This investigation extends the work of Stamp, Vangelisti, and Daly (1992) and others by explicating the multifaceted process of defensive communication among romantic couples. Qualitative data were derived from self-reports about a distinct episode of defensive communication in individual interviews, as well as direct analysis of couples' communication in joint interviews. The proposed theoretical model reflects a more comprehensive, holistic, and precise framework that accounts for the triggers, core episode, outcomes, and contexts of defensive communication. The detailed model, which draws attention to interactive and person-centered features of defensive communication, is illustrated through the narrative account of one couple. Eleven data-based postulates are offered to fuel and focus subsequent investigations.
