The purpose of this research was to examine the joint impact of leader achievement goals and hierarchical position of the voicer of creative ideas (subordinate vs. superior) on the extent to which leaders (intent to) integrate these voiced creative ideas with their own ideas (integrative idea management). In a scenario‐based survey (study 1; N = 189), in which we measured participants' achievement goals, we found that the relationship between leaders' performance goals and their intention to integrate voiced creative ideas is contingent on the hierarchical position of the idea voicer. Similarly, in an experimental study (study 2; N = 94), in which we experimentally induced achievement goals, we found that leaders display lower integrative intentions when ideas are voiced by a subordinate rather than a superior, but this was only true for leaders pursuing performance goals. Furthermore, the results of an additional, exploratory analysis suggest that the hierarchical position of the voicer of creative ideas had an indirect effect on integrative behavior through integrative intentions for performance goal leaders and no effect for mastery goal leaders. Together, these findings advance our understanding of how middle management leaders are influenced by their own achievement goals when managing the creative ideas voiced by subordinates and superiors.
