Extant research demonstrates interrelationships among attachment style, love, and affectionate expression, but is less edifying regarding how these constructs work together. Informed by attachment theory (Bowlby, 1980) and the conceptualization of love as a motivational force (Rempel & Burris, 2005), the current study posits love as a mediator of the associations among attachment styles and affectionate communication. To examine this claim, 173 individuals in romantic relationships completed a questionnaire assessing the variables of interest. A path model revealed significant indirect effects (with the exception of the secure attachment style), and love mediated the relationships among preoccupied and dismissive attachment styles and affectionate expression. These findings suggest the important motivating capacity of love, an often overlooked predictor of relational processes.
