With extant research on the relationship between trust and effectiveness being inconclusive, the present study attempts to create a foundational investigation that examines the role of multiple mediators in the team trust – team effectiveness relationship. The authors identified the two emergent states of cohesion and satisfaction as intervening variables in the team trust – team effectiveness relationship, and tested this multi-mediation proposed model, within an interdependence theory perspective.

MBA students at a large university in the southwestern USA were administered two waves of paper-based surveys, which were assigned to project groups. Individuals had been assigned to groups with the intent of maximizing diversity of age, gender, functional background, industry experience, and undergraduate major for each team (this is a goal of the MBA program, not the researchers). The first wave was administered one week after the groups had been formed and after all group members had met in their groups at least once. The second wave of surveys was administered at the end of the semester after the groups had been working together for three months and had completed their final projects.

The results of the multiple mediation analysis found support for the hypotheses that cohesion and satisfaction serve as dual mediators of the trust – team effectiveness relationship.

This study examined how trust operates through other variables to affect team performance. Two important variables that have been shown to be affected by trust are cohesion and satisfaction. Utilizing interdependence theory, the relationship of team trust and team performance was investigated through the intervening variables of cohesion and satisfaction, as both have been shown to possess properties that potentially represent different aspects of the interdependent relationship between team members. Therefore, this study examines how trust impacts team performance though the dual mediators of cohesion and satisfaction, in efforts to develop a more informed and theoretically grounded understanding of team performance and effectiveness processes.

Theories of trust imply that team trust develops and grows over time, yet relatively few researchers have taken on the challenge of studying team trust in longitudinal research designs. The purpose of this chapter is to provide a concise summary of the existing literature on team trust over time, and to offer a conceptual model of team-level trust development over time to aid future research on this topic.

We draw from the Input–Mediator–Output–Input (IMOI) framework, as well as previous multilevel models of organizational trust development, and published findings from longitudinal team trust studies.

Taking a temporal perspective, we consider how team-level mediators and outcomes can both predict and be predicted by team trust trajectories and feedback loops over time, as well as how those relationships with team trust might change based on the existence of other moderating variables including trust violation and repair.

Future longitudinal team research may use the model as a starting point for investigating the antecedents, as well as the team processes and dynamic emergent states, that can effectively predict trajectories of team trust across various stages of teamwork.

Based on our review of extant literature, we provide several recommendations for training and organizational intervention including the importance of management’s consideration of team-level trust in providing feedback, enhancing cohesion, and mitigating conflict.

We provide insight into the development of team trust trajectories and offer a framework to help guide future longitudinal team trust research.
