2 Page 2 INTRODUCING THE CANADIAN PROBLEM GAMBLING INDEX Harold J. Wynne, Ph.D. May 2002 BACKGROUND The development of the Canadian Problem Gambling Index (CPGI) was the result of a collaborative, three-year research venture ( ) managed by the Canadian Centre on Substance Abuse (CCSA) and funded by the Canadian provinces. The goal was to develop a new, more meaningful measure of problem gambling for use in general population surveys in Canada, one that reflected a more holistic view of gambling within a social and community context. The CPGI was developed as part of a larger research project entitled Measuring Problem Gambling in Canada. The Inter-Provincial Task Force on Problem Gambling was formed to guide the three-year study, and this group was comprised of government and agency representatives from across Canada (see Appendix 1 for a list of reps). The CCSA research team members included Dr. Harold Wynne, Jackie Ferris, Dr. Eric Single, and Dr. Nigel Turner and the following expert panel of Canadian and international gambling researchers advised the team at various stages of the project: Robert Ladouceur, Ph.D., Laval University, Quebec City Jeff Derevensky, Ph.D., McGill University, Montreal Rina Gupta, Ph.D., McGill University, Montreal Ron Frisch, Ph.D., University of Windsor, Ontario Sue Fisher, Ph.D., Cornwall, England Henry Lesieur, Ph.D., Pawtucket, Rhode Island Durand Jacobs, Ph.D., Loma Linda University, Redlands, California Randy Stinchfield, Ph.D., University of Minnesota, Minneapolis Ken Winters, Ph.D., University of Minnesota, Minneapolis Robert Wildman, Ph.D., Reno, Nevada Alex Blaszczynski, Ph.D. University of New South Wales, Sydney, Australia Michael Walker, Ph.D., University of New South Wales, Sydney, Australia The CPGI instrument resulted from (a) a review and synthesis of the most current gambling research available, and (b) expert opinion from internationally renowned gambling researchers, and it draws on the measures that have been used in the past for many of its key items. Consequently, the CPGI is less a new instrument and more an evolution of older measures, and it is based on the following operational definition of problem gambling developed by the research team: Problem gambling is gambling behaviour that creates negative consequences for the gambler, others in his or her social network, or for the community.
3 Page 3 METHODOLOGY The three-year Measuring Problem Gambling in Canada research project was conducted in two phases--a development phase and a testing phase. The development phase involved the clarification of the concept of problem gambling, the positing of an operational definition, and the designing of an instrument for measuring problem gambling in the general population. The second phase involved validity and reliability testing of the new instrument in a Canada-wide gambling prevalence study. The second phase of this project involved the fine-tuning, validity and reliability testing of the instrument developed in Phase I. This was accomplished by (a) conducting a pilot test of the face-valid instrument with 143 people; (b) following this pilot test with a general population survey of 3,120 Canadian adults; (c) re-testing 417 respondents from the general population survey, and (d) conducting clinical interviews with 148 respondents from the general population survey. The pilot test was conducted with three separate groups of about 50 persons each, intended to represent three potential sub-groups classified by the new instrument, namely: (1) a random, general population sample unlikely to have gambling problems (nonproblem gamblers); (2) a group of regular gamblers who may be at risk because of higher participation frequency and expenditure on gambling (at-risk gamblers); and (3) those who felt that they have a gambling problem at the severe end of the continuum (problem gamblers). This pilot test was used to determine if there were scored items from the facevalid instrument that did not discriminate between groups, and so could be eliminated in the next round of testing. Consequently, several items were deleted from the final survey instrument, but the South Oaks Gambling Screen (SOGS) and DSM-IV items were maintained in their entirety for comparative purposes. The final survey questionnaire, named the Canadian Problem Gambling Index, was administered to a random sample of 3,120 adults selected from the ten Canadian provinces. This large, general population survey was conducted for three main reasons. First, the large sample size allowed for fine-tuning the new instrument in terms of selecting items to be included/discarded in future iterations. Second, the survey provided a basis for comparison of the new instrument scored items with those from the DSM-IV and SOGS measures. Finally, the survey provided gambling/problem gambling prevalence information for the Nation and for individual Canadian provinces, and these data can be used as a benchmark for subsequent national or provincial studies. Although reliability can be assessed using a measure of internal consistency, and so could be calculated based solely on the general population survey, it was determined that a re-test of a small sub-sample from the general population survey would add to the rigor and credibility of the validation process. Consequently, a random sample of 417 respondents was re-called, and asked to complete the survey for a second time. Finally, to further test the validity of the new measure, clinical psychologists conducted telephone interviews with a sub-sample of 148 respondents from the general
