The construct of locus of control carefully examines personality studies to gain insight into self-evaluation and its link to leadership qualities. The nature and importance of the “locus of control” construct The locus of control construct can be interpreted in various ways to reveal how personal ideologies can influence choice and reason. The locus of control in its nature can be deciphered in various ways according to theoretical approaches. Julian Rotter's (1966) internal-external scale introduced a unidimensional approach to understanding individuals' perceptions of situational outcomes in the real world (Levenson 1981, Pg 16-18). This construct originally proved effective for the managerial sector of businesses to enable smooth exchanges between leaders and members. Conversely, it has also been widely criticized due to the strength of variable relationships in the external scale. Individuals often reside in an internal mindset where they believe they can produce a result with hard work and perseverance. Alternatively, other individuals possess an external mindset, with a causal effect related to goal achievement relating more directly to external forces that are powerful, to others, and to chance. As a result of the external scale linking powerful others and chance so cohesively, Rotter's construct has received criticism for being one-dimensional (Levenson 1981). Hersch and Schiebe (1967) (cited in Levenson p. 16) "suggest that a theoretical and empirical differentiation of externality would be useful in understanding the relationship between personality and adaptation." As a result of this, it can be concluded that the multidimensional approach of the Levenson IPC scale has a higher conception… halfway through the article… a theory but is based on “five sources; intrinsic process, instrumental process, external self-concept, internal self-concept and internalization of goals”. (Barbuto et al, 2010). Internal self-concept motivation is central to leadership as it provides a broad basis for self-evaluation whereby an individual's ability to complete the tasks at hand produces confidence and satisfaction, reflecting a locus of control internal. This form of motivation provides leaders' ability to appreciate each characteristic that is beneficial to employees for the company and enables consistent results in the workplace. Furthermore, internalizing goal motivation allows employees to gain insight into the meaning of tasks in order to find the desire to succeed internally and in collaboration with colleagues, subsequently the ability to express internalizing goals is crucial for leadership.
