Here’s the abstract:


Only limited empirical data support the existence of delayed-onset post-
traumatic stress disorder (PTSD).


To expand our understanding of delayed-onset PTSD prevalence and


A cross-sectional, epidemiological design (n = 747) incorporating
structured interviews to obtain relevant information for analyses in a
multisite study of military veterans.


A small percentage of veterans with identified current PTSD (8.3%,
7/84), current subthreshold PTSD (6.9%, 2/29), and lifetime PTSD only
(5.4%, 2/37) met criteria for delayed onset with PTSD symptoms
initiating more than 6 months after the index trauma. Altogether only
0.4% (3/747) of the entire sample had current PTSD with delayed-onset
symptoms developing more than 1 year after trauma exposure, and no PTSD
symptom onset was reported more than 6 years post-trauma.


Retrospective reports of veterans reveal that delayed-onset PTSD
(current, subthreshold or lifetime) is extremely rare 1 year post-
trauma, and there was no evidence of PTSD symptom onset 6 or more years
after trauma exposure.
