Abstract
BACKGROUND
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.
METHODS
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.
RESULTS
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).
LIMITATIONS
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.
