Cognitive Processing Therapy (CPT) consists of discrete therapeutic components that are delivered across 12 sessions, but most Veterans never reach session 12, and those who drop out receive only 4 sessions on average. Veterans drop out because of time constraints, logistics, and lack of perceived benefit. Unfortunately, Veterans who drop out prematurely may never receive the most effective components of CPT and continue to experience symptom-related distress and numerous other negative outcomes, including lost productivity, substance use, later-life physical disability, reduced quality of life, and increased risk of suicide. The overall objective of this study is to adapt CPT into a brief, effective format. The rationale is that identifying the most effective intervention components and delivering only those components will make CPT deliverable in a shorter timeframe, thus improving efficiency, reducing drop-out related to poor treatment response, and ensuring that Veterans receive the most beneficial components of treatment, which will significantly improve their quality of life.

Mental contamination-an internal experience of dirtiness evoked in the absence of physical contact with an external source-has been linked to the development and maintenance of posttraumatic stress disorder (PTSD) following exposure to sexual abuse or assault (Adams et al., 2014; Badour et al., 2013; Brake et al., 2017). Mental contamination has been associated with greater PTSD severity (Rachman et al., 2015) and higher elevations in specific PTSD symptom clusters (particularly those of intrusive re-experiencing, negative cognitions/mood, and arousal/reactivity; Brake et al., 2019; Fergus & Bardeen, 2016). Additionally, trauma-related mental contamination has been linked to a number of negative posttraumatic emotions such as shame, guilt, disgust, and anger (Fairbrother & Rachman, 2004; Radomsky & Elliott, 2009). Despite clear and consistent links between mental contamination and problematic posttraumatic outcomes following sexual trauma, there is a dearth of research investigating how existing or promising new interventions for PTSD impact mental contamination. Written Exposure Therapy (WET) is a five-session treatment for PTSD that was designed to be both brief and easy to administer (Sloan et al., 2012). According to Sloan and colleagues' (2012) protocol, sessions broadly involve 30-minute exposures in which the patient writes about the events of their trauma in detail, followed by 10 minutes of discussing the exposure with the therapist. This treatment protocol has minimal therapist involvement, no homework assignments, and shorter treatment sessions. Research shows that WET is efficacious among different samples (e.g., survivors of motor vehicle accidents and combat veterans), has low dropout rates, treatment satisfaction is high, and the gains seen by participants after completion are maintained at follow-up (Sloan et al., 2012, 2013, 2018; Thompson-Hollands et al., 2018, 2019). Given these factors, WET has the potential to be a useful intervention in reducing symptoms of PTSD among a sample of survivors of sexual trauma. Given its relevance to this trauma population, a test of this intervention for its impact on reducing trauma-related mental contamination is also needed. The current study will use Single Case Experimental Design to isolate and evaluate the effects of WET in reducing both PTSD symptoms and trauma-related mental contamination among individuals with PTSD resulting from sexual trauma. Aims: Explore whether participants demonstrate reductions in mental contamination and PTSD symptoms in response to 5 sessions of WET. Visual inspection analysis and statistical methods will be used to draw conclusions regarding the effects of the interventions on PTSD symptoms and mental contamination. Read Less

Communication and Recovery Enhancement (CARE) is a 2-session early intervention for survivors of recent sexual assault and their supporters that aims to improve supporters' ability to respond effectively. The goal of this pilot trial is to understand the acceptability and preliminary efficacy of two versions of CARE: a version in which survivors and supporters attend both sessions together (dyadic CARE) and a version in which supporters attend sessions alone (supporter-only CARE). Survivors aged 14+ with elevated posttraumatic stress symptoms will enroll with a supporter of their choosing. Dyads will be randomized to dyadic CARE, supporter-only CARE, or waitlist control, and will complete self-report assessments at baseline, post-session-1, and follow-ups (1, 2, and 3 months post-baseline). Results will be used to inform future changes to CARE and determine whether a fully-powered randomized controlled trial is warranted. Read Less

