Introduction: Skipping breakfast may contribute to poor academic and nutritional status among school children. The current study aimed to determine the effect of the ‘MAPAGI’ (Makan Pagi Bergizi) interactive video game on elementary student’s breakfast knowledge and attitude. Methods: This was a quasi-experimental equivalent group study with a pre-post test control group design. In total, 228 students aged 9-11 years were drawn by proportional stratified random sampling from two urban schools and were distributed equally into intervention (IG) and control groups (CG). Both groups were administered with similar printed media for 10-15 minutes. Video game was delivered only to IG for two consecutive days, 30 minutes each day. Pre-test (PT0) was performed a day before leaflet administration, while post-test was performed twice – after leaflet administration (post-test 1/ PT1) and a week after the last video game (post-test 2/PT2). Paired, independent t-test and analysis of covariance (ANCOVA) were employed to answer the research questions. Results: The mean changes (PT1-PT0 and PT2-PT0) in knowledge score for IG (4.82±2.53 and 3.25±2.47) significantly differed compared to CG (1.75±2.66 and 1.25±2.69). The mean changes in attitude score for IG (7.16±7.17 and 7.34±7.11) also significantly differed compared to CG (2.83±6.58 and 2.64±6.90). After adjustment for potential confounding factors, there was still a significantly greater score in children’s knowledge and attitude after a week’s administration of MAPAGI video game in IG. Conclusion: ‘MAPAGI’ improved school children’s knowledge and attitude, which may lead to the good behaviour of having breakfast.
