Background: The study aims the analysis of leadership in National Health System. The present study focused at exploring the leadership models based on the answers of Multifactor Leadership Questionnaire by medical and nursing staff at St. Panteleimon, General Hospital of Nicaea Greece. Methods: The Multifactor Leadership Questionnaire (M.L.Q) by Avolio & Bass was given and convenience sampling method was used on May 2018. The population of the study was 386 male and female, medical 179 and nursing staff 205. Results: The Transformational leadership and intellectual stimulator, followed by idealized influenced- behavior and idealized influence-attributed are the most common answers. The laisser-faire management seems that is less dominant. The nursing staff seems that prefers the Transformational leadership rather than medical and the female population adopts Transformational leadership rather than men. The PhD and MSc owners prefer less passive management and laisser-faire management rather than the rest of the population study. Population with more years of experience prefers Transformational leadership with idealized influenced- behavior or idealized influence-attributed or inspirational motivator or intellectual stimulator rather than the youngest group age of population. Conclusion: Finally, the Transformational Leadership and intellectual stimulator, followed by idealized influenced- behavior and idealized influence-attributed are the most common answers.
