Safe City: a Game-based Educational Approach to Promote Child Safety Knowledge and Behaviours

To evaluate the effectiveness of the Safe City game, a randomized controlled trial (RCT) following the CONSORT RCT guidelines will be conducted.The evaluation will therefore be conducted in four school districts. An invitation will be sent to each selected school. After the school principal agrees to join the trial, informed written consents will be obtained from parents of the participating students by our research staff before randomization. The participant recruitment and randomization process will be independently carried out by different research assistants. Outcome assessors will be blinded to the allocation of participants in each group.

All consenting student participants, before intervention, will be asked to complete a questionnaire on basic socio-demographics. The intervention will last 4 weeks. Their safety knowledge and behaviours, HRQOL and psychosocial difficulties will be assessed before and 1 and 3 months after the intervention.

Game ("intervention") group The Safe City game intervention uses a game-based learning approach to teach players how to recognize and remove injury hazards from different homes and sports areas. It also highlights the need to pay attention to traffic and safety facilities to prevent injuries in a real-world environment. Players will create their own avatar to assume the duties of safety inspectors in the game. Point, level and reward systems will be included to increase player motivation to engage in the game.

Participants assigned to the intervention group will be given a manual containing instructions to play the Safe City game. A research assistant will provide a briefing session on the game in each participating school. A unique username and password set will be created for each user to log in the game. This login information will be provided to the student participants in a sealed envelope after the briefing session. The participants will be instructed to play the game as many times as desired within a 4-week timeframe. The players ranked in the top 20 will receive a reward in the form of book coupon after the intervention ends.

Health education ("control") group All students in the health education group will receive a comprehensive package on safety information. The information package includes both printed and electronic promotional materials regarding safety and a comprehensive list of relevant website and information sources. The information from these relevant websites and information sources are similar to those used in setting the safety case scenarios for the Safe City game. As a result, both intervention arms will have comparable accessibility to safety-related information and the major contrast between the two groups will be the method of presentation (game-based learning vs traditional health promotion approach, i.e. unidirectional information package).
