Validation of Gambling Related Cognitions Scale-Iranian Version (GRCS-IR)

The change in gambling forms, a wide variety of advertising methods, the access to gambling, as well as the increase in participation in online gambling have made it important to know and investigate gambling, particularly as pathological gambling leads to psychological and physical damage. The present study investigated the factor structure of the Gambling Related Cognitions Scale (GRCS) proposed by Raylu and Oei in addiction. The study sample included 574 participants (40.2% male, 59.8% female) between 18 and 56 years of age. The instruments used in the present study included the GRCS, the South Oaks Gambling Screen Questionnaire (SOGS), the Victorian Gambling Screen (VGS), and the Problem Gambling Severity Index (PGSI).  A 5-factor GRCS model provided the best fit to the data, and gambling-related cognitions were a strong predictor of disordered gambling among adults. All subscales presented good internal consistency and scalability. The findings showed that the total score of the GRCS-IR was significantly different among men and women. The findings of this study confirmed that the Iranian version of the GRCS-IR is an effective multidimensional instrument that accurately measures cognitive distortions related to gambling. Consequently, it can be utilized as a valuable tool for assessing GRC (Gambling Related Cognitions) to understand the severity of pathological gambling and has the potential capacity to measure treatment outcomes.
