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.

Read this ADAA blog about things to know and questions to ask before committing to a clinical trial.

This project will examine changes in depression and anxiety following a 10-week intervention promoting nature-based physical activity in mental health settings. We will recruit ten licensed therapists whose caseload includes adults with depression and anxiety. Following a training by our team, each participating therapist will recruit six clients, who will be randomly assigned to the intervention or control condition. Clients in the intervention condition will engage in walk-and-talk therapy outdoors during weekly sessions and discuss strategies for being active outdoors on their own. We will assess changes in depression, anxiety, and nature-based physical activity in both groups.

The purpose of this randomized controlled trial is to evaluate whether the InMotion intervention, delivered via telehealth (using a HIPAA-compliant video platform or phone), which uses evidence-based behavioral and motivational counseling to increase daily physical activity, is an effective treatment for Major Depressive Disorder (MDD) for people who are at least one year out from sustaining a traumatic brain injury (TBI). The first aim is to compare the efficacy of the InMotion intervention to the waitlist control (WLC) condition on measures of depression severity and associated conditions in under-active adults with TBI and MDD. For the second aim the investigators plan to identify possible moderators of exercise treatment effects. The third aim will examine possible mediators of treatment outcome. In addition, the weekly dose of exercise, the extent to which exercise generates positive affect, and engagement in enjoyable or meaningful aspects of life will be explored.

This research study is studying how thoughts, feelings, surroundings, and individual biology may contribute to why and how people experience anxiety or depression. We are trying to find out the wide variety of reasons that people may experience anxiety or depression, and why different people are helped by different forms of treatment. We are trying to determine why people stay in treatment, and what factors contribute to a positive or negative response to treatment. These reasons may be due to thoughts, feelings, beliefs, personality, biology, social support network, life events, and barriers to treatment. A wide range of information about factors that impact anxiety and depression will be included. These include, among others, measures of inflammation, hormone levels, behavior, spoken language, personality, medical history, social determinants of health, and attitudes toward mental health and its treatment. The study involves psychological and psychiatric treatments in the form of psychotherapy and medication management. The participant will be asked to set specific goals for study treatment, and to provide videos between sessions about relevant medication, emotional, and sleep factors in their life. In summary, this study will collect biological, psychological, and social factors that may play a role in anxiety and depression. This will inform both individual's diagnosis and treatment and will be used in a later set of analyses that can inform diagnosis and treatment for other individuals who share similar characteristics.
