This document provides an overview of leadership theories including trait approach, behavioral approach, and situational approach. It discusses key theories such as:
- Trait approach which proposes that successful leaders possess certain innate qualities and traits.
- Behavioral approach including Ohio State and Michigan studies, which focused on how a leader's behaviors can influence outcomes. Specifically, consideration vs initiating structure and employee-centered vs production-centered styles.
- Situational approach which suggests the most effective leadership style depends on the situation and factors like the task and the followers.
The document also summarizes criticisms of early theories and additional leadership styles identified in subsequent research.
