An observational study in Panic Disorder, Panic Disorder With Agoraphobia and Agoraphobia, sponsored by Ulrike Willutzki. Status unknown at 1 site in Germany. Per ClinicalTrials.gov, last updated 2019-03-21.
Sponsored by Ulrike Willutzki · Observational
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 Thus, agoraphobia no longer represents a subcategory of panic disorder.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.
270 studies on the registry are indexed under Panic Disorder; 37 are open to participants now.
This study's planned enrollment of 500 is above the median of 200 across 50 observational studies indexed under Panic Disorder.

Wittener Panik Fragebogen (WPF)
Self developed panic disorder questionnaire. Measures panic symptoms on one scale. Items are averaged. Range: 1-5. Higher values represent a worse outcome.
Time frame: 5 min
WAF
Self developed agoraphobia questionnaire. Measures agoraphobia symptoms on two scales (Fear and Avoidance). Items are averaged to calculate the subscales. Range: 1-5 (Fear); 1-3 (Avoidance). Higher values represent a worse outcome.
Time frame: 10 min
Agoraphobic Cognition Questionnaire (ACQ)
Chambless et al. (1985); Ehlers et al. (1993). The questionnaire measures anxious thoughts on two scales: Loss of Control and Physical Concerns. Items are averaged to calculate the subscales. Range: 1-5. A total score is calculated by averaging all items. Higher values represent a worse outcome.
Time frame: 5 min
Body Sensations Questionnaire (BSQ)
Chambless et al. (1985); Ehlers et al. (1993). The questionnaire measures body sensations that may occur in a feared situation. Items are averaged to calculate a total score. Range: 1-5. Higher values represent a worse outcome.
Time frame: 5 min
Mobility Inventory (MI)
Chambless et al. (1985); Ehlers et al. (1993). The questionnaire measures avoidance of agoraphobic situations on two scales (Avoidance Alone and Avoidance Accompanied). Items are averaged to calculate the scales. Range: 1-5. Higher values represent a worse outcome.
Time frame: 10 min
Agoraphobic Self-Statements Questionnaire (ASQ)
Hout et al. (2001). Measures agoraphobic statements on two scales (positive self-statements and negative self-statements). Items are averaged. Range: 0-4. Higher values represent a better outcome on the positive scale and a worse outcome on the negative scale.
Time frame: 5 min
Agoraphobic Cognitions Scale - extended version (ACS+)
Hoffart et al. (1992). Measures fearful cognitions on three scales (fear of bodily incapacitation, fear of losing control, and fear of acting embarrassingly). Items are averaged to calculate the scales. Range: 0-4. Higher values represent a worse outcome.
Time frame: 5 min
Patient Health Questionnaire - D (PHQ-D) - Subscale Panic Syndrome
Spitzer, Kroenke \& Williams (1999); Löwe et al. (2002). The questionnaire measures symptoms on modular scales. The panic syndrome subscale is calculated by summing up all 11 items. The scale ranges from 0 to 1. The sum score ranges from 0 to 11. Higher values represent a worse outcome.
Time frame: 5 min

Derogatis \& Melisaratos (1983); Franke (2000). Measures psychopathological symptoms on nine scales (Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic Anxiety, Paranoid Ideation, Psychoticism). Items are averaged to calculate the subscale scores. Range: 0-4. The Global Severity Index (GSI) is calculated by averaging all items. Higher values represent a worse outcome.
Time frame: 10 min
Beck Depression Inventory (BDI)
Beck et al. (1961). Measures depressive symptoms on one scale. Items summed up to calculate the toal score. The scale ranges from 0 to 3. The sum score ranges from 0 to 63. Higher values represent a worse outcome.
Time frame: 10 min
