Drawing on the social capital theory, the present study investigated the mediating role of online social capital on the relationship between in-game social interaction and POG, and the moderating role of alienation on the relationship between online social capital and POG. Methods: A sample of 457 Chinese MMORPG gamers was recruited to complete the In-Game Social Interaction Questionnaire, Online Social Capital Scale, Alienation Scale and Pathological-Gaming Scale. Results: The results showed online social capital was a mediator in the relationship between in-game social interaction and POG. Moreover, for individuals with low alienation, the effect of online social capital on POG was weaker than for those with high alienation. Conclusions: The present study provides new insight into the complex processes involved in the effect of in-game social interaction on POG, and the results have important theoretical and practical implications.
