A follow-up assessing uses of findings from NIMH-supported research on health and mental health services utilization in organized health care settings revealed a range of applications across the study sites. The research, conducted primarily for national policy purposes, had an impact on study sites in the following areas: clinician perceptions and attitudes about mental health services provided; program directions; fiscal policy; and further related research. Research team composition and dissemination of study findings are discussed in relation to the applications made.
