Note. T1 = pre-treatment; CSR = clinician severity rating; treatment outcome = CSR at post-treatment – CSR at pre-treatment; SUDS = subjective units of distress; % steps = # of steps completed/# steps possible; IBI = change in interbeat interval from baseline to end of BAT; Δ SUDS = SUDS post – SUDS pre-treatment; Δ % Steps = % Steps post – % Steps pre-treatment; Δ IBI = IBI pre – Δ IBI post-treatment
