Early intervention programs for young maltreated children and their families are critical to improving social, emotional, cognitive, and physical development. Fortunately, those in the field of maltreatment have identified early intervention treatments, prevention programs, and psychosocial treatments that show promise for maltreated children between birth and age 3 years. However, more research is needed to identify further beneficial treatments, test the limits of treatment effectiveness, and inform how to best apply these treatments without compromising their effectiveness. Also, research is needed to assess specific treatment components and program costs. This process will take considerable time, effort, and financial as well as political support, but it will enhance the lives of numerous individuals and benefit the community at large. In the meantime, we can deliver to maltreated children the early intervention services reviewed in the current document, with substantial confidence that the available research evidence is likely to apply. Additional information from empirical work completed for this study will help refine our ability to select the most applicable methods.
