Many patients who seek treatment for chronic back pain are also at a higher risk of having comorbid anxiety- and depression-related disorders. Measures of mood and anxiety are routinely used in medical settings to screen for depression- and anxiety-related symptoms. However, factor analyses of other measures of mood and anxiety in medical settings often detect a somatization factor which, in turn, limits their discriminant validity for use across medical settings. The Inventory of Depression and Anxiety Symptoms-II (IDAS-II) is a comprehensive self-report inventory that assesses varying aspects of mood and anxiety. The purpose of this investigation is to examine the three-factor structure and validity of the IDAS-II in a chronic pain treatment-seeking sample. A total of 169 patients completed the IDAS-II and the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) upon admission. Confirmatory factor analyses were computed using the scales of the IDAS-II and zero-order correlations between the IDAS-II factors from the best-fitting model and scale scores of the MMPI-2-RF. Overall, a three-factor structure of the IDAS-II was not supported; instead, a one-factor solution fit best. Using the MMPI-2-RF as external criteria, the one-factor of the IDAS-II correlated highest with the Somatic Complaints scale and the Demoralization scale. Overall, item content on the IDAS-II shares overlap with many symptoms that patients with chronic pain likely would endorse. Discussion about implications of using mood/anxiety measures and models in medical settings that are in line with the Hierarchical Taxonomy of Psychopathology (HiTOP) are discussed.

许多寻求慢性背痛治疗的患者同时患焦虑和抑郁相关共病的风险也更高。在医疗环境中，情绪和焦虑测量通常用于筛查与抑郁和焦虑相关的症状。然而，对医疗环境中其他情绪和焦虑测量进行因素分析时，常常会检测到一个躯体化因素，这反过来又限制了它们在不同医疗环境中的判别效度。抑郁与焦虑症状量表第二版（IDAS-II）是一个全面的自我报告量表，用于评估情绪和焦虑的不同方面。本研究的目的是检验IDAS-II在寻求慢性疼痛治疗的样本中的三因素结构和效度。共有169名患者在入院时完成了IDAS-II和明尼苏达多相人格调查表第二版修订版（MMPI-2-RF）。使用IDAS-II的量表进行验证性因素分析，并计算最佳拟合模型中IDAS-II各因素与MMPI-2-RF量表分数之间的零阶相关性。总体而言，IDAS-II的三因素结构未得到支持；相反，单因素模型拟合最佳。以MMPI-2-RF作为外部标准，IDAS-II的单因素与躯体症状量表和士气低落量表的相关性最高。总体而言，IDAS-II上的项目内容与慢性疼痛患者可能认可的许多症状存在重叠。本文还讨论了在医疗环境中使用符合精神病理学层次分类法（HiTOP）的情绪/焦虑测量和模型的意义。（PsycInfo数据库记录（c）2022美国心理学会，保留所有权利）
