  1. Note. PDSS-SR = Panic Disorder Severity Scale-Self Report; BSQ1 = Body Sensation Questionnaire; ACQ = Agoraphobic Cognitions Questionnaire, total score; MI = Mobility Inventory, total score; SCL-90 = Symptom Check-List: Anx = anxiety; Pho = phobic anxiety; Dep = depression; MOS-SF-20 = Medical Outcomes Study Short-Form General Health Survey (SF-20): Mh = mental health.
  2. * based on n = 89 (the PDSS-SR and MASTERY were not used on the first 3 courses).
  3. ** Repeated Measures ANOVA, Simple Contrast p < 0.001.
