Gambling expectancies have been reported to be an important variable in adolescents' gambling behaviours. However, little is known regarding the role of gambling expectancies among Chinese adolescents. This study aimed to identify Chinese adolescents' expectancies for gambling and to evaluate their relation to gambling behaviours. Exploratory and confirmatory factor analyses were performed which confirmed that a five-factor model was a good fit for the data. The five factors – namely, social benefits, relational costs, material gain, being out of control, and money loss – were revealed. The findings demonstrate the importance of understanding gambling behaviours within specific cultural contexts.
