Psychological well-being

Intimate relationships impact happiness and satisfaction with life. While people with better mental health are more likely to enter intimate relationships, the relationships themselves also have a positive impact on mental health even after controlling for the selection effect. In general, marriage and other types of committed intimate relationships are consistently linked to increases in happiness. Furthermore, due to the interdependent nature of relationships, one partner's life satisfaction influences and predicts change in the other person's life satisfaction even after controlling for relationship quality.