This is a prospective randomized controlled trial comparing two ways of delivering Motion-assisted, Multi-modular Memory Desensitization and Reconsolidation (3MDR) therapy for posttraumatic stress disorder (PTSD). The study seeks 60 volunteers who have PTSD and are eligible for care in the Department of Defense healthcare system. There will be 10-14 therapy sessions that are 60-90 minutes long, about once a week, and symptoms will be assessed before and after the therapy as well as 3 and 6 months after completing therapy. 3MDR asks you to choose pictures and music that are integrated into a virtual reality environment. You will be walking on a treadmill throughout each therapy session, while the therapist stands next to the treadmill and asks you questions about the pictures you chose. Read Less

Smoking is the leading cause of preventable illness, disability, and death in the United States. The rate of smoking is disproportionately higher among Veterans with posttraumatic stress disorder (PTSD). Unfortunately, smoking cessation efforts that are effective in the general population have shown limited effectiveness in smokers with PTSD. The high smoking rate and difficulty with achieving abstinence indicate a critical need to develop effective interventions for Veterans who smoke and have PTSD. The investigators' data indicate that negative emotions and trauma reminders are associated with relapse for smokers with PTSD. In this context, an ideal strategy may be to combine evidence-based PTSD treatment with intensive smoking cessation treatment to maximize quit rates. Cognitive processing therapy (CPT) is a well-established evidence-based treatment for PTSD. The investigators have successfully developed a treatment manual that combines CPT with cognitive-behavioral counseling for smoking cessation. Contingency management (CM) is another intensive behavioral treatment that has been shown to help with reducing smoking. CM provides positive reinforcers such as money to individuals misusing substances contingent upon abstinence from use. The primary goal of this study is to evaluate the efficacy of a treatment that combines CM with cognitive-behavioral smoking cessation counseling, smoking cessation medication, and CPT. Proposed is a randomized, two-arm clinical trial in which 120 Veteran smokers with PTSD will be randomized to either: 1) COGNITIVE PROCESSING THERAPY with SMOKING ABSTINENCE REINFORCEMENT THERAPY (CPT-SMART) or 2) COMBINED CONTACT CONTROL, an intervention identical to CPT-SMART in PTSD and smoking treatment, except for using payment that is not contingent on abstinence. Specific aims include: AIM 1) To evaluate the efficacy of CPT-SMART on rates of short- and long-term abstinence from cigarettes; AIM 2) To evaluate the impact of CPT-SMART on treatment engagement and utilization; and an EXPLORATORY AIM) To explore mechanisms of CPT-SMART on long-term smoking abstinence. The positive public health impact of reducing smoking among Veterans with PTSD could be enormous as it would prevent significant smoking-related morbidity and mortality. Read Less

The proposed R21 project will attempt to further develop a novel intervention for posttraumatic stress symptoms inspired by the science of memory reconsolidation. Work in normal humans has shown that when a stable, consolidated memory is reactivated (i.e., retrieved) under appropriate conditions, it reverts to an unstable state, a process referred to herein as deconsolidation. In such a state, the memory is susceptible to the action of various "amnestic" agents that may inhibit its reconsolidation, thereby weakening it. The β-adrenergic blocker propranolol (PPNL) possesses such amnestic properties. More recent research has found that in order to initiate deconsolidation, there must be a prediction error, or mismatch, between what is expected and what occurs when the memory is reactivated. Prior placebo-controlled, randomized clinical trials (PBO-RCT) from our laboratory have found that when propranolol is administered concomitant with the reactivation of a psychologically traumatic memory, the memory is weakened, as revealed by subsequent lower physiological (heart rate, skin conductance, facial electromyogram) responding during script-driven mental imagery. Clinical applicability was evaluated in a PBO-RCT, in which PTSD participants receiving propranolol underwent six weekly sessions of 10-20 min of "standard" (STD) traumatic memory reactivation stimulated by reading a narrative. At post-treatment, these participants showed a greater reduction of PTSD symptoms compared to participants who had taken PBO. The goal of the proposed study is to test whether intentionally incorporating innovative mismatch (MM) into traumatic memory reactivation can improve upon physiological responding during script-driven mental imagery. Participants will be randomized to one of 2 treatment arms: STD/PPNL and MM/PPNL. A baseline assessment will measure psychophysiological responsivity to script-driven mental imagery (target measure). PPNL will be administered 90-min prior to each of six weekly 10-20 min. traumatic memory reactivation sessions. In the MM condition, a different, unexpected mismatch (e.g., singing the narrative) will be incorporated into the reactivation. In the STD condition, the participant will read the narrative the same way each time. The focus of the R21 proposal will be to assess whether the MM/PPNL group shows lower subsequent physiological responses than the STD/PPNL group Read Less

