Alpha amylase and cortisol by collection timepoint.

	M (SD)
Hormone	T1	T2	T3
Alpha Amylase in U/ml	46.5 (34.5)	76.8 (56.5)**	75.1 (76.5)*
Cortisol in μg/dl	0.33 (0.31)	0.27 (0.24)	0.25 (0.19)

Note: SAA reactivity is indexed by the difference from T1 to T2 samples, due to the rapid increase in sAA concentrations in response to a stressor. Cortisol reactivity is indexed by the difference from T2 to T3 samples, due to the approximately 20 min delay for the increase in cortisol concentrations in response to a stressor. There was a significant increase in sAA from baseline to the time of trauma discussion, which was maintained at T3. The maintained increase in sAA at T3 reflects the content of the interview at that point; most participants still were responding to interview questions about trauma symptoms related to the index event. There was no increase in cortisol.
