Romantic relationships are important as they influence physical health, general happiness, and overall well-being. However, they are not immune to disagreements. Conflicts can be a common occurrence in relationships, and poor conflict management can have negative consequences for relationship satisfaction, mental health, and relationship longevity. Attachment theory provides a lens through which to examine interpersonal functioning, and research has suggested that severe attachment disruptions such as interpersonal trauma may negatively influence relational functioning. Both interpersonal trauma exposure and insecure attachment style have been independently linked with impairments in interpersonal functioning, decreased romantic relationship satisfaction, and poor conflict management. However, there is little research that simultaneously examines how trauma and attachment are associated with relationship conflict management. The present study aimed to address this knowledge gap and expand upon current literature by simultaneously assessing these associations among a sample of college students in established romantic relationships (N = 365) using structural equation modeling. Measurement of a latent factor of insecure attachment was supported, and insecure attachment was significantly positively associated with interpersonal trauma. Interpersonal trauma did not predict conflict management strategies in the full model; however, insecure attachment was significantly negatively associated with compromise and positively associated with interactional reactivity, domination, submission, and separation in the modified model. These associations held while controlling for gender, relationship length, and religion. The results of this study contribute to our knowledge of relational difficulties and trauma among college students and have important implications for treatment for individuals with conflict management concerns.
