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 焦虑严重程度测量：西班牙青年有效性和可靠性的证据。

背景 很少有关于 DSM-5 中提出的焦虑严重程度测量 (ASM) 的心理测量特性的研究，而且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版本的广场恐惧症、社交焦虑、分离焦虑、恐慌、广泛性焦虑和特定恐惧症严重程度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% 为女性）。我们进行了探索性和确认性因素分析以测试量表的结构、按性别划分的差异项目功能 (DIF)、Cronbach α 和序数 omega 以测试可靠性，以及 ASM 与不同结果之间的 Pearson 相关性，为收敛/区分（内化/外化症状）和标准有效性（满意度、生活质量和个性）提供证据。结果 结构分析支持所有 ASM 的单因素解决方案，除了特定恐惧症量表，这也是唯一显示 DIF 的量表。可靠性指数从 0.82 到 0.93 不等。所有六个量表都显示出与内化测量比外化测量更强的关联，并且与标准测量也呈负相关。结论 除了需要进一步检查的特定恐惧症量表外，西班牙语版的 ASM 适用于评估焦虑相关症状。结果 结构分析支持所有 ASM 的单因素解决方案，除了特定恐惧症量表，这也是唯一显示 DIF 的量表。可靠性指数从 0.82 到 0.93 不等。所有六个量表都显示出与内化测量比外化测量更强的关联，并且与标准测量也呈负相关。结论 除了需要进一步检查的特定恐惧症量表外，西班牙语版的 ASM 适用于评估焦虑相关症状。结果 结构分析支持所有 ASM 的单因素解决方案，除了特定恐惧症量表，这也是唯一显示 DIF 的量表。可靠性指数从 0.82 到 0.93 不等。所有六个量表都显示出与内化测量比外化测量更强的关联，并且与标准测量也呈负相关。结论 除了需要进一步检查的特定恐惧症量表外，西班牙语版的 ASM 适用于评估焦虑相关症状。
