The Inventory of Depression and Anxiety Symptoms (IDAS-II) is a self-report measure used to assess depression, anxiety, and bipolar symptoms. It consists of 99 items divided into 18 non-overlapping scales. The IDAS-II is available in English, Turkish, Spanish, German, and Swedish, and this study aimed to adapt and validate it for the Romanian population.
A total of 1,072 participants from a community sample completed the Romanian version of the IDAS-II, along with additional measures to assess depression and anxiety disorders. Item-level factor analyses confirmed that the scales were unidimensional, and most symptom scales showed satisfactory internal consistency (alpha coefficient values). Confirmatory factor analysis (CFA) supported a three-component model consisting of “Distress,” “Obsessions/Fear,” and “Positive Mood,” which was consistent with previous structural analyses. Correlational analyses with other symptom measures established convergent and discriminant validity.
It is important to note that this study had limitations, including the use of a sample from the general population and certain limitations associated with the employed measures.
