Abstract
OBJECTIVE: Increased prevalence and penetration of cellphone and mobile Internet use have raised significant concerns about children's health and safety by offering new spaces for cyberbullying, harassment, and sexual misconduct. "Cyberhero Mobile Safety" is a videogame-based education program designed using tenets of the capacity model with the goal of instilling the knowledge and skills necessary to safely and productively navigate the mobile online environment. This study evaluates its usability, appeal, and perceived impact and usefulness. MATERIALS AND METHODS: Six educational videogames were part of a program delivered to 3rd-6th grade students (n=108) across six public schools in Upstate New York. Videogame play was electronically captured to evaluate usability. Likeability, acceptability, and perceived usefulness of videogame content were evaluated through postgame questionnaires. RESULTS: Videogame usability criteria were achieved on 82.7 percent of the students' gameplays. On a scale from 1 (low) to 5 (high), mean ratings were 4.09 (standard deviation [SD]=1.28) for likeability, 3.54 (SD=1.61) for acceptability, and 4.16 (SD=1.33) for perceived message usefulness. CONCLUSIONS: The "Cyberhero Mobile Safety" program is a feasible and potentially effective platform for delivering information about safe and healthy cellphone and Internet use to children. Results support the use of the capacity model to design educational videogames because games that aligned with theory principles were reported as having the most impact and being the most useful at shifting children's online behaviors. Future research should directly test the individual components of the capacity model to inform educational game design.
