PURPOSE
The purpose of this study was to determine the effect of supportive nursing care on the level of knowledge and compliance with sick-role behavior in patients with coronary artery disease after coronary angiography(CAG).
METHODS
A quasi-experimental research was performed with 81 subjects with coronary artery disease who were admitted for CAG to a cardiovascular department. Among the selected subjects, 40 of them were assigned to experimental group and the rest of them were assigned to control group by convenience. Supportive nursing care was implemented twice by a researcher.
RESULTS
1. The mean score of knowledge related to coronary artery disease was higher in the group who received supportive nursing care than that of the control group(t=2.259, p=.027). 2. The mean score of compliance of sick role behavior was higher in the group who received supportive nursing care than that of the control group(t=4.580, p=.001).
CONCLUSION
The supportive nursing care after CAG was effective in increasing the knowledge level and compliance of sick-role behavior in patients with coronary artery disease. Further studies would be recommended to identify long-term effectiveness of supportive care on patients' outcomes.

The purpose of this study was to identify the relationships between self-efficacy, self-esteem, health locus of control and sick-role behavioral compliance in diabetic patients and to identify the influencing factors for sick-role behavioral compliance. The subjects for study were 244 NIDDM patients from 2 hospitals, who were visiting the outpatient clinic in Taegu. Data were collected from Sep. 18.th to Oct. 5th 1996. In data analysis, SPSS/PC+ programs were utilized for descriptives, as well as Pearson correlation coefficient, t-test, ANOVA and stepwise multiple regression. The results were as follows : 1. The average score for the sick-role behavioral compliance was 50.38, for the self-efficacy was 1337.17, for the self-esteem was 27.81, for the internal health locus of control was 28.79, for the chance health locus of control was 20.55, for the powerful others health locus of control was 28.70. 2. The relationships between self-efficacy, self-esteem, health locus of control and sick-role behavioral compliance were significant. Sick-role behavioral compliance were significantly related to self-efficacy(r=0.36, 0.000), to self-esteem (r=0.19, p=0.001), to internal health locus of control(r=0.28, p=0.000), to powerful others health locus of control (r=0.28, p=0.000). 3. In the relationship between general characteristics and sick-role behavioral compliance there were significant differences in a job (t=-2.01, p=0.045), experience of diabetic education(t=2.32, p=0.022). 4. Stepwise multiple regression analysis was performed to identify the influencing factors for sick-role behavioral compliance. Self-efficacy, self-esteem, internal health locus of control, having or not having a job and experience of diabetic education accounted for 24% of the variance in sick-role behavioral compliance. The self-efficacy was the most predictive factor (R2=13%) followed by internal health locus of control, job, self-esteem and experience of diabetic education. The results suggest that self-efficacy is an important variable in the compliance of diabetic patients. For improvement in sick-role behavioral compliance nursing intervention needs to be directed at promoting self-efficacy.
