Three research articles in this theme issue address posttraumatic stress
disorder (PTSD). The first, by Krakow and colleaguesArticle, is a randomized trial
of the effectiveness of imagery rehearsal therapy for the treatment of nightmares
among women with PTSD who had experienced sexual assault. Disturbing dreams,
sleep quality, and posttraumatic stress symptoms all improved at study end
point (3- or 6-month follow-up) in women who received imagery rehearsal therapy.
The other 2 studies assessed PTSD in populations that have survived war-related
trauma or mass violence. Mollica and colleaguesArticle, in a 3-year follow-up study
of Bosnian refugees who had been living in a refugee camp in Croatia in 1996,
report that 45% of respondents who had met DSM-IV
criteria for depression, PTSD, or both in the original study continued to
have these disorders; 16% of initially asymptomatic individuals became symptomatic
for psychiatric disorders. In a study of PTSD in postconflict, low-income
countries, de Jong and colleaguesArticle found that the prevalence of PTSD was 37.4%
in Algeria, 28.4% in Cambodia, 15.8% in Ethiopia, and 17.8% in Gaza. In a
commentary, DavidsonArticle emphasizes that PTSD is a worldwide health problem associated
with serious morbidity and reviews the presentation and treatment of this
disorder.
