Prevalence and predictors of posttraumatic stress disorder in adult survivors of childhood cancer: A report from the Childhood Cancer Survivor Study

CRA10002 Background: This study examined prevalence and demographic- and disease-related correlates of posttraumatic stress disorder (PTSD) among 6,542 adult childhood cancer survivors and 368 siblings from the Childhood Cancer Survivor Study. Methods: Subjects were dichotomized based on full PTSD criteria, using the Foa PTSD self-report measure to assess posttraumatic stress symptoms of intrusion of unwanted memories, avoidance of event reminders, and increased startle response, and the Brief Symptom Inventory-18 and the SF-36 subscale, role limitation due to emotional health, to evaluate clinical distress or impaired function. A self-report questionnaire provided demographic information and medical abstraction provided cancer reatment data. Multivariable generalized linear models were used to compare prevalence of PTSD among cancer survivors to siblings and to examine relationships between PTSD and demographic and disease-related factors. Relative risks (RR) were calculated based on a Poisson distributi...
