In 2001, a new instrument was launched to measure the prevalence of gambling and problem gambling in the general population. The Canadian Problem Gambling Index (CPGI) was introduced by CCSA on behalf of a consortium of provinces. By including indicators of social context and degrees of problem severity, CPGI provides a more complete view of gambling than earlier instruments (e.g., SOGS and DSM-IV). Since its launch six years ago, CPGI has been used in all Canadian provinces and in several other jurisdictions, including Australia, Norway and Iceland. As a result, a number of researchers have gained significant experience and insight in the use of CPGI. This experience was captured in a recent study conducted by McCready et al., making recommendations for the enhancement of CPGI. The interprovincial consortium also funded a review by Brown et al. to examine critiques of CPGI and secondary analyses of data emanating from existing surveys. The result of these efforts is a staged plan for the refinement of CPGI over an 18-month period.
