“…Some behavioural characteristics that were used to diagnose/identify problem gambler, including chasing losses or increasing bet sizes (American Psychiatric Association, 2000;Ferris & Wynne, 2001;Lesieur & Blume, 1987), can be monitored in a manner that is more reliable than past research tools such as survey self-report data (Hodgins & Makarchuk, 2003;Volberg, Gerstein, Christiansen, & Baldridge, 2001). Osborn, Skelt, Delfabbro, Nevile, and McMillen (2007) and Schellinck and Schrans (2007) conducted major empirical studies that examined observable signs of problem gambling in gaming venues.…”
