Stress Disorders, Post-Traumatic; Mental Disorders

PTSD is common among Veterans with serious mental illness (SMI). Co-occurring PTSD and SMI lead to poorer mental health and physical functioning than either diagnosis alone. Despite known high prevalence rates of PTSD in SMI populations as well as disparities in prevalence and treatment use for Black, Indigenous, and other people of color (BIPOC), little research has been done to: a) evaluate leading treatments for PTSD in individuals with SMI, and b) develop culturally responsive methods to integrate with PTSD treatments for SMI Veterans. This study aims to address research and clinical gaps by: a) testing the feasibility and acceptability of Written Exposure Therapy (WET), a VA evidence-based psychotherapy for PTSD in Veterans with SMI, and b) incorporating culturally responsive assessment methods. Results from this study will inform whether WET and culturally responsive assessment are feasible to implement, acceptable to Veterans with SMI, and worth examining in standard or optimized form in a larger clinical trial.

The goal of this clinical trial is to learn if Sensory motor arousal regulation treatment (SMART) works better than treatment as usual (TAU) to treat youth 7-17 years with complex trauma histories and self-regulation difficulties. The study also will investigate which patients will benefit more from SMART (treatment effect heterogeneity) and whether therapeutic alliance mediates effect. The main hypotheses the trial aims to answer are: 1. Main effects: The SMART model approach will be more effective than ordinary treatment (control condition), in terms of improvement from therapy starts to 6 and 12 months follow up, for: 1. Regulatory capacities of emotions and bodily states, attention and behavior, and self and social relations 2. Trauma symptoms of re-experiencing, avoidance/ numbness and hyperarousal and sense of threat (core PTSD symptoms) and disturbances in self-organization (affect, self-concept; relations - core complex PTSD symptoms) 3. Internalizing symptoms (somatic complaints, anxiety symptoms and depression symptom severity) and Externalizing symptoms (conduct problems, aggression, inattention, and social problem severity) 4. Psychosocial strengths - prosocial behavior, subjective well-being and impairment in peer relationships, family relationships, and academic/school functioning 2. Exploration of mediation: When comparing SMART and ordinary treatment (TAU), (i) therapeutic alliance is higher in SMART, and (ii) a better treatment effect in SMART is partially mediated by therapeutic alliance 3\. Exploration of treatment effect heterogeneity (moderators): Effects of SMART treatment compared to TAU vary between: patients with low versus high level of self-regulation difficulties (full vs partial Developmental trauma disorder), patients with extensive vs less extensive developmental trauma exposure, adolescents (13-17 years) vs younger children (7-12 years), and patients exposed to trauma early in life vs in their teens At each site, eligible participants are randomized to SMART or ordinary treatment/ TAU. Investigators acquire study data at baseline and outcome data at follow up after 6 and 12 months, and measure therapeutic alliance twice during the treatment process.
