Background. Ischemic heart disease results from athesclerotic changes of the coronary artery. These changes are aggravated by hypercholesterolemia, smoking, obesity, lack of exercise, coronary-prone personality, and stress. Because these risk factors affect not only the prevalence of the ischemic heart disease but also recurrence of the disease, cardiac rehabilitation programs were introduced to help patients with ischemic heart disease reduce risk factors. Diverse cardiac rehabilitation programs are needed to motivate participation in cardiac rehabilitation and to enhance patients' quality of life. Objectives. To examine the effect of a self-efficacy promoting cardiac rehabiltation program on self-efficacy, health behavior and quality of life of patients with ischemic heart disease. Methods. Data were collected from 45 hospitalized ischemic heart disease patients. Medical records were reviewed to obtain demographic and clinical characteristics. Data regarding self-efficacy, health behavior, and quality of life were obtained from interviews using structured questionnaires. The nonequivalent control group non-synchronized design was used to conduct this study. One session of conventional group education was given to patients in the control group while they were in the hospital. Patients in the experimental group participated in a newly developed cardiac rehabilitation program. It focused on strengthening self-efficacy with four self-efficacy sources-performance accomplishment, vicarious experiences, verbal persuasion and physical status using two individualized in-hospital education sessions and four weekly telephone counseling follow-up calls after discharge. Results. Four weeks after discharge, the increment of total self-efficacy score was significantly higher in the experimental group than in the control group (p<.0l). There was also a significant difference in the total quality of life scores increments between the two groups (p<.0l). However, no significant changes were noted in the increments of total health behavior scores between the two groups. Conclusion. A cardiac rehabilitation program focusing on promoting self-efficacy was effective in improving self-efficacy, and quality of life of patients with ischemic heart disease.

Purpose: The purpose of this study was to examine body composition and dietary self-efficacy in nursing students. Methods: The study was a descriptive, correlational study with a convenience sample of 197 female nursing students. This study was conducted from April 1st to May 31th in 2015. SPSS 21.0 program was used for data analysis. Results: The average of body protein was $7.90{\pm}1.17kg$ and normal range was 33%. A BMI's average was $21.02{\pm}2.94kg/m^2$ and 62.9 fell into standard range. The average of dietary self-efficacy of subjects was $3.42{\pm}0.53$. The subjects performed intense physical activities during three or more days had higher body protein (F=5.89, p=.003), body minerals (F=6.15, p=.003) and body-efficacy (F=4.13, p=.017) but remarkably lower body fat (F=4.04, p=.019). There is no noticeable correlation of body composition with dietary self-efficacy. However, it is obvious that each category of body composition had a significant positive correlation. Conclusion: This study demonstrated that students who were inclined to overeat had higher body protein, body minerals, body fat, and BMI. Students performed intense physical activities had high body protein, body minerals, and dietary self-efficacy, whereas they had low body fat. Each entry between the body composition had a significant positive correlation.

The purpose of this study is to develop self-efficacy promotion program and to test its effects on self-efficacy, self-care, physiologic index of hemodialysis patients after applying this program to them. Preliminary study was carried out to identify the levels and types of self-care, self-efficacy of hemodialysis patients. To develop self-efficacy promoting program, several discussions with nursing professors and nurse specialists on hemodialysis patients were made after in-depth literature review on the area. Through these processes, the self-efficacy promoting program including 20 minutes long videotape and other counciling documents were completed. This videotape consisted of specific self-care techniques for hemodialysis patients including management of fistula, measurement of blood presure and body weight, special diets, medications, exercise and rest, management of physical problems and social adjustment. Two group equivalent pre and post test quasai-experimental research design was used in this study. The total subjects were 34 hemodialysis patients who received hemodialysis three time per week at 1 university hospital. Seventeen experimental group subjects were matched with control group subjects in sex and age. Data were analysed with the SPSS window program. Homogeniety between experimental and control group pretest data was tested by x$^2$ and t-test. There were no significanct differences in general characteristics, illness history, specific self-efficacy and self-care between the two groups. The differences of general self-efficacy of two groups were tested with the Repeated Measure ANCOVA because of significant differences of pretest data of general self efficacy between two groups. The differences of self-efficacy and self-care of two groups were tested with Repeated Measure ANOVA and the differences of physiologic indecies including blood potassium level and blood phosphorus level and interdialytic weight gain were tested by t-test. The results were as follows: 1. There was no significant difference in general self-efficacy between the two groups over four different time, and no interaction by groups and by time. 2. There was significant difference in specific self-efficacy between the two groups over four different time, and interaction by groups and by time. 3. There was significant difference in self-care between the two groups over four different time, and interaction by groups and by time. 4. There were no significant differences of blood potassium level and blood phosphorus level, but there was significant difference of interdialytic weight gain between the two groups. From the results above, it can be concluded that the self-efficacy promotion program for hemodialysis patients was effective to improve degree of specific self-efficacy and self-care and to decrease interdialytic weight gain. Considering results, the followings are recommended: 1) Repeated studies are needed for another hemodialysis patients. 2) This program can be used for improving degree of self-efficacy and self-care of hemodialysis patients by nurse practitioner and nurse educator.

