Gambling in children and young people (CYP) can lead to many negative outcomes, such as financial consequences, psychological distress, and social difficulties. It also increases the risk of gambling-related harm in adulthood. There are interventions aimed at preventing or reducing gambling harm in CYP. Yet, systemic analysis of their effectiveness is limited. To address this gap, the researchers conducted a scoping review of studies published between 2008 and 2025. Studies had to involve interventions designed for CYP up to 25 years old. The analysis revealed four key themes: effective interventions often (1) integrate many methods and actively engage participants; (2) are theory-driven and delivered by trained practitioners; (3) are tailored to developmental needs; and (4) incorporate digital technologies.