4 Page 4 population survey. This was expected to provide confirmation of the classification scoring accuracy of the new instrument. CANADIAN PROBLEM GAMBLING INDEX The new instrument has been named the Canadian Problem Gambling Index (CPGI). The CPGI examines eighteen variables in four domains, and specific measurable indicators and corresponding questionnaire items are identified in Appendix 2. Domains of the CPGI Gambling involvement. The first CPGI section explores gambling involvement, with questions about (a) type of gambling activity, (b) the frequency of play, (c) duration of play, and (d) expenditure. The type of activity question is adjusted to suit the jurisdiction in which the CPGI is being used, and researchers are encouraged to identify as many gambling activities as are appropriate. These questions take very little time to administer, especially for those who participate in few gambling activities, which is the majority of respondents in a general population survey. Problem gambling assessment. The CPGI assesses two domains of problem gambling, namely (a) problem gambling behaviour, and (b) consequences of that behaviour for the individual or others. There are twelve items in these two domains, and nine of these are scored to determine problem gambling severity. This nine-item index is referred to as the Problem Gambling Severity Index (PGSI), and these items, along with the scoring algorithm, are included in Appendix 3. Depending on how a respondent scores on these nine PGSI items, he or she may be classified as being in one of four gambler sub-types, namely: (a) non-problem gambler, (b) low risk gambler, (c) moderate risk gambler, and (4) problem gambler (qualitative descriptions for each of these four sub-types are included in Appendix 4). Scoring the nine-item PGSI is crucial to the classification of gambler sub-types and, therefore, the PGSI items should not be removed or altered in any way. Correlates. The problem gambling correlates domain includes variables that further develop the profiles of gambler sub-types. Findings from the latest research in the field of gambling studies are reflected in these variables, and it is expected that new correlates will continue to be added by researchers. Reliability and Validity of the PGSI The psychometric properties of the Canadian Problem Gambling Index, including the nine-item Problem Gambling Severity Index, are described in detail in the Phase II report available on the Canadian Centre on Substance Abuse web site (www.ccsa.ca). A brief summary of the reliability and validity of the PGSI follows.
5 Page 5 Reliability. Reliability is the ability of a measuring instrument to give consistent results on repeated trials. The PGSI was subjected to two types of reliability testing; namely, internal consistency and repeated measures methods. First, the Cronbach alpha reliability coefficient was computed, which provided an indication of the internal consistency of the PGSI measure. The alpha coefficient for the PGSI (0.84) was stronger than that for either the SOGS (0.81) or DSM-IV (0.76). The reliability of three sub-components of the PGSI was also examined (i.e., the two items retained from the SOGS, the two from the DSM-IV, and the five new PGSI items). The two SOGS items (0.71), two DSM-IV items (0.79), and five PGSI items (0.80) correlated relatively highly with their parent measures, respectively, although they did not perform reliably as two or five-item stand-alone measures. The second method for examining reliability was to repeat the survey by retesting the same people on the same three measures. To establish re-test reliability, 417 of the original 3,120 respondents were re-surveyed, and the Pearson Product-Moment correlation coefficient for the three measures included in the survey was calculated. In terms of re-test reliability, the DSM-IV (0.91) was strongest over time, followed by the PGSI (0.78) and SOGS (0.75). From these tests, it is apparent that the nine-item PGSI is a reliable measure of problem gambling. Validity. The validity of the PGSI was addressed in terms of content (face) validity, criterion-referenced validity, and construct validity. Content validity is the degree to which a test measures an intended content area. In this vein, the original PGSI went through several rounds of expert feedback, with twelve of the world s foremost gambling experts providing advice on the most appropriate content needed to discriminate problem gambling (i.e., domains, variables, measurable indicators and items). The expert consensus was that the five PGSI problem gambling behaviour and four adverse consequence items appeared to measure both the construct and operational definition of problem gambling very well. Subsequent statistical factor analysis of the PGSI confirmed that the nine items in the index load on one factor, which the researchers naturally labeled problem gambling. Consequently, it may be concluded that the PGSI has very good content validity as a measure of problem gambling. Criterion-referenced validity generally refers to validity that is found by correlating a measure with an external criterion of the entity being assessed. There are two types of criterion-referenced validity concurrent validity and predictive validity. Concurrent validity refers to validity assessed by correlating a measure with an alternative measure of the same phenomenon taken at the same point in time. Predictive validity refers to the ability of a measure to predict some attribute or characteristic in the future.
