This study examined the validity and reliability of the Korean version of the Generalized Anxiety Disorder-7 (GAD-7) scale. The GAD-7 was standardized with data from 112 patients at a psychiatric outpatient clinic. The GAD-7 revealed high internal consistency, good test-retest reliability, and convergent validity. The ROC analysis resulted in poor sensitivity and specificity for detecting anxiety disorders in a psychiatric setting. The GAD-7 may not be useful in diagnosing anxiety disorders in a psychiatric setting, even though it appears to be a reliable, efficient, and valid measurement tool for evaluating anxiety symptoms.
本研究旨在检验韩文版广泛性焦虑障碍量表（GAD-7）的效度和信度。该量表以精神科门诊 112 名患者的数据为基础进行标准化。研究结果表明，GAD-7 具有较高的内部一致性、良好的重测信度和聚合效度。但在精神科环境中，GAD-7 对焦虑障碍的诊断效能较低，ROC 分析显示其灵敏度和特异性均不佳。因此，GAD-7 可能不是一种在精神科环境中诊断焦虑障碍的有效工具，但它似乎是一种可靠、高效且有效的焦虑症状评估工具。
