Development and Evaluation of A Game-Based Mobile App for Increasing Physical Activity in Autistic Adults

The clinical study aims to develop and test a gamified mobile health app called PuzzleWalk (PW) to promote physical activity (PA) and reduce sedentary behavior (SB) in autistic adults, including those with mild intellectual disabilities (ID). The study addresses the need for tailored interventions in this population, who are at higher risk for lifestyle-related chronic health conditions due to lower PA and higher SB. The upgraded version of PuzzleWalk integrates behavior change techniques and gamification strategies, such as translating step counts into puzzle game playtime, to encourage regular PA and reduce SB. The study will evaluate the app's effectiveness on preventive health behavior changes in real-world settings. The ultimate goal is to create an effective, sustainable, and scientifically validated mobile health tool to improve the health and well-being of autistic adults.
