BACKGROUND: Social connection is critical to both psychological well-being and optimal immune function. The present study tested whether a behavioral intervention to increase social connection (promoting extraverted behavior) might reduce a threat-related immunoregulatory gene expression program known as the Conserved Transcriptional Response to Adversity (CTRA). The CTRA is characterized by elevated inflammatory gene expression and reduced innate antiviral gene expression in response to beta adrenergic signaling and has been associated with adverse social conditions such as loneliness and ostracism.
METHODS: In an 8-week intervention (with 6-week behavior change protocol), participants from a campus community (N = 119; 87 % undergraduate; 9 % graduate; 4 % staff) were randomized to act more extraverted (sociable; Extraversion condition) or track routine daily activities (Control condition). Participants reported on psychological outcomes and provided...
