Estimating the extent and degree of Gambling related problems in the Australian population: A national survey

A stratified random doorknock method was used to interview 2744 respondents in four state capitals in Australia. The interview was in 3 parts with the latter two only administered to regular, once per week or more often gamblers (N=290). The measures completed by this group included the South Oaks Gambling Screen and a range of psychological measures. A conservative interpretation of the results was that “problem gamblers,” defined in terms of a range of personal and interpersonal gambling-related costs, comprised 1.16% (±0.34%) of the Australian population. It was estimated that problem players’ losses may account for about one quarter of all expenditures on gambling.
