This report describes achievements of a Linn County (Oregon) project to design, implement, and evaluate a county-wide comprehensive interagency model for achieving improved outcomes for children with or at risk of developing emotional/behavioral disabilities. The project stressed systems change, driven by full parent participation and interagency collaborative strategies. The project's six major components were: (1) a county council which provided structure for the planning, implementation, and evaluation of the model; (2) a parent support and advocacy network; (3) a county-wide systems change process focused on the school environment; (4) regionalized interagency youth service teams for developing family service plans; (5) a coordinated system of service delivery and follow-up; and (6) a plan to integrate health and social services at school sites. Individual sections of this report address: goals and objectives, theoretical/conceptual framework, description of model and participants, methodological/logistical problems, research/evaluation findings, project impact, and additional information. Thirteen appendices include forms used to record staff time use, student and family profile information, perceptions of child progress, student self-assessment, family attitudes, and system change evaluation.
