The Consortium of Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) consists of five study sites and a coordinating center. Initiated in 1990, LONGSCAN projects are following samples of children who were maltreated or at risk for maltreatment from age 4 until they reach adulthood. A fourth five-year cycle for these grants was funded in September, 2005. Interviews and assessments with children and parents are planned to occur every two years.
