The aim of this study is to identify the principles of Choice Theory in interpersonal communication in the partnership and also to describe what contributes to satisfaction during interpersonal communication in the current relationship and what communication patterns impair quality relationship. The first part of the paper provides an overview of some of the research in the field of interpersonal communication and lays out basic principles of the Choice Theory. This will be followed by a discussion about acquired data, potential obstacles in the research with description of how they were overcame and possible utilization of research results. The research confirmed the main hypothesis which argues that the use of Choice Theory axioms contributes to the feeling of pleasure with the current relationship. Furthermore, the research results presented in this paper may be useful for Reality Therapy, a psychotherapeutic school based on Choice theory, since results confirm that Choice Theory is applicabile and effective in the process of self-development and increasing satisfaction within the relationship / interpersonal communication. The answers present a more concrete insight into potential effectivnes of applying Choice Theory axioms to interpersonal processes, while confirming the main hypotesis also confirmed the effectivness of applying the Choice Theory axioms to interpersonal communication. This paper also seeks to broaden our knowledge on such communication in close relationships which is extraordinary complex and therefore challenging to study.
