Tests and scales measuring psychological disorders should provide information about how scores relate to other constructs such as quality of life or functional impairment. Such information is necessary to allow that their scores contribute to clinical decision making. The current study analyzes the clinical utility of the Spanish version of the Inventory for Depression and Anxiety Symptoms (IDAS-II) to discriminate between different levels of functional impairment and identify the IDAS-II scales that contribute most to explaining impairment. The total sample ( = 1390) consists of two subsamples: a community sample of the general population ( = 1072) selected by random sampling; and a sample of patients ( = 318) from public and private mental health services. The Spanish IDAS-II for measuring internalizing symptoms and WHODAS 2.0 for measuring impairment were administered to all participants. All scales show statistically significant higher scores in the patient sample, with Cohen's effect sizes values greater than 0.30, except for well-being ( = 0.19). The cutoff values and their confidence intervals do not overlap with the means of either the community or patient sample. AUC values for most of the scales are above .70, except for appetite gain, ordering, euphoria, cleaning, and well-being. Multiple linear regression model using IDAS-II scales explain 57.1% of the variance of the WHODAS 2.0 ( = 155.305; < .001). Cutoff values provided allow us to reliably differentiate between the patients and community samples. Spanish IDAS-II scores show greater sensitivity and specificity in detecting those with greater impairment. General Depression, Lassitude, Panic and Claustrophobia contribute to impairment in a greater extent. Knowledge of which symptoms are most related with impairment, allows healthcare providers to improve treatment planning based on empirical evidence.
测量心理障碍的测试和量表应提供有关分数如何与其他结构（如生活质量或功能损害）相关的信息。此类信息对于使它们的分数有助于临床决策是必要的。当前研究分析了西班牙语版抑郁与焦虑症状量表（IDAS-II）在区分不同程度功能损害以及识别对解释损害贡献最大的IDAS-II量表方面的临床效用。总样本（n = 1390）由两个子样本组成：通过随机抽样选取的普通人群社区样本（n = 1072）；以及来自公共和私人心理健康服务机构的患者样本（n = 318）。向所有参与者施测用于测量内化症状的西班牙语IDAS-II和用于测量损害的世界卫生组织残疾评定量表2.0（WHODAS 2.0）。除幸福感（d = 0.19）外，所有量表在患者样本中的得分在统计学上均显著更高，科恩效应量值大于0.30。临界值及其置信区间与社区或患者样本的均值均不重叠。除食欲增加、秩序、欣快感、清洁和幸福感外，大多数量表的AUC值均高于0.70。使用IDAS-II量表的多元线性回归模型解释了WHODAS 2.0变异的57.1%（F = 155.305；p <.001）。提供的临界值使我们能够可靠地区分患者和社区样本。西班牙语IDAS-II分数在检测损害程度较大的患者时显示出更高的敏感性和特异性。一般抑郁、倦怠、惊恐和幽闭恐惧症对损害的贡献更大。了解哪些症状与损害最相关，有助于医疗保健提供者根据实证证据改进治疗计划。
