Background: Unintentional injuries are the leading cause of death for children >1.1 Mobile technologies offer a largely untapped strategy to communicate with parents about prevention.2 We describe the development, implementation, and evaluation of Safety in SecondsTM (SIS), a mobile app that communicates safety information on car seats and fire and burn injuries.
Methods: We used the Precaution Adoption Process Model to develop the SISTM mobile app, and tested it in an RCT conducted in emergency departments of one urban and one rural level 1 pediatric trauma center. A total of 742 parents with children younger than 7 years participated. One group was randomly assigned to receive car seat messages and one received fire prevention messages. Outcomes are self-reported behaviors at a 6-month follow-up.
Results. We developed a template to create the message library and algorithm that delivered stage-tailored content targeting parents' self-efficacy, social influence, risk perceptions, barriers, and reinforcement. At 6 months, there were statistically significant effects for reporting use of the correct car seat (O.R. 1.836, p<0.01), and having the car seat inspected (O.R. 1.730, p<0.01) (see Table). Results on fire safety behaviors are currently being analyzed, and will also be presented.
Conclusions. The delivery of individually-tailored persuasive messages to large populations is possible with computer technology. Our results suggest that this approach holds promise to promote injury prevention.
