이질성 연구에 대한 새로운 접근 : 이질성의 새로운 지표 조직시민행동(OCB)

As is generally known, dissimilarity among group members has negative effects on social integration of the group. But up to now most researchers, with few exceptions, are dealing with this issue by focusing on the role of demographic dissimilarity, and revealing some limitations. Recently some researchers are criticizing this research tendency, and suggesting that we could use deep-level characteristics(for instance attitudes, beliefs, and values), instead of demographic variables, as another indicator of dissimilarity. This study stands on the extension of this criticism, but goes one step further. Because this study insists that we resort to OCB as a new indicator of deep-level dissimilarity. Calling this OCB dissimilarity, this study is analysing the negative effects of OCB dissimilarity on social integration(group attractiveness & efficacy). The important findings are as follows. First, OCB dissimilarity shows negative relationship with the outcome variables. Second, this relationship is mediated by coworker trust. That is, as the level of OCB dissimilarity increases, the level of coworker trust decreases, and so do the levels of group attractiveness & efficacy. Third, OCB dimensions differentiate this relationship. Specifically, wheres OCBO(OCB toward organization) shows no significant effects on outcome variables, OCBI(OCB toward individuals) shows very significant effects on outcome variables. In conclusion, as is hypothesized in this study, OCB dissimilarity has negative effects on social integration. This results supports the proposition that OCB could be used as a new indicator of dissimilarity. This paper ends with theoretical implications and suggestions for future research directions.