Purpose: The purpose of this study was to examine effects of a dietary program based on self-efficacy theory on dietary adherence, physical status and quality of life (QoL) in hemodialysis patients. Methods: A non-equivalent control group pre-post test design was used. The intervention group received the dietary program for 8 weeks from August 4 to September 26, 2014. The control group received only usual care. Results: ANCOVA showed that dietary adherence (F=64.75, p <.001) was significantly different between the two groups. Serum albumin (F=12.13, p =.001), interdialytic weight gain (F=56.97, p <.001), calories (F=15.80, p <.001) as physical status indices were significantly different, but serum potassium (F=2.69, p =.106) and serum phosphorus (F=1.08, p =.303) showed no significant difference between the two groups. In terms of health-related QoL, the physical component scale (F=10.05, p =.002) and the mental component scale (F=16.66, p <.001) were significantly different between the two groups. In addition, in terms of diet related QoL, diet level (F=35.33, p <.001) and satisfaction level (F=15.57, p <.001) were significantly different between the two groups, but dietary impact level (F=1.23, p =.271) was not significantly different. Conclusion: Findings show that the dietary program based on self-efficacy theory is an effective nursing intervention program to improve adherence to diet, and to maintain physical status and QoL for hemodialysis patients.

BACKGROUND/OBJECTIVES: Childhood obesity has increased in recent decades in Korea. This study was designed to examine differences in the eating habits, physical activity (PA), nutrition knowledge, and self-efficacy of children by obesity status. SUBJECTS/METHODS: Subjects were 5th-grade children from 70 elementary schools in 17 cities nationwide. Two-stage stratified cluster sampling was employed. Survey questionnaire included items related to general characteristics, eating habits, PA, nutrition knowledge and self-efficacy. Excluding incomplete responses, 3,531 data were analyzed using SPSS. Subjects were categorized into overweight obesity (OW) and normal weight (NW) groups based on body mass index percentiles for age by sex. RESULTS: A total of 21.5% of subjects was overweight or obese. There were significant differences in gender, perceived stress, perception of body shape, body satisfaction, and interest in weight control between the OW and NW groups (P < 0.001). With respect to eating habits, the OW group ate breakfast (P < 0.05) and snacks (P < 0.01) less frequently, ate bigger meals (P < 0.001), and demonstrated less desirable behaviors during meals (P < 0.05 in boys) compared to the NW group. The OW group participated in less PA than the NW group, especially boys. OW boys spent less time walking during weekdays (P < 0.05) or the weekend (P < 0.001), spent more time being sedentary during weekdays or the weekend (P < 0.001), and exercised a fewer number of days (P < 0.01). For girls, the OW group spent more time being sedentary during the weekend (P < 0.01) and exercised a fewer number of days by walking or bicycle riding (P < 0.05) than the NW group. Nutrition knowledge was not significantly different between the OW and NW groups. Self-efficacy (P < 0.01 in boys), especially PA self-efficacy (P < 0.01), was significantly lower in the OW than NW group. CONCLUSIONS: This study revealed differences in eating habits, PA, and self-efficacy between OW and NW children. Obesity management programs for children need to focus on increasing self-efficacy, modifying eating habits, and increasing PA.

Purpose: The purpose of this study was to examine their levels of knowledge of the kidney, self-efficacy, and kidney function in pre-dialysis patients with chronic renal insufficiency. Methods: A total of 142 pre-dialysis patients with chronic renal insufficiency were recruited from a nephrology clinic of a hospital in Korea. Participants' knowledge of the kidney, self-efficacy, and kidney function were measured, and the correlations between these factors were computed. Results: The levels of knowledge of the kidney were moderate, with a mean score of $12.30{\pm}5.35$. Knowledge level was significantly correlated with age, education level, occupation, income, physical symptoms, and information resources (p<.05). The mean score for self-efficacy was $6.06{\pm}2.00$. Self-efficacy was significantly associated with patients' age, education level, occupation, income, cigarette use, and information resources (p<.05). The mean score for kidney function was $35.66{\pm}18.68mL/min/1.73m^2$. Kidney function was significantly correlated with use of medications and drinking behavior (p<.05). Knowledge of the kidney was significantly correlated with self-efficacy (r=.31, p<.001), but not with kidney function. There was a significant correlation between self-efficacy and kidney function (r=.30, p<.001). Multiple regression analysis revealed that self-efficacy and drinking behavior accounted for 11% of the variance in kidney function of pre-dialysis patients with chronic renal insufficiency. Conclusion: Nursing interventions are necessary to increase self-efficacy among pre-dialysis patients with chronic renal insufficiency in order to maintain their kidney function.

