This study was aimed to measure the variation of secreted immunoglobulin A's concentration in subjects' saliva as an index of body's immune system reaction after watching aggressive films. Twenty two female students from the University of Tehran participated voluntarily in this study. Participants were randomly allocated in one experimental and one control group. The experimental group watched an aggressive film, while the control group watched a family film. Based on the repeated measurement design, saliva samples were collected in a 5 minute period before and after seeing each film in similar conditions. The samples, then, were analyzed using the Elisa analyzer. The outcome data were analyzed using covariance analysis method. Results revealed a significant increase in the concentration of sIgA after watching aggressive film. This increase was also significant compared to the increase produced by watching the family film in control group. It can be concluded that watching an aggressive film can affect the concentration of sIgA in saliva. This increase in concentration of sIgA is comparable to that of being exposed to an acute stress, or as the other studies showed that of watching horror films.
