Any relationship, including marriage needs effective interpersonal communication to grow and endure.Due to a lack of awareness on effective interpersonal communication, married couples frequently undervalue the importance of interpersonal communication in their relationship as society adopts new communication channels. The purpose of this study is to understand better on how to conceptualise effective interpersonal communication using Relational Dialectic Theory and to examine how divorcees view communication in marriage. The causes of poor interpersonal communication and how it affects married couples were also examined in this study. By including communication technology as a medium of communication, the current study also expanded Knapp's Relational Development Model. A purposive sample strategy was used to select 20 divorcees from various states in Malaysia for in-depth interviews. The NVivo 12 programme was used to assess and compile the collected data into a thematic data analysis.This study found the antecedents of poor-quality interpersonal communication are communication skills, attitudes, third-party involvement and emotional condition. Overall, by incorporating the negative impacts of inadequate interpersonal communication into the model's degradation stages, the current study offers a new paradigm for Knapp's Relational Development Model.
