title: Adaptation study of the Turkish version of the Gambling-Related Cognitions Scale (GRCS-T).
abstract: This study aimed to adapt and to test the validity and the reliability of the Turkish version of the Gambling-Related Cognitions Scale (GRCS-T) that was developed by Raylu and Oei (Addiction 99(6):757-769, 2004a). The significance of erroneous cognitions in the development and the maintenance of gambling problems, the importance of promoting gambling research in different cultures, and the limited information about the gambling individuals in Turkey due to limited gambling research interest inspired the present study. The sample consisted of 354 voluntary male participants who were above age 17 and betting on sports and horse races selected through convenience sampling in betting terminals. The results of the confirmatory factor analysis following the original scale's five factor structure indicated a good fit for the data. The analyses were carried out with 21 items due to relatively inadequate psychometric properties of two GRCS-T items. Correlational analyses and group comparison tests supported the concurrent and the criterion validity of the GRCS-T. Cronbach's alpha coefficient for the whole scale was 0.84 whereas the coefficients ranged between 0.52 and 0.78 for the subscales of GRCS-T. The findings suggesting that GRCS-T is a valid and reliable instrument to identify gambling cognitions in Turkish samples are discussed considering the possible influence of the sample make-up and cultural texture within the limitations of the present study and in the light of the relevant literature.
