在许多情况下，确定与焦虑相关的严重程度和损害是很重要的。我们开发了一个简短的（五项）连续测量，总体焦虑严重程度和损害量表（OASIS），它可以用于焦虑症，多重焦虑症和阈下焦虑症状。711名大学生完成了OASIS和额外的焦虑相关担忧和症状的自我报告评估。一个月后，一部分学生再次完成了几项测试。分样本分析的结果表明单因素结构，所有五个项目都有显著的负荷。OASIS具有良好的1个月重测信度、收敛效度和发散效度。OASIS值得考虑作为焦虑相关严重程度和损害的简短衡量标准，可用于焦虑症。
Establishing severity and impairment associated with anxiety is important in many settings. We developed a brief (five-item) continuous measure, the Overall Anxiety Severity and Impairment Scale (OASIS), which can be used across anxiety disorders, with multiple anxiety disorders, and with subthreshold anxiety symptoms. Seven hundred eleven college students completed the OASIS and additional self-report assessments of anxiety-related concerns and symptoms. A subset of students completed several measures again 1 month later. Results of a split-sample analysis suggested a single-factor structure, with all five items having salient loadings. The OASIS demonstrated excellent 1-month test-retest reliability, and convergent and divergent validity. The OASIS merits consideration as a brief measure of anxiety-related severity and impairment that can be used across anxiety disorders.
