This final report describes the outcomes of four demonstration projects, funded in 1990 in Oregon, on early identification and prevention of mental and emotional disorders in children. The intention of the projects was to find ways to identify children who are at risk of suffering emotional disorders and intervene early enough to prevent these disorders. The first program described, the Interpersonal Cognitive Problem Solving Project, trained 1,400 children in social problem solving skills. In the second program, the Temperament Project, 188 parents received temperament services. The third project, the Jackson County Early Intervention Mental Health Project, provided special friends for 370 children who were at-risk. In the last project, the Family Service Project, close to 350 families were provided with parent education and support groups with concurrent and follow-up home visits. The report provides a description of each project, discusses progress since the interim report, evidence of the project's impact, and future plans. Results from the projects indicate positive changes in social behavior and child rearing practices. (CR)
