Trial Summary

What is the purpose of this trial?

The R33 will be a randomized controlled trial to replicate changes in the targets (unproductive processing, avoidance, reward deficits) from the R61 phase in a larger sample of 135 participants who have experienced a destabilizing life event involving profound loss or threat, report persistent stressor-related symptoms of PTSD and/or depression, and are elevated on symptoms related to 2 of the 3 therapeutic targets. Additionally, this study will examine Positive Processes and Transition to Health (PATH)'s impact on stressor-related psychopathology in comparison to Progressive Muscle Relaxation (PMR). In the R33 phase, the investigators will examine changes in target mechanisms predicting improvements in PTSD and depressive symptoms, as well as feasibility and acceptability. Patients will receive 6 sessions of PATH or PMR (with 2 boosters, if partial responders). Primary targets will be assessed at pre-treatment, week 3, post-treatment, and at 1- and 3-month follow-up; secondary targets at pre-treatment, weekly during treatment, post-treatment, and at 1- and 3-month follow-ups.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does require that your dose of psychotropic medications has been stable for the past 3 months.

What data supports the effectiveness of the treatment PATH and PMR for PTSD and Depression?

Research on similar treatments, like Mindfulness-Based Stress Reduction (MBSR) and Multi-modular motion-assisted memory desensitization and reconsolidation (3MDR), shows positive changes in veterans with PTSD, such as improved engagement and emotional processing, which may suggest potential benefits for PATH and PMR. ^{1 2 3 4 5}

How does the PATH vs PMR treatment for PTSD and Depression differ from other treatments?

The PATH vs PMR treatment is unique because it focuses on positive processes and progressive muscle relaxation, which may help improve self-related processes and functional connectivity in the brain, particularly in areas affected by PTSD. This approach is different from traditional therapies that often focus on exposure to trauma memories or medication. ^{6 7 8 9 10}

Treatment Details

Interventions

• Positive Processes and Transition to Health
• Progressive Muscle Relaxation

Trial Overview This study tests the Positive Processes and Transition to Health (PATH) program against Progressive Muscle Relaxation (PMR) in helping individuals cope with stress-related symptoms from PTSD and depression. Each participant will receive six sessions of either PATH or PMR therapy to see which is more effective at improving mental health outcomes.

Participant Groups

Group I: Positive Processes and Transition to Health (PATH) Experimental Treatment 1 Intervention

PATH includes six 60-90 min, weekly sessions, with two booster sessions for partial responders. Session 1 provides the PATH rationale and a review of life events (PATH of life: negative and positive). A rationale for an explicit focus on positive events/emotions will be provided. Sessions 2-4 focus on a verbal narrative of the destabilizing life event, reminiscence and processing of a major positive life event, and real-life practice to enact what was taught. Sessions 5 focuses on constructive processing and provides opportunity for integration and consolidation of learning. Session 6 focuses on future negative and positive events to promote application of new learning and resilience. Booster sessions focus on positive and negative life events since the last session and adaptive processes (constructive processing, approach, and reward). All sessions will include cultivation and elaboration of positive emotions to promote engagement and to build on the benefits of positive emotions.

Group II: Progressive Muscle Relaxation (PMR) Active Control 1 Intervention

PMR will be adapted from Berstein, Borkoveck, and Hazlett- Stevens (2000). PMR will be conducted in six, 60-90 min individual weekly sessions with a study therapist. Muscle groups are tightened and then relaxed with the attention of the patient focused on the contrast between tension and relaxation. Through regular practice, the person becomes more aware of tension in the body and can induce relaxation as needed (Field, 2009). During the six sessions of training, patients will be encouraged to practice PMR and learn how to deliberately induce physical relaxation to reduce stress and mental tension. Sessions will move from relaxation of 16-muscle groups to 7 muscle groups, 4 muscle groups, and finally to relaxation by recall. Patients will be instructed to practice daily, if possible, but at least two or three times a week, and to integrate the practice into their daily life. They will be provided with audio recordings and homework reporting forms to assist their home PMR exercises.

