Mental and Behavioral Health

HSR&D's Mental Health portfolio addresses broadly-defined mental health issues, including outcomes of care for mental illnesses and substance use disorders. Mental illness includes schizophrenia, bipolar disorders, depression, anxiety disorders, and post-traumatic stress disorders. Substance use disorders include addictions to alcohol and drugs. Current active projects include barriers to treatment-seeking, access to care intervention effectiveness trials, measurement of the outcomes of interventions, and the impact of co-occurring conditions (e.g., mental illness and substance use disorders; mental illness and chronic disease). Mental health is an HSR&D priority as described in the current Program Announcement of HSR&D Priorities.
