Factors Related to Positive Psychological Capital among Korean Clinical Nurses: A Systematic Review and Meta-Analysis / 임상간호연구

ABSTRACT

PURPOSE@#The purpose of this study was to systematically review and identify factors relevant to the positive psychological capital of clinical nurses.@*METHODS@#These was no limit on year of publication. Articles related to Korean clinical nurses were retrieved from computerized database using a manual search. A systematic review was conducted based on the PRISMA flow. The total correlational effect size (ESr) for each related factor was calculated from Fisher's Zr. Funnel plots, fail-safe numbers, and Egger regression tests were used to evaluate publication bias in meta-analysis studies. The correlational effect size of 25 studies was analyzed through meta-analysis using Comprehensive Meta-Analysis software 3.0 (CMA).@*RESULTS@#The review included 25 studies. In the systematic review, 14 demographic factors and 46 organizational factors were found to be influential. Eleven factors (6 demographic factors and 5 organizational factors) were appropriate for meta-analysis. The overall effect size was .26. The demographic total correlation effect size of related factors was .20 and the total effect size of organization was .46. Organizational commitment (ESr=.38) and job satisfaction (ESr=.54) were statistically positively related variables. Negative variables were burnout (ESr=−.61), turnover intention (ESr=−.41) and workplace bullying (ESr=−.33). The total effect size of the organizational factors was larger than the demographic total effect size. There was no publication bias except for demographic variables.@*CONCLUSION@#Organizational factors and adjustable variables have a significant impact on positive psychological capital. The results of this study support the need for development of interventions focusing on organizational factors.
