Trial Summary

What is the purpose of this trial?

This trial tests a new therapy program called PARTS against a nature-based therapy (NBSR-T) to help trauma survivors with PTSD. PARTS helps people manage their internal emotions, while NBSR-T uses nature to reduce stress. The goal is to see which method better reduces PTSD symptoms.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, it does exclude individuals with moderate or severe Substance Use Disorder and those using illicit drugs or non-prescribed controlled medications in the past 3 months.

What data supports the effectiveness of the NBSR-T and PARTS treatment programs for PTSD?

Research shows that intensive outpatient programs (IOPs) using trauma-focused treatments like Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) therapy are effective for PTSD, with high completion rates and significant symptom reduction. These programs have been shown to improve mental, physical, and social functioning in veterans, suggesting that similar intensive treatments like NBSR-T and PARTS could also be effective.12345

What safety data exists for the PARTS vs NBSR-T Programs for PTSD?

There is limited information on the safety of psychotherapy interventions like the PARTS and NBSR-T Programs, as adverse events are not consistently monitored or reported in behavioral health trials. Serious adverse events, such as suicide attempts, are usually tracked, but other side effects, like temporary increases in anxiety, are often not documented.678910

Treatment Details

Interventions

  • NBSR-T Program
  • PARTS Program
Trial Overview The PARTS Program—an intensive group therapy based on Internal Family Systems—is being tested against the NBSR-T control group. The main goal is to see if PARTS reduces PTSD symptoms more effectively than NBSR-T using various psychological measures.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: PARTSExperimental Treatment1 Intervention
The Program for Alleviating and Resolving Trauma and Stress (PARTS) Program is a 16-week group intervention model of Internal Family Systems (IFS), with 8 individual IFS clinical sessions on a biweekly basis, developed to resolve and alleviate trauma and stress for individuals diagnosed with PTSD.
Group II: NBSR-TActive Control1 Intervention
The Nature Based Stress Reduction for Trauma Survivors (NBSR-T) Program is a 16-week nature-based group intervention model, with 8 individual non-IFS clinical sessions on a biweekly basis, developed as an attention placebo control for individuals diagnosed with PTSD.

Findings from Research

An intensive outpatient program (IOP) for PTSD, offering Prolonged Exposure and Cognitive Processing Therapy three or more times a week, achieved a high completion rate of 87.3% among veterans, indicating strong acceptability.
The IOP demonstrated significant effectiveness, with a large effect size (d = 1.80) in reducing PTSD symptoms, suggesting it is a promising treatment option to enhance engagement and outcomes in PTSD care.
Feasibility of an intensive outpatient treatment program for posttraumatic stress disorder within the veterans health care administration.Yamokoski, C., Flores, H., Facemire, V., et al.[2023]
In a study of 2,643 veterans receiving treatment for PTSD, 25.9% experienced substantial improvement in symptoms, while 74.1% showed modest improvement, indicating that significant progress is possible in routine clinical practice.
The only strong predictor of substantial improvement was gender, with men having lower odds of achieving significant symptom reduction compared to women, suggesting that treatment approaches may need to be tailored based on gender differences.
Using patient-reported outcomes to understand the effectiveness of guideline-concordant care for post-traumatic stress disorder in clinical practice.Shiner, B., Gui, J., Leonard Westgate, C., et al.[2023]
Women veterans and those who started evidence-based psychotherapy (EBP) within a year of seeking mental health care had higher chances of improving their PTSD symptoms, indicating the importance of timely intervention.
Completing at least 8 sessions of EBP and receiving specific therapies like Prolonged Exposure (PE) or Cognitive Processing Therapy (CPT) individually were linked to better outcomes, suggesting that both the timing and type of treatment can significantly influence recovery.
