Romantic relationships in the ecosystem: Compassionate goals, nonzero-sum beliefs, and change in relationship quality.

According to the egosystem-ecosystem theory of social motivation, people with ecosystem motivation believe their interpersonal relationships work in nonzero-sum ways. A longitudinal study of individuals in romantic relationships and a study of romantic couples who had a conflict discussion in the laboratory both showed that compassionate goals predict increased nonzero-sum beliefs through increased responsiveness and perceptions of partner's responsiveness and that nonzero-sum beliefs uniquely predict increased relationship quality through increased optimism that relationship problems can be overcome. The results support the view that motivational orientations shape people's lay theories that their relationship works in zero-sum or nonzero-sum ways, and further show that nonzero-sum beliefs are an important and unique predictor of change in relationship quality independent of responsiveness or perceived partner responsiveness.
