Are people with social anxiety disorder happier alone?

Quality contact with other people serves as a reliable mood enhancement strategy. We wondered if the emotional benefits of socializing are present even for those with a psychological disorder defined by social distress and avoidance: social anxiety disorder (SAD). We conducted two ecological momentary assessment (EMA) studies and analyzed 7243 total surveys. In both studies, community adults diagnosed with SAD and healthy controls received five surveys each day for 2 weeks. Consistent with research on positivity deficits in SAD, between-person analyses in both studies suggest that, on average, participants with SAD reported lower positive and higher negative affect in social and non-social situations than healthy controls. Within-person analyses, however, revealed that in both studies participants with SAD and healthy controls reported higher positive affect when with others than when alone; no differences were found for negative affect for those with SAD. The difference in positive affect between social and nonsocial situations was smaller for participants with SAD in Study 1, suggesting that people with SAD may experience diminished reward responding when socializing. Our results suggest that even those with a mental illness defined by interpersonal distress can and do derive positive emotions from social interactions.
