Winning Exposure and Positive Illusions Among Chinese Lottery Gamblers: Moderating Effects of Lottery Winning Experience and Socioeconomic Status.

Positive illusions and winning exposure are key factors leading to problem lottery gambling, but few studies have examined the relationships between them. 402 Chinese lottery gamblers was conducted with the Winning Exposure Questionnaire, the Positive illusion Questionnaire, the Winning Experience Questionnaire, and the Social and Economic Status Questionnaire to investigate the relationship between winning exposure and positive illusions as well as the moderating role of winning experience and socioeconomic status. The results showed that winning exposure can significantly and positively predict the positive illusions (optimism bias, better than average bias, and illusion of control) of lottery gamblers. The highest winning amount and subjective socioeconomic status significantly moderated the relationship between winning exposure and optimism bias. That was to say, for lottery gamblers with smaller maximum winning amount and lower subjective socioeconomic status, the association between winning exposure and optimism bias was stronger. Furthermore, the moderating effect of highest winning amount in the relationship between winning exposure and better than average bias, and the moderating effects of occupational status and subjective socioeconomic status in the relationship between winning exposure and illusion of control were marginally significant.
