Full and partial posttraumatic stress disorder among World War II prisoners of war

BACKGROUND: The aim of the study is to evaluate the frequency and characteristics of full and partial post-traumatic stress disorder (PTSD) among 66 World War II Nazi prisoners of war, some of whom had been deported to death camps. METHODS: The Structured Clinical Interview for DSM-IV was used to assess the presence of PTSD and major depression. The Dissociative Experiences Scale and the 58-item version of the Hopkins Symptom Checklist were also administered. Partial PTSD was defined as the presence of at least one symptom in each of the clusters defined by DSM-IV. RESULTS: Forty-eight percent of the subjects have a partial PTSD, while 20% reported the full syndrome. When compared to subjects with full PTSD, those with partial PTSD showed a significantly lower frequency of comorbid depression and lower levels of psychological distress, as measured by the Symptom Checklist. No differences were found with regards to dissociative symptoms and help-seeking. CONCLUSIONS: The problem of definition of PTSD partial syndromes deserves more attention in the literature.
