Emerging adulthood represents a liminal space between adolescence and adulthood. Attachment with a romantic partner is commonly developed during this time; however, the nature of the dating relationship often remains ambiguous and/or undefined. Dating provides emerging adults the opportunity to develop their romantic competence and navigate these particular attachment relationships. Conflict, and how it is managed, is a critical variable during this time and differentiates between couples who progress in their relationship from those who terminate. What is more, partners may become stuck in destructive cycles, or patterns, of conflict (i.e., demand-withdrawal). Using the theoretical frameworks of attachment theory and emotionally focused couples therapy, this study’s goal it to examine the impact of a brief writing-intervention on relational quality, secure attachment behaviors (i.e., accessibility, responsiveness, and engagement) and attachment dimensions (i.e., anxiety, avoidance). Sixty-seven participants were randomly assigned to one of three conditions for a two-wave study: (1) a treatment condition that was provided an educational presentation regarding couples’ negative cycles of interaction and attachment needs, followed by a guided writing task; (2) a comparison condition that only received the educational presentation; and (3) a control condition that received neither the educational presentation nor the writing task. Hypotheses proposed that participants in the treatment condition would experience increased relational quality, secure attachment behaviors (for both themselves and their partner), and greater secure attachment (i.e., decreased anxiety and avoidance) across time compared to the comparison and control conditions. Data did not support the hypotheses. These findings offer important implications for the development of future brief couples’ interventions and aim to generate future research.
