Siblings of children with cancer: a review of the literature.

Research on siblings of children with cancer during the past 40 years has clearly shown that the childhood cancer experience is a stressor that may increase subjective feelings of stress by well siblings and in some cases lead to decreased psychosocial competencies and increased psychopathologies. Research has expanded from identifying psychosocial problems experienced by the sibling after the patient's death to identifying stressors during the illness experience. More recent studies have been targeted at identifying what action siblings take to cope with the stressors imposed since the cancer diagnosis and have addressed what interventions pediatric oncology nurses use in clinical practice to provide support to siblings of children with cancer. The current state of this body of literature, a review of 18 studies, is presented in this article along with a critique of the research studies and suggestions for future research.
