Abstract
Scientific substantiation of the factors, as well as procedural and effective characteristics of effective communication, allows overcoming the contradictions between the content and form that arise in modern communication, and thus helps to reduce the elevated level of conflict, which is the greatest burden of large and small social groups. That is why the purpose of the study was to identify the features of effective communication to improve the quality of communication as a basis for optimising social interaction and developing interpersonal relationships. The methods employed in this study included thematic analysis, conceptual analysis, synthesis, abstraction, and modelling. A theoretical analysis of the conceptual provisions on effective communication was performed. It was found that the effectiveness of communication is determined by the abilities, qualities, and communication skills of the subjects of communication, congruence, and empathy, which are manifested in their communication behaviour. It was found that effective communication helps to achieve mutual understanding of interlocutors, convergence of their psychological positions, determines the mutual development of communication subjects, serves as the basis for normalising the mental state of representatives of social groups, ensures positive group dynamics, and the development of constructive strategies for interpersonal interaction. The findings of scientific research on external factors of effective communication were summarised. It was found that a strong level of communication effectiveness is manifested in those situations of social interaction characterised by stability, predictability, and a prominent degree of certainty. Effective communication is one of the features of those social groups characterised by a strong level of cohesion, clarity of the role structure, and the presence of jointly developed values that define the organisational culture. The practical significance of this study lies in the possibility of considering the findings in the practice of professional communication of psychologists, social workers, teachers, managers, civil servants, and healthcare professionals; their application in determining the causes of destructive conflicts in interpersonal relationships and group interaction, identifying ways to prevent them
