Objectives: Knowledge, barriers/facilitators for pressure ulcer prevention nursing are correlated with attitude and performance of staff nurses. It can be helpful to utilize barriers and facilitators for enhancing the attitude and performance of nurses, there is a gap in the empirical study. The aim of this study was to investigate the relationship between knowledge-barriers/facilitators for Pressure Ulcer (PU) prevention variable set and attitude-nursing performance variable set. Methods: This study employed a cross-sectional descriptive design using structured survey in 9 hospitals. Data were collected from August to November 2018 and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and Canonical correlation. Results: The correct answer rates of knowledge for PU risk factor was 75%. Perceived barriers of prevention was 5.03 ± 1.40 and facilitators was 5.87 ± 1.28. The mean score of attitude for PU prevention was 3.53 ± 0.30 and that of nursing performance for PU prevention was 1.42 ± 0.33. The significant pair of canonical variate indicated that more perceived barriers (0.75), less facilitators (-0.51), low knowledge level for risk factor of pressure ulcer (-0.31), and high knowledge level for pressure ulcer prevention (0.59) were associated with poor nursing performance for pressure ulcer prevention (-0.96). Conclusions: To enhance the nursing performance for PU prevention, developing nurse-centered educational program and standardized protocol should be needed. Also, planning sheet for PU prevention can increase the nursing performance.

Test anxiety and self-efficacy significantly influence the mastery of nursing skills. Facial expression recognition tools are central components to recognising these elements. This study investigated the frequent facial expressions conveyed by nursing students and examined the relationships between nursing skill mastery, test anxiety, self-efficacy, and facial expressions in a test-taking situation. Thirty-three second-year nursing students who were attending a university in a Korean metropolitan city participated. Test anxiety, self-efficacy, and facial expressions were collected while the students inserted indwelling catheters. Using Microsoft Azure software, the researchers examined the students’ facial expressions. Negative facial expressions, such as anger, disgust, sadness, and surprise, were more common during the test-taking situation than the practice trial. Fear was positively correlated with anxiety. None of the facial expressions had significant relationships with self-efficacy; however, disgust was positively associated with nursing skill mastery. The facial expressions during the practice and test-taking situations were similar; however, fear and disgust may have been indicators of test anxiety and skill mastery. To create a screening tool for detecting and caring for students’ emotions, further studies should explore students’ facial expressions that were not evaluated in this study.

The objectives of this study were to elucidate the relationship between geriatric care hospital nurses' professional self-concept, self-leadership, and their geriatric nursing performance and to clarify factors that affect geriatric nursing performance. Methods: A questionnaire-based survey was conducted among 159 individuals working at 12 geriatric hospitals. To evaluate professional self-concept, Nurses' Self-Concept Instrument (NSCI) developed by Angel et al. were used. And, The data were collected from December 29, 2015 to January 30, 2016, and analyzed with descriptive statistics, t-test, and ANOVA, multiple regression conducted using SPSS 18.0. Scheffé test was utilized for post hoc tests. Results: The average score of professional self-concept was 6.02 ± 0.84 out of 8 points, that of self-leadership was 3.69 ± 0.44 out of 5 points, and that of geriatric nursing performance was 3.79 ± 0.52 out of 5 points. Four subcategories of professional self-concept showed significant positive correlations with nine subcategories of geriatric nursing performance, with correlations ranging between 0.18 and 0.57. 'Knowledge' subcategory of professional self-concept was the factor that would affect geriatric sleep quality care nursing most significantly (t = 2.83, p = 0.005), and that it additionally explained 30% of sleep quality care nursing performance after controlling for general characteristics. As for communication in nursing, 'staff relation' of professional self-concept (t = 2.21, p = 0.029) and 'rehearsal' subcategory of self-leadership (t = 2.24, p = 0.027) were significant factor, and 26% explaining change of communication in nursing. Conclusions: Influencing factors of geriatric nursing performance were participants' socio-demographic characteristics such as monthly income and number of beds, and the subcategories of professional self-concept and self-leadership. Based on the results of this study, interventions to improve nurses' professional self-concept and self-leadership should be needed for enhancing nursing performance in geriatric hospitals.

Metabolic syndrome (MetS) and severity of coronary artery disease (CAD) are considered predictors of CAD prognosis. Unhealthy lifestyles and type-D personality are associated with MetS and are potential causes of primary and secondary CAD. In this cross-sectional descriptive study, we aimed to investigate the relationship between behavioral-psychological variables and predictors of CAD prognosis. The behavioral-psychological variable set contained six lifestyle categories and two type-D personality categories. Descriptive analyses, t-tests, analysis of variance, Pearson’s correlation, and canonical correlation were used. The behavioral-psychological variable set was related to the predictor set for CAD prognosis, with a significant canonical variate of 0.67 (45% overlapping variance). Significant pairs of canonical variates indicated that poor physical activity and weight control (−0.77), poor dietary habits (−0.78), alcohol consumption and cigarette smoking (−0.37), lack of sleep and rest (−0.40), stress (−0.64) in the lifestyle set, higher negative affectivity (0.52), and social inhibition (0.71) in the type-D personality set were associated with a high MetS score (0.59) and severity of CAD (0.91). A combination of behavioral and psychological variables was found to be important in predicting the prognosis of CAD; therefore, interventions aimed at preventing combinations of these variables may be effective in improving CAD prognosis.

Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean Version of the Nurses' Self-Concept Instrument (NSCI) geriatric hospital nurses in Korea. Methods: Bilingual nursing professionals performed translation and back-translation. Reliability and validity of the content and construction of the instrument were confirmed. Internal consistency reliability was determined. Construction and concurrent validity were verified using factor analysis and correlation coefficients. Results: The total 14 items for the Korean version of the Nurses' Self-Concept Instrument (NSCI) were retained through item analysis. In explanatory factor analysis, four subcategories were proposed with their names of each factor: 'Leadership', 'Staff relation', 'Knowledge', and 'Care'. The four factors accounted for 78.81% of the variances. The Cronbach's ⍺ regarding internal consistency were .77~.91 for the NSCI subscales. Correlation among four subcategories ranged .62~.84. Conclusion: The findings show that the Korean version of the Nurses' Self-Concept Instrument is reliable and valid for measuring professional Self-Concept of geriatric hospital nurses in Korea.
