The authors analyze the psychometric properties of the Inventory for Supervisor Assessment (INESUP). Based on the tridimensional leadership theory proposed by Yukl (2003), three basic categories of effective behaviors emerge: Task-oriented, Relations-oriented, and transformational. The application of the questionnaire includes two sources of information: Self-reports and upward reports (from subordinates). Comparing the self- and upward-ratings makes feedback possible, which may foster desirable behaviors and attitudes. The inventory was used on a sample composed by 10 supervisors and 89 subordinates in a financial firm. Analyses validated the instrument’s 9-factor structure and the type of scale used, as well as its reliability.
