Gamification adds elements such as points, challenges, rewards, or a narrative to a research activity. The intention may be to make participation more engaging or encourage repeated responses. The design also changes the situation in which people answer, so its effect on the evidence needs examination.
An interactive control is not necessarily gamification. A well-designed form can reduce effort without introducing a game, and adding a game can sometimes create more work.
Ask what behaviour the reward encourages
In an illustrative diary study, awarding points for each completed entry may encourage participation. It could also encourage people to produce an entry when they have little to report, or focus on completing the activity rather than recording the experience carefully.
A 2024 experiment on game-based rewards in experience sampling found a trade-off between aspects of participation and response reliability in the procedure studied. It does not settle every use of gamification, but it shows why completion alone is an insufficient measure of success.
Specify the intended benefit and evaluate data quality alongside participation. The relevant checks depend on the study: missing answers, comprehension, consistency, substantive detail, or performance against an appropriate reference may all matter.
Preserve the meaning of the task
A prompt asking someone to imagine being a company’s chief executive may produce a different answer from asking about their own purchasing experience. That change can be useful for idea generation, but it should not be treated as equivalent measurement.
Likewise, a competitive ranking may encourage speed or socially desirable answers. Pilot the format with the intended audience, including people unfamiliar with the interaction and those with access needs. Questionnaire design still matters underneath the game.
Compare the whole experience
Where a format change is consequential, compare it with a suitable alternative and define what improvement would justify using it. Record whether the change affects who participates or which questions they answer.
Explain rewards and participation arrangements clearly, without making the game a source of pressure. A person should be able to stop in line with the study’s consent process.
The purpose is better research participation and evidence, not entertainment for its own sake. If a simpler reduction in survey fatigue addresses the problem, there may be little reason to introduce additional mechanics whose effects are harder to interpret.
