Comparing Game-Based Reward Systems to Support Children's Engagement:

May 5, 2026 updated by: Zdenek Svoboda, Palacky University

Effect of Gamification-Based Incentive Schemes on Behavioral Adherence in Children

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.

Design Details

  • Primary Purpose: Other
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Level-based
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.
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.
Experimental: Streak-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.
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.
Experimental: Combined Streak and level
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.
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.
Active Comparator: Control
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.
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Questionnaire adherence
Time Frame: 14 days

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
