The Inventory of Depression and Anxiety Symptoms (IDAS-II) is a self-report measure comprising 99 items divided into 18 non-overlapping scales that allows for a dimensional assessment of depression, anxiety, and bipolar symptoms. The IDAS-II is currently available in English, Turkish, Spanish, German, and Swedish. This study's major goal was to adapt and validate the IDAS-II to the Romanian population.
Participants from a community sample ( = 1,072) completed the IDAS-II (Romanian version) and additional measures assessing depression and anxiety disorders.
Item-level factor analyses validated the unidimensionality of the scales, and internal consistency results indicated that most symptom scales had satisfactory alpha coefficient values. Based on previous structural analyses, a confirmatory factor analysis (CFA) on the IDAS-II scales confirmed a three-component model of "Distress," "Obsessions/Fear," and "Positive Mood." Convergent and discriminant validity were established by correlational analyses with other symptom measures.
This study was conducted using a sample from the general population and several of the employed measures have limitations. Specifically, the current study was unable to employ Romanian versions of the gold-standard instruments that assess well-being, obsessive-compulsive disorder, and claustrophobia.
The IDAS-II (Romanian version) is the first clinical measure to assess internalizing dimensions of the Hierarchical Taxonomy of Psychopathology (HiTOP) model that is available for the Romanian population.
抑郁与焦虑症状量表（IDAS-II）是一种自我报告量表，包含99个项目，分为18个不重叠的分量表，可对抑郁、焦虑和双相情感症状进行维度评估。IDAS-II目前有英文、土耳其文、西班牙文、德文和瑞典文版本。本研究的主要目标是对IDAS-II进行改编并验证其在罗马尼亚人群中的有效性。
来自社区样本（n = 1072）的参与者完成了IDAS-II（罗马尼亚语版本）以及评估抑郁和焦虑障碍的其他量表。
项目层面的因素分析验证了各分量表的单维性，内部一致性结果表明大多数症状分量表具有令人满意的阿尔法系数值。基于先前的结构分析，对IDAS-II量表进行的验证性因素分析（CFA）证实了“痛苦”“强迫观念/恐惧”和“积极情绪”的三成分模型。通过与其他症状量表的相关分析建立了聚合效度和区分效度。
本研究使用的是来自普通人群的样本，并且所采用的一些量表存在局限性。具体而言，本研究无法使用罗马尼亚语版本的评估幸福感、强迫症和幽闭恐惧症的金标准工具。
IDAS-II（罗马尼亚语版本）是首个可用于罗马尼亚人群的评估精神病理学层次分类法（HiTOP）模型内化维度的临床量表。
