Purpose : Recent research on positive psychology capital has been steadily studied in various fields, including economics, pedagogy, and so on, as a variable to see the performance of the organization.
Positive psychology capital is a concept that emerged from the expansion of economic capital, human capital, and social capital, which are the capital areas of the past, and the positive psychology of individuals can guarantee higher effects than traditional capital, and is drawing attention as studies that can be changed by learning or training are presented.
Therefore, in this study, it was attempted to verify the mediated effects of the role conflict of clinical nurses within the nursing organization between the positive psychological capital and the organizational effectiveness, the effect of nursing performance, and the positive psychological capital on the nursing performance, and the role conflict and organizational effectiveness and the nursing performance.
Method : In this study, the variables used based on the literature review consisted of seven sub-factors of role conflict as independent variables, three sub-factors of organizational effectiveness as subordinate variables, five sub-factors of nursing performance, and four sub-factors of positive psychological capital with parameters.
The reliability of the measurement tools was used through the Cronbach''s alpha coefficient and Confirmatory factor analysis: CFA, and data were collected from September 19 to October 2, 2018 for nurses working at four general hospitals in Ulsan Metropolitan City. Of the total 487, 477 copies, excluding insufficient data, were provided descriptive statistics through IBM''s SPSS statistics 21 and causality and pathways were verified using AMOS version 21.
Results : In this study, the results of the suitability verification of the hypothetical model are as follows:
First, in the hypothetical model, six of the seven hypotheses were adopted and one was rejected.
Second, the positive factor analysis of the hypothetical model shows that the goodness-of-fit index χ2 is 391.889(df=98, p<.001), CFI=.919, TLI=.901, RMSEA=.079 has been validated as a good fit model.
Third, as a result of analyzing the mediated effects of positive psychological capital of nurses between role conflict and organizational effectiveness of nurses and the nursing performance, the direct effect of role conflict of nurses on organizational effectiveness is -.375(p<.001) and the indirect effect of the role conflict of nurses on organizational effectiveness through positive psychological scripts is .623(p<.001) has been shown to have a significant effect, indicating that positive psychology capital acts as a partial mediated in the effect of role conflicts on organizational effectiveness. In addition, the direct effect of role conflict on nursing work was .036(p<.386), and the indirect effect of role conflict on nursing work performance through positive psychological script was .815(p<.001), indicating that positive psychological capital acts as a complete medium in the impact of role conflict on nursing performance.
The analysis results of this study are summarized as follows. The results of the significance verification of the path coefficient showed that the direct path from role conflict to positive psychological capital and organizational effectiveness was significant, while the direct path from role conflict to nursing work showed negative significant impact. In addition, the direct route from positive psychology capital to organizational effectiveness and nursing performance was significant in positive.
Conclusion : In conclusion, this study confirmed that the role conflict of clinical nurses, organizational effectiveness, and nursing performance of nurses not only directly exert influence on organizational effectiveness and nursing performance, but also ultimately affect organizational effectiveness and nursing performance by improving nurses'' positive psychological capital.
Therefore, based on these results, in order to reduce the role conflict of clinical nurses and to improve organizational effectiveness and nursing performance, it is necessary to consider these relevant factors and seek alternatives to various approaches such as environment creation, systematic programs, and counseling processes to increase positive psychological capital.
