Abstract
This study integrated social network analysis (SNA) techniques with psychological measures to examine the interactive relationships of social network centrality and individual motive on the performance of interpersonal citizenship behavior (ICB). Hypotheses were tested among a sample of 141 employees of a manufacturing and sales firm. Consistent with a social exchange perspective, positive pro-social and organizational concern motives were not moderated by an employee's centrality in organizational networks. Conversely, a hypothesized interaction was supported between impression management motives and network centrality on performance of ICB. Results suggest that both motive types operate on the performance of ICB, but under different conditions. Implications for the study of impression management and social exchange motives, the study of ICB, the integration of SNA into the study of ICB, and practitioner implications are discussed.