Purpose : The purpose of this study was to investigate the depression, self-efficacy, and stress level of middle-aged women and to identify the factors affecting on stress, and to provide base line data for the development of nursing intervention for stress reduction of middle-aged women. Methods : Participants were 200 middle-aged women aged 40 to 60 who live in Seoul and Gyeonggi Province. Data collection period was from March 1, 2019 to April 15. In this study, the questionnaire of life events-stress, depression scale, self-efficacy was used. Data were analyzed by average, standard deviation, minimum, maximum, correlation and regression using the SPSS Program 21.0. Results : The results of this study, the correlation between depression, self-efficacy and stress in middle-aged women, depression and self-efficacy (r=-.264, p<.001), self-efficacy and stress (r=-.279, p<.001) had a significant negative correlation, depression and stress (r=.268, p<.001) had a significant positive correlation. Depression and self-efficacy were the factors affecting the stress of middle-aged women. Depression was β =.207 (p<.001) and self-efficacy β =-.222 (p=.003). Depression had the greatest influence on stress, followed by self-efficacy. Conclusion : Middle-aged women are an important time to prepare for a successful old age. Considering that the current middle-aged women are the subjects of the future aging society, their physical, psychological, and social problems are very important in preventing the elderly problems of the aging society. Therefore, effective nursing interventions should be developed that to reduce the depression and stress in middle-aged women and to improve self-efficacy and improve the quality of life of middle-aged women.

Many arthritis patients experience physical and psychological impairments. Two hundred and three patients were examined to identify the relationships between the variables such as pain, ADL depression, self-efficacy and the effect of self-efficacy on pain, ADL and depression. It was found that ADL is significantly negatively related to depression and pain, and positively related to self-efficacy. Pain was significantly negatively related to self-efficacy, and positively related to depression and ADL. Then stepwise multiple regression was performed to Identify the variables to predict ADL, pain and depression. Self-efficacy predicted negatively depression and positively ADL. Depression predicted positively pain. So it was revealed that self-efficacy decreased pain indirectly by influencing depression. Also Pain predicted negatively ADL. ADL was predicted directly by pain and self-efficacy. So it is suggented that nursing intervention improving self-efficacy would be useful for patients with depression, pain, and ADL limitation. Moreover, these subjects gained 44 score in depression which means severe depressed state. So it is very important to implement nursing intervention to increase self-efficacy. Recommendations for future research was suggested.

Purpose: The purpose of this study was to develop a multi-disciplinary self-management intervention based on empowerment theory and to evaluate the effectiveness of the intervention for older adults with chronic illness. Methods: A randomized controlled trial design was used with 43 Korean older adults with chronic illness (Experimental group=22, Control group=21). The intervention consisted of two phases: (1) 8-week multi-disciplinary, team guided, group-based health education, exercise session, and individual empowerment counseling, (2) 16-week self-help group activities including weekly exercise and group discussion to maintain acquired self-management skills and problem-solving skills. Baseline, 8-week, and 24-week assessments measured health empowerment, exercise self-efficacy, physical activity, and physical function. Results: Health empowerment, physical activity, and physical function in the experimental group increased significantly compared to the control group over time. Exercise self-efficacy significantly increased in experimental group over time but there was no significant difference between the two groups. Conclusion: The self-management program based on empowerment theory improved health empowerment, physical activity, and physical function in older adults. The study finding suggests that a health empowerment strategy may be an effective approach for older adults with multiple chronic illnesses in terms of achieving a sense of control over their chronic illness and actively engaging self-management.

The purpose of the study was to find the effect of play-using assertion training program on elementary school children's self-expression, interpersonal relationship and self-efficacy. For the purpose of the study, the researcher sets hypotheses as follows. Hypothesis I : The play-using assertion training program has significant effect in elementary school children's self-expression. Hypothesis II : The play-using assertion training program has significant effect on elementary school children's interpersonal relationship. Hypothesis III: The play-using assertion training program has significant effect on elementary school children's self-efficacy. To verify these hypotheses, the researcher selected 10 students of 4th grade in C elementary school as a experimental group, and 11 students of 4th grade in O elementary school as a controlled group. Both schools are located at Boryoung, Chungnam. In the experimental group, the researcher administered the play-using assertion training program once a week for ten weeks. The play-using assertion training program are made by the researcher based on Jeon(1985) and Byoun and Kim(1980). To measure self-expression, the scale of self-expression made by Byoun & Kim(1980) was used. To measure interpersonal relationship, the scale of relationship change made by Schlin and Guerney(1971) was used. The scale was translated by Lee and Moon(1980). To measure self-efficacy, the scale of self-efficacy made by Han(2002) was used. The scale is based on Kim and Cha(1996) and Kim(1997). The result of the study is that the play-using assertion training program gives positive effects on students' self-expression, especially in physical area. Second, the play-using assertion training program gives positive effects on students' interpersonal relationship, especially in satisfaction, communication and friendliness. Third, the play-using assertion training program generally does not give positive effects on students' self-efficacy, but give significant effects on confidence and self-control efficacy which are sub-areas of self-efficacy.
