Abstract
The theoretical part of the thesis shortly introduces the topic of group communication and identifies relevant influencing factors. The subsequent summary of the research studying the impact of communication on work group performance illustrates not only the importance of the group communication topic itself, but also the development of diagnostic methods in this field.
Such methods are further summarised by focusing on their specific characteristics, differences and available validity and reliability data. The last chapter of the theoretical part briefly describes the sociomapping method measuring group communication with the up-to-date reliability and validity research.
The empiric part of the thesis combines several studies performed to verify the quality of the sociomapping method in the field of group communication.
