楽観バイアスが高齢者の特殊詐欺対策行動に及ぼす影響

抄録

Previous studies suggest that some elderly people do not use an answering machine at home to prevent falling victim to fraudulent scams despite this being known as one of the most effective behaviors to avoid fraud. The present study explored the influence of optimistic bias on answering machine use and behavioral intention for preventing fraud among elderly Japanese people. A survey was used among elderly Japanese respondents (N = 1,598, M_age = 73.2, SD = 5.30) to examine optimistic bias and behavioral intentions related to preventing scams targeting the elderly. Results of statistical analyses demonstrated that there was no relationship between optimistic bias and answering machine use. On the other hand, optimistic bias positively affected the behavioral intention of penetrating a scam by pretending to be deceived if respondents encountered scammers. We discuss the effects of optimistic bias and other factors, such as gender, on crime prevention behaviors regarding fraud.
