Fans watching live sport events, both mediated or in stadia, have witnessed an increase in sports betting products. Most of these products feature in-play betting, that is, the ability to bet on a game once it has started while watching it. In-play betting has raised many concerns among responsible gambling advocates due to its perceived relationship with problem gambling behaviour. This study explored the association between in-play betting and problem gambling. More specifically, the study examined how motives for consuming sport and how involved sports fans were in watching sport affected their gambling. Also, adjacent risk behaviours to in-play betting (such as consuming junk food and alcohol) during live sports betting were examined. Using a survey comprising 659 sports bettors from Spain, the study found that compared to participants not engaging in in-play betting, in-play bettors reported higher (i) problem gambling severity, (ii) sport watching involvement, (iii) consumption of sport to escape from everyday preoccupations, and (iv) consumption of junk food and/or alcohol while watching sport.These findings make the case that in-play betting regulators and providers should be cognizant of the interplay of sport-specific, media-related, and other risks, involved in the act of in-play betting while watching live sport.
