Proactive Personality Heterophily and the Moderating Role of Proactive Personality on Network Centrality and Psychological Outcomes: A Longitudinal Study

Purpose

In a social network study, this research investigates proactive personality dissimilarity as a basis for friendship ties over time. It also examines the moderating role of proactive personality on the relationship between network centrality and satisfaction/stress.

Design/Methodology/Approach

Longitudinal network data (two periods) were collected from business students (T1, n = 197; T2, n = 212). We captured the early stages of network formation and observed the changes in network structure over time.

Findings

Findings demonstrate proactive individuals develop ties with less proactive individuals over time, providing evidence of personality heterophily. In addition, proactive personality positively moderates the relationship between network centrality and satisfaction/stress. Interestingly, people’s perceptions of their network position (out-degree ties) were more strongly associated with their personal outcomes than their number of ties as nominated by others.

Originality/Value

This research is among the first to provide evidence of personality heterophily over time (relationships form because of differences in personality). Moreover, proactive personality is important to both the benefits and costs associated with network participation, pointing to paradoxical effects of proactive personality.
