Performance and Enhancement of the Canadian Problem Gambling Index (CPGI): Report and Recommendations

Abstract

In February 2001, a newly developed instrument was launched to measure the prevalence of gambling and problem gambling in the general population. The Canadian Problem Gambling Index (CPGI), introduced under the aegis of the Canadian Centre on Substance Abuse (CCSA) on behalf of a consortium of provincial funding resources, was developed to provide a more accurate measure than other available instruments. The CPGI was validated with a general population sample, unlike other instruments (e.g. SOGS and DSM-IV) that were constructed using clinical samples of problem gamblers. As a result, the CPGI provides greater distinction among gambling sub-types, and contributes to our understanding of the distribution from low-risk to problem gambling. Since its launch, the CPGI has been used in all ten Canadian provinces, and in Australia (Queensland, Victoria, and Tasmania), Norway and Iceland. In addition, it has been included in the national Canadian Community Health Survey – Mental Health and Well-Being. Although not the focus of this review, the CPGI has been used for purposes other than population prevalence studies, including as a clinical intake instrument and in a range of research initiatives. In the process of using the CPGI, several principal investigators have gained substantial experience in the use of the CPGI. The Funding Partners anticipated that this researcher base would provide valuable feedback on the instrument’s performance in meetings its objectives, and would provide a strong basis for refining the instrument.
