    : This report provides an overview of the development, validation and reliability testing of the Canadian Problem Gambling Index, developed over the last three years. This research was conducted by a research team under the aegis of the Canadian Centre on Substance Abuse for the Inter-Provincial Task Force on Problem Gambling. The goal was to develop a new, more meaningful measure of problem gambling for use in general population surveys, one that included more indicators of the social and environmental context of gambling and problem gambling. The project was divided into two phases. Phase I was an examination of how problem gambling had been conceptualized, defined and measured in the literature, and the development or synthesis of a new conception, definition and means of measurement. This phase of the project involved an extensive review of the literature, and synthesis of the relevant literature into an integrated conceptual framework for our definition of problem gambling. The framework and the resulting definition were then put before a panel of experts in the field to ensure the new construct was adequately defined. After several rounds of consultation and feedback, a draft index based on the literature and feedback process was produced The second phase of this project was the fine tuning, validity and reliability testing of the index developed in Phase I. This was accomplished using a pilot test of 143 people, followed by a general population survey of 3,120 Canadian adults, a re-test (for reliability) of 417 respondents from the general population survey, and clinical validation interviews with 143 respondents who initially responded to the general population survey. The result of Phase II is a 31-item measure called the Canadian Problem Gambling Index. Nine of the items can be scored to produce a prevalence rate for problem gambling, and the remaining items are indicators of gambling involvement (types of gambling activity, frequency of play, spending on gambling), and correlates of problem gambling that can be used to develop profiles of different types of gamblers or problem gamblers. The prevalence rate for problem gambling produced by the CPGI falls between the rates obtained using the DSM-IV and the SOGS, much as anticipated. It does produce higher rates for those considered to be at risk, and this again was an anticipated result given the definition of problem gambling that directed the development of this index. Using the CPGI, survey respondents are divided into 5 groups: Non-gambling Non-problem gambling Low risk gambling Moderate risk gambling Problem gambling The prevalence rate for problem gambling obtained with the CPGI is roughly equivalent to the prevalence rate obtained using the DSM-IV in this survey. The CPGI goes one step further than most of the measures currently in use because of its relative emphasis on social and environmental factors related to problem gambling. This emphasis is reflected in both the composition of the nine scored items, and in the correlates that compose much of the rest of the index. We feel that it is this emphasis that has resulted in a larger proportion of the population being categorized as at low or moderate risk. In the past, prevalence surveys have used measures developed using clinical samples of problem gamblers, which are known to be demographically different than problem gamblers in general. Treatment program populations have traditionally under-represented women, ethnic minorities and individuals with lower socio-economic status than average. We feel that the inclusion of items addressing social and environmental context may have captured some of these typically under-represented populations. The inclusion of the correlates of problem gambling also allows for the development of profiles of specific types of problem gambling, using type of gambling activity and level of involvement as well as the correlates to develop a more detailed picture of those with problem or at risk levels of gambling.
