This research aims to adapt and examine the validity and accuracy of the 6-item Machiavellian Managerial Practice Scale in Turkish, which is a sub-dimension of the Organizational Machiavellianism Scale developed by Kessler et al., (2010). In this context, construct validity (only in terms of convergent validity), factor structure (confirmatory factor analysis) and reliability (internal consistency) of the Machiavellian Managerial Practices Scale were tested. In order to test construct validity, narcissism, Machiavellism, psychopathy, and counterproductive work behavior scale were used. According to the results of the research, Machiavellian Managerial Practice Scale was positively identified with narcissism, Machiavellianism, psychopathy, and counterproductive work behavior. These findings supported the convergent accuracy of the Machiavellian Managerial Practice Scale. Dependent factor analysis showed that the fit index supported the factor structure of the scale. Finally, the internal consistency of the scale was calculated at an acceptable level. As a result, the psychometric properties of the Turkish version of the Machiavellian Managerial Practice Scale were found to be at an acceptable level.
