Previous research has suggested that gambling influences financial stress. Financial stress is the difficulty faced by an individual or a household in meeting basic financial commitments due to a shortage of money. This study examined the link between individual problem gambling severity and financial stress among Australians. The researchers used responses from Australians aged 15 and older who completed the Household, Income and Labour Dynamics in Australia (HILDA) Survey in 2015 or 2018. The results showed that greater problem gambling severity was linked to greater financial stress. Men reported more gambling problems, but women reported more financial stress. Playing scratch cards and poker machines mainly account for the greater financial stress. A person’s financial resilience could help protect them against the effects of gambling on financial stress.
