Unintentional injury is the leading cause of death and disability in U.S. children and the home is the single most common location of injury. The first specific aim of this project involves the design, conduct, and analysis of a prospective 36-month randomized controlled trial to reduce residential unintentional injury. The intention-to-treat analyses of the longitudinal data will involve repeated measures, following children from birth to 36 months of age, the group at highest risk for residential injuries. In secondary analysis, the project will examine the effect of the intervention by levels of parental supervision to test whether the effect was greater for households with lower parental supervision.

The second specific aim will examine causal determinants of parental supervision and its ultimate effects on unintentional residential injury. Using a theoretical model of supervision, data developed in the first specific aim, together with validated measures of caregiver traits such as maternal depression (Beck Depression Inventory), parental health locus of control and child injury-risk behavior (Injury Behavior Checklist), will be used to examine determinants of supervision. Unintentional residential injury will be modeled by integrating the quality of residential hazards, caregiver beliefs about residential safety, caregiver locus of control and depression, the quantity and quality of supervision, and child injury-risk behavior. A structural equation model incorporating parental supervision, the burden of residential hazards, and children’s injury-risk behaviors will be developed to explain residential injury. Maternal depression and other caregiver characteristics will in turn explain parental supervision.

This project will provide the primary investigator with experience and expertise to understand injury prevention and residential supervision through a multi disciplinary approach. This proposal will leverage the support and resources of the Cincinnati Center for Children’s Environmental Health to further the science of injury control.
