Under a six-year grant from the U.S. Department of Health and Human Services Substance Abuse and Mental Health Services Administration (SAMHSA-Center for Mental Health Services), Nassau University Medical Center and New York State Families Together have created the Nassau County Family Support System of Care (NCFSSOC) to provide a single point of access to care for emotionally disturbed children and youth and their families. Community Science is working closely with these two organizations to evaluate the NCFSSOC and use the findings to support improvements in the system of care. Community Science’s activities to date include developing a logic model, assessing the community, and cooperating with a national evaluator to generate questions about the effectiveness of the NCFSSOC. We are responsible for the recruitment and retention of parents and children in this longitudinal study. (2008-present)
