Abstract
The consequences of a nurse's negative evaluation of a blood pressure reading. Implications for the etiology of white-coat hypertension. The aim of this study was to show how a nurse's negative evaluation of a blood pressure (BP) reading can cause an increase in BP in the following reading. Twenty-five subjects with normal pressure who had been informed that they were to participate in an epidemiological BP study took part and they were divided into two groups. After taking the first BP reading, participants from the experimental group were informed that their pressure was normal but high for their age, whereas those in the control group were told that their pressure was normal for their age. The results showed that this comment caused a significant increase in the diastolic BP of the experimental group. The theoretical and clinical implications of this reaction are discussed in relation to the phenomenon known as White-Coat Hypertension from the perspective of the theory of incubation.