Findings from Research

In a study of 47 veterans with PTSD, Mindfulness-Based Stress Reduction (MBSR) did not show reliable effects on PTSD or depression symptoms compared to treatment as usual, although it did improve mental health-related quality of life immediately after treatment.

Veterans who attended at least 4 MBSR classes experienced medium to large improvements in depression, mental health-related quality of life, and mindfulness skills, suggesting that participation in MBSR may lead to meaningful benefits for some individuals.

The 3MDR intervention effectively engages veterans with treatment-resistant PTSD by facilitating the processing of traumatic memories, leading to positive changes such as increased self-understanding and emotional regulation, even if not all participants experienced symptom improvement.

Veterans reported unique aspects of 3MDR, such as walking towards trauma-related images, which contributed to their treatment experience, suggesting that the intervention may provide benefits beyond just reducing PTSD symptoms.

In a study of 390 PTSD patients treated with sertraline or paroxetine over 12 weeks, both medications showed better outcomes than placebo, but individual responses varied based on factors like gender and trauma history.

The research identified three distinct response classes among patients: fast responders, those with low pretreatment symptom severity, and those with high pretreatment severity, suggesting that longer time since trauma may enhance treatment benefits.

In a study of 53 adults with PTSD undergoing cognitive processing therapy (CPT), dropout rates were significantly higher (39.7%) compared to written exposure therapy (6.4%), indicating a need to address factors influencing treatment retention.

The research identified that higher levels of physiological distress and cognitive emotional processing were associated with lower dropout rates, while avoidance behaviors predicted higher dropout, suggesting that targeting these factors early in treatment could improve engagement and outcomes.

A study of 2686 veterans with PTSD revealed five distinct treatment response trajectories, indicating that severity of PTSD at intake significantly influences treatment outcomes, with some experiencing minimal change and others showing substantial improvement.

Depression and guilt were identified as key predictors of treatment response, suggesting that addressing these issues before starting PTSD therapy could enhance treatment effectiveness, especially for those with severe PTSD.

In individuals with PTSD, the periaqueductal gray (PAG) shows stronger functional connectivity with the default mode network (DMN) during trauma-related stimulus processing compared to healthy individuals, indicating altered brain function associated with self-related processes.

The study found that the PAG has increased excitatory connectivity to key areas of the DMN (precuneus and medial prefrontal cortex) in PTSD patients, suggesting that these changes may contribute to the clinical symptoms experienced during trauma-related processing.

The study evaluated a new psychophysiological measure, psychophysiological reactivity to script-driven imagery (SDI-PR), in diagnosing PTSD, involving 36 participants over an initial visit and a follow-up after 6 months.

SDI-PR demonstrated strong stability and convergent validity with the established Clinician-Administered PTSD Scale (CAPS), suggesting it could serve as a reliable adjunctive tool for diagnosing PTSD by capturing underlying physiological responses.

In a study involving 20 PTSD patients and 20 matched trauma-exposed controls, it was found that both groups exhibited similar functional and anatomical connectivity patterns in the default mode network (DMN), suggesting that these brain mechanisms are affected by trauma regardless of PTSD diagnosis.

The study revealed that the integrity of specific brain regions in the DMN correlated strongly with the severity of PTSD symptoms, indicating that both anatomical and functional connectivity are important in understanding the disorder, and that trauma type and timing can further influence these connectivity patterns.

In a study of 215 breast cancer patients undergoing chemotherapy, higher levels of posttraumatic stress symptoms (PTSS), particularly hyperarousal, were linked to increased sleep disturbance and fatigue over time.

The findings suggest that addressing PTSS and sleep disturbances early in cancer treatment could help prevent fatigue, highlighting the importance of early intervention in managing these symptoms.

In a randomized controlled trial of written exposure treatment for PTSD, initial physiological arousal was linked to treatment outcomes, indicating that how a person reacts physically at the start can influence their recovery.

However, changes in physiological arousal during and between therapy sessions did not correlate with treatment gains, suggesting that self-reported feelings of arousal may be more important for understanding the effectiveness of exposure therapy.
