I am searching the questionnaire for the diversity within groups, innovation, and knowledge sharing. If anyone could share me, it will be a big help for my PhD paper for degree requirement.
The work from Van den Hooff and De Ridder (2004) provides a very strong scale on knowledge sharing:
Van den Hooff, B., & De Ridder, J. A. (2004). Knowledge sharing in context: the influence of organizational commitment, communication climate and CMC use on knowledge sharing. Journal of knowledge management, 8(6), 117-130.
The work of Oliveira et al. (2015) provides two different scales for knowledge sharing behaviour and a scale for innovation:
Oliveira, M., Curado, C. M., Maçada, A. C., & Nodari, F. (2015). Using alternative scales to measure knowledge sharing behavior: Are there any differences?. Computers in Human Behavior, 44, 132-140.
