The purpose of the present research was to determine the prevalence rate of gambling problems in senior citizens (55 years and older). A community-dwelling sample composed of 810 old adults living in the greater Montreal area in the Province of Quebec completed the Revised South Oaks Gambling Screen (SOGS-R). Results revealed that the 12-month prevalence rate was 1.2% for pathological gambling and 1.6% for at-risk gambling. Although, these rates are comparable to those reported elsewhere in Canada and in the US for senior citizens, the at-risk gambling rate was significantly higher than the current one for the general population of the overall Province of Quebec. Finally, a smaller portion of participants also completed two key items from the Gambling Passion Scale (GPS). Results revealed that obsessive passion was higher for pathological gamblers than for at-risk and non-problematic gamblers, while harmonious passion was lower for pathological gamblers than for at-risk and non-problematic gamblers.
