Cumberland Ankle Instability Tool (CAIT) as a valid and reliable self-report questionnaire assessing the presence and severity of CAI. At this moment, there is no validated Italian version of CAIT.
The Italian version of the CAIT (CAIT-I) was developed by an expert committee. Test-retest reliability of the CAIT-I was measured in 286 healthy and injured participants within a 4-9-day period, by using Intraclass Correlation Coefficients (ICC). Construct validity, exploratory factor analysis, internal consistency and sensitivity were examined in a sample of 548 adults. Instrument responsiveness over 4 time points was determined in a subgroup of 37 participants.
The CAIT-I demonstrated excellent test-retest reliability (ICC≥0.92) and good internal consistency (α = .84). Construct validity was confirmed. Identified cut-off for the presence of CAI was 24.75, with sensitivity= 0.77 and specificity= 0.65. There were significant differences across time for CAIT-I scores (P < .001), demonstrating responsiveness to change, but no floor or ceiling effects.
The CAIT-I demonstrates acceptable psychometric performance as a screening and outcome measure. The CAIT-I is a useful tool to assess the presence and severity of CAI.
评价经过翻译和文化调适的问卷的心理计量学特性。
翻译、文化调适并验证意大利版坎伯兰踝关节不稳定性工具（CAIT-I）。
踝关节扭伤是最常见的肌肉骨骼损伤之一，可导致慢性踝关节不稳定（CAI）。国际踝关节联合会建议使用坎伯兰踝关节不稳定性工具（CAIT）作为一种有效的、可靠的自评问卷，评估 CAI 的存在和严重程度。目前，尚无经过验证的 CAIT 意大利语版本。
由一个专家委员会制定了 CAIT-I 的意大利语版本。通过使用组内相关系数（ICC），在 4-9 天的时间内对 286 名健康和受伤参与者进行了 CAIT-I 的测试-重测信度测量。在 548 名成年人的样本中，对结构有效性、探索性因素分析、内部一致性和敏感性进行了检验。在 37 名参与者的亚组中，确定了 4 个时间点的仪器反应能力。
CAIT-I 显示出极好的测试-重测信度（ICC≥0.92）和良好的内部一致性（α=0.84）。结构有效性得到确认。确定 CAI 存在的临界值为 24.75，敏感性=0.77，特异性=0.65。CAIT-I 评分在不同时间点有显著差异（P<0.001），表明对变化有反应能力，但没有地板或天花板效应。
CAIT-I 在作为筛选和结果测量工具方面具有可接受的心理计量学性能。CAIT-I 是评估 CAI 存在和严重程度的有用工具。
