Successful conflict resolution is important in romantic relationships. With the advent of computer-mediated communication (CMC), partners can resolve conflict using CMC. But is CMC as effective as face-to-face communication for conflict resolution? And does the effectiveness depend on attachment style? We asked 100 romantic couples to discuss a conflict topic and randomly assigned them to do so face-to-face or via CMC. Levels of distress, anger, and conflict resolution did not differ between face-to-face and CMC discussions. Attachment style did not moderate these findings. A more anxious and a more avoidant attachment style were associated with higher levels of distress and anger. We conclude that there is no indication that resolving conflict face-to-face has advantages over resolving conflict via CMC.
