This review focuses on studies that have examined the relation between psychosocial factors and secretory immunoglobulin A (s-IgA). Several studies have examined the relation between s-IgA and stressful circumstances ranging from major life events to minor daily events. The findings from these studies were often contradictory, since different experimenters reported different stress-related changes in s-IgA. The effects of stress reduction interventions, such as relaxation and imagery, on s-IgA levels have also been examined. Although these studies indicate that various interventions are associated with increases in s-IgA levels, methodological refinements are needed before more definitive conclusions can be made. The possibility that the relation between stress and s-IgA may be moderated by personality characteristics or mediated by psychological distress was supported in some studies. The review concludes with suggestions for future research.
