Motor vehicle collisions are among the leading causes of unintended injury-related deaths among children under the age of 14. The primary cause of these deaths is the improper use of child passenger safety restraints (CPSRs). Correctly installed CPSRs can decrease the risk of fatal injury by 45% to 95%. To date, no studies have used video prompting with embedded safety checks to teach correct CPSR installation and harnessing in the absence of researcher-delivered instruction and feedback. We used a concurrent multiple-baseline-across-participants design to evaluate the efficacy of a video-prompting procedure with embedded safety checks to teach four prospective parents and caregivers CPSR installation and harnessing skills. All participants learned to perform these skills, and these effects maintained for 4 weeks. Furthermore, this training improved all participants' performance of an untrained installation position, vehicle, and harnessing skill, and these effects were largely maintained for 4 weeks.
