The purpose of this study was to determine the factors of anxiety perceived by patients given the sensation information. The ultimate goal of the re-search was to provide the data to help nurses to utilize: the systematic nursing intervention to pre-vent or reduce the patient´s anxiety.
A total of forty five subjects with coronary angiography were selected at two University hospitals in Seoul.
In this study the randomized control group prepost test design was employed based on the educational material for the cardiac catheterization developed by kim(1989).
The nursing intervention including sensation in-formation was conducted in the experimental group. State Trate Anxiey Inventory deviced by Spielberger(1976) was used to measure the anxiey as the dependent variable. Other dependent variables were the subjective perception modified by the investigator, the blood pressure and pulse.
Data were analyzed using ttest and x2test to determine similarity between the experimental and control group as well as between the two hospitals.
The hypothesis was examined using ttest, Repeated Mesures of ANOVA and Pearson Correlation Coefficient.
The results of this study are summerized as follows :
1. The first hypothesis was accepted ; State anxiety was low at the experimental group as compared to the control group(t=4.36, df=43, P=.00).
2. The second hypothesis was accepted ; There was no statistically significant difference of the blood pressure across three phases ( before, during and after test)between the experimental and control group. (systolic BP ; experimental group ; F=.10, P=.90, control group ; F=4.50, P=.02) (diastolic BP , experimental group ; F=.77, P=.47, control group ; F=4.14, P=.02).
3. The third hypothesis was rejected ; There was a statistically significant differance of the pulse across three phases(before, during and after the test) between the experimental group and control group. (experimental group ; F=2.54, P=.09, control group ; F=2.00, P=15).
4. The forth hypothesis was accepted : The subjective perception during the test was low at the experimental group as compared to the control group(t=6.01, df=43, P=.00).
5. The fifth hypothesis was accepted ; There was a statistically significant relationship between the State anxiety and the subjective perception(r=.5388, P=.000).
This study has three important findings. The first finding was that State anxiety among patients given the sensation information was reduced. The second finding was that there was no variation of the blood pressure across the three phases (before, during and after the test) among patients given the sensation information. The third finding was that the subjective perception during the test among patients given the sensation information was low as compared to the control group.
This findings suggested the need of nursing intervention to prevent and reduce the anxiety experienced by patients.
The nursing intervention for patients given the test should include the information on the test procedure and apparatus as well as the accurate sensation.
This study shows that the sensation information has no influence on the phases as the indicator of the anxiety experienced by patients. There is a need of research on the nursing intervention with repeated measurement controlling the clinical situation and personal factor.
