The purpose of the present study was to identify the dimensional features of achievement motivation and to investigate the nature of the relationship between achievement motivation and personality. Doi's motivation scales and Yatabe-Guilford personality inventory were administered to 217 male university students. Factor analyses and canonical correlation analysis were used to extract two dimensions of achievement motivation- (1) affiliative achievement motivation and (2) non-affiliative achievement motivation. Affiliative achievement motivation was positively correlated with achievement, affiliation and general activity and negatively correlated with lack of cooperativeness. Non-affiliative achievement motivation was positively correlated with achievement, depression, nervousness and lack of cooperativeness and negatively correlated with affiliation and thinking extraversion. These findings suggested that the relationship between achievement motivation and personality may depend on cultural factors.
