Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether 60-minute sessions of prolonged exposure (PE) are as effective as the standard 90-minute session for treating posttraumatic stress disorder (PTSD). Participants will include patients ages 18 or older with a current diagnosis of PTSD who are seeking treatment in our clinic. Patients who have current substance dependence, psychosis, and suicidal ideation with intent and plan may not be suitable for receiving PE and may be offered another treatment or referred to a different treatment center. Participants will be randomized to receive either the 90- minute or 60-minute PE session. A blind evaluator will assess for pre-treatment, post-treatment, and follow-up levels of symptom severity using the PTSD Symptoms Scale Interview (PSS-I). Participants will attend weekly treatment sessions with any of our faculty members and will complete self-report measures at every session (see below).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

90 minute Prolonged Exposure Sessions

Prolonged Exposure Therapy for PTSD consists of 10 to 15 weekly or twice-weekly sessions, each lasting about 90 minutes, with 40 to 60 minutes imaginal exposure.

Group Type ACTIVE_COMPARATOR

Prolonged Exposure Therapy

Intervention Type BEHAVIORAL

Prolonged exposure therapy (PE), a specific exposure therapy program for PTSD is a highly effective treatment for PTSD. The key components of PE are imaginal exposure to the traumatic event and processing it (revisiting of the traumatic memory in imagination) followed by processing of the revisiting experience, and in vivo exposure to avoided trauma-related situations and objects.

60 minute Prolonged Exposure Sessions

This treatment condition is a modified version of Prolonged Exposure therapy for PTSD. It consists of 10 to 15 weekly or twice-weekly sessions, each lasting about 60 minutes, with 20 minutes imaginal exposure.

Group Type EXPERIMENTAL

Prolonged Exposure Therapy

Intervention Type BEHAVIORAL
