An interventional study of Streak-based and Level-based in Children, sponsored by Palacky University. Recruiting at 1 site in Czechia. Open to participants aged 9 Years to 12 Years. Per ClinicalTrials.gov, last updated 2026-05-08.
Sponsored by Palacky University · Not applicable, Interventional, and Other
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.
371 studies on the registry are indexed under Behavior; 158 are open to participants now.
This study's planned enrollment of 160 is above the median of 120 across 295 interventional studies indexed under Behavior.

Does not meet one or more of the inclusion criteria Has a sibling already enrolled in the study
Participants receive financial rewards based on a points system, where completed target behaviors are converted into points. Accumulated points determine progression through predefined levels, which represent increasing achievement. Higher levels correspond to higher reward value.
Behavioral: Level-based
Participants receive financial rewards based on maintaining continuous engagement (streaks). Consecutive days of completing target behaviors unlock virtual equipment or items. Longer streaks result in more valuable rewards.
Behavioral: Streak-based
Participants receive financial rewards based on a combination of levels, and streak-based mechanics. Target behaviors generate points contributing to level progression, while sustained engagement additionally unlocks streaks. This arm integrates both accumulation and consistency-based incentives.
Behavioral: Combined: level and streak
Participants use the same mobile application with gamification features, but financial rewards are not linked to levels, or streaks. Rewards are provided only for completing questionnaires. The total potential reward value is equivalent across all arms.
Behavioral: Control
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.
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.
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.
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.
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
