Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction)

Overview

Posttraumatic stress disorder (PTSD) is a common and disabling condition associated with intimate relationship problems and mental health problems in partners of those with PTSD. Recognizing the need to improve access to evidence-based interventions for those with PTSD and their families, our team has developed an Internet-delivered, self-help intervention to improve PTSD, enhance relationships, and improve partners' mental health: Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction). Couple HOPES presents text and video-based content across seven self-help intervention modules, with modest support from paraprofessional coaches. Although the Couple HOPES platform has been developed, it remains uncertain whether Couple HOPES is feasible, usable, and efficacious in reducing PTSD and enhancing intimate relationship functioning. The proposed project aims to refine and finalize Couple HOPES with couples that include a veteran, service member or first responder with significant PTSD symptoms. This project includes initial testing of the intervention's preliminary efficacy, safety, and feasibility in a series of 10 couples (Phase 1), then in an uncontrolled trial of 20 couples (Phase 2), and then a randomized clinical trial comparing its efficacy to a delayed intervention control condition in 70 couples. Potential benefits of this study include couples learning new skills to reduce PTSD symptoms and enhance relationship functioning, although this is not guaranteed. Risks include participants finding the assessments distressing, or possible worsening of PTSD symptoms or relationship functioning. These risks will be mitigated by continuous monitoring of PTSD symptoms, relationship functioning, and adverse events, and intervention by study staff.

Interventions

  • Behavioral: Couple HOPES Guided, Internet-Delivered, Self-Help Intervention
    • Couple HOPES is a guided self-help intervention for individuals with PTSD and their partners based on Cognitive-Behavioral Conjoint Therapy for PTSD (Monson & Fredman, 2012). This intervention consists of text and video-based content across seven intervention modules and phone and online-based coaching sessions with a paraprofessional. Participants are able to complete these modules in their own home or private location of their choosing. The primary outcomes are PTSD symptoms, relationship satisfaction, and the mental health and wellbeing of partners of those with PTSD.

Arms, Groups and Cohorts

  • Experimental: Immediate Couple HOPES
    • Immediately assigned to receive seven modules of an Internet-delivered self-help intervention with paraprofessional coaching for PTSD completed at the participant’s own pace within 8 weeks.
  • No Intervention: Delayed Intervention
    • Participants will not receive Couple HOPES for the first 8 weeks, and complete assessments at the beginning, middle, and end of this period. After this 8-week delay, participants will then receive seven modules of an Internet-delivered self-help intervention with paraprofessional coaching for PTSD completed at the participant’s own pace within 8 weeks.

Clinical Trial Outcome Measures

Primary Measures

  • PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-5 (PCL-5) with change measured as mean change from baseline
    • Time Frame: Baseline, week 3, week 8, approximately once a week during treatment (for up to 8 weeks), after 3 modules are completed or 3 weeks into treatment, after 7 modules are completed or 8 weeks into treatment, 3 month post-treatment follow-up
    • Scores on the PCL-5 range from 0 to 80, with 80 being the most severe PTSD symptoms.
  • Couple Satisfaction Index (CSI-4) with change measured as mean change from baseline
    • Time Frame: Baseline, week 3, week 8, approximately once a week during treatment (for up to 8 weeks), after 3 modules are completed or 3 weeks into treatment, after 7 modules are completed or 8 weeks into treatment, 3 month post-treatment follow-up
    • Score on the CSI-4 range from 0 to 21, with 21 being the most satisfied.

Secondary Measures

  • Mean change from baseline on Ineffective Arguing Inventory
    • Time Frame: Baseline, week 3, week 8, after 3 modules are completed or 3 weeks into treatment, after 7 modules are completed or 8 weeks into treatment, 3 month post-treatment follow-up
    • Score range from 0 to 40, with 40 representing highly ineffective arguing.
