Abstract: While substantial studies focus on risk and negative factors for problematic video gaming, the present study paid attention to protective and positive factors that lead to healthy gaming practice. Based on the self-determination theory (SDT), the present study investigated whether psychological needs satisfaction may facilitate players’ adherence to protective gaming beliefs and behaviors. With a survey among 737 video game players, Study 1 observed a positive association between psychological needs satisfaction and protective gaming beliefs and behaviors. Study 2 used the positive writing technique to promote players’ psychological needs satisfaction, and the players with enhanced autonomy and competence need satisfaction showed a higher adherence to protective gaming beliefs and behaviors. The findings imply that players’ autonomous motivation and self-perceived competence can play a role in healthy gaming practice. SDT-based healthy gaming strategies may help to develop practical and sustainable programs for containing problematic gaming and promoting players’ health and well-being.
