研究概览
简要总结
This trial is being completed to develop a stepped-care talk therapy model for patients with PTSD. Specifically, this study is testing whether beginning with one type of therapy is better than beginning with another type of therapy, and whether moving to a different therapy after four sessions is more helpful than staying with the same therapy, depending on how well it is working.
The central hypothesis is that beginning with a low- or medium-intensity PTSD intervention and then titrating intensity based on early indications of response will result in clinically significant PTSD symptom reduction with parsimony of resources.

研究组 & 干预措施
Prolonged Exposure for Primary Care (PE-PC) then continue as early responder
PE-PC consists of four weekly 30-minute sessions. At the 4th session or 9-week assessment point (whichever comes first), early responders will step down to every-other-week sessions for the duration of the second stage (for 8 weeks).
干预措施: Prolonged Exposure for Primary Care (PE-PC) (Behavioral)
Prolonged Exposure for Primary Care (PE-PC) then full PE
PE-PC consists of four weekly 30-minute sessions. At the 4th session or 9-week assessment point (whichever comes first), slow responders that are then randomized to full PE and will have sessions once a week for eight weeks. During these 60-minute sessions, participants will practice in vivo and imaginal exposure and continue these exposure exercises every day at home.

干预措施: Full Prolonged Exposure (Behavioral)
Clinician Supported PTSD Coach App then full PE
During the first stage of treatment, participants will receive four weekly clinician support sessions or 9 weeks (whichever occurs first), slow responders that are then randomized to full PE will have sessions once a week for eight weeks. During these 60 minute sessions, participants will practice in vivo and imaginal exposure and continue these exposure exercises every day at home.

Prolonged Exposure for Primary Care (PE-PC) then continued PE-PC
PE-PC consists of four weekly 30-minute sessions. At the 4th session or 9-week assessment point (whichever comes first), slow responders that are then randomized to continue with PE-PC (medium intensity) will continue weekly sessions for 8 weeks.
干预措施: Prolonged Exposure for Primary Care (PE-PC) (Behavioral)
Clinician Supported PTSD Coach App then continued CS PTSD Coach App
During the first stage of treatment, participants will receive four weekly clinician support sessions or 9 weeks (whichever occurs first), slow responders that are then randomized to continue this treatment will have the frequency reduced to twice monthly.
干预措施: Clinician Supported PTSD Coach App (Behavioral)
Clinician Supported (CS) PTSD Coach App then continue as early responder
During the first stage of treatment, participants will receive four weekly clinician support sessions or 9 weeks (whichever occurs first). Early responders will be encouraged to continue app use but will discontinue clinician support sessions for the remaining 8 weeks.

结局指标
主要结局
Change in PTSD symptoms as measured by the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 (CAPS-5)
时间窗: Baseline, 3-months
The CAPS-5 is a clinician-rated PTSD rating scale consisting of 30 items; the total score is calculated as the sum of 20 items assessing the 20 DSM-5 PTSD symptoms. These symptom items are scored on a 5-point scale from 0 (absent) to 4 (extreme/incapacitating). The total score of the 20 items ranges from 0 to 80 with higher scores indicating more severe PTSD symptoms. Therefore, a decrease in the total score indicates symptom improvement.
次要结局
- Change in depressive symptoms measured by the Patient Health Questionnaire (PHQ-9)(Baseline, 3-months)
- Change in quality of life and functioning measured by the EuroQol-5 Domain (EQ-5D-5L)(Baseline, 3-months)
- Change in PTSD symptoms by the PTSD Checklist (PCL-5)(Baseline, 3-months)
