Relative leader-member relationships within group context Linking group cooperation to perceived group performance

Purpose - Although the importance of group leader and group member dyadic relationships has been increasingly emphasized, only few studies have focused on the dyadic level analysis of leader-member relationships. By integrating theories of relational leadership and relational dyadic communication among workgroups, the purpose of this paper is to propose a theoretical model that links relative leader-member exchange quality (RLMX) and relative leader-member conversation quality (RLMCQ) to group performance, as mediated by group cooperation. Design/methodology/approach - The model was tested in a field study with multiple sources, including 232 leader-member dyads and 407 workgroup peer dyads among 70 intact workgroups. Data were collected on-site during paid working hours from four training sessions. Group members were surveyed four times (Time 1, Time 2 and Time 3) and group leaders were surveyed once (Time 4) to minimize common method bias. The hierarchical linear modeling and polynomial regression approach were used to determine the mediating effects of the group cooperation. Findings - In this study, the authors found support for indirect effects of relative RLMX and RLMCQ on group performance through the mediating role of group cooperation. Research limitations/implications - The cross-sectional design of the current study is to be interpreted with caution, concerning any conclusions about the causal ordering of the variables in the model. Practical implications - In organizational situations with group leaders and group members already in high-quality relationships and conversation, management should endeavor to facilitate opportunities for cooperation among group members and a means to also enhance team-member exchange. Originality/value - By introducing LMCQ and group member cooperative behavior in workgroups, this study actively respond to the scholars' warnings that ignoring the workgroup context may hamper the progress in understanding the factors that will inhibit or enhance workgroup behavior.
