Attachment anxiety in daily experiences of romantic relationships: An expansion of the mutual cyclical growth model

Abstract

This research provides a conceptual replication and theoretical extension of the mutual cyclical growth model. This model proposes that dependence promotes relationship commitment, which promotes pro-relationship behavior, which—when detected by partners—promotes partners’ trust, which promotes partners’ willingness to depend on the relationship. Prior research supports these links on a month-to-month basis, but romantic partners’ thoughts, feelings, and behaviors may change on a day-to-day basis. The present research sought to replicate the model on a daily level, and to extend the model with an important potential moderator: individuals’ attachment orientations. Results from a dyadic daily-report study of romantic couples replicated the links in the mutual cyclical growth model at the level of day-to-day fluctuations in partners’ experiences; the links were especially strong for individuals high in attachment anxiety. This research provides insight into mechanisms through which close relationships develop and strengthen.
