This study used latent change score models to examine how couples make progress toward resolution when they experience conflicts. It examined why negative conflict engagement might sometimes predict increased resolution, and how this process might be moderated by relationship satisfaction. A sample of 734 people in heterosexual marriages or cohabitation relationships were asked to identify an episode of relationship conflict and complete a questionnaire measuring types of negative behavior, attributions, anger, and soft emotion as well as measures of current discord, peak discord, positive behavior, and types of conflict disengagement. Negative engagement predicted peak levels of conflict discord, but for people in satisfying relationships, this effect was benign because large conflicts predicted large resolutions regardless of negative engagement levels.
