Psychometric properties of the Chinese version of the gambling related cognitions scale in Chinese mainland sample.

The English items of Gambling Related Cognitions Scale (GRCS) were first developed and validated by community-based population in 2004. The scale is now becoming a validated and reliable instrument to assess gambling related cognitions in the gambling literature of the West. The present study recruited 730 general adult Chinese individuals to validate the Chinese version of Gambling Related Cognitions Scale (GRCS-C). The results of a confirmatory factor analysis of the Chinese data supported the second-order model with five major factors proposed by Oei and Raylu (2006). The overall scale and five factors demonstrated satisfactory internal consistency and test-retest reliability. Construct validity and concurrent validity of GRCS-C was also sound suggesting that the GRCS-C is a valid and reliable instrument for assessing gambling related cognition among non-clinical Chinese individuals.
