BACKGROUND
Anxiety disorders are frequent but remain often underdiagnosed and undertreated. Hence, valid screening instruments are needed to enhance the diagnostic process. The Clinical Anxiety Scale (CAS) is a 25-item anxiety screening tool derived from the Hamilton Anxiety Scale (HAM-A). However, this scale is not available in French. The General anxiety disorder - 7 (GAD-7) scale, which has been validated in French, is a 7-item instrument with good psychometric properties. This study contributes to the validation of an adapted French version of the CAS, using the GAD-7 as the reference.
METHODS
A forward-backward English-French-English translation of the CAS was performed according to standard practice. The French versions of the CAS and GAD-7 were completed by 127 French speaking healthcare professionals. CAS internal consistency was assessed using Crohnbach's alpha, and test-retest reliability was tested after 15 days in a subsample of 30 subjects. Convergent validity with GAD-7 was assessed using Pearson's correlation coefficient. Test-retest reliability was explored using one-way random effects model to calculate the intra-class correlation coefficient (ICC).
RESULTS
French CAS showed excellent internal consistency (Cronbach's alpha 0.97), high convergent validity with GAD-7 (Pearson's R 0.81, p < 0.001), and very good test-retest reliability (ICC = 0.97, 95% CI 0.93-0.98).
CONCLUSION
The proposed French version of the CAS showed high reliability and validity that need to be further investigated in different populations.
背景
焦虑障碍较为常见，但往往诊断不足和治疗不足。因此，需要有效的筛查工具来增强诊断过程。临床焦虑量表（CAS）是一种 25 项焦虑筛查工具，源自汉密尔顿焦虑量表（HAM-A）。然而，该量表没有法语版本。已经在法语中验证过的广泛性焦虑障碍 7 项量表（GAD-7）是一种具有良好心理测量特性的 7 项工具。本研究使用 GAD-7 作为参考，对经过适应性修改的法语版 CAS 进行了验证。
方法
按照标准程序对 CAS 进行了正向-反向英语-法语-英语翻译。127 名讲法语的医疗保健专业人员完成了 CAS 和 GAD-7 的法语版本。使用 Crohnbach 的α评估 CAS 的内部一致性，在 30 名受试者的子样本中经过 15 天后测试重测信度。使用 Pearson 相关系数评估与 GAD-7 的聚合效度。使用单向随机效应模型探索重测信度，以计算组内相关系数（ICC）。
结果
法语版 CAS 具有极好的内部一致性（Cronbach's alpha 0.97），与 GAD-7 具有高度的聚合效度（Pearson's R 0.81，p<0.001），并且重测信度非常好（ICC=0.97，95%CI 0.93-0.98）。
结论
所提出的法语版 CAS 具有较高的可靠性和有效性，需要在不同人群中进一步研究。
