BACKGROUND: Gamification of behavioral intervention for tic disorders (TDs) potentially enhances compliance and offers key clinical advantages. By delivering immediate positive feedback upon tic-suppression, games may counteract negative reinforcement, which presumably contribute to tic consolidation by relieving uncomfortable premonitory urges.
OBJECTIVES: We developed a gamified protocol (XTics), which leverages this potential by combining gamified tic-triggering with immediate feedback, and evaluated its clinical value in enhancing tic suppression.
METHODS: XTics encompasses two conditions: Immediate and Contingent Reward (ICR), where game progression is contingent upon successful tic suppression, and Delayed Reward (DR), where game events' outcomes are random. Employing a randomized crossover design, 35 participants (aged 7-15 years) underwent daily gaming sessions over a week per condition. Improvements in our primary measures, including the inter-tic interval (ITI) and tic severity assessment by blinded evaluators (Yale Global Tic Severity-Total Tic Score [YGTSS-TTS], Rush), and parents (Parent Tic Questionnaire [PTQ]), were compared between ICR and DR, and assessed across conditions for the 4-week protocol.
RESULTS: No participant voluntarily left the study before completing its two-phase protocol. As expected, ITI showed significantly larger improvement (Z = 4.19, P = 2.85 × 10-5) after ICR (1442 ± 2250%) versus DR (242 ± 493%) training, increasing at a higher pace (t(67) = 3.15, P = 0.0025). Similarly, Rush tic severity scores reduced more post-ICR versus DR (t(47) = 3.47, P = 0.002). We observed a clinically significant reduction of 25.69 ± 23.39% in YGTSS-TTS following a f4-week protocol including both conditions. Parent-reported tic severity decreased by 42.99 ± 31.69% from baseline to 3 months post-treatment.
CONCLUSIONS: The combination of gamified tic-triggering with immediate and contingent rewards demonstrates a promising approach for enhancing treatment efficacy in TDs, boosting traditional therapeutic methods. © 2024 The Author(s).
