The Role of Videogame Micro-Transactions in the Relationship Between Motivations, Problem Gaming, and Problem Gambling.

Emerging research has highlighted potential associations between micro-transaction use and problematic videogame and gambling behaviour. An increasingly prominent theory highlights that self-determined motivations and basic psychological needs may play crucial roles in the development of problematic videogame and gambling behaviour. However, literature discussing the role that micro-transaction use has in this relationship is scarce. The present study examined the role of micro-transactions in the relationship between self-determined motivations for gaming and gambling and problematic behaviour (internet gaming disorder and problem gambling severity). A sample of 370 participants (74.1% male, M_age = 28.24 years, SD = 7.88) answered questions related to their gaming and gambling motivations, basic psychological needs, micro-transaction use (i.e., type of micro-transaction, expenditure, and frequency of use), internet gaming disorder, and problem gambling. The present study used structural equation modelling methods to test relationships between these variables. The results indicated positive associations between extrinsic gaming and gambling motivations and frequency of micro-transaction use. Frequency of micro-transaction use (i) partially mediated the relationship between extrinsic gambling motivations and problem gambling severity, and (ii) fully mediated the relationship between externally regulated gaming motivations and problem gambling severity. Expenditure on micro-transactions and basic psychological needs were not found to be significant variables in the present study. Potential explanations for the findings, including a lack of self-esteem and a need to boost ego, social pressure, and rapid reward processes, are discussed. The implications and applications of the research are also discussed, focusing on limit setting and policy development focusing on frequency of micro-transaction use.
