This questionnaire for measuring charismatic leadership was developed by the research group around Conger and Kanungo and measures a total of five facets of charismatic leadership (Sensitivity to the environment, Sensitivity to members' needs, Strategic vision and articulation, Personal risk, and Unconventional behavior).
The questionnaire was translated into German and used in several samples (including business leaders, non-profit leaders, and politicians). The CKS questionnaire has been extensively scientifically validated.
Overall, the CKS has good psychometric properties (cf. Rowold, J., Kersting, M. (2008). The assessment of charismatic leadership: Validity of a German version of the Conger-Kanungo Scales. European Journal of Psychological Assessment, 24 (2), 124-130.
