The Impact of Video Gaming on Mental Well-being: A Study in Japan

The widespread use of video games has sparked significant debate over their potential effects on mental well-being. Concerns about the negative impact of prolonged gaming have been raised, particularly in light of the increasing number of people engaging in this activity during the COVID-19 pandemic. However, empirical evidence on the subject has often been limited to correlational studies, leaving the causal relationship between video gaming and mental well-being unclear. To address this gap, a study was conducted in Japan from 2020 to 2022, using a natural experiment involving game console lotteries to explore the causal effects of video gaming on mental well-being.

The study’s design leveraged the random nature of these lotteries, which were held to allocate limited gaming consoles such as the Nintendo Switch and PlayStation 5. The random distribution of these consoles allowed researchers to observe the effects of gaming on individuals who won the lottery and compare them with those who did not. This approach provided a unique opportunity to move beyond simple associations and draw more definitive conclusions about causality.

Participants in the study were surveyed about their gaming habits, mental health, and life satisfaction. The survey data was analyzed using various statistical methods, including multivariate regression, propensity score matching (PSM), and an instrumental variable (IV) approach. The results revealed that ownership of a gaming console and increased gaming time had a positive impact on mental well-being, particularly in reducing psychological distress and improving life satisfaction.

One of the key findings was that winning a game console lottery reduced psychological distress by approximately 0.2 standard deviations for the Nintendo Switch and around 0.1 standard deviations for the PlayStation 5. Additionally, winning a PS5 lottery enhanced life satisfaction by about 0.2 standard deviations. These findings suggest that video gaming can have a beneficial effect on mental well-being, contrary to the often negative public perception of gaming.

Further analysis using a causal forest machine learning algorithm indicated that the impact of gaming varied among different demographic groups. For instance, the benefits of owning a Switch were more pronounced among younger individuals, while the PS5 showed larger benefits for males and those without children. This divergence highlights the complexity of the relationship between video gaming and mental well-being, suggesting that different types of gaming platforms may affect users in distinct ways.

Moreover, the study found that the duration of gaming played a crucial role in determining its impact on mental well-being. While moderate gaming had positive effects, playing video games for more than three hours a day was associated with diminishing psychological benefits. This finding underscores the importance of balancing gaming with other activities to maximize its potential benefits.

In conclusion, the study provides robust evidence that video gaming can positively influence mental well-being, particularly when gaming is done in moderation. The use of natural experiments and advanced statistical methods allowed researchers to draw more definitive conclusions about the causal relationship between video gaming and mental health. However, the study also highlights the need for further research to explore the mechanisms behind these effects and to understand how different types of gaming platforms and user demographics influence the outcomes.
