广泛性焦虑症（GAD）是一种普遍存在的心理健康状况，但在全世界范围内都被低估了。这项研究将 7 项自填式 GAD-7 量表进行了西班牙语文化适应，该量表用于识别可能患有 GAD 的患者。改编是由专家小组使用概念等效过程进行的，包括一式两份的向前和向后翻译。内容有效性通过参与者间协议进行评估。使用ROC曲线分析探讨标准有效性，并确定不同截断值的敏感性、特异性、预测阳性值和阴性值。还使用 HAM-A、HADS 和 WHO-DAS-II 量表探讨了同时有效性。研究样本由 212 名受试者（106 名 GAD 患者）组成，平均年龄为 50.38 岁（SD = 16.76）。平均完成时间为 2 分 30 秒。量表中没有任何项目留空。地板和天花板的影响可以忽略不计。无需协助广泛性焦虑症患者填写调查问卷。通过因子分析，该量表显示为一维（解释方差 = 72%）。截止点 10 显示足够的敏感性 (86.8%) 和特异性 (93.4%)，AUC 具有统计显着性 [AUC = 0.957-0.985]； p < 0.001]。该量表与 HAM-A（0.852，p < 0.001）、HADS（焦虑域，0.903，p < 0.001）和 WHO-DAS II（0.696，p > 0.001）显着相关。老年人，尤其是那些年纪很大的人，可能需要一些帮助来完成量表。经过文化适应过程后，获得了西班牙语版本的 GAD-7 量表。其内容的有效性以及项目在西班牙文化背景下的相关性和充分性得到了确认。
Generalized anxiety disorder (GAD) is a prevalent mental health condition which is underestimated worldwide. This study carried out the cultural adaptation into Spanish of the 7-item self-administered GAD-7 scale, which is used to identify probable patients with GAD. The adaptation was performed by an expert panel using a conceptual equivalence process, including forward and backward translations in duplicate. Content validity was assessed by interrater agreement. Criteria validity was explored using ROC curve analysis, and sensitivity, specificity, predictive positive value and negative value for different cut-off values were determined. Concurrent validity was also explored using the HAM-A, HADS, and WHO-DAS-II scales. The study sample consisted of 212 subjects (106 patients with GAD) with a mean age of 50.38 years (SD = 16.76). Average completion time was 2'30''. No items of the scale were left blank. Floor and ceiling effects were negligible. No patients with GAD had to be assisted to fill in the questionnaire. The scale was shown to be one-dimensional through factor analysis (explained variance = 72%). A cut-off point of 10 showed adequate values of sensitivity (86.8%) and specificity (93.4%), with AUC being statistically significant [AUC = 0.957-0.985); p < 0.001]. The scale significantly correlated with HAM-A (0.852, p < 0.001), HADS (anxiety domain, 0.903, p < 0.001), and WHO-DAS II (0.696, p > 0.001). Elderly people, particularly those very old, may need some help to complete the scale. After the cultural adaptation process, a Spanish version of the GAD-7 scale was obtained. The validity of its content and the relevance and adequacy of items in the Spanish cultural context were confirmed.
