Problem gambling is a disorder that makes it difficult for people to resist impulses to engage in harmful gambling acts. Research shows that impulsivity, the tendency to act without thinking, is strongly related to problem gambling. Understanding what factors make up impulsivity can help explain and treat problem gambling behaviours. The UPPS-P Impulsive Behaviour scale assesses five factors that measure five distinct aspects of impulse behaviour: negative urgency, (lack of) premeditation, (lack of) perseverance, sensation seeking and positive urgency. This study explored how the five impulsivity factors from the UPPS-P Impulsive Behaviour Scale is linked to different gambling activities and which factors would best predict who may experience problem gambling in Australian adults.
