In this study, the researchers looked at the effects of gambling advertisements on sports betting intention and behaviour. The researchers recruited 1,334 adults living in France who gambled in the past year through Française des Jeux, an online gambling operator. Participants completed online questionnaires. They were then shown 10 different French sports betting advertisements that had run during the study period. For each advertisement, they were asked to recall whether they felt it had encouraged them to gamble and whether it had actually led them to gamble.
About 30% of participants felt that at least one advertisement had encouraged them to gamble, and about 22% actually placed a bet after seeing at least one of the advertisements. Younger age, more severe problem gambling, and difficulties with emotion regulation were consistently related to a higher likelihood of feeling encouraged to gamble and actual gambling after seeing an advertisement.
