Depression and everyday social interaction.

The present study examined the relationships between depressive symptoms and everyday social interaction in a nonclinical population. Depressive symptoms were measured using the Center for Epidemiological Studies Depression Scale, and social interaction was measured using a variant of the Rochester Interaction Record. People who were classified as at risk for depression had less rewarding interactions than people who were not at risk. Depressive symptoms and interaction quantity and quality were negatively correlated for participants above the cutpoint, whereas they were uncorrelated for those below the at-risk cutpoint. The results also suggested that, compared with nondepressed people, depressed people derive more rewards from interactions with their closest opposite-sex friends, relative to the rewards they derive from interactions with other opposite-sex friends.
