The influence of friendship and communication network density on individual innovative behaviours: a multilevel study.

The present study examines whether teams' friendship and communication network density are related to individual innovative behaviors (IIBs: idea generation, suggestion making, idea promotion and idea implementation). The study sample was composed of 28 teams comprising 101 members. The results obtained by means of multilevel structural equations modeling showed that friendship network density had an indirect positive relationship with the four IIBs, and that this relationship was mediated by the density of team communication networks.
