Interaction Between Atypical Work Schedules and/or Idel Time at Work on At-risk Gambling Practices (PRAT-JEU)

Evaluation de l'Interaction Entre Les Horaires Atypiques et/ou Les Temps d'inactivité Sur Les Pratiques de Jeu à Risque Chez Les Adultes Travaillant Dans Ces Conditions

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.
