Cancer-related traumatic stress reactions in siblings of children with cancer

The purpose of this study was to explore cancer-related posttraumatic stress (PTS) reactions in siblings of children with cancer including prevalence, common symptoms, comorbidity with anxiety and depression, and gender-and age-related patterns. A total of 125 children (63 girls) between the ages of 8 and 17 (M = 12.4; SD = 2.9 years) with a brother or sister with cancer, diagnosed 4 to 38 months prior to the study (M=1.3 years; SD=6.7 months), completed the Child PTSD Symptom Scale (CPSS), Revised Children's Manifest Anxiety Scale, and Child Depression Inventory-Short Form. Over half of the sample (60%) scored in the moderate to severe range for PTS and 22% fulfilled full criteria for PTSD based upon CPSS responses. Nearly 75% reported "Feeling upset when you think about or hear about the cancer," and "Trying not to think about, talk about, or have feelings about the cancer." Over 60% reported arousal symptoms. PTS symptoms reportedly interfered with functioning for 75% of the sample and co-occurred with anxiety and depressive symptoms. Gender and age-related patterns were not found. Siblings of children with cancer experience cancer-related PTS reactions and greater attention should be paid to ameliorating their cancer-related distress with empirically based treatments.
