ABSTRACT
This article provides an overview of multisystemic therapy (MST). Specifically, the theoretical and empirical foundations for the demonstrated clinical and cost effectiveness of MST in treating children and adolescents presenting serious clinical problems and their families are discussed. Key foundations include attention to the multidetermined nature of serious clinical problems, provision of services with high ecological validity, and use of intensive quality assurance mechanisms to support program fidelity. Issues pertaining to the successful transport of MST programs at clinical, organizational, and community levels also are highlighted.
