摘要

BACKGROUND: Interest in the role of expectation in the development of nausea and other adverse conditions has existed for decades. The purpose of this study was to examine the effects of manipulating expectations through the administration of placebos and nocebos on nausea and gastric tachyarrhythmia provoked by a rype.addElementToInclusions "Annotation", "Article" End If End If End Function 'doaddElements() ell sizes were too small for meaningful analysis, individuals in the PAN and BAN groups had numerically higher rates of use laxatives as the sole method of purging with respect to other ED groups. Excluding probands (those required to have used vomiting as a compensatory behavior) from the above analyses, 3.6% and 6.6% of participants with PBN and ANBN, respectively, used laxatives-up participants during drum rotation (p < .05). CONCLUSIONS: Inducing negative expectations through nocebo administration reduced nausea and gastric dysrhythmia during exposure to provocative motion, whereas positive placebos were ineffective for preventing symptom development. That manipulation of expectation affected gastric physiological responses as well as reports of symptoms, suggests an unspecified psychophysiological mechanism was responsible for the observed group differences. These results also suggest that patients preparing for difficult medical procedures may benefit most from being provided with detailed information about how unpleasant their condition may become.
