A concurrent mixed method approach was used to explore risk factors for problem gambling associated with instant ticket purchase gambling (ITPG) by Ontario baby boomers (BB). In Study 1, a purposive sample of gambling counsellors was interviewed. Questions were guided by Canadian Problem Gambling Index (CPGI) domains. Study 2 involved secondary analysis of CPGI data retrieved from the 2002 Canadian Community Health Survey 1.2 - Mental Health and Well-Being (CCHS 1.2). Three risk factors associated with ITPG were identified: additional gambling involvement, denial of gambling activity, and minimization of spending and financial consequences. Sampling bias in CCHS 1.2 gambling module precluded inferential testing. Available data revealed that ITPG involved 40% of BB in 2002, with at-risk/problem gambling prevalence 10.2%. Amongst problem gamblers, 75% pursued ITPG as one gambling activity. Based on these findings, the hypothesis that ITPG is a risk factor for development and maintenance of problem gambling was generated.
