Abstract
To investigate the relationship between personality and multi-source feedback, we assessed 190 health care managers by applying the Understanding Personal Potential personality test, which provides comprehensive measurement of the Big Five dimensions and eight narrower personality traits. Managers' leadership behaviors were assessed by colleagues, supervisors, a random sample of each manager's subordinates as well as the managers themselves using a 360-degree change, production, employee (CPE) instrument. Hierarchical multivariate regression analysis showed that the Big Five variables were significantly related to the Managers' leadership behavior in all CPE dimensions. Also, addition of narrow personality variables to the Big Five increased explained variance in leadership behavior. This study is the first of its kind to include the full range of viewpoints in a 360-degree instrument, along with a large number of subordinate assessments. We found that both the strength of the relationship between personality and behavior and the configuration of different predictors varied depending on who did the rating and what leadership orientation was investigated, and this observation merits further investigation. © 2014 Scandinavian Psychological Associations and John WileyXX1Sons Ltd.
