Review question
What are the effects of smartphone apps with game-like features on physical activity when used as a standalone strategy?
Background
Many individuals do not engage in recommended levels of physical activity, despite physical activity being shown to prevent disease and improve one’s health. Smartphone apps show promise in helping people get and stay physically active, but they need to be improved. Gamifying smartphone apps by incorporating features typically seen in games—such as point collection and challenges—is one strategy that could bolster their effectiveness. Currently, research on standalone gamified apps and their impact on physical activity is lacking.
How the review was done
This is a systematic review and meta-analysis of 19 studies, the majority of which were randomized controlled trials. The studies were published between 2014 and 2021 and included a total of 1,908 participants. Key features of the studies:
- Participants included children, adults, and older adults.
- Participants used standalone gamified apps for a period of 1 to 24 weeks.
- Researchers measured changes in physical activity levels and specific outcomes such as moderate-to-vigorous physical activity, walking and step counts.
- Outcomes were compared to control groups, which involved participants being placed on waiting lists to eventually participate in a gamified app intervention or engaging in/using some other standard strategy, such as lifestyle counselling, paper diaries, and calorie or activity tracking devices/apps.
What the researchers found
Overall, the review found that gamified apps may help increase physical activity levels, especially walking and step counts. Although leaderboards (that show users’ standings), rewards, and the integration of social networking were prominent features of the apps used in the included studies, more high-quality research is needed to understand which game-like features support and maintain behaviour change related to physical activity. These preliminary results were based on very low to moderate certainty evidence, meaning the results are likely to change as new studies emerge.
Conclusion
Smartphone apps which integrate game-like features may have the potential to increase physical activity levels, namely walking and step counts, when used as a standalone strategy.
