Balancing Fun and Function: Exploring Game Design Features for Long-Term Engagement in Anxiety-Relief Serious Games

Abstract

Anxiety disorders are one of the most common psychological disorders, yet many people who are experiencing anxiety-related symptoms often remain undetected and untreated. To address this issue, more accessible and engaging solutions, such as serious games, are needed. This thesis explores how psychological practices for treating anxiety can be integrated with game design features that promote replayability without compromising therapeutic value. Various established therapeutic methods and game design features have been explored in order to create an effective mobile prototype. The final prototype featured three mini-games based on breathing exercises, relaxation-based exercises, and attention bias modification. It also incorporated additional features such as an in-game store, a streak system, a scoreboard and more to enhance user engagement. A playtest with 22 people was conducted to evaluate the prototype’s effectiveness in reducing anxiety and promoting continued use. Results indicated a reduction in self-reported anxiety and stress levels, and high user interest in replaying the prototype. Feedback from the testers highlighted the importance of customisation, as responses to the mini-games varied depending on individual preferences. The findings suggest that customisation and a diverse range of therapeutic content are key to supporting both anxiety relief and user engagement. Further research is needed to assess the prototype’s long-term impact.
