The purpose of this research was to identify how enduring personality characteristics predict a person's location in a network, locations which in turn affect outcomes such as performance. Specifically, this thesis examines how self-monitoring and locus of control influence an individual's location in a friendship social network over time. Hierarchical Linear Modeling (HLM) was used to analyze 28 groups of students and instructors at a military training course over six and one half weeks. Self-monitoring predicted betweenness centrality in five of six time periods while locus of control predicted betweenness centrality in three of six time periods. The moderation of self-monitoring on locus of control also determines social network centrality. A longitudinal analysis suggested that self-monitoring was not related to the rate of increase of centrality over time. Organizational leaders may benefit in better identifying influential social network employees by their personality make-up and assigning them where their impact will be most valuable.
