The possibility that women in positions of leadership need to engage in sex-role appropriate behaviors in order to be effective has been investigated recently. In order to explore whether a sex appropriate, Considerate style helps women to be more influential and effective leaders than a sex inappropriate, Dominant style, 47 mixed-sex groups (N=188) participated in a role-play designed to simulate an organizational decision-making situation. The subjects were graduate students in business administration, members of an introductory Organization Behavior class. The results showed that women with male subordinates were more influential when they employed a Considerate style. No differences were found when subordinates included women as well as men. While the women in this study were highly influential leaders, their groups were not particularly successful in reaching the more creative solutions. This latter result suggests that conflict managment may be a particularly sensitive issue for women in management positions. (Results of analyses of leader influence, leader collaboration, and ratings of leader effectiveness by subordinates and leaders are appended in tables.) (Author/LLL)
