Game Effectiveness for Enduring Lifestyle Change and Better Health
Serious digital games can successfully promote healthy lifestyle change1,2. For example, an analysis of 54 studies of health-promoting serious games found that lifestyles improved significantly from playing the games* as did clinical outcomes**.2 The games that are most effective at producing healthy change have a sound theoretical foundation in behavioral change and effective game design.2 Merging the immersive, attention-maintaining properties of stories and fantasy, the engaging properties of interactivity, and behavior-change principles, such as tailored messages and goal setting, contributes to game effectiveness.
Game Design for Lifestyle Change
The following components are effective at producing healthy lifestyle change in games for obesity management and prevention:
- Provide a foundation of knowledge and skill for behavior change.3
- Encourage personal mastery and offer avatars to personalize the experience.3
- Demonstrate the desired change for observational learning.3
- Have players make a personal plan for changing their behavior.4
- Make the game fun! This key element includes dramatic tension, humor, and challenge.3
- Emphasize increasing desired behavior over decreasing poor behavior, because changing the latter is more difficult to achieve.2
Combining these components increases the likelihood a game will support healthy lifestyle change.
Tailoring the game experience to the player is another key element to engage them in making a healthy change in their lives. Making the game adjust to personal information the player enters attracts their attention and supports their information processing. Serious game experiences should be tailored according to:
- The player’s specific need for lifestyle change1,2
- The player’s game skills1,2
- The player’s preference1,2
A game that presents messages to the player according to personal information entered or personal goals set before playing is an example of tailoring.3 A food selection game that allows the player to set the game’s challenges and rewards according to foods eaten in specific dietary plans, such as low-carbohydrate or the Dash diet, is another example.
