Procedures
Treatment was provided by study therapists (T.H.B., B.A.F., W.R.E., S.S., B.N.H.-C., H.H., V.M.J., C.L.S., D.S., L.M.K., and K.M.G.) with at least a master’s degree in clinical psychology or social work and who had extensive training in PE. Protocol adherence was assessed during weekly study team meetings. Participants completed assessments during treatment (following treatment days 5, 10, and 14) and at 1, 3, and 6 months after treatment. All assessments were administered by master’s- or doctoral-level independent evaluators who were blinded to treatment condition.
