We distinguished the two content domains of TMMs: task and team. To
operationalize the task-TMMs we adapted three items of the scale developed to assess
the Marks et al. (2001) taxonomy of team processes (LePine et al., 2008). For
team-TMMs, we used three items of the Lim and Klein (2006) scale. Following Lim and
Klein (2006), we also included the sentence “My team is extremely effective” for each
dimension, in order to analyse the team members’ understanding of the relationship
between TMMs and effectiveness. We asked each team member to rate the relatedness
of the 12 pairs of statements on a seven-point scale (1 ¼ the sentences are not related
and 7 ¼ the sentences are extremely related). A list of pairs of sentences is provided in
