“…No evaluation has yet been done of the French general population; however, it can be hypothesized that the prevalence of pG in France is in the range of prevalence reported in other developed countries, from 0.5% in Switzerland (Bondolfi et al, 2008) to 2.6% in Canada (Cox et al, 2004). Thus, the prevalence of pG is about three times higher in patients with addiction disorders than in the general population, a feature already reported elsewhere (Toneatto and Brennan, 2002;Weinstock et al, 2006). There are only a few standardized questionnaires designed to identify pG, the best known being the SOGS (Lesieur and Blume, 1987), the DSM IV-TR diagnostic criteria of pG (Stinchfield et al, 2005), the problem gambling severity index (Holtgraves, 2009) and the DEBA test; all have been validated although some reports have pointed out that they need some improvement (Holtgraves, 2009;Stinchfield, 2002;Stinchfield et al, 2005).…”
