About this trial

This Randomized Control Trial evaluates the impact of different gamification-based incentive schemes (levels, streaks and their combination) on adherence to target behaviors in children. Participants are randomized into four groups with different types of motivational frameworks.

Treatments tested in this trial

Streak-based
Behavioral
Participants use a mobile application with gamification elements. Daily completion of target behaviors maintains engagement streaks. Longer streaks unlock virtual items and higher-value financial rewards.
Level-based
Behavioral
Participants use a mobile application that incorporates gamification elements. Completing target behaviors within the app earns points, which contribute to progression through predefined levels. Advancement to higher levels results in higher financial rewards.
Combined: level and streak
Behavioral
Participants use a mobile application with gamification elements. Points earned from completing target behaviors contribute to level progression, while consecutive daily engagement unlocks streak-based rewards. Both mechanisms operate simultaneously to provide financial incentives for achievement and consistency.
Control
Behavioral
Participants use a mobile application that includes gamification elements (e.g., points, levels, or streak indicators) as part of the user interface. However, these in-app gamification features are not financially incentivized. Monetary rewards are determined by questionnaire compliance.

Trial outcomes

Primary outcomes

Questionnaire adherence

Participants are rewarded for completing study questionnaires using a combination of points, streaks, and level-based bonuses to encourage adherence and long-term engagement. 1. Base Reward (Questionnaire Completion) Participants receive points for completing questionnaires. Example: 60% completion 2. Streak System Participants earn additional rewards for consecutive questionnaire completion (daily or scheduled). Streaks are designed to reinforce consistent participation and habit formation. Streak: 22 CZK 3. Level System Participants progress through levels based on accumulated activity (e.g., completed questionnaires). Each level unlock provides a financial reward: 1 level = 450 CZK 4\. Combined Model (Levels + Streaks) A hybrid incentive structure can be applied: Streak reward: 10 CZK per streak milestone Level reward: 250 CZK per level achieved
