BACKGROUND Very few studies about the psychometric properties of the Anxiety Severity Measures (ASM) proposed in the DSM-5 exist, and none in Spanish-speaking populations. Thus, the aim of the present study was to provide validity and reliability evidence for the Spanish versions of the Agoraphobia, Social Anxiety, Separation Anxiety, Panic, Generalized Anxiety and Specific Phobia Severity measures. METHOD Participants included 567 Spaniards (mean age=21.26, SD=3.61; 68.3% women). We performed Exploratory and Confirmatory Factor Analyses to test the structure of the scales, Differential Item Functioning (DIF) by sex, Cronbach's alpha and ordinal omega to test reliability, and the Pearson correlations between the ASM and different outcomes to provide evidence for convergent/discriminant (internalizing/externalizing symptoms) and criterion validity (satisfaction, quality of life and personality). RESULTS Structural analyses supported a one-factor solution for all of the ASM except for the Specific Phobia scale, which was also the only scale that exhibited DIF. Reliability indices ranked from .82 to .93. All six scales showed stronger associations with internalizing than externalizing measures and were also negatively related to criterion measures. CONCLUSIONS The Spanish version of ASM is suitable for assessing anxiety-related symptoms, except the Specific Phobia Scale, which requires further examination.

自我报告的DSM-5焦虑严重程度测验：西班牙年轻人中有效性和可靠性的证据。

背景技术关于DSM-5中提出的焦虑严重程度测量（ASM）的心理计量学特性的研究很少，在讲西班牙语的人群中也没有。因此，本研究的目的是为西班牙恐惧症，社交焦虑症，分离性焦虑症，恐慌症，广泛性焦虑症和特殊恐惧症严重程度量表的西班牙语版本提供有效性和可靠性证据。方法参与者包括567名西班牙人（平均年龄= 21.26，SD = 3.61； 68.3％的女性）。我们进行了探索性和确认性因子分析，以测试量表的结构，性别差异项功能（DIF），克朗巴赫（Cronbach）α和序数ω来测试信度，以及ASM与不同结果之间的Pearson相关性，为趋同/区分（内在/外在症状）和标准有效性（满意度，生活质量和性格）提供证据。结果结构分析支持所有ASM的单因素解决方案，但比恐惧症量表（Special Phobia scale）除外，这也是唯一表现出DIF的量表。可靠性指数从.82到.93。所有六个量表均显示出与内部化的关联比与外部化的关联更强，并且也与标准化的衡量指标呈负相关。结论西班牙语版的ASM适用于评估与焦虑相关的症状，但特殊恐惧症量表除外，这需要进一步检查。结果结构分析支持所有ASM的单因素解决方案，但比恐惧症量表（Special Phobia scale）除外，这也是唯一表现出DIF的量表。可靠性指数从.82到.93。所有六个量表均显示出与内部化的关联比与外部化的关联更强，并且也与标准化的衡量指标呈负相关。结论西班牙语版的ASM适用于评估与焦虑相关的症状，除了需要进一步检查的特定恐惧症量表。结果结构分析支持所有ASM的单因素解决方案，但比恐惧症量表（Special Phobia scale）除外，这也是唯一表现出DIF的量表。可靠性指数从.82到.93。所有六个量表均显示出与内部化的关联比与外部化的关联更强，并且也与标准化的衡量指标呈负相关。结论西班牙语版的ASM适用于评估与焦虑相关的症状，但特殊恐惧症量表除外，这需要进一步检查。
