The Inventory of Depression and Anxiety Symptoms (IDAS-II) is composed of 99 items organized into 18 specific scales that provides dimensional assessment of depression, anxiety and bipolar symptoms. To date, IDAS-II is only available in the English and Turkish population. The main purpose of this study is to adapt the IDAS-II to the Spanish population and to assess the psychometric properties.
Participants included community adults (n = 620) and college students (n = 378). All participants completed the Beck Depression Inventory-II, Beck Anxiety Inventory, Hypomania Check List-32, Post-traumatic Stress Disorder Checklist-Civilian Version and Obsessive-Compulsive Inventory-Revised, in addition to the Spanish version of the IDAS-II.
The results indicate good internal consistency and high temporal stability of the Spanish version of the IDAS-II. Confirmatory factor analyses show for the first time that the three-factor structure of the IDAS-II (Distress, Obsessions/Fear, and Positive Mood) loads on a second order factor, labeled "Internalizing" according to the Hierarchical Taxonomy Of Psychopathology (HiTOP).
Study was conducted exclusively on student and community samples and some of the measures used as gold-standard have presented limitations CONCLUSIONS: According to previous studies, the results supported the convergent and discriminant validity of the majority of IDAS-II scales. IDAS-II is useful in assessing the severity of depression, anxiety and bipolar symptoms in research contexts in a Spanish population according to the HiTOP model. However, more evidence is required to prove the adequate functioning of the IDAS-II in clinical samples.
抑郁和焦虑症状量表（IDAS-II）由 99 个项目组成，分为 18 个特定量表，对抑郁、焦虑和双相情感障碍症状进行维度评估。迄今为止，IDAS-II 仅在英语和土耳其人群中可用。本研究的主要目的是将 IDAS-II 适应于西班牙语人群，并评估其心理测量特性。
参与者包括社区成年人（n=620）和大学生（n=378）。所有参与者完成了贝克抑郁量表-II、贝克焦虑量表、轻躁狂检查表-32、创伤后应激障碍检查表-平民版和强迫症量表修订版，以及 IDAS-II 的西班牙语版本。
结果表明，IDAS-II 的西班牙语版本具有良好的内部一致性和较高的时间稳定性。验证性因素分析首次表明，IDAS-II 的三因素结构（痛苦、强迫观念/恐惧和积极情绪）加载在第二个二阶因子上，根据精神病理学的分层分类法（HiTOP）命名为“内化”。
该研究仅在学生和社区样本中进行，并且一些用作金标准的测量方法存在局限性。
根据先前的研究，结果支持 IDAS-II 大多数量表的会聚和区分效度。根据 HiTOP 模型，IDAS-II 可用于在西班牙人群的研究背景下评估抑郁、焦虑和双相情感障碍症状的严重程度。然而，需要更多的证据来证明 IDAS-II 在临床样本中的适当功能。
