جامعة كاليفورنيا، لوس أنجلوسMindful Self-Compassion to Address PTSD and Substance Use in Unhoused Women (MSC for PTSD)
PTSD/SUD can be costly and difficult to treat, with treatment completion often low and relapse rates often high. Low-cost, complementary interventions, such as self-compassion (SC) interventions, which target key mechanisms that maintain PTSD/SUD, could improve treatment outcomes. SC interventions include practices that build skills to improve emotional responses, cognitive understanding, and mindfulness. Recent research supports the benefit of SC interventions for reducing PTSD, SUD, and related comorbidities, potentially with large effects. However, sample sizes have generally been small and randomized designs infrequently used. Moreover, while SC interventions may act to improve key mechanisms of treatment response and/or symptom maintenance (e.g., emotion regulation/dysregulation, trauma-related guilt, trauma-related shame, moral injury, and craving), such mediating factors have been underexplored. To address these limitations, the present proposal will implement community-based research principles and use a two phase, mixed-method design to adapt and test a widely used SC intervention (Mindful Self Compassion; MSC) for use with a sample of WEH with PTSD/SUD. The project will be conducted in partnership with a state-funded drug treatment facility that serves women and families experiencing high health disparities.
Phase I was completed in 2023 and adapted the standard MSC course for use with trauma-exposed WEH with PTSD/SUD using the ADAPT-ITT model, an eight-stage model that engages community partners to increase feasibility and acceptability of interventions for at-risk populations.
Phase II will be an open-label cluster randomized clinical trial (N=202) to test the benefit of the adapted MSC at improving primary (PTSD, substance use) and secondary outcomes (depression, anxiety, hopelessness) among a sample of WEH with PTSD/SUD residing in a residential drug treatment site. MSC (n=101) will be compared to Treatment as Usual (TAU; n=101). WEH in the MSC group will complete a 6-week (six sessions plus a half-day retreat) MSC intervention.
The TAU group will engage in weekly check-ins with the research team but will not receive an intervention. WEH will be assessed at baseline, immediately post-intervention, and at a 4-month follow-up. One-on-one interviews will be conducted with the MSC group to collect qualitative data on experiences. An exploratory aim will be to elucidate mechanism of treatment-response and maintenance or remission of PTSD symptoms. These potential mechanisms will include SC, emotion regulation/dysregulation, trauma-related guilt, trauma-related shame, moral injury, and craving.
Results may inform treatment for PTSD/SUD in WEH and other groups experiencing high health disparities and provide valuable insights into mechanisms underlying PTSD/SUD symptoms over time. Findings are relevant to military populations, which experience high rates of PTSD/SUD, and other populations disproportionately exposed to trauma.

تجريبيةMindful Self Compassion Classes (MSC) is a mind-body integrative health intervention that utilizes meditations, other contemplative practices, home practices, and experiential exercises (including group discussions) to increase SC. MSC can be done in groups of 10-25. To increase feasibility of MSC for use in residential drug treatment facilities we will aim to adapt MSC to 7 sessions (6 weekly sessions in alignment with the MSC short course plus the half day retreat included in the full course to facilitate skill consolidation). Sessions will be conducted in a group-based format: prior research found group-based formats equivalent to individual-level interventions for PTSD/SUD. | Mindful Self Compassion (MSC) is a mind-body integrative health intervention that utilizes meditations, other contemplative practices, home practices, and experiential exercises (including group discussions) to increase SC.

تجريبيةTreatment as Usual Selecting appropriate attention control groups for behavioral intervention research, particularly for mindfulness-based interventions, can be problematic. Comparator groups often also improve as they tend to target related mechanisms (e.g., social support, health behaviors, improved attention). After weighing the pros and cons, a "treatment as usual" (TAU) approach was selected, whereby the MSC will be compared to TAU. However, to control for the confound of weekly compensation, TAU participants will meet with study staff seven times over the 6-week period and fill out short psychosocial surveys on non-distressing topics (e.g., personality tests, attitudes surveys) in exchange for compensation commensurate with the MSC group. We believe this will also help with retention of the TAU group over time and strike an appropriate balance between controlling for the effects of study participation while minimizing confounds that often occur with active control groups in behavioral trials. | العلاج كالمعتاد (TAU) Selecting appropriate attention control groups for behavioral intervention research, particularly for mindfulness-based interventions, can be problematic.

