Реферат: The Value Based Leadership Theory
There is extensive empirical evidence with respect to the effects of behaviors specified by value based leadership theory. Charismatic, visionary, and transformational theories of leadership are precursors of the leader behaviors specified by value based leadership theory. Tests of these theories have been based on various operationalizations that qualify as measures of value based leadership including interviews (Howell & Higgins, 1990), laboratory experimentation (Howell & Frost, 1989; Kirkpatrick & Locke, 1996), questionnaires (Lowe, Kroeck & Sivasubramaniam, 1995), and quantified archival data (House, Spangler & Woycke, 1991). In all of these tests, the leader behavior measured consists of articulating an organizational vision and behaving in ways that reinforce the values inherent in the vision, thus qualifying as indirect evidence relevant to the effects of value based leadership. Space limitations prevent a detailed review of the evidence. However, Bass and Avolio (1993), House and Shamir (1993), Lowe et al,. (1995), and Yukl (1994), present overviews of these studies. With surprising consistency these empirical studies have demonstrated consistently that value based leader behavior predicts unusual levels of leader effectiveness directed toward enhancing organizational performance.
Support for the effects of value based leadership is illustrated by a recent meta-analysis of the charisma subscale of the Bass and Avolio (1989) Multifacet Leadership Questionnaire (MLQ) . The MLQ charisma subscale describes relationships between subordinates and superiors. Superiors who receive high scores on this scale are described by subordinates as having an exciting vision of the future for the organization they lead, and being exceptionally motivational, trustworthy, and deserving of respect.
Support for the theoretical main effects of value based leader behavior has been demonstrated at several levels of analysis including dyads, small informal groups, major departments of complex organizations, overall performance of educational and profit making organizations, and nation states. The evidence is derived from a wide variety of samples including military officers, educational administrators, middle managers, subjects in laboratory experiments and management simulations, US presidents and chief executive officers of Fortune 500 firms (Bass & Avolio, 1993; House & Shamir, 1993; Waldman, Ramirez & House, 1996).
The evidence shows that the effects of value based leader behavior are rather widely generalizable in the United States and that they may well generalize across cultures. For instance, studies based on the charisma scale of the MLQ have demonstrated similar findings in India (Periera, 1987), Singapore (Koh, Terborg & Steers, 1991), The Netherlands (Koene, Pennings & Schreuder, 1991), China, Germany, and Japan (Bass, 1997).
In summary, the studies based on various operationalizations of value based leadership clearly show that this genre of leadership results in a high level of follower motivation and commitment and well-above-average organizational performance, especially under conditions of crises or uncertainty (Pillai & Meindl, 1991; House, Spangler, & Woycke, 1995; Waldman, Ramirez & House, 1996; Waldman, Atwater & House, 1996).
NEWLY INTEGRATED THEORIES
The value based theory of leadership integrates the precursor theories discussed above with a number of assertions advanced in several psychological theories of motivation and behavior. Following is a brief review of the psychological theories that are integrated into the Value Based Leadership Theory.
McClelland's Theories of Non-conscious Motivation
According to this theory, the motivational aspects of human beings can be understood in terms of four non-conscious motives in various combinations (McClelland, 1985). These motives are the achievement, power, affiliation, and social responsibility motives. McClelland has developed a theory of entrepreneural effectiveness based on the role of achievement motivation, and a more general theory of leader effectiveness consisting of theoretical assertions concerning the optimum combination of the above four motives for effective leadership. This theory is entitled the Leader Motive Profile Theory (LMP). In the following sections we discuss the four motives discussed by McClelland and the LMP theory.
Achievement Motivation
Achievement motivation is defined as a non-conscious concern for achieving excellence in accomplishments through one's individual efforts (McClelland, Atkinson, Clark, & Lowell, 1958). Achievement motivated individuals set challenging goals for themselves, assume personal responsibility for goal accomplishment, are highly persistent in the pursuit of goals, take calculated risks to achieve goals and actively collect and use information for feedback purposes. Achievement motivation is theoretically predicted to contribute to effective entrepreneurship (McClelland, 1985) and effective leadership of small task oriented groups (House et al., 1991). Litwin and Stringer (1968) demonstrated experimentally that small groups led by managers who enacted achievement oriented and arousing behaviors were more effective than groups with managers who did not.
In management positions at higher levels in organizations, and particularly in organizational settings where technical requirements are few and impact on others is of fundamental importance, managerial effectiveness depends on the extent to which managers delegate effectively and motivate and co-ordinate others. Theoretically, high achievement motivated managers are strongly inclined to be personally involved in performing the work of their organization and are reluctant to delegate authority and responsibility. Therefore, high achievement motivation is expected to predict poor performance of high-level executives in large organizations. House et al. (1991) found that achievement motivation of U.S. presidents was significantly inversely related to archival measures of U.S. presidential effectiveness.
Affiliative Motivation
Affiliative motivation is defined as a non-conscious concern for establishing, maintaining, and restoring close personal relationships with others. Individuals with high affiliative motivation tend to be non-assertive, submissive, and dependent on others (McClelland, 1985). Theoretically, highly affiliative motivated managers are reluctant to monitor the behavior of subordinates, to convey negative feedback to subordinates even when required, or to discipline subordinates for ethical transgressions or violations of organizational policies. Highly affiliative motivated managers are also theoretically expected to manage on the basis of personal relationships with subordinates and therefore show favoritism toward some. House et al. (1991) found that the affiliative motive was significantly negatively correlated with U.S. presidential charismatic leadership and archival measures of U.S. presidential effectiveness.
