The purpose of this paper is to assess the effect of Ninja Kitchen, a food safety educational video game, on middle school students' food safety knowledge, psychographic characteristics, and usual and intended behaviors.
The experimental group (n=903) completed the following activities about one week apart from each other: pretest, played the game, posttest, and follow‐up test. The control group (n=365) completed the same activities at similar intervals but did not have access to the game until after the follow‐up test.
Linear mixed‐effects models, controlling for gender, grade, and geographic location revealed significant time by group effects for knowledge of safe cooking temperatures for animal proteins and danger zone hazard prevention, and usual produce washing behaviors. Pairwise comparisons, adjusted for multiple comparisons, indicated that after playing the game, the experimental group felt more susceptible to foodborne illness, had stronger attitudes toward the importance of handling food safely and handwashing, had greater confidence in their ability to practice safe food handling, and had greater intentions to practice handwashing and safe food handling. Teachers and students found the game highly acceptable.
The game has the potential to promote positive food safety behaviors among youth, in a fun and educational format.
