Brief summary
This single-arm pilot study (Phase 1) will test the preliminary efficacy of a virtually delivered, live-online 16-week group model of Internal Family Systems (IFS) for individuals with PTSD, called the PARTS program, on PTSD symptoms measured by Clinician-Administered PTSD Scale (CAPS-5). In addition, feasibility, acceptability, and effects on self-report PTSD and disturbances of self-organization (DSO) will be secondary outcomes.
Detailed description
The investigators will conduct a single-arm pilot study to test the preliminary efficacy of a virtually delivered, live-online 16-week group model of Internal Family Systems (IFS) for individuals with PTSD, called the PARTS program, on PTSD symptoms measured by Clinician-Administered PTSD Scale (CAPS-5). Secondary outcomes include feasibility and acceptability of the PARTS program measured by a Credibility/Expectancy Questionnaire (CEQ) and Treatment Satisfaction Questionnaire. Secondary clinical outcomes include the effects of the PARTS program on self-report PTSD and disturbances of self-organization (DSO). Exploratory aims of the study are to investigate the effects on emotion regulation (DERS), self-trauma fusion (iPRISM-trauma), disassociation (MDI), depression (CAT-DI), self-compassion (SCS-SF), perceived stress (PSS), mindfulness (TMS), and interception (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).

Insufficient level of severity of PTSD symptoms: PTSD score of less than 33 on the PTSD Checklist for DSM-V (PCL-5) at screening visit; 7. Inability to participate safely in the study intervention and without disrupting the group (in the opinion of principal investigator OR meeting any of the following criteria): * Past year history of a psychotic disorder or clinician confirmed active psychosis (Severe level of psychosis on PSY-S-CAT \> 60 will trigger the requirement of a clinical assessment prior to participation in the program) * Bipolar I disorder history or severe level of mania on CAT-M/HM (\>70) * Acute suicidality or self-injurious behavior * Severe depression, indicated by CAT-DI PHQ-9 equivalency score \>20 * Acute homicidality with plan and/or intent; * Hospitalization for suicide attempt or self-harm within three months of the enrollment period; * Severe Borderline Personality Disorder or other severe personality disorder that may lead to disruptions within the group; and/or * Moderate or severe Substance Use Disorder.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 24 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
| Measure | Time frame | Description |
|---|---|---|
| Retention | Week 16 | A secondary aim is to evaluate feasibility by demonstrating at least 50% of participants are retained in the program at 16 weeks.. |
| Acceptability as assessed by Satisfaction Survey | Week 16 | Participants will complete a satisfaction survey and rate their likeliness to recommend the program to a friend, on a five point Likert-type scale. An average greater than 3 out of 5 represents acceptability. |
| 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 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. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline Toronto Mindfulness Scale (TMS) at 16 Weeks | Week 16 | The TMS is a 13-item scale evaluating mindfulness factors of curiosity and decentering. |
| 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). |
| Change from Baseline Multidimensional Assessment of Interoceptive Awareness (MAIA-2) at 16 Weeks | Week 16 | The MAIA-2 is a 37-item self-report scale designed to assess multiple aspects of interoception and interoceptive awareness (e.g., body trusting). |
| Change from Baseline Pictorial Representation of Illness and Self Measure (PRISM) --Trauma at 16 Weeks | Week 16 | The Pictorial Representation of Illness and Self Measure (PRISM) is a visual method to assess the global burden of illness, measuring the participant's self-trauma fusion. Using the iPrism Lite ipad app, the user places a disk representing the illness in relation to a disk representing the self. |
| 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 Depression (CAT-DI) 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 will assess depression severity with the CAT-DI. |
| 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 Perceived Stress Scale (PSS-4) at 16 Weeks | Week 16 | The PSS-4 uses 4 items to measure the degree to which situations in life are stressful, evaluating how overloaded, unpredictable, and uncontrollable one finds one's life. Each item is scored on a 5-point Likert scale from 0 (Never) to 4 (Very often). |
