This rapid review explored the influence of family on gambling. A total of 36 studies published between 2018 and 2024 were examined. The findings revealed that family significantly impacts gambling behaviours through two aspects: family environment in childhood and family environment in adulthood. Gambling might become normalized within the family and increase the risk for harm. This risk is also influenced by family characteristics such as parental relationship, household income, and domestic violence. Family can also mitigate gambling-related harm, and involving family in therapy can be beneficial.
