M. Amir et al., TYPE OF TRAUMA, SEVERITY OF POSTTRAUMATIC-STRESS-DISORDER CORE SYMPTOMS, AND ASSOCIATED FEATURES, The Journal of general psychology, 123(4), 1996, pp. 341-351
Sixty-six persons with posttraumatic stress disorder (PTSD) exposed to
battlefield experience, civilian terrorism, and work and traffic acci
dents were studied to assess the differential outcome of the various t
ypes of trauma as measured by PTSD core symptoms and associated featur
es of depression, anxiety, interpersonal sensitivity, and somatization
. The participants were assessed on a PTSD scale, Impact of Events Sca
le, and four Symptom Check List subscales. The results showed that the
battle-experience group was more severely affected than the other gro
ups. Time elapsed since the trauma was significantly positively correl
ated to PTSD core sypmtoms and associated features. Only the time elap
sed since the trauma-not the division into type of trauma groups-was s
ignificantly correlated with severity. Education and army rank were fo
und to be protecting variables.
