Trust in Leader as Antecedent to Trust in Team Members, Team Cooperation, and Team Performance: A Multilevel, Longitudinal, Mediational Perspective.

Abstract

Trust in leaders plays a central role in shaping how teams function and perform. While prior research has explored leadership styles and outcomes, the mechanism by which trust in leaders influences team dynamics remains underexplored; particularly from a multilevel, longitudinal perspective. The current study investigated the role of trust in team members as a mediator in the relationship between trust in the leader and team cooperation, and team cooperation as a mediator in the relationship between trust in team members and team performance. Drawing on social contagion theory, this study develops and tests a cascading trust model in which trust in the leader fosters trust among team members, enhances team cooperation, and ultimately improves team performance. Data were collected in two waves over three months from 307 employees across 71 teams in Malaysian private-sector organizations. Using multilevel modelling, the results showed that trust in the leader had a positive relationship with trust in team members, team cooperation, and team performance. Trust in team members also mediated the relationship between trust in the leader and team cooperation, while team cooperation mediated the relationship between trust in team members and team performance. This study extends existing trust and leadership literature by uncovering the affective processes through which trust flows within teams and by highlighting the leader's role in cultivating a high-trust, high-performing team environment, particularly salient in collectivist, relationship-focused contexts. Practical implications for cultivating high-trust, high-performing teams are discussed.
