美国国家精神卫生研究所（NIMH）成立于1949年，是组成美国国立卫生研究院（NIH）的27个研究所和中心之一，NIH是世界上最大的生物医学研究机构。
NIMH是研究精神障碍的主要联邦机构，提供有关精神障碍的基本信息，一系列相关主题和最新的心理健康研究。通过基础和临床研究，转变对精神疾病的认识和治疗，为预防、康复和治愈铺平道路。
NIMH的目的不是提供具体的医疗建议，而是为用户提供信息，以更好地了解他们的健康状况和诊断出的疾病。
NIMH资助全国各地科学家的研究以及内部研究计划中的NIMH研究。通过其校外计划，NIMH支持全国和海外大学和其他机构的2，000多个研究补助金和合同。调查人员通过赠款申请自己提出项目，并且必须每隔一段时间申请续展，以便获得持续的资金。
大约有500名科学家在NIMH校内研究计划中工作。校内科学家的范围从在实验室工作的分子生物学家到在NIH临床中心与患者合作的临床研究人员。虽然在严格的同行评审系统的指导下，但校内科学家在快速跟进研究线索和意外机会方面具有独特的灵活性。此外，由于它涉及基础科学和临床试验，该计划旨在促进跨学科研究。
Founded in 1949, the National Institutes of Mental Health (NIMH) is one of the 27 institutes and centers that make up the National Institutes of Health (NIH), the world's largest biomedical research institution.
The NIMH is the primary federal agency for the study of mental disorders, providing basic information on mental disorders, a range of related topics, and the latest mental health research. Transform the understanding and treatment of mental illness through basic and clinical research, paving the way for prevention, recovery and cure.
The purpose of NIMH is not to provide specific medical advice, but to provide users with information to better understand their health status and diagnosed disease.
NIMH funds research by scientists across the country as well as NIMH research in internal research programs. Through its off-campus programs, NIMH supports more than 2,000 research grants and contracts at universities and other institutions across the country and overseas. Investigators propose their own projects through grant applications and must apply for renewals at regular intervals in order to receive ongoing funding.
Approximately 500 scientists work in NIMH's on-campus research programs. On-campus scientists range from molecular biologists working in labs to clinical researchers working with patients at NIH Clinical Centers. While guided by a rigorous peer-review system, on-campus scientists have unique flexibility in fast-tracking research leads and unexpected opportunities. In addition, since it involves basic science and clinical trials, the program aims to promote interdisciplinary research.
