Data were collected on 10 newswriters in a newspaper's newsroom. These incl
uded self-reported stress ratings and saliva samples for secretary immunogl
obulin A (IgA) analysis. The stress ratings and saliva samples were taken i
nitially and after three 30-min, periods. The first time period was a basel
ine measure and involved the workers engaging in their usual tasks. At Time
2 music was presented for 30 min, while workers engaged in their normal ac
tivities. At Time 3 workers resumed their normal duties. Findings showed an
increase in IRA that was not statistically significant, a reduction in str
ess during the music period that was statistically significant, and a stati
stically significant negative correlation between stress and IgA.
