NCT05457985

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in PTSD symptoms as measured by the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 (CAPS-5)

    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.

    Baseline, 3-months

Secondary Outcomes (3)

  • Change in PTSD symptoms by the PTSD Checklist (PCL-5)

    Baseline, 3-months

  • 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

Study Arms (6)

Prolonged Exposure for Primary Care (PE-PC) then continue as early responder

EXPERIMENTAL

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).

Behavioral: Prolonged Exposure for Primary Care (PE-PC)

Clinician Supported (CS) PTSD Coach App then continue as early responder

EXPERIMENTAL

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.

Behavioral: Clinician Supported PTSD Coach App

Prolonged Exposure for Primary Care (PE-PC) then full PE

EXPERIMENTAL

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.

Behavioral: Prolonged Exposure for Primary Care (PE-PC)Behavioral: Full Prolonged Exposure

Clinician Supported PTSD Coach App then full PE

EXPERIMENTAL

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.

Behavioral: Full Prolonged ExposureBehavioral: Clinician Supported PTSD Coach App

Prolonged Exposure for Primary Care (PE-PC) then continued PE-PC

EXPERIMENTAL

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.

Behavioral: Prolonged Exposure for Primary Care (PE-PC)

Clinician Supported PTSD Coach App then continued CS PTSD Coach App

EXPERIMENTAL

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.

Behavioral: Clinician Supported PTSD Coach App

Interventions

Treatment follows the standardized PE-PC manual and workbook.PE-PC consists of four weekly 30-minute sessions. In vivo and imaginal exposure are introduced at the first session and reviewed at Sessions 2-4. To conduct in vivo exposure, participants repeatedly and systematically approach objectively safe people, places, objects, and situations that they avoid because these stimuli remind them of their trauma. 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.

Treatment will follow the standardized PE manual. Participants will have 60 minute sessions once a week for eight weeks During these sessions, participants will practice in vivo, imaginal, and emotional exposure as well as continue these exposure exercises every day at home.

This is a brief psychotherapy that uses the PTSD Coach mobile app developed by the study team. The PTSD Coach app incorporates evidence-based assessment, psychoeducation, and cognitive behavioral therapy and self-management strategies that are customizable to the user.

  • Have had psychotropic medication stability for at least 4 weeks

You may not qualify if:

  • High risk of suicide (defined as meeting criteria for Action Step 3 on the Participant Suicide Risk Screening form
  • Severe alcohol or substance use disorder (moderate-severe alcohol use disorder on Alcohol Use Disorders Identification Test (AUDIT) (scores ≥ 15) or high risk on National Institute on Drug Abuse Quick Screen (scores ≥ 27))
  • Active psychosis or unmanaged bipolar disorder

Model Details: All eligible participants will initially be randomized to one of the two first-stage options, either PE-PC or PTSD coach with clinician support. Participants that have experienced less than a 15-point reduction, have a PCL score of greater than 60 ("very severe"), or cannot be reached for assessment will be classified as slow responders and will be re-randomized to one of two second-stage tactics, either (a) continue in their first-stage treatment strategy, or (b) step up to full PE. Participants who have experienced at least a 15-point symptom reduction or have a PCL score of less than 29 will be classified as early responders and will step down to a lower intensity of their current treatment strategy (i.e., early responders will not be re-randomized).
