Attachment style may influence the acculturation process by shaping the types of social relationships that individuals form and maintain. Social relationship quantity and quality have been linked to chronic low-grade systemic inflammation, an immune process associated with risk for age-related diseases. The goal of this study was to investigate whether attachment style moderates the change in systemic inflammation during the early phases of the acculturation process, a period associated with rapid changes in social functioning. In this 5-month longitudinal study, 58 new international students completed the Adult Attachment Scale and provided blood samples for C-reactive protein (CRP) analysis shortly after arrival in the host country as well as 2 and 5 months later. Results indicated that individuals with higher attachment anxiety experienced larger increases in CRP over time. During a period of rapid changes in social functioning, attachment anxiety promotes immune changes that may increase health risk over time.
