A Systematic Review of Interventions with Siblings of Pediatric Cancer Patients

ABSTRACT

PURPOSE: The purpose of this study was to review interventions available to nurses caring for siblings of children with cancer. METHODS: Searches of CINAHL, MEDLINE, PubMed, EMBASE, and RISS identified ten intervention studies published from January, 2000 to November, 2016. RESULTS: Ten studies on interventions for siblings of pediatric cancer patients were identified as follows 4 included camps, 4 included support groups, and 2 provided individual interventions. Theoretical frameworks were mainly cognitive behavioral theory and most studies were led by psychologists and multidisciplinary teams. The purpose of the interventions was primarily enhancing psychosocial adjustment. Siblings' fear of disease, self-esteem, and social support were improved significantly after the interventions. Findings were inconsistent with regard to depression, anxiety, behavioral problems, post-traumatic stress, health-related quality of life, and siblings' perceptions of the illness. CONCLUSION: Study findings showed the potential for enhancing emotional and behavioral outcomes in siblings of children with cancer. However, the number of studies was very small, and several methodological limitations were identified. In the future, more randomized controlled trials with larger samples are needed to extend the evidence base. Moreover, future research should identify sibling's characteristics and circumstances most likely to bring benefits to the siblings.
