Note. CAPS = Clinician-Administered PTSD Scale; PSS = PTSD Symptom Scale; BDI = Beck Depression Inventory; PTSD = posttraumatic stress disorder.

^aPositive effect sizes indicate that participants in the CPT condition evidenced greater symptomatic improvement than participants in the MA condition.

^bPositive effect sizes indicate that participants in the PE condition evidenced greater symptomatic improvement than participants in the MA condition.

^cPositive effect sizes indicate that participants in the CPT condition evidenced greater symptomatic improvement than participants in the PE condition. Negative effect sizes indicate that participants in the PE condition evidenced greater symptomatic improvement than participants in the CPT condition.

^dMeasures of guilt were not assessed at 3 months posttreatment.
