Numbers represent group means (±SD), except for “n”, and “sex”, where number of subjects is presented. F = females, M = males; CRH = corticotropin releasing hormone; ASI = Anxiety Sensitivity Index. Trait Anxiety was measured using the Spielberger State-Trait Anxiety Scale. Stress was measured using a 10 point Likert scale of subjectively experienced stress in the prior week.
