Effects of the sex of a leader and of a respondent on evaluation of leader behavior were examined from the viewpoint of an implicit leadership theory and theories on sex-role stelectyping. 110 male and 698 female college students rated a Leader Behavior Descriprion Questionnaire (LBDQ) From XII, and Women as Managers Scale (WAMS). Results of the analysis indicated that the sex of both leader and respondent did not affect factor structure of leader behavior description, but did affect the level of leader behavior evaluation. Among male subjects WAMS was found to be contributed only by a limited, stereotyped LBDQ scales, while among female respondents a variety of LBDQ subscales showed significant contributions to WAMS. This indicated a dual-prejudiced view on female leadership.
