Posttraumatic stress in young children with cancer: Risk factors and comparison with healthy peers.

Abstract

The most commonly occurring childhood cancers are diagnosed during the preschool years; yet limited psycho-oncology research has focused on this developmental time period. The primary objective was to examine rates of posttraumatic stress symptoms (PTSS) in young children with cancer and compare these findings with those of children without a history of serious illness (comparisons). The secondary aim was to examine risk and modifiable factors associated with PTSS. Ninety-seven caregivers of patients (n = 50) and comparisons (n = 47) aged three to six years completed diagnostic interviews for the assessment of PTSD. They also completed a survey measure of PTSS adapted from the Child Behavior Checklist (CBCL-PTSD), along with measures of their child's temperament and their own current psychological functioning. On the CBCL-PTSD, no differences in PTSS were observed between children with cancer and comparisons, although many in both groups appeared at risk, with approximately 34% of children with cancer and 27% of comparisons meeting threshold scores for probable PTSD. However, using a "gold-standard" clinical-interview assessment, only three children in the patient group and no children in the comparison group met diagnostic criteria for PTSD. Parental distress and child temperament were significantly associated with PTSS scores. Findings indicate PTSD is relatively infrequent in children with cancer, and survey measures may overestimate rates of PTSD in young children. However, other emotional or behavioral issues may be present. Ultimately, screening for potential emotional/behavioral concerns in young children with cancer is indicated, and interventions should continue to target caregiver distress.