6 Page 6 In the Canadian national survey, the nine-item PGSI, the twenty-item SOGS, and the ten-item DSM-IV measures were administered to each of the 3,120 adult respondents. The PGSI was shown to have good concurrent validity because its scores correlated highly with those from both the SOGS (0.83) and the DSM-IV (0.83). In terms of predictive validity, the PGSI (0.48) also had a higher correlation with the clinical assessment interview results than either of the other two measures, although the correlation is only moderate. In view of these findings, it may be concluded that the PGSI has strong concurrent validity with the SOGS and DSM-IV, and moderate predictive validity with clinical interviews. Finally, the validation study examined PGSI construct validity, which refers to the degree to which the measurement agrees with the theoretical concept being investigated. In terms of theory, one might expect that those in the problem gambling group would spend more money on gambling, gamble more frequently, and be more likely to endorse the problem gambling correlates. When trend analysis was conducted on the data, differences were apparent by gambler sub-type on almost all of these indicators and correlates. Those in the problem gambling group do spend more, gamble more often, and endorse most of the correlates at higher rates than those in the at-risk or non-problem groups. In view of this, it may be concluded that the PGSI is a valid measure of the construct labeled problem gambling. Classification Accuracy In the context of screening, there are two other measures of validity that must be considered, namely sensitivity and specificity. Sensitivity refers to the ability of the test to identify correctly all screened individuals who actually have the condition. In contrast, specificity refers to the ability of the test to identify only non-diseased individuals who actually do not have the condition. A main challenge in validating the PGSI was to set cut-points along the continuum of scores (i.e., from 0 to 27 points) to maximize both the sensitivity and specificity of the measure. It was important to ensure that those classified as problem gamblers according to PGSI scores were true positives for this condition; moreover, it was also important that the cut-point ideally captured everyone who was a problem gambler (sensitivity). Similarly, cut-points needed to be set to ensure that individuals who were not problem gamblers were identified as not having this condition (specificity). Typically in setting cut-points, there is a trade-off between maximizing sensitivity versus specificity, and this was the challenge in validating the PGSI. In the final analysis, the cut-point set to discriminate the problem gambling sub-group (PGSI 8) had relatively good sensitivity, as it successfully (a) identified seven out of nine (78%) individuals who were classified in the clinical interviews as being problem gamblers, and (b) identified 83% of the individuals who scored on the DSM-IV diagnostic measure as being pathological gamblers. Specificity was 100% for all measures, and this means that the people identified by the DSM-IV and SOGS as having no gambling problem were also categorized as having no problem by the PGSI.