Power Motivation
Power motivation is defined as a non-conscious concern for acquiring status and having an impact on others. Individuals with high power motivation tend to enjoy asserting social influence, being persuasive, drawing attention to themselves, and having an impact on their immediate environment including the people with whom they interact. Theoretically, if enacted in a socially constructive manner, high power motivation should result in effective managerial performance in high level positions (McClelland, 1975; 1985). However, unless constrained by a responsibility disposition, power motivated managers will exercise power in an impetuously aggressive manner for self aggrandizing purposes to the detriment of their subordinates and organizations.
High power motivation induces highly competitive behavior. Therefore, when unconstrained by moral inhibition, power motivation is theoretically predictive of leader effectiveness when the role demands of leaders require strong individual competitiveness, aggressiveness, manipulative exploitive behavior, or the exercise of substantial political influence. The power motive was found by House et al. (1991) to significantly predict presidential charismatic behavior and archival measures of presidential effectiveness.
Responsibility Disposition
According to McClelland, individuals who have a high concern for the moral exercise of power will use power in an altruistic and collectively-oriented manner. Indicators of high concern for responsibility are expressions of concern about meeting moral standards and obligations to others, concern for others, concern about consequences of one’s own action, and critical self judgment.
Winter and Barenbaum (1985) developed and validated a measure of concern for moral responsibility, which they label the responsibility disposition1. The measure is based on quantitative content analysis of narrative text material. Winter (1991) demonstrated that the responsibility disposition, in combination with high power and low affiliative motivation, was predictive of managerial success over a sixteen-year interval.
The responsibility motive should be predictive of leader integrity and leaders' concern for the consequences of their own actions on others. Leaders with high responsibility disposition are expected to stress the importance of keeping one's word, honesty, fairness, and socially responsible behavior. Thus, we expect the responsibility disposition to be associated with value based leader behavior, supportive leader behavior, fairness, follower trust and respect for the leader and commitment to the leader’s vision, and consequently organizational effectiveness.
Leader Motive Profile Theory
McClelland (1975) argued that the following combination of non-conscious motives are generic to, and predictive of, leader effectiveness: high power motivation, moderate achievement motivation, high concern for the moral exercise of power, and power motivation greater than affiliative motivation. This combination of motives is referred to by McClelland (1975) as the Leader Motive Profile (LMP).
According to LMP theory, the power motive is necessary for leaders to be effective because it induces them to engage in social influence behavior, and such behavior is required for effective leadership. Further, when the power motive is higher than the affiliative motive, individuals do not engage in the dysfunctional behaviors usually associated with high affiliation motivation - favoritism, submissiveness, and reluctance to monitor and discipline subordinates. Finally, when high power motivation is coupled with a high concern for moral responsibility, individuals are predicted to engage in the exercise of power in an effective and socially desirable manner. Earlier research, also reviewed by McClelland (1985), suggests that the achievement motive is a better predictor of leader effectiveness and success in entrepreneurial organizations than LMP.
Theoretically the leader motive profile is predictive of managerial effectiveness under conditions where leaders need to exercise social influence in the process of making decisions and motivating others to accept and implement decisions. In formal organizations these conditions are found at higher levels and in non-technical functions. By contrast, in smaller technologically based organizations, group leaders can rely on direct contact with subordinates (rather than delegation through multiple organizational levels), and technological knowledge to make decisions. Thus LMP theory is limited to the boundary conditions of moderate to large non-technologically oriented organizations (McClelland, 1975; Winter, 1978; 1991), and to managers who are separated from the work of the organization by at least one organizational level.
Several studies have demonstrated support for the LMP theory. Winter (1978) found that LMP was predictive of the career success of entry level managers in non-technical positions in the US Navy over an eight-year interval. Both McClelland and Boyatzis (1982), and Winter (1991), in separate analyses of the same data but with different operationalizations of LMP, found similar results at AT&T over a sixteen-year interval. McClelland and Burnham (1976) found high-LMP managers had more supportive and rewarding organizational climates, and higher performing sales groups than low-LMP managers did in a large sales organization. House, et al.(1991) found that the motive components of the LMP predicted US presidential charisma and presidential performance effectiveness.
Since high LMP leaders have greater power than affiliative motivation it is expected that they will be assertive and at least moderately directive. Further, since they have high responsibility motivation it is expected that thay will have highly internalized idological values - values concerning what is morally right and wrong - and that they will thus stress ideological value orientation, integrity, and fairness, as explained above, both verbally and through personal example.
The Path-Goal Theory of Leadership
The essence of path-goal theory is that leader behaviors will be effective when such behaviors complement formal organizational practices and the informal social system by providing direction, clarification, support and motivational incentives to subordinates, which are not otherwise provided (House, 1971; House & Mitchell, 1974; House, 1996). According to the 1996 version of path-goal theory, leaders who give approval and recognition of subordinates, contingent on performance and in a fair manner, will clarify expectancies of subordinates concerning work goals and rewards, and will effectively motivate subordinates. This theory also predicts that leader consideration toward subordinates provides the psychological support subordinates require, especially in times of stress and frustration.
