Developmental Diversity in Symptom Research Involving Children and Adolescents with Cancer

The purpose of this literature review was to evaluate developmental diversity in studies describing physical symptoms in children and adolescents receiving cancer treatment. Developmental diversity was conceptualized as individual differences based on normal stages of human development, including cognitive, psychosocial, and physiologic aspects. Searches of Medline and the Cumulative Index of Nursing and Allied Health Literature identified 53 articles published between January 1986 and November 2006. Most studies addressed symptoms in school-aged children and adolescents; few compared symptoms across age groups. Additional measures are needed to describe younger children's symptoms. Alternate research methodologies may be appropriate to describe their symptom experiences.
