This study examined how transformational leadership (TFL) influences adaptive selling behavior by both psychological capital (at the individual-level) and team cohesion (at the team-level). This multilevel study includes 334 individual members from 36 teams. Hierarchical Linear Modeling revealed that teamlevel TFL was positively related to follower adaptive selling behavior, with this relationship mediated by follower psychology capital. Furthermore, team-level TFL was positively associated with team cohesion, and team cohesion further enhanced follower adaptive selling behavior. We discuss implications of these findings, limitations, and directions for future research.
