The Effects of Guided Imagery on Stress, State Anxiety, Test Anxiety and Core Basic Nursing Skill Performance Score of Undergraduate Nursing Students / 한국간호교육학회지

This study examined the effects of guided imagery on stress, state anxiety, test anxiety and core basic nursing skill performance score of undergraduate nursing student. Methods: An equivalent control group pretest-posttest design was utilized. A total of 45 senior nursing students were randomly assigned to either an intervention group to receive guided imagery, or a control group (experimental group=23 students, control group=22 students). The guided imagery was provided via audio files to the intervention group for eight minutes, once a day for five days. The pretest was given before the intervention to measure variables for both groups, and the posttest was performed immediately afterward and three days after the intervention. Results: Significant differences were found between the two groups in stress ((F=4.94, p=.012), state anxiety (F=5.99, p=.005), and basic core nursing skill performance scores (Z=-2.45, p=.015). Conclusion: Guided imagery for nursing students has been identified as effective for stress, state anxiety, and basic core nursing skill performance scores. Guided imagery can be used as an effective intervention before performance tests. These study results can provide useful data for nursing education.

Factors Affecting Job Stress of Pediatric Nurses: Focusing on Self-Efficacy, Emotional Labor, Pediatric Nurse-Parent Partnership

PURPOSE: In this study self-efficacy, emotional labor, pediatric nurse-parent partnership and job stress of pediatric nurses were examined. Factors affecting job stress of pediatric nurses were also investigated. METHODS: The study was done between June and September 2014, with a convenience sample of 145 nurses from 3 advanced general hospitals, 5 general hospitals and 2 children's hospitals. Research data were collected via questionnaires and analysed using SPSS version 18.0. RESULTS: Average levels of self-efficacy, emotional labor and job stress were similar to other general nurses and the average level of pediatric nurse-parent partnership was also similar to other pediatric nurses. Job stress of pediatric nurses showed a positive correlation with emotional labor and negative correlations with self-efficacy and pediatric nurse-parent partnership. The most significant factor affecting job stress in pediatric nurses was emotional labor (beta=0.372, p<.001). The combination of emotional labor, pediatric nurse-parent partnership and self-efficacy accounted for 25.4% of job stress in pediatric nurses. CONCLUSION: These results suggest that nursing management strategies to decrease emotional labor and improve pediatric nurse-parent partnerships and self-efficacy are critical to decrease job stress for pediatric nurses. Continued development of nursing management interventions to decrease job stress in pediatric nurses is suggested.

The Mediating Effect of Self-efficacy in the Relationship between Diabetes Knowledge and Health Promoting Behaviors: Focus on Gender Differentiation / 한국간호교육학회지

PURPOSE: This study examined diabetes knowledge, self-efficacy, and health promoting behaviors, and investigated factors affecting health-promoting behaviors of middle-aged people. METHODS: From August to September 2014, a convenience sample of 264 subjects was recruited from B city and G province. The data analysis was done by chi2 test, t-test, Pearson's correlation coefficient, and stepwise multiple regression. RESULTS: Diabetes knowledge was 11.3+/-3.63 in men and 12.7+/-3.74 in women. The average levels of self-efficacy and health promoting behaviors of subjects were similar with other middle-aged individuals. Diabetes knowledge, self-efficacy, and health promoting behaviors had a positive correlation with each other in both men and women. To test the mediating effect of self-efficacy in the relationship between diabetes knowledge and health promoting behaviors, a Sobel test was performed and Z-scores of 3.698(p<.001) in men and 2.748(p=.006) in women were obtained. CONCLUSION: Diabetes prevention education is recommended for the middle-aged community. When developing diabetes prevention program for middle-aged people, such programs should consider self-efficacy, especially in women.

Structural Equation Modeling on Healthy Menopausal Transition

PURPOSE: This study was designed to construct and test structural equation modeling on healthy menopausal transition in middle-aged women in order to identify variables affecting healthy menopausal transition. METHODS: Participants, 276 women, 45 to 60 years of age, with menopausal symptom score higher than 5 on the Korean version of Menopause Rating Scale, were recruited in three cities and one county of Gyeongnam Province. Research data were collected via questionnaires and analysed using SPSS version 18.0 and AMOS version 20.0. RESULTS: After confirmatory factor analysis, one of the observed variables was excluded due to relatively low factor loading. The model fit indices for the hypothetical model were suitable for the recommended level: GFI=.93, CFI=.92, RMSEA=.05. Self-efficacy, self-differentiation, and menopausal symptoms explained 67.7% of variance in menopausal transition, and self-differentiation was the most influential factor for menopausal transition. Self efficacy and menopausal symptoms explained 9.6% of variance in menopausal management, although "menopausal symptoms" was not significant. CONCLUSION: These results suggest that nursing interventions to improve self-differentiation, self efficacy, menopausal management and decrease menopausal symptoms are critical for healthy menopausal transition in middle-aged women. Continued development of a variety of community-based nursing interventions to facilitate healthy menopausal transition is suggested.