PTSD | PTSD symptoms will be measured using the PTSD Checklist for Diagnostic and Statistical Manuel of Mental Disorders, DSM-5 (PCL-5), which will be scored continuously and according to diagnostic criteria.2 The PCL-5 initially starts with the identification of the presence of exposure to a Diagnostic and Statistical Manual of Mental Disorders, DSM-V traumatic event; assesses actual or threatened death, serious injury or sexual violence; and whether the person directly experienced it. Twenty additional items assess all four B-E criteria (re-experiencing, avoidance, negative thoughts or cognitions, hyperarousal), assessed on a Likert-type scale from 0 (not at all) to 4 (extremely). Treatment response will be defined as a ≥ 5-point reduction in symptoms and clinically meaningful improvement as ≥ 10-point reduction in symptoms. PTSD will be assessed for worse lifetime event and (if applicable) worst event in the past year. | T1 (baseline, enrollment), T2 (immediate follow-up), T3 (4-months post-baseline) |
Alcohol Use Disorders Identification Test (AUDIT) | The AUDIT is part of the National Institute on Drug Abuse (NIDA) Clinical Trials Network (CTN) Common Data Elements for use in clinical trials. The Audit is a 10-item alcohol screen that helps identify persons who are hazardous drinkers or who have active alcohol use disorders. It can be calculated as a sum score and will be analyzed as a continuous and categorical (yes/no used alcohol) outcome. | T1 (baseline, enrollment), T2 (immediate follow-up), T3 (4-months post-baseline) |
Drug Abuse Screening Test (DAST) | The DAST is a 10-item brief, self-report instrument for population screening, clinical case finding and treatment evaluation research. It can be used with adults and older youth. The DAST-10 yields a quantitative index of the degree of consequences related to drug abuse. The instrument takes approximately 5 minutes to administer and may be given in either a self-report or interview format. The DAST may be used in a variety of settings to provide a quick index of drug abuse problems. It will be evaluated continuously and as a categorical outcome (yes/no). | T1 (baseline, enrollment), T2 (immediate follow-up), T3 (4-months post-baseline) |

Beck Hopelessness Inventory | This twenty-item measure has been widely used to assess hopelessness through a series of true/false statements (1, 0) that create a sum score. | T1 (baseline, enrollment), T2 (immediate follow-up), T3 (4-months post-baseline) |
Anxiety (PROMIS) | This clinically valid, 7 item measure has been developed as part of the National Institute of Health (NIH) toolkit to assess anxiety in individuals 18 and older. Endpoints range from 1=never to 5=always. It can be used as a sum score and categorizes responses as "none to slight", "mild", "moderate," and "severe". | T1 (baseline, enrollment), T2 (immediate follow-up), T3 (4-months post-baseline) |
Depression (PROMIS) | This clinically valid, 8 item measure has been developed as part of the NIH toolkit to assess depression in the past two weeks. It assesses symptoms ranging from 1=never to 5=always and can be used in individuals 18 and older. It can be used as a sum score and categorizes responses as "none to slight", "mild", "moderate," and "severe". | T1 (baseline, enrollment), T2 (immediate follow-up), T3 (4-months post-baseline) |
Loneliness (PROMIS) | This clinically valid, five item measure was developed as part of the NIH toolkit to assesses feelings of social isolation on a five-point scale from 1=never to 5=not at all. | T1 (baseline, enrollment), T2 (immediate follow-up), T3 (4-months post-baseline) |
