Sponsored by Centre Hospitalier Universitaire de Nīmes · Observational
At-risk gambling causes individual and social harm, influenced by environmental, psychological, and socioeconomic factors. In France, 5% of adult gamblers show at-risk gambling practices. Atypical work schedules and idle time at work could increase this risk, but few studies have explored this. These working conditions impact the mental and cognitive health of workers, potentially contributing to at-risk gambling, especially during periods of idle time The study authors wish to explore the links between atypical work schedules, idle time at work, and at-risk gambling practices, considering social norms and individual vulnerabilities.
