Gambling and gaming have been linked to traits associated with risk-taking, including risky decision-making and behaviours that favour risk. Traits such as sensation-seeking, impulsivity, and low self-control have been linked to gambling behaviour. Individuals exhibiting sensation-seeking characteristics tend to favour diverse and stimulating experiences, demonstrating a readiness to take risks in pursuit of these encounters. Consequently, this may result in diminished mental and social well-being. The study investigates the effects of behavioural addictions on mental health, particularly concentrating on gambling and gaming. The study utilised a qualitative research design, selecting one hundred and fifty youths in Ado Ekiti, Ekiti State through purposive and convenience sampling methods. The questionnaires included sections on socio-demographics as well as scales measuring gambling addiction, social health, and mental health. Descriptive statistics and regression analysis were utilised. The study's findings indicated a positive correlation between the severity of behavioural addictions and the extent of negative mental health outcomes, including diminished emotional well-being and compromised interpersonal relationships. Educational institutions, community centers, and mental health organisations should launch awareness campaigns aimed at informing youth, parents, and educators about the dangers of behavioural addictions (such as gambling and gaming) and their effects on mental health.
