Abstract
Microtransactions provide optional, virtual, video game goods that, for an additional cost to the player, provide additional game content and alter the gameplay experience. Loot boxes-a specific form of microtransaction-offer randomised rewards in exchange for payment, and are argued to be structurally and psychologically similar to gambling. Nascent research suggests that a link exists between autism and both problematic gaming and problematic gambling. Here, we investigated the relationships between autistic characteristics and experiences, and excessive video gaming and microtransaction expenditure. A sample of 1178 adults from Australia, Aotearoa, and The United States were recruited from Prolific Academic, and completed a survey measuring in-game expenditure, autistic characteristics and experiences, problematic gaming, problematic gambling, and risky loot box use. Analyses showed positive associations between autistic characteristics and experiences with problematic gaming and problem gambling symptomatology. However, results also showed a small, negative association between autistic characteristics and experiences and spending on loot boxes when problem gambling symptoms, problematic gaming, and risky loot box use were statistically controlled for. These results suggest that autistic gamers may be vulnerable to problematic gaming and gambling, but that this effect does not extend to the purchasing of microtransactions.
