Across two studies we assessed the clinical utility of the Canadian Problem Gambling Index (CPGI). In Study 1, the scored items on the CPGI significantly correlated with those of the South Oaks Gambling Screen (SOGS), yet their shared variance was low. Importantly, clinician evaluation of the client's level of pathology was more strongly associated with that revealed by the CPGI than the SOGS. In terms of utility, clinicians found the non-scored items on the CPGI more useful in treatment than those included with the SOGS. In Study 2, the effectiveness of the CPGI profiler (CPGI-P) software, which graphically depicts problematic gambling-relevant attitudes and behaviours, was assessed. Although clients had difficulties using the CPGI-P interface, they overwhelmingly indicated that the output prompted action to address their gambling. The clinicians were less enthusiastic as they felt the output did not help clients truly understand their gambling problems. Such sentiments were reiterated by the clinicians at a 6 months follow-up. The use of the SOGS and possible adoption of the CPGI (as well as the CPGI-P) in a clinical setting are discussed.
