This study was undertaken to discover working public thoughts about roles of United States women in leadership positions and to test the relationship between managerial leadership styles and organizational effectiveness. A survey of perceptions of leadership roles and effectiveness distributed 700 randomly selected entities from industries in the United States. Findings suggest approximately 50% of women leaders perceive barriers that prevent women for entering management positions and lower advancement rates for women. This study shows that aspiration in women exists whether or not they take action and motivate themselves to advance for top management positions. However, barriers like discrimination, family-life demands, prejudice, and stereotyping result in fruitlessness in many cases. The majority of women and men felt education and training could increase the preparedness of women for leadership roles. Respondents expressed overwhelming support for a participative leadership style. A positive association existed between participative leadership style and organizational effectiveness.