This study will deploy a scalable secondary prevention program that leverages existing foster youth transition services to improve mental health functioning and service use before and after exiting foster care. Our short-term objective is to remotely test a group intervention called Stronger Youth Networks and Coping (SYNC) that targets cognitive schemas influencing stress responses, including mental health help-seeking and service engagement, among foster youth with behavioral health risk. SYNC aims to increase youth capacity to appraise stress and regulate emotional responses, to flexibly select adaptive coping strategies, and to promote informal and formal help-seeking as an effective coping strategy. The proposed aims will establish whether the 10-module program engages the targeted proximal mechanisms with a signal of efficacy on clinically-relevant outcomes, and whether a fully-powered randomized control trial (RCT) of SYNC is feasible in the intended service context. Our first aim is to refine our SYNC curriculum and training materials, prior to testing SYNC in a remote single-arm trial with two cohorts of 8-10 Oregon foster youth aged 16-20 (N=16). Our second aim is to conduct a remote two-arm individually-randomized group treatment trial with Oregon foster youth aged 16-20 with indicated behavioral health risk (N=80) to examine: (a) intervention group change on proximal mechanisms of coping self-efficacy and help-seeking attitudes, compared to services-as-usual at post-intervention and 6-month follow-up: and (b) association between the mechanisms and targeted outcomes, including emotional regulation, coping behaviors, mental health service use, and symptoms of depression, anxiety, and PTSD. Our third aim is to refine and standardize the intervention and research protocol for an effectiveness trial, including confirming transferability with national stakeholders. Read Less

Posttraumatic stress disorder (PTSD) afflicts many war Veterans, but often they are reluctant to seek help despite availability of effective treatments. Family members are key sources of support who can help encourage such Veterans to initiate mental health services. Toward that goal, VA provides telephone coaching to family members through its Coaching Into Care (CIC) program to help get their Veterans into care. While CIC enjoys high caller satisfaction, it has shown only modest success getting Veterans into care. Blended interventions that include professional support and technology-based interventions offer promise for improving effectiveness of services. Therefore, this study tests an intervention that blends CIC calls with a web program called VA Community Reinforcement and Family Training (VA-CRAFT). VA-CRAFT is a translation of an empirically-validated model intended to help Veterans by training their family members to effectively promote care-seeking. If successful, this approach will support families and help more Veterans receive needed mental health care for PTSD. Read Less

The goal of this clinical trial is to compare the combination of Massed Prolonged Exposure (PE); a behavioral therapy for PTSD) and a stellate ganglion block (SGB; an injection of a local anesthetic into the front of the neck) with Massed Prolonged Exposure and a sham injection in a sample of military service members or retirees with PTSD. The main questions it aims to answer are: (1) Does the addition of an SGB improve treatment outcomes associated with Massed PE and (2) Do differences in psychophysiological arousal during the exposure portion of treatment help explain treatment outcomes for PTSD. Participants will receive ten 90-minute session of Massed PE. Between the first and second Massed PE sessions, half of the participants will receive a SGB, and half will receive a sham SGB. Read Less
