Epstein-Barr Virus (EBV) antibody titer has been shown through meta-analysis to be “the most consistent and significant correlate of psychosocial stressors,” worldwide. Stress's negative impact on the immune system can apparently persist over several years of repression or suppression of emotion. In one study, more than forty years after the Holocaust, the act of verbalizing the experience resulted in significantly fewer doctor's visits and fewer reports of health problems among survivors during the next year, particularly for those whose narratives used the most emotional words. Use of emotional words may reflect interpersonal coping style, which apparently moderates the effect of disclosure: sensitizers who are quick to express negative feelings demonstrate lower skin conductance level and higher heart rate than repressors who tend to deny negative feelings. Based on such findings, these authors examined changes in EBV antibody titer in repressors and sensitizers for either oral or written disclosure of a traumatic or trivial event. Using undergraduates, they found that oral disclosure of a stressful event resulted in a greater decrease in EBV antibody titer than written disclosure of a stressful event, and that disclosure of a stressful event was more successful at lowering EBV antibody titer than disclosure of a trivial event, which had no effect. Repressors (categorized using the Millon Behavioral Health Inventory) were at a disadvantage compared to either sensitizers or subjects who were neither sensitizers nor repressors, although there was no apparent
