OBJECTIVE: To assess gambling behaviours and the problems associated with pathological gambling among the adult population of Quebec in 2002. METHOD: In Phase 1 of this 2-phase study, a total sample of 8842 adults was assessed. We used the South Oaks Gambling Screen (SOGS), adapted for telephone interview, to assess one-half of the sample; the other one-half was evaluated with the Canadian Problem Gambling Index (CPGI). In the study's second phase, we compared the classifications obtained from these screening instruments with classifications obtained by a psychologist using a semistructured clinical telephone interview. RESULTS: The results indicate that the prevalence of pathological gambling in 2002 (at which time 0.8% of the adult population were classified as probable pathological gamblers) did not differ from the proportion obtained in 1996 (1.0%), despite the significant decrease in gambling participation in 2002 (81% vs 90% in 1996). The most popular gambling activities were buying lottery tickets (68%), participating in fundraising draws (40%), gambling in casinos (18%), playing cards with family or with friends (10%), playing bingo (9%), and playing video lotteries (8%). The findings obtained from the SOGS and the CPGI revealed that the 2 instruments perform similarly when identifying pathological gambling prevalence. However, the results of the semistructured clinical telephone interviews differed from the results obtained with the screening instruments: 82% of the gamblers initially identified as probable pathological gamblers by the SOGS or the CPGI were not confirmed by a clinical interview. CONCLUSION: The discrepancy between the results of the screening questionnaires and the clinical evaluation is significant, and this difference needs to be addressed before further cross-sectional or longitudinal studies are conducted.
