Abstract
The purpose of this study was to determine whether there were differences in the side effects of nausea, vomiting, and retching (N, V, and R) between younger ( < 65 years, n = 102) and older ( > or = 65 years, n = 25) persons receiving outpatient chemotherapy. A longitudinal 4-month study was used for the 127 participants recruited from 18 settings. Participants completed two questionnaires (Inventory of N, V, and R and Behavior Checklist) over the course of the study. The pattern between the younger and older patients' N, V, and R subscale scores was consistent in that the younger patients' scores were consistently (except on one occasion) higher than the older patients' scores, but this difference was statistically insignificant. This study furthers our understanding of N, V, and R and has several clinical implications.
