The Multiple Identities Study is based on 25 years of data collected from 3714 students at an ethnically diverse small college in Southern California. Both women and men who were romantic partners rated themselves more physically attractive, self-confident, and satisfied with themselves as a person than singles. They also reported higher self-esteem and more happiness. They reported somewhat greater secure attachment and less fearful attachment than singles. Women who were romantic partners also reported less depression, while men who were romantic partners reported greater life satisfaction. But romantic partners did not differ from singles in anxiety. And having a successful career and spending time with friends did not differ as goals in life between romantic partners and singles, among both women and men.
