RT Journal Article T1 Spanish Adaptation of the Inventory of Depression and Anxiety Symptoms (IDAS-II) and a study of its psychometric properties A1 Rosa Cáceres, Ana María A1 Stasik-O'Brien, Sara A1 Rojas, Antonio A1 Sánchez García, Manuel A1 Lozano Rojas, Óscar Martín A1 Díaz Batanero, María Carmen AB Background: The Inventory of Depression and Anxiety Symptoms (IDAS-II) is composed of 99 items organizedinto 18 specific scales that provides dimensional assessment of depression, anxiety and bipolar symptoms. Todate, IDAS-II is only available in the English and Turkish population. The main purpose of this study is to adaptthe 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 participantscompleted the Beck Depression Inventory-II, Beck Anxiety Inventory, Hypomania Check List-32, Post-traumaticStress Disorder Checklist-Civilian Version and Obsessive-Compulsive Inventory-Revised, in addition to theSpanish version of the IDAS-II.Results: The results indicate good internal consistency and high temporal stability of the Spanish version of theIDAS-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” accordingto the Hierarchical Taxonomy Of Psychopathology (HiTOP).Limitations: Study was conducted exclusively on student and community samples and some of the measures usedas gold-standard have presented limitationsConclusions: According to previous studies, the results supported the convergent and discriminant validity of themajority of IDAS-II scales. IDAS-II is useful in assessing the severity of depression, anxiety and bipolar symptomsin research contexts in a Spanish population according to the HiTOP model. However, more evidence is requiredto prove the adequate functioning of the IDAS-II in clinical samples.
