Effect of Pokémon Go on Self-Harm Using Population-Based Interrupted Time-Series Analysis: Quasi-Experimental Study

The launch of Pokémon Go functioned as a significant public health intervention, correlating with a measurable decline in self-harm incidence within the Hong Kong population. By employing an interrupted time-series analysis of hospital data spanning from 2012 to 2018, researchers identified a 34 percent reduction in self-harm attendances following the game’s introduction. This positive trend was most pronounced among adult populations and intensified during the later exposure period of 2017 and 2018, suggesting that the game’s influence on mental well-being grew as its community and mechanics matured.

The underlying mechanism for this improvement appears to be the game’s capacity to foster physical activity and social connectedness, which effectively replaces intrusive, self-harming thoughts with constructive, engaging experiences. While the study highlights these mental health benefits, it also notes a concurrent rise in common assault attendances, particularly among younger and older demographics, indicating that the game’s impact on public behavior is multifaceted. These findings suggest that augmented reality platforms possess the potential to serve as accessible, low-cost tools for enhancing psychosocial well-being.

Ultimately, the evidence supports the thesis that immersive digital experiences can act as a preventive measure against self-harm by encouraging healthier lifestyle habits and social integration. By bridging the gap between digital engagement and real-world interaction, such games offer a unique framework for supporting mental health at a population level. These conclusions underscore the importance of evaluating emerging technologies not merely as entertainment, but as significant variables in public health outcomes.
