This paper describes a comprehensive approach to intervention and support for families of children experiencing traumatic brain injury (TBI) and behavior problems. It explains the need for child- and family-centered intervention approaches, discusses the theoretical basis and key features of one approach, summarizes the steps in the support process, and presents a case study of one family's efforts to support an 11-year-old boy with TBI and severe behavior problems. Five key features characterize the recommended approach: a theory-guided understanding of child behavior problems and family ecology; design of multicomponent, positive behavioral support plans; ensuring a "goodness-of-fit" between the support plan and family ecology; focus on building successful family routines; and development of collaborative partnerships. The seven-step behavioral consultation process recommended includes: (1) referral; (2) comprehensive assessment; (3) preliminary plan design; (4) team meetings and plan finalization; (5) implementation support; (6) continuous evaluation and plan revision; and (7) follow-up support. The entire process is illustrated in the case study in which clinically significant improvements in child behavior were achieved and maintained during follow-up measures 3 and 4 months after intervention.
