Exploring relationships between problem gambling, scratch card gambling, and individual differences in thinking style

Abstract

Background and aims Scratch cards are a popular form of lottery gambling available in many jurisdictions. However, there is a paucity of research that examines associations between individual differences in thinking style, participation in scratch card gambling, and problem gambling severity. Methods In three studies, we sought to examine the relationships among these variables in large, online samples of participants. Participants completed the Cognitive Reflection Test (CRT), the Problem Gambling Severity Index (PGSI), the Actively Open-Minded Thinking Scale, and self-reported their frequency of scratch card gambling. Results Throughout all three studies, specific associations were reliably established. Specifically, negative associations were observed between participants’ CRT and PGSI scores, as well as between participants’ CRT scores and scratch card gambling frequency. In addition, we found a positive association between problem gambling severity and scratch card gambling frequency. Finally, problem gambling severity was shown to correlate positively with participants’ willingness to pay for irrelevant information in a scratch card gambling scenario. Discussion and conclusions Overall, we observed that problem gambling severity is associated with an individuals’ thinking style and scratch card gambling behavior. This study adds to the existing literature examining problem gambling, and highlights the role of thinking style in understanding gambling behavior and problematic gambling.
