Sensitizing effects of pretreatment measures on cancer chemotherapy nausea and vomiting.

This study explored the sensitizing effects of pretreatment assessment on posttreatment chemotherapy nausea and vomiting and the interactive effects of personal dispositions for information seeking. Seventy oncology outpatients were recruited from oncology waiting rooms prior to receiving scheduled chemotherapy. Half of the patients were asked to complete an inventory about the severity of side effects that they had experienced following their most recent treatment session (experimental condition) and half were asked to complete an inventory concerning parking conditions at the treatment facility (control condition). All patients were also asked to complete the Miller Behavioral Style Scale (MBSS) and to later rate the severity of their side effects (between 36–48 hr following treatment). Based on the MBSS scores, patients were then divided into information seekers (monitors) and information avoiders (blunters). Overall, patients in the experimental condition rated the severity of their nausea as more severe than the control patients. In addition, patients who preferred a monitoring coping style experienced a significantly higher incidence rate and longer episodes of nausea than patients who preferred a blunting style. The methodological implications of these results for data collection and the assessment of side effects associated with aversive medical procedures are discussed.
