Gambling is a popular recreational activity. It is widely accepted in Singapore. Cognitive distortions are beliefs and assumptions that are exaggerated or untrue. Cognitive distortions related to gambling are linked with problem gambling and gambling frequency. The researchers compared the cognitions of people who bet on sports and people who gambled but not on sports. A total of 713 participants were recruited in Singapore. This included 80 participants who bet on sports, 270 participants who gambled on other activities, and 363 participants who did not gamble. Participants completed the Gamblers Belief’s Questionnaire (GBQ) and the South Oaks Gambling Screen (SOGS). People who bet on sports had higher scores for Luck/Perseverance than those who did not gamble and those who gambled on other activities. People who bet on sports also scored higher on the Illusion of Control than people who did not gamble and those who gambled on other activities. In addition, participants who bet on sports were more likely to have problem gambling based on the SOGS.
