NOTES
1. The final six-item scale included five of the newly developed items, and one item,
Item 1, was inspired by the second item of the Communicator Competence Questionnaire
by Monge et al. (1982). See Appendix.
2. In all four studies, established ethical standards were met. Each participant was
informed about the purpose of the study and about the way the data is protected (data
protection fact sheet), responded voluntarily, and anonymously sent back the questionnaire
in a business reply envelope.