Factors Affecting Nurse's Health Promoting Behavior: Focusing on Self-efficacy and Emotional Labor / 한국직업건강간호학회지

PURPOSE: This study examined self-efficacy, emotional labor, and health promoting behaviors. It also investigated factors affecting health promoting behaviors of nurses working for tertiary and general hospital. METHODS: Between June and July 2013, a convenience sample of 233 subjects was collected from 2 tertiary hospitals and 4 general hospitals. The data analysis was done with ANOVA, t-test and stepwise multiple regression. RESULTS: Emotional labor of the subjects was slightly lower than that of other nurses and the average level of health promoting behaviors was lower than the median. Health promoting behaviors were differentiated by education, hospital type, and monthly income. Self-efficacy showed positive correlation with HPLP-II, but emotional labor showed negative correlation with self-efficacy and HPLP-II. The most significant factor affecting health promoting behaviors was self regulation(16.3%). The combination of self regulation, attentiveness to required display rules, BSN, preference to task difficulty, and monthly income(> or =300) accounted for 25.4% of health promoting behavior. Attentiveness to required display rules was a negative factor of HPLP-II. CONCLUSION: When developing health promotion programs for nurses, self-efficacy should be considered and further research is needed to identify mediating variables between emotional labor and health promoting behaviors.

2,3,7,8-Tetrachlorodibenzo-P-Dioxin Induced Cell-Specific Drug Transporters With Acquired Cisplatin Resistance in Cisplatin Sensitive Cancer Cells

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) can induce drug transporter genes such as the ATP-binding cassette G member 2 (ABCG2), which contributes to multidrug resistance. We investigated the effect of TCDD pretreatment on drug transporters induction from cancer cells of various origins. Cell viabilities after treatment of cisplatin were measured to evaluate acquiring cisplatin resistance by TCDD. Acquring cisplatin resistance was found only in cisplatin senstivie cancer cells including gastric SNU601, colon LS180, brain CRT-MG and lymphoma Jurkat cells which showed a significant increase in cell viability after combined treatment with TCDD and cisplatin. High increase of ABCG2 gene expression was found in SNU601 and LS180 cells with a mild increase in the expression of the ABCC3, ABCC5,and SLC29A2 genes in SNU601 cells, and of major vault protein (MVP) in LS180 cells. The AhR inhibitor kaempferol suppressed the upregulation of ABCG2 expression and reversed the TCDD-induced increase in cell viability in LS180 cells. However, in CRT-MG cells, other transporter genes including ABCC1, ABCC5, ABCA3, ABCA2, ABCB4, ABCG1, and SLC29A1 were up-regulated. These findings suggested the acquiring cisplatin resistance by TCDD associated with cancer cell-type-specific induction of drug transporters.

The Mediating Effect of Humor on the Relationship between Perceived Stress and Depression in College Students / 한국간호교육학회지

PURPOSE: This study examines the relationships among perceived stress, humor style, responding humor and depression among college students and the mediating effect of humor between perceived stress and depression. METHOD: During the period May 6-16, 2013, a convenience sample of 200 subjects was obtained from college K in city G. Data analysis was performed by Pearson's correlation coefficients and regression analysis. RESULTS: The average BDI score was 7.7. There were 40 (20.0%), 16 (8.0%), 8 (4.0%), and 11 (9.0%) students with mild, moderate, and severe depression, respectively. The group with depressive symptoms constituted 3.5% of students. There was a significant positive correlation between negative stress perception and depression. Conversely, there was a significant negative correlation between adaptive humor style and negative stress perception. Ultimately, there were significant negative correlations between positive stress perception, adaptive humor style, maladaptive humor style, responding humor and depression. To test the mediating effect of adaptive humor style in the relationship between negative stress perception and depression, a Sobel test was performed and Z-score of 1.7736 (p=.076) obtained. CONCLUSION: Though the mediating effect of an adaptive humor style on the relationship between perceived stress and depression was not significant, considering the negative correlation with depression, strategies to increase an adaptive humor style and responding humor is recommended to prevent depression in college students.

Factors Affecting on Health Promoting Behaviors among Teachers with Middle-aged Women Experiencing Menopause / 한국직업건강간호학회지

PURPOSE: This study examined the relationships among menopausal symptom, self-efficacy, health promoting behaviors, and investigated factors affecting health promoting behaviors of teachers with middle-aged women experiencing menopause. METHODS: From September to October 2012, a convenience sample of 252 subjects aged 40 to 60 years was recruited from 8 elementary schools, 3 middle schools and 5 high schools. The data analysis was done by ANOVA and stepwise multiple regression. RESULTS: Menopausal symptom of subjects was slightly lower than general middle aged women and the average level of health promoting behaviors was similar to general middle aged women. Health promoting behaviors were differentiated by severity of menopausal symptom, not by menstruation state. Menopausal symptom was negatively related to health promoting behaviors. The most significant factor affecting health promoting behaviors was self efficacy (14.3%). The combination of self efficacy, menopausal symptom, and elementary school teachers accounted for 20.1% of health promoting behavior. CONCLUSION: When developing health promotion program for teachers with middle-aged women, such program should consider self-efficacy, menopausal symptom, and school type.
