摘要:The purpose of this study was twofold: (a) to examine the actual circumstances of involvement in gambling, and (b) to investigate the relationships between levels of the gambling problem and the Big Five personality traits among Japanese adults. Nine hundred Japanese adults were asked to complete a web-based questionnaire to measure their levels of involvement in gambling and personality traits. The results indicated that approximately 47% of the participants had engaged in gambling before. In addition, a positive relationship was observed between levels of gambling involvement and Neuroticism, while Agreeableness and Conscientiousness were negatively related to levels of gambling involvement.
