Growing evidence for the efficacy of cognitive behavioral therapy for disordered gambling supports the need for a comprehensive set of gambling-related assessment measures with clinical utility. The Gamblers' Beliefs Questionnaire (GBQ) is a self-report measure that was used to identify gambling-related cognitive distortions (Steenbergh, Meyers, May, & Whelan, 2002). The GBQ is a brief measure with considerable psychometric strengths (e.g., Winfree, Ginley, Whelan, & Meyers, 2015). In this study, using a treatment-seeking and online sample, ROC analyses were performed to explore the diagnostic accuracy of the GBQ. The GBQ demonstrated good internal consistency and small but significant relations with diagnostic measures of disordered gambling. Sensitivity and specificity for a range of GBQ scores were examined and a clear clinical cut off score with a good balance of sensitivity and specificty was not identifed. Using only the online sample the measure demonstrated adequate sensitivity and specificity, and a preliminary GBQ cut off range of 70 to 80 was suggested. Further exploration of the GBQ's relation with diagnostic status with large, diverse, samples is recommended.
