Life history (LH) strategies have been used to explain individual differences in personality traits and behaviours, such as risk-taking. This study aimed to extend previous research on LH strategies. It examined the links between LH strategies, protective gambling beliefs, and responsible gambling behaviours. A total of 697 Chinese adults living in Macao participated in a telephone survey. Overall, people with slower LH strategies reported more protective gambling beliefs and responsible gambling behaviours. Protective gambling beliefs partially explained the relationship between LH strategies and responsible gambling behaviours. People with slower LH strategies were more likely to endorse protective gambling beliefs. This, in turn, helped to foster responsible gambling behaviours.
