I am not sure if permission is needed but I am having trouble finding the holder of the copyright for the Survey of Perceived Organizational Support (SPOS) developed by Eisenberger et al. (1986), Thanks for the help!
If you're doing research, generally no copyright permission is necessary to use a scale. However, you must cite it correctly. It would also be nice to cite other key articles that were written by the authors that are relevant to the scale.
