The purpose of this study is to examine the relation between cognitive style and measurement error of blood pressure. Subjects were 117 students from School-nursing course, Faculty of Education, Hirosaki University.
Subjects were classfied into 4 groups on the basis of their reaction times and errors in Matching Familiar Figures test. "FA" group has fast reaction time and accurate performance, "FI" group has fast and inaccurate reaction, "SA" group has slow and accurate reaction, and "SI" group has slow and inaccurate reaction.
Measurement error was obtained from the difference between stethoscopy and "Pulse Wave and Korotkoff Sound recorder" (automatic sphygmomanometer).
The results were as follows:
1. Measurement error of both Inaccurate groups was larger than both Accurate groups in systolic pressure, and the error of both Fast groups was larger than both Slow groups in diastolic pressure. Therefore, it was concluded that measurement error by FI group seemed to be larger than by SA group.
2. Measurement error of systolic pressure was larger than diastolic presure in all groups.
3. Compared with values obtained by the recorder, every group overestimated both the systolic and diastolic pressures. FA group in systolic pressure and SI group in diastolic pressure had more deviation in decision than the other groups.
4. Measurement error of systolic pressure was large in overestimation and small in underestimation in comparison with recorder-measured values.
