Note. PTSD = Posttraumatic stress disorder. All post hoc two-way comparisons were significant at p < .001 except those between the two partial PTSD groups (partial PTSD-2AV and partial PTSD-1AV).
a
PTSD-2AV = Fully meets PTSD criteria B and D, but only has two avoidance symptoms.
b
PTSD-1AV = Fully meets PTSD criteria B and D, but only has one avoidance symptom.
