No. of bitstreams: 1 Dissertação Josmary vfinal.pdf: 958731 bytes, checksum: 99f22613883eb6a31dcd046c8ee98a08 (MD5) Previous issue date: 2016-08-29 / Estruturas sociais influenciam a efetividade dos grupos. O propósito deste estudo é explorar os efeitos contingenciais dessa relação por meio da investigação da densidade em diferentes redes na performance das equipes. Hipotetizou-se, primeiramente, o efeito oposto para densidade instrumental e afetiva em performance das equipes; posteriormente, argumenta-se que interdependência das tarefas e a orientação de distância de poder agem como moderadores. Para testar as hipóteses, foram utilizadas informações de questionários coletados de 27 Unidades de Pronto Atendimento (UPA) e 106 grupos. O resultado encontrado suporta o efeito positivo de densidade instrumental e o impacto negativo da densidade afetiva. Além disso, provou-se que a interdependência de tarefas atenua ambas as relações diretas. Ao final, são discutidas as implicações destes resultados para pesquisa em densidade das redes e performance das equipes. / Social structures influence team effectiveness. The purpose of this study is to explore the contingencies effects of this relationship by investigating density in distinct network contents on team performance. We first hypothesized opposite direct effects for instrumental and affective density on team performance; then we further argue that task interdependence and power distance orientation act as moderators. To test our hypotheses we use survey data from 27 Emergency and Care Units and 106 teams. The results support the positive effect of instrumental density and the negative impact of affective density. Moreover, task interdependence was found to attenuate both main relationships. We discuss the implications of these findings for research on network density and team performance.
