Differential Behavioral Pathways Linking Personality to Leadership Emergence and Effectiveness in Groups.

This study integrates leadership process models with process models of personality and behavioral personality science to examine the behavioral-perceptual pathways that explain interpersonal personality traits' divergent relation to group leadership evaluations. We applied data from an online group interaction study (N = 364) alternately assigning participants as leaders conducting brief tasks. We used four variable types to build the pathways in multiple mediator models: (a) Self-reported personality traits, (b) video recordings of expressed interpersonal behaviors coded by 6 trained raters, (c) interpersonal impressions, and (d) mutual evaluations of leadership emergence/effectiveness. We find interpersonal big five traits to differently relate to the two leadership outcomes via the behavioral-perceptual pathways: Extraversion was more important to leadership emergence due to impressions of assertiveness evoked by task-focused behavior being strongly valued. Agreeableness/emotional stability were more important to leadership effectiveness due to impressions of trustworthiness/calmness evoked by member-focused/calm behavior being stronger valued.
