The authors compared a feedback workshop with both a no-feedback control group and a comparison group of managers who received a feedback report but no feedback workshop. The multisource feedback was based on ratings of a manager's influence behavior by subordinates, peers, and bosses. Managers in the feedback workshop increased their use of some core influence tactics with subordinates, whereas there was no change in behavior for the control group or for the comparison group. The feedback was perceived to be more useful by managers who received it in a workshop with a facilitator than by managers who received only a printed feedback report.
