Leadership Theories

Go back to tutorial

Three main theoretical frameworks have dominated leadership research at different points in time. These included the trait approach (1930s and 1940s), the behavioural approach (1940s and 1950s), and the contingency or situational approach (1960s and 1970s).

Trait approach

The scientific study of leadership began with a focus on the traits of effective leaders. The basic premise behind trait theory was that effective leaders are born, not made, thus the name sometimes applied to early versions of this idea, the “great man” theory. Many leadership studies based on this theoretical framework were conducted in the 1930s, 1940s, and 1950s.

Leader trait research examined the physical, mental, and social characteristics of individuals. In general, these studies simply looked for significant associations between individual traits and measures of leadership effectiveness. Physical traits such as height, mental traits such as intelligence, and social traits such as personality attributes were all subjects of empirical research.

Leader Behaviour Approach

Partially as a result of the disenchantment with the trait approach to leadership that occurred by the beginning of the 1950s, the focus of leadership research shifted away from leader traits to leader behaviors. The premise of this stream of research was that the behaviors exhibited by leaders are more important than their physical, mental, or emotional traits. The two most famous behavioral leadership studies took place at Ohio State University and the University of Michigan in the late 1940s and 1950s. These studies sparked hundreds of other leadership studies and are still widely cited.

The assumption of the leader behavior approach was that there were certain behaviors that would be universally effective for leaders. Unfortunately, empirical research has not demonstrated consistent relationships between task-oriented or person-oriented leader behaviors and leader effectiveness. Like trait research, leader behavior research did not consider situational influences that might moderate the relationship between leader behaviors and leader effectiveness.

Contingency (Situational) Approach

Contingency or situational theories of leadership propose that the organizational or workgroup context affects the extent to which given leader traits and behaviors will be effective. Contingency theories gained prominence in the late 1960s and 1970s. Four of the more well-known contingency theories are Fiedler’s contingency theory, path-goal theory, the Vroom-Yetton-Jago decision-making model of leadership, and the situational leadership theory. Each of these approaches to leadership is briefly described in the paragraphs that follow.

Fiedler’s contingency theory has been criticized on both conceptual and methodological grounds. However, empirical research has supported many of the specific propositions of the theory, and it remains an important contribution to the understanding of leadership effectiveness.

 

Path-goal theory was first presented in a 1971 Administrative Science Quarterly article by Robert House. Path-goal theory proposes that subordinates’ characteristics and characteristics of the work environment determine which leader behaviors will be more effective. Key characteristics of subordinates identified by the theory are locus of control, work experience, ability, and the need for affiliation. Important environmental characteristics named by the theory are the nature of the task, the formal authority system, and the nature of the work group. The theory includes four different leader behaviors, which include directive leadership, supportive leadership, participative leadership, and achievement-oriented leadership.

The Vroom-Yetton-Jago decision-making model was introduced by Victor Vroom and Phillip Yetton in 1973 and revised by Vroom and Jago in 1988. The theory focuses primarily on the degree of subordinate participation that is appropriate in different situations. Thus, it emphasizes the decision-making style of the leader.

There are five types of leader decision-making styles, which are labeled AI, AII, CI, CII, and G. These styles range from strongly autocratic (AI), to strongly democratic (G). According to the theory, the appropriate style is determined by answers to up to eight diagnostic questions, which relate to such contingency factors as the importance of decision quality, the structure of the problem, whether subordinates have enough information to make a quality decision, and the importance of subordinate commitment to the decision.

Situational leadership theory has been criticized on both theoretical and methodological grounds.

However, it remains one of the better-known contingency theories of leadership and offers important insights into the interaction between subordinate ability and leadership style.
