This study applied the Theory of Planned Behaviour to understand factors that influenced gamblers’ use of strategies to stay within their gambling limits. A total of 411 Australian gamblers completed an initial online survey with a follow-up 30 days later. The results showed that 92% of the gamblers used at least one strategy over the 30-day period. Gamblers who had positive attitudes towards the use of strategies and believed that they had control over their use had greater intention to do so. In turn, intention predicted actual use of strategies. Unexpectedly, how others in one’s social network judged the use of strategies did not influence intention.
