Five million young children suffer from traumatic brain injury (TBI) each year resulting in new child behavior problems, parental distress, and family dysfunction. Recent studies provide evidence that online skill building interventions can reduce caregiver distress and improve child adjustment following TBI. The investigators hypothesize that the I-InTERACT group will exhibit more effective parenting skills as well as better child functioning and lower levels of parental distress at follow-up than will the IRC group. The investigators overarching goal is to reduce the risk of long-term behavioral problems and disability in young children following TBI by equipping parents with increased coping and parenting skills in a cost effective fashion. Findings will be disseminated via presentations and peer-reviewed publications, a website and newsletter, workshops with advocacy groups, and technical assistance to interested parties
