Note. N = 12. To obtain a headache and an orthostatic panic score, for the first assessment, we totaled and then averaged the panic attack severity scale score for Weeks 4 and 6; for the second assessment, Weeks 18 and 20; and for the third assessment Weeks 34 and 36. HTQ = Harvard Trauma Questionnaire; ASI = Anxiety Sensitivity Index; HSCL = Hopkins Symptom Checklist; HPASS = Headache Panic Attack Severity Scale; OPASS = Orthostatic Panic Attack Severity Scale.
