Brief Summary
For the first time panic disorder and agoraphobia are included as separate disorders in the DSM-5. Thus, agoraphobia no longer represents a subcategory of panic disorder. To diagnose both of the disorders, questionnaires are the method of choice. However, there are no measuring instruments available free of charge in German-speaking countries. In order to improve this situation, the Witten Panic Disorder Questionnaire (WPF) and the Witten Agoraphobia Questionnaire (WAF) are constructed in accordance with the DSM-5 criteria. Both measuring instruments are included as a part of a ten instrument battery. WAF and WPF will be delivered to a patient sample of patients with panic disorder and/or agoraphobia as well as depressed patients (discriminant validity). Factor analyzes and item analyses will be conducted.
