Research Planning Work Groups produced "white papers" on the research needed to inform and shape the DSM-5  and the resulting work and recommendations were reported in an APA monograph  and peer-reviewed literature. Three additional white papers were also due by concerning gender issues, diagnostic issues in the geriatric population, and mental disorders in infants and young children. The DSM-5 Task Force consisted of 27 members, including a chair and vice chair, who collectively represent research scientists from psychiatry and other disciplines, clinical care providers, and consumer and family advocates. Scientists working on the revision of the DSM had a broad range of experience and interests. The APA Board of Trustees required that all task force nominees disclose any competing interests or potentially conflicting relationships with entities that have an interest in psychiatric diagnoses and treatments as a precondition to appointment to the task force.
