Dear Chaitanya,
Thanks for posting. I will take this opportunity to inform readers that when using material found elsewhere, even if we modify the design, we should attribute the source, even for ideas, to avoid plagiarism.
For example, please see
Leadership Motivation Test - Take our online test now! where Mindtools have given a note about the validity and reliability of a similar questionnaire and added the following:
".......This self-assessment was patterned after that of A. J. DuBrin in Leadership: Research Findings, Practice and Skills (2nd edition) (Boston: Houghton Mifflin Co., 1998). Pp. 10-11."
