This study examined mothers' teaching about home-safety issues to 24-30 month and 36-42 month old children, explored the relationship of teaching strategies to parenting styles, and assessed how these factors are related to children's risk of unintentional injury. A structured interview assessed home-safety issues relevant to falls, burns, cuts, poisoning, and suffocation/strangulation/choking. Mothers identified safety issues relevant to "her" child, and indicated the type and extent to which she utilized teaching as a strategy to address each safety issue. Standardized questionnaires provided information about parenting style and children's history of injuries. Results revealed that mothers' endorsements of home-safety issues did not vary with child age, mothers used teaching to manage safety issues for all types of injuries, and type of teaching strategy (explanations, rules, behavior modification) varied with parenting style. Greater use of explaining and less rule usage was linked to permissive parenting; these teaching strategies predicted children's medically-attended injury among highly-permissive mothers. Thus, teaching about safety is a common risk-management strategy mothers use to address hazards in the home. However, the specific type of teaching strategy used varies with parenting style, which has implications for children's risk of injury.
