Climbing the Higher Mountain: The Challenges of Multilevel, Multisource, and Longitudinal Research Designs.

abstract Management researchers are being encouraged to collect multilevel, multisource, and longitudinal (MML) data. In this essay, I identify the barriers that researchers might encounter in gaining university ethics committee approval for MML designs and the challenges researchers face when conducting MML research in organizations. I offer suggestions to overcome these challenges. I further discuss some long-term consequences of MML designs for researchers' relationships with organizations and the progress of the management field as a whole. [ABSTRACT FROM AUTHOR]
