INTRODUCTION Understanding the correlates of problematic gambling among emerging adult university students is crucial for developing effective approaches to minimise harm.

METHODS This cross-sectional survey study reports on 397 18-25 year old emerging adults studying at Irish universities who completed an online survey about problematic gambling and a range of biopsychosocial variables. Chi-square and binary logistic regression analyses explored the relationships between problematic gambling and the biopsychosocial variables measured.

RESULTS Chi-square analyses showed that being male, having an online gambling account, having a mobile gambling app, novelty seeking (impulsivity), harm avoidance (fear of uncertainty), and high alcohol volume consumption were significantly associated with problematic gambling. Regression analyses showed that individuals were more likely to report problematic gambling if they were male (OR = 9.57 times), had an online gambling account (OR = 17.05 times), had a mobile gambling app (OR = 20.37 times), scored high in impulsivity (OR = 7.79 times), and reported high alcohol volume consumption (OR = 4.66 times). Individuals were less likely to report problematic gambling if they scored high in fear of uncertainty (OR = 0.26 times).

CONCLUSIONS A high rate of problematic gambling was observed among the current study sample. Participants were more likely to reported problematic gambling if they were male, had online gambling accounts, mobile gambling apps, scored high in impulsivity, scored low in fear of uncertainty, or consumed high volumes of alcohol in typical drinking sessions. These findings have implications for Irish legislation and policy-makers, Irish higher education institutions, and young adult Irish university students.
