The present study tried to make a Japanese self-handicapping scale and examined the scale to measure the individual differences in self-handicapping behavior. Subjects were 428 university students. In Study 1, the self-handicapping scale (Jones et al., 1986) was translated into Japanese. The self-handicapping scale was analyzed, its items and structure were checked for reliability, and so on. As a result "SH23" that consists of 23 items was made "SH23" was negatively correlated with self-esteem scales as predicted. In Study 2, the predictive validity was confirmed. Also two factors that are the "can't" factor and the "wouldn't" factor which were extracted in Study 1 were contributed independently to predict self-handicapping behaviors.
