Abstract

The study examined psychometric properties of the Turkish version of the Inventory of Depression and Anxiety Symptoms-II (IDAS-II) in a Turkish sample. The sample consisted of nonclinical (N = 931) and clinical (N = 208) individuals. Confirmatory factor analysis showed that Turkish IDAS-II was similar to the original IDAS-II and supported the construct validity of the test. The Turkish IDAS-II showed good internal consistency, significant acceptable retest correlations, and was sensitive to changes over time. The Turkish IDAS-II also showed good convergent and discriminant validity in relation to the Beck Depression Inventory, the Beck Anxiety Inventory, the Mood Disorder Questionnaire, the Maudsley Obsessive Compulsive Inventory, the Panic Agoraphobia Scale, and the Post-Traumatic Stress Disorder Checklist-Civilian Version. Discriminant analyses revealed that the subscales of the Turkish IDAS-II significantly differentiated healthy controls from outpatients. The Turkish IDAS-II is a reliable and valid measure for assessing symptoms of depression and anxiety in Turkish-speaking participants.
