Before medications are approved by the U.S. Food and Drug Administration (FDA) or before certain therapy methods are widely accepted as effective, they are tested on people who volunteer to participate in a clinical trial.

Organizations across the country are looking for people like you to take part in their research studies. The list of studies below have been selected from ClinicalTrials.gov based on their inclusion of one or more of the following terms: anxiety disorders, depression, OCD, PTSD, and bipolar disorder.

The Anxiety and Depression Association of America (ADAA) is supportive of research that is conducted through clinical trials. Participating in research can potentially help change the mental health outcomes for you and others who suffer anxiety, depression, and related disorders. You may learn about new interventions/treatments that are being considered.

Severe childhood adversity accounts for a large portion of psychiatric illness, and an increased risk for major depressive disorder (MDD). For some individuals, childhood adversity has negative psychological and medical consequences; others preserve mental and physical health despite such experiences (they are resilient). In spite of this, little is known about the neurobiological mechanisms related to childhood adversity, especially oxidative stress abnormalities in the brain. To fill this gap, this study combines functional, structural, and molecular imaging approaches to examine the role of oxidative stress abnormalities related to childhood adversity.

Decision-making is an important process that is frequently shown to be impaired in patients with depression. While a number of preclinical and clinical studies have identified key regions involved in this process, it remains unclear exactly how these regions are influencing choice behavior especially when choices become more challenging. The goal of this project is to understand how these regions, such as the cingulate cortex, impact difficult choice behavior. Specifically, the researchers are interested in learning how disruptions in cognitive control might impact choice preferences during difficult decisions in depressed patients. To do this, this study will recruit participants with depression (as well as healthy controls) to perform game-like tasks in the laboratory while undergoing TMS or TI.

A Study of a Test for Postpartum Depression at Home
University of Virginia Postpartum Depression (PPD) Pregnancy

The study will seek to prospectively validate the Enlighten Device for prediction of PPD by examining true/false positive and negative rates of the test using PPD outcomes collected through 3 months postpartum; compare the accuracy of biomarkers and algorithm in determining risk for PPD in blood compared to saliva; determine the utility of a week 6 sample collection in identifying women who are currently experiencing PPD thus bringing them to clinical attention. Our population will consist of pregnant women aged 18 and older up to 33 weeks of gestation. This research involves two groups of potentially vulnerable subjects: pregnant women and their infants. Because this is a study of postpartum depression (PPD), inclusion of these two vulnerable subjects is required. The study will enroll 1000 pregnant non-adolescent women of childbearing age who meet eligibility criteria. This project will address the following Aims: Specific Aim 1: Prospective collection of true/false positive and negative PPD outcomes through 3 months postpartum. Primary Hypothesis H1a: 80% or greater of pregnant women who develop postpartum depression (PPD) by 3 months after delivery will be determined to be Biomarker Positive by the Enlighten Test in T3. Primary Hypothesis H1b: 10% or fewer of pregnant women who are determined to be Biomarker Negative by the Enlighten Test in T3 will develop PPD by 3 months after delivery. Exploratory Aim 1: Investigation of clinical factors that may be associated with false positive and false negative rates, such as: medication use, stressful life events, & sociocultural context. Specific Aim 2: Comparison of prospective biomarker calls made in blood samples compared to saliva samples using the Enlighten Test. Primary Hypothesis H2: Biomarker calls made using blood versus saliva samples will demonstrate a high concordance rate of 75% or higher. Exploratory Aim 2: In individuals who develop PPD by 3 months postpartum, conduct an epigenome-wide study (EWAS) in saliva to identify saliva-specific epigenetic biomarkers to improve the algorithm's ability to predict PPD using saliva in the third trimester and Week 6 samples. Specific Aim 3: Determination of the utility of the Enlighten Test in identifying women currently experiencing PPD at W6 postpartum. Primary Hypothesis H3: 80% of women who meet criteria for PPD at W6 will be Biomarker Positive. Participants will be screened during the second or third trimester and enrolled during the third trimester, before week 30 weeks of gestation. Participants may self- identify through study advertisements in participating clinics, social media outlets, and community outreach efforts. Enrolled participants will undergo blood collection during their 3rd trimester completed by mobile phlebotomists in-person through ExamOne (~27-30 weeks, a standard pregnancy-related blood collection timepoint) for completion of the Enlighten Device test, the blood-based epigenetic biomarker test. Participants will then be interviewed at 2 weeks, 6 weeks, and 3 months postpartum for the development of depression symptoms. They'll also complete a multitude of other outcome measures at each of these visits.

The goal of this open pilot trial is to learn if an adapted version of Cognitive Processing Therapy (CPT), delivered through telehealth, can treat posttraumatic stress disorder (PTSD) in adults who use syringe services programs. The main questions it aims to answer are: - Can the intervention be done in syringe services programs? - Are syringe services program clients and staff open to the intervention? - Can the intervention lower PTSD symptoms and help participants keep taking their medication for opioid use disorder (ex. Buprenorphine or methadone)? Participants will: - Attend 4-18 tele-delivered CPT sessions at the syringe services program - Complete between-session CPT practice with the support of SSP-based "coaches" - Meet with research staff monthly to complete surveys of their PTSD symptoms, drug use, and mental health

Although most people recover from acute pain (such as pain caused by injury, surgery, repetitive motion, or unknown causes), many people do not fully recover and will experience chronic pain. Untreated posttraumatic stress disorder (PTSD) appears to be a key risk factor for the transition from acute pain to chronic pain. However, few published studies have addressed the issue of preventing the transition from acute to chronic pain via PTSD reduction. This project will aim to test whether trauma-related PTSD symptoms can be reduced using either Stellate Ganglion Block (SGB) treatment or Cognitive Processing Therapy (CPT), and whether reducing PTSD symptoms can prevent the transition from non-injury based acute pain to chronic pain.
