This study explores the use of transcutaneous auricular vagus nerve stimulation (taVNS), a new form of neuromodulation which stimulates the ear. 20 healthy subjects without a past medical or psychiatric history will be recruited to participate in a phone screen followed by 1 lab visit. During the lab visit, subjects will participate twice in a validated stress induction technique called the cold pressor test, while concurrently receiving either active or sham taVNS. The cold pressor test consists of subjects placing their feet in an ice bath for a short period of time. Researchers will measure participant's body's responses (heart rate and blood pressure), while they receive taVNS (ear stimulation) and participate in the cold pressor test. Assessments of mood, anxiety, and stress will be collected at the beginning and end of the visit.
The purpose of this research is to test out a new way of treating generalized anxiety disorder (GAD) with low intensity focused ultrasound pulsation (LIFUP). If the subject agree to participate in the research study, the participation will last approximately 10.5 hours over seven (7) days. The visits are as follows: 1- consent and MRI, 2- and 3- focused ultrasound will be delivered outside of the MRI environment, 4- MRI plus focused ultrasound, 5- assessments 1 week post focused ultrasound, and 6- one month follow-up assessments. Research studies are voluntary and include only people who agree to take part.
The purpose of this study is to learn ways to improve treatments for Veterans with military sexual trauma (MST). The researchers want to learn whether combining evidence-based emotion regulation skills training with a trauma-focused therapy improves treatment outcomes. An evidence-based trauma treatment known as Prolonged Exposure will be used. Emotion regulation skills will also be included in treatment. Veterans with a positive or sub threshold diagnosis of PTSD who experienced a military sexual trauma (MST) will be included. Participants will complete up to twelve 90 minute sessions of PE with Dialectical Behavior Therapy (DBT) Emotion Regulation Skills Training followed by a post-treatment assessment. All aspects of the project including consent, baseline, treatment and follow-up will be completed either in person or via videoconferencing. Fifteen participants will be enrolled.
The purpose of this study is to explore the use of a new treatment program to improve medication adherence for people with HIV and PTSD for patients at MUSC Ryan White clinic. Participants will be assigned to one of two groups. Participants in Group A will be asked to attend 12 clinic sessions (twice a week for 6 weeks, 90-minute sessions) via telehealth or in person at the MUSC Ryan White clinic. Participants in Group B will receive a one session adherence intervention (60 minutes) and get the same standard treatment that someone with a trauma history and co-occurring HIV and PTSD symptoms would receive at a local Ryan White clinic. The study is provided at no-cost, and participants may learn useful information and coping skills while being in the study. It is hoped the information that we get from this study will help researchers and clinicians better design treatment programs for people living with HIV and PTSD. Participants will receive study compensation for their time.
In this study, patients will complete questionnaires to help us determine clinically relevant scores for a new patient-reported measure of body image distress following HNC treatment. A select group of patients will also undergo in-depth discussions to help us determine scores on the patient report measure that correlate with mild, moderate, and severe levels of image distress.
The current study aims to adapt and test a brief computer-assisted intervention for pregnant women with elevated posttraumatic stress symptoms. Twenty pregnant women in their first trimester will be invited to participate in the study if they endorse elevated posttraumatic stress symptoms. Along with self-report measures, hormones will be measured at baseline, one month post-intervention, three months post-intervention, and post-delivery. In addition, women will receive a psychoeducation + skills intervention during their first trimester and women will be offered a "booster session" intervention following delivery to enhance utilization of skills during a critical period for maternal mental and physical health outcomes.
This study will examine the neural circuitry associated with craving, behavioral disinhibition, and threat-reactivity. The study will involve 2 visits. During the first visit, participants will complete questionnaires and interviews in a private room and do some tests to measure alcohol use. During the second visit, participants will complete a neuroimaging scan of their brain.
PTSD is a prevalent condition for which veterans frequently seek treatment in the VA healthcare system. There are a number of first-line PTSD treatment approaches available, such as Prolonged Exposure and Cognitive Processing Therapy. However, the efficacy rates of these treatments is not as high as what has been observed with civilian populations and approximately 36% of individuals drop out of these treatments prematurely. A proposed alternative to these treatments is Written Exposure Therapy (WET), a brief, 5 session intervention that has been shown to reduce symptoms of PTSD and contribute to lower dropout rates. The goal of this study is to investigate whether WET is as effective compared to Prolonged Exposure (PE) in the treatment of PTSD in a sample of veterans diagnosed with PTSD. It will involve approximately 150 Veterans. This research is funded by the Department of Veterans Affairs.