7 Page 7 In determining the cut-point that discriminates low-risk from moderate-risk gambler sub-types (i.e., PGSI = 2 vs. 3), the distribution of DSM-IV and SOGS scores, along with clinical assessment interviews that differentiated those deemed to be at low versus moderate risk, were taken into account. Issues of specificity and sensitivity have little meaning when applied to these at-risk sub-groups, as individuals therein do not have the problem gambling condition, per se; rather, they are deemed to be at greater/lesser risk for developing a gambling problem. CONCLUDING COMMENT A tenet of public health is that primary prevention of disease and socio-health disorders such as problem gambling is the best approach. However, if these health conditions cannot be prevented, then the next best strategy is early detection in asymptomatic, apparently healthy individuals. To facilitate early detection, screening measures are typically employed, and the nine-item PGSI was developed as such a measure to detect individuals in the general population who have a gambling problem, or who are at risk for developing a problem. It should be noted that screening differs from diagnosis, which is the process of confirming an actual case of a disease or health condition. As a result of diagnosis, a treatment intervention may be initiated. Diagnostic tests are used to follow-up positive screening test results, or to concurrently screen for and diagnose a health condition. In screening for and diagnosing problem gambling, the gold standard measures have been the South Oaks Gambling Screen and DSM-IV, respectively. Interestingly, the SOGS has also been used in research and clinical interventions to diagnose problem gambling, notwithstanding that it was developed as a screening instrument. Similarly, the DSM-IV has been used in population surveys to screen individuals for a gambling problem, despite its primary purpose being to diagnose the mental health disorder labeled as pathological gambling. The utility of both the SOGS and DSM-IV for screening and/or diagnosing problem gambling has been debated at length in the gambling literature. Given that severe problem gambling is a fairly robust health disorder, the SOGS, DSM-IV, and other related measures have been generally successful in screening for the most seriously disordered. However, these measures have had far less utility for classifying individuals who have sub-clinical symptoms, or who may be at some level of risk for developing a gambling problem. Like these other measures, the nine-item PGSI successfully classifies those problem gamblers who are most severely disordered. However, unlike other measures, the PGSI has greater classification accuracy for successfully identifying individuals who are at low or moderate risk for developing a gambling problem. Moreover, given that the PGSI is part of the larger CPGI measure, there is much more information gathered about the at-risk and problem gamblers experience. This wealth of CPGI gambling-related information results in a much more detailed picture of the relationship between gambling
8 Page 8 activities, problem gambling behaviour, adverse consequences, and other problem gambling correlates. Future CPGI-based research. Since the Canadian Problem Gambling Index was published in 2001, it has been integral to a growing body of research in the gambling studies field. This ever-increasing use of the CPGI bodes well for (a) the future refinement of the instrument, including the PGSI sub-index, and (b) the development of a growing statistical database that includes directly comparable research results. The following are known instances where the CPGI has been utilized in recent gambling research projects: Canadian CPGI-based research 1. Doiron, J. & Nicki, R. (1999).

This gambling/problem gambling prevalence telephone survey was conducted in September 2001 with a random sample of 13,082 Queensland, Australia residents over 18 years-of-age. The researchers chose to use both the CPGI and SOGS to identify gambler sub-types, and a comparative analysis concluded that, the results show that all problem gambling respondents who have been captured by the CPGI were also captured by the SOGS. Findings and conclusions were subsequently
10 Page 10 reported based on the CPGI classifications. The researchers concluded, The CPGI provides important information about gambling groups in the population. Research is warranted to identify the common characteristics of the Low Risk, Moderate Risk and Problem Gambling groups which might identify those at most risk of developing problem gambling. 13.

This report outlines the findings of research conducted into the incidence of problem gambling within a random sample of 178 male and female prisoners incarcerated in Queensland, Australia corrective services facilities. The CPGI was used to classify gambler subtypes because, according to the Gambling Policy Directorate, the Canadian Problem Gaming Index (CPGI) was utilised by Treasury in its Queensland Household Gambling Survey 2001, and In addition, the CPGI s definition of problem gambling, as referred to in Section 1 of this report is analogous to that which is currently utilised for policy purposes in Queensland. 14. Linnet is conducting a study in Denmark with pathological gamblers in treatment, and a translated version of the PGSI is being used to discriminate gambler subtypes. 15. McMillen is working with two Australian state governments that are contemplating using the PGSI to screen problem gamblers for treatment.
