Team leadership: Network differences in women's and men's instrumental andexpressive relations

Recent studies have emphasised differences in leadership styles between wom en and men. Women have an "interactive" leadership style while men are more "directive" and "authoritative." Social network analysis is used to examin e differences in eight mental health case management teams, half formally s upervised by women and half by men. The techniques used are graphical displ ays and measures of centrality. Results show male leaders as the most centr al team member for both instrumental and expressive relations. Female leade rs, however, do not adhere to a single leadership style. Team centralisatio n also differs with gender composition of teams influencing leadership diff erences.
