Measuring nausea and vomiting in adolescents: a feasibility study.

Several instruments have been developed over the years to assess nausea and vomiting in adults, yet their validity and reliability with children are unknown. It would be useful to have an instrument simple enough for use with the vast majority of children (regardless of age and developmental level) to provide a consistent way to measure nausea and vomiting throughout the pediatric population. The purpose of this study was to test the feasibility of using one or more adult instruments with adolescents. A feasibility study was conducted using three existing instruments designed to measure nausea and vomiting. A convenience sample of 10 adolescents between the ages of 13 and 18 years receiving chemotherapy was recruited at a Midwestern children's hospital oncology unit. The adolescents were assessed using instruments starting before and continuing after one individual round of chemotherapy. A qualitative analysis demonstrated significant problems in implementing all three instruments with adolescents. Future research should concentrate on original instrument development based on qualitative studies that seek to understand the unique experience of a child with cancer.
