This study investigated concordance between male Vietnam veterans' and
their female partners' reports of veterans' posttraumatic stress diso
rder (PTSD) symptoms. Fifty male Vietnam combat veterans and their par
tners rated the severity of their own PTSD symptoms. Also, partners ra
ted the severity of veterans' symptoms. Results indicated modest level
s of agreement in reports of symptom presence/absence. Partner ratings
of veterans' PTSD severity were positively correlated with veteran re
ports and partners' own self-reported PTSD symptoms. After controlling
for veterans' self-reported symptoms, partners' symptoms significantl
y predicted their estimates of veterans' avoidance symptoms, but not v
eterans' reexperiencing or hyperarousal symptoms. Theoretical and prac
tical implications of these findings are discussed.
