- Brief Summary
This pilot RCT will test the preliminary efficacy of an intensive group model of Internal Family Systems (IFS) called the Program for Alleviating and Resolving Trauma and Stress (PARTS) compared with a Nature-Based Stress Reduction for Trauma Survivors (NBSR-T) attention placebo control group at reducing PTSD symptom severity measured by Clinician-Administered PTSD Scale (CAPS-5). In addition, the effects of the interventions on self-reported PTSD symptoms, disassociation, and disturbances of self-organization (DSO), as well as mechanisms of emotion regulation, decentering and self-compassion will be secondary outcomes.
- Detailed Description
The investigators will conduct a pilot RCT to test the preliminary efficacy of the Program for Alleviating and Resolving Trauma and Stress (PARTS) compared with a Nature-Based Stress Reduction for Trauma Survivors (NBSR-T) control group at reducing PTSD symptom severity measured by Clinician-Administered PTSD Scale (CAPS-5).
Secondary clinical outcomes include the effects of the intervention on self-reported PTSD symptoms (PCL-5; CAT-PTSD), disassociation (MDI), and disturbances of self-organization (ITQ). Secondary mechanistic outcomes include emotion regulation (DERS), self-compassion (SCS-SF), and decentering (EQ-D) .
Exploratory aims of the study are to investigate the effects on depression (CAT-DI), mental health (CAT-MH scales), self-trauma fusion (PRISM-D), perceived stress (PSS), internalized stigma (ISMI), and interoception (MAIA-2). Additional exploratory outcomes include changes in outcome variables among PTSD subjects with baseline DSO and those without DSO as defined by the International Trauma Questionnaire (ITQ).

Group Intervention Description NBSR-T NBSR-T Program 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. PARTS PARTS Program 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.
- Primary Outcome Measures
Name Time Method Change from Baseline CAPS-5 at 16 Weeks Week 16 The primary aim of this study is to examine the preliminary efficacy of a live-online version of the PARTS program on PTSD symptoms measured by reduction in CAPS-5 over 16 weeks. The CAPS-5 is a 30-item questionnaire administered by a trained interviewer and is considered the "gold standard" assessment for PTSD diagnosis and symptoms as defined by the DSM-5. This measure also assesses the duration of symptoms, impact of symptoms on aspects of the participant's life, and if the participant meets criteria for the dissociative subtype of PTSD.
- Secondary Outcome Measures
Name Time Method Change from Baseline Disturbances of Self Organization -- International Trauma Questionnaire (ITQ-DSO-9) at 16 Weeks Week 16 The International Trauma Questionnaire (ITQ) is the first instrument designed to capture the ICD-11 PTSD and Complex PTSD (CPTSD) diagnoses. The last 6 items measure DSO symptoms characteristic of ICD-11 CPTSD. Each set of items have 3 severity of impact on functioning questions. The ITQ-DSO-9 includes just the 6 DSO items with 3 severity questions. The ITQ-DSO-9 will be used monthly for self-report of changes in DSO symptoms.
Change from Baseline Multiscale Dissociation Inventory (MDI) at 16 Weeks Week 16 The MDI is a 30-item self-report inventory measuring frequency of dissociative symptoms (e.g., depersonalization, derealization, emotional constriction, identity dissociation, etc.)
Change from Baseline Decentering (EQ-D) at 16 weeks Week 16 The EQ-D is an 11-item scale representing the Decentering items of the Experiences Questionnaire.
Change from Baseline Self-reported PTSD symptoms (PCL-5) at 16 Weeks Week 16 Participants will be sent a link to complete the PTSD Checklist for DSM-5 (PCL-5), which is a self-report measure with 20 items, which is designed to measure PTSD symptom severity over the past month as measured by the DSM-5, in combination with additional diagnostic tools.
Change from Baseline Self-reported PTSD symptoms (CAT-PTSD) at 16 Weeks Week 16 Participants will be sent a link to complete the CAT-MH (Computer Adaptive Testing for Mental Health) interview on a computer, tablet or phone. This outcome refers to the CAT-PTSD severity score.
Change from Baseline Self-Compassion Scale (SCS-SF) at 16 Weeks Week 16 The SCS-SF is an abbreviated 12-item form of the original 26-item Self-Compassion Scale. This scale evaluates 6 different aspects of self-compassion: Self-Kindness (e.g., ''I try to be understanding and patient toward those aspects of my personality I don't like''), Self-Judgment (e.g., ''I'm disapproving and judgmental about my own flaws and inadequacies''), Common Humanity (e.g., ''I try to see my failings as part of the human condition''), Isolation (e.g., ''When I feel inadequate in some way, I try to remind myself that feelings of inadequacy are shared by most people"), Mindfulness (e.g., ''When something painful happens I try to take a balanced view of the situation''), and Over-Identification (e.g., ''When I'm feeling down I tend to obsess and fixate on everything that's wrong.''). The scale is scored on a 5-point Likert scale (1 = Almost never; 5 = Almost always), and negative subscale items are reverse scored.
Change from Baseline Difficulties in Emotion Regulation (DERS) Scale at 16 Weeks Week 16 The DERS is a 36-item self-report scale designed to assess emotional dysregulation. The scale assess 6 aspects of emotional dysregulation: non-acceptance of emotional responses ("When I'm upset, I become embarrassed for feeling that way"), difficulties engaging in goal directed behavior ("When I'm upset, I have difficulty thinking about anything else"), impulse control difficulties ("When I'm upset, I lose control over my behaviors"), lack of emotional awareness ("When I'm upset, I take time to figure out what I'm really feeling (reverse-scored)", limited access to emotion regulation strategies ("When I'm upset, it takes me a long time to feel better"), and lack of emotional clarity ("I have no idea how I am feeling").
