Motor vehicle crashes (MVCs) are a leading cause of death in children. Child restraint systems (CRS) are effective at protecting children in MVCs. Unfortunately, the majority of CRS on the road today are being misused, which limits the amount of protection they can offer. For example, caregivers often install CRS too loosely into their vehicle, neglect to attach the top tether to the anchor in the vehicle, or do not tighten the harness tightly enough around their child. Most CRS users are not aware they are making these potentially dangerous errors. Better education is necessary for caregivers who rely on CRS to protect their children in vehicles. The literature suggests that passive CRS instructions and features are inadequate for reducing misuse, but hands-on educational methods with real-time feedback are more effective. The studies presented here aim to explore several different approaches to understand and reduce CRS misuse. Targeted passive interventions were evaluated for top tether attachment and lower anchor (LA) tensioning. Active intervention in the form of a novel automated feedback system was also evaluated. The passive interventions examined in these studies were not effective in reducing CRS misuse. The data suggest that small changes to the visibility of different CRS features do not improve their usage. Additionally, simple repetition of installation tasks resulted in the repetition of similar errors instead of improved outcomes due to learning effects. Active interventions, however, were successful in improving CRS installation outcomes. Subjects who completed a practice installation with automated feedback from a display monitor were less likely to commit errors during a follow-up CRS installation compared to subjects who practiced without any feedback. The active educational system offers more critical learning steps necessary for acquiring new psychomotor skills compared to passive instruction resources. Thus, learning from step-by-step automated feedback may prove to be a powerful tool for the reduction of CRS misuse.
