Emerging adults aged 18 to 25 years are at higher risk of problem gambling. Thus, understanding the factors associated with problem gambling in emerging adults is important for developing approaches to reduce harm. This study looked at biopsychosocial factors associated with problem gambling in emerging adults studying at Irish universities. The researchers compared people with problem gambling and those with non-problem gambling. Problem gambling was defined as scoring 5 or higher on the Problem Gambling Severity Index (PGSI). Non-problem gambling was defined as scoring 0. The researchers found that being male, having an online gambling account, having a gambling app on one’s phone, and being impulsive are linked with problem gambling. Drinking a high volume of alcohol in a typical drinking session was also linked to problem gambling.
