Indirect effects were found in the order of hardiness, social support, and distress perception. Self-disclosure showed both direct and indirect effects. CONCLUSION A strategy to improve deliberate rumination is necessary when seeking to improve posttraumatic growth among psychiatric nurses. Enhancing psychiatric nurses' hardiness before trauma would enable them to actively express negative emotions after trauma, allowing them to receive more social support. This would improve deliberate rumination and consequently help promote psychological growth among psychiatric nurses who have experienced trauma. © 2020 Korean Society of Nursing Science.PURPOSE The purpose of this study was to develop a suicide prevention nursing competency program for visiting nurses, and to examine the effect of this program on suicide prevention-related knowledge, attitudes, and behaviors. METHODS A total of 66 visiting nurses were recruited from 10 public health centers and divided equally into the experimental and control group. For the experimental group, the suicide prevention nursing competency program was provided twice a week for 120 minutes across 3 weeks. Participants were asked questions related to suicide prevention knowledge, attitudes, and behaviors at pre, post, and 1 month after the intervention. Data were analyzed using descriptive statistics, a t-test, repeated measure ANOVA, and Friedman test. RESULTS There were significant differences in knowledge and behaviors at the measured time periods, and significant differences in attitudes and behaviors between the two groups. There were also significant interactions between groups and times in attitudes and behaviors. These results suggest that the effects of the program were persistent until the 1-month follow-up. CONCLUSION The developed suicide prevention nursing competency program is effective in evidence-based education for visiting nurses to increase suicide prevention-related knowledge, attitudes, and behaviors. © 2020 Korean Society of Nursing Science.PURPOSE The purpose of this study was to construct and test a structural equation model on nursing work outcomes based on Youssef and Luthans' positive psychological capital and integrated conceptual framework of work performance. METHODS This study used a structured questionnaire administered to 340 nurses. Data were analyzed using structural equation modeling. RESULTS Positive psychological capital showed indirect and direct effects on job satisfaction, retention intention, organizational citizenship behavior, and nursing performance. While, the nursing work environment had direct and indirect effects on job satisfaction and nursing performance, it only had indirect effects on intention to work and organizational citizenship behavior. Additionally, a mediating effect on retention intention and organizational citizenship behavior was found between job satisfaction and nursing performance variables. CONCLUSION The nursing organization needs to build a supportive work environment and reinforce positive psychological capital to improve nursing performance. Additionally, it needs to actively manage the necessary parameters involved in the stages of job satisfaction, retention intention, nursing performance, and organizational citizenship behavior of nurses. The findings propose the continuous management of nursing personnel based on nurses' attitude outcome, behavioral intention, behavioral outcome, and stage of role performance. © 2020 Korean Society of Nursing Science.INTRODUCTION Dementia cafés have recently been attracting attention. The increased involvement of citizen volunteers and the competence of dementia café staff could enhance the potential of dementia cafés. The aim of the present study was to examine enhancement of the competence of citizen volunteers using a new assessment tool. METHODS This cross-sectional analysis included 433 dementia café staff members, including medical and care professionals and citizen volunteers. A 20-item dementia café staff self-assessment (DCSA) instrument was newly developed. After confirmation of the reliability and validity of the instrument, DCSA scores among citizen volunteers were evaluated. RESULTS DCSA showed very good psychometric properties. The mean (±SD) DCSA score was significantly higher for café staff with a medical and care professional background (n = 267) than for citizen volunteers (n = 166) (2.2±0.5 vs. 1.7±0.7, respectively; p less then 0.001).  https://www.selleckchem.com/products/GDC-0980-RG7422.html  The DCSA scores of citizen volunteers became significantly higher with increasing attendance (minimum n = 24; 1.3±0.7; intermediate n = 65; 1.6±0.6; and frequent n = 77; 1.8±0.7; p less then 0.01). CONCLUSION Assessment of the competence of dementia café staff using the DCSA revealed the potential of citizen volunteers. This tool could also enhance the potential of dementia cafés. © 2020 S.

METHODS In this retrospective cohort study of 7,752 men and 6,722 women, we divided the subjects into 4 groups according to sleep duration, i.e., those whose reported regular sleep duration was 6 but less then 7 h (the "6 to less then 7 h group"), those with a sleep duration of 7 to less then 8 h (the "7 to less then 8 h group"), and those with ≥8 h sleep (the "≥8 h group"). CKD was defined as the presence of proteinuria and/or an estimated glomerular filtration rate (eGFR) less then 60 mL/min/1.73 m2. The HR of the 4 groups for incident CKD were calculated with a Cox proportional hazards model, with the 7 to less then 8 h group set as the reference. RESULTS Incident CKD was detected in 1,513 (19.5%) men and 688 (10.2%) women over the median follow-up period of 7.0 (3.3-11.9) years in the men and 6.7 (3.1-10.8) years in the women. There was no association between sleep duration and incident CKD in the women. In the men, the HR of incident CKD was 0.54 (95% CI 0.45-0.64, p less then 0.001) in the less then 6 h group, 0.73 (95% CI 0.66-0.82, p less then 0.001) in the 6 to less then 7 h group, and 0.93 (95% CI 0.78-1.11, p = 0.433) in the ≥8 h group. CONCLUSION The risk of incident CKD is lowest in those who sleep less then 6 h. We revealed that the risk of incident CKD is lowest in those who sleep less then 6 h among apparently healthy men. © 2020 The Author(s) Published by S. Karger AG, Basel.
