“…MTL is a multidimensional construct that describes the net influence of three types of leadership motivation: (a) affective‐identity MTL , which reflects the extent to which team members view themselves as leaders and enjoy engaging in leadership behavior; (b) social–normative MTL , which reflects the extent to which team members perceive a sense of duty to engage in leadership behavior; and (c) noncalculative MTL , which reflects the extent to which team members tend to engage in leadership independent of the associated benefits or costs. Consistent with our theoretical interest in members’ total level of leadership motivation, as well as prior research that has examined the net impact of the three MTL dimensions, (e.g., Amah, ; Hadley, Pittinsky, Sommer, & Zhu, ; Krishnakumar & Hopkins, ; Luria & Berson, ), we focus our theorizing on team members’ overall MTL. Moreover, in keeping with studies that have explored team composition in terms of members’ individual attributes (e.g., LePine, ; LePine, Colquitt, & Erez, ), we conceptualize team member MTL as a team‐level variable consisting of the aggregate MTL of all team members.…”
