One seminar participant discussed the reasons why integrated approaches to adolescent health problems are gaining more support, obstacles to integration, and comprehensive youth programs in Washington, D.C. Another participant emphasized that the Office for Substance Abuse Prevention (OSAP) has primary responsibility at the Federal level for community-based and other drug abuse prevention and intervention programs. The OSAP supports programs for high-risk youth and families through demonstration grants, communication programs, and technical assistance to organizations and communities. Service integration is a major policy and program strategy shared by demonstration projects in an effort to eliminate gaps and fragmentation in youth health services. These projects reach beyond health systems to include linkages with education, juvenile justice, child welfare, social service, and employment and training service systems. The attainment of service integration at the patient, agency, community, and Federal level is discussed, and programs promoting integrated services for adolescents are described. 28 references, 1 figure.
