The purpose of the study was to examine the gambling behavior among Vietnamese adults in Orange County, California. Specifically, this study assessed the extent of problem gambling and examined the relationships among gambling attitudes and self-perceived luck on gambling behavior among Vietnamese adults in Orange County, California. It was hypothesized that attitudes related to gambling or self-perceived luck would positively predict gambling behaviors. In addition, the combination of attitude and perceived luck were hypothesized to be a better predictor than either attitude or luck alone. Since data was not normally distributed, the results were not interpretable for the gambling prevalence rate among the Vietnamese population. Results indicated that there was a weak relation between attitude toward gambling (GAS) and gambling behavior using SOGS, but it was not strong enough to predict gambling behaviors, thus the null hypothesis was supported. Results indicated there was no relation between self-perceived luck and gambling behavior, thus the null hypothesis was supported. However, results indicated a relation between attitude towards lottery and self-perceived luck. Finally, results indicated there were no differences in results between taking the survey online or in person and in English or Vietnamese.
