Emotional Crying, Depressed Mood, and Secretory Immunoglobulin A

Abstract

The relationship between emotional crying and secretory immunoglobulin A (S-IgA) in whole saliva was examined. Previous research had indicated that lower S-IgA was associated with crying. Similar results were found in the present study. Depressed mood was not associated with S-IgA.
