The Influence of Grit on Turnover Intention of University Hospital Nurses: The Mediating Effect of Job Involvement

PURPOSE: This study aimed to confirm the mediating effect of job involvement in the relationship between grit and turnover intention among nurses working at university hospitals. METHODS: Participants included 437 nurses from university hospitals located in C city, Gyeongnam. Data were collected from January 8 to 19, 2018, using self-report questionnaires. Data were analyzed using the t-test, analysis of variance, Scheffe's test, Pearson's correlation coefficient, and multiple regression, with the SPSS/22.0 program. A mediation analysis was performed according to the Baron and Kenny, and bootstrapping methods. RESULTS: There were significant relationships between grit and job involvement (r=.40, p<.001), grit and turnover intention (r=−.29, p<.001), and turnover intention and job involvement (r=−.52, p<.001). Job involvement showed partial mediating effects in the relationship between grit and turnover intention. CONCLUSION: Grit increased job involvement and lowered turnover intention. Therefore, to reduce nurses' turnover intention, it is necessary to develop a program and strategies to increase their grit.

Structural Equation Model for Sleep Quality of Female Shift Work Nurses

PURPOSE: This study aimed to develop and test a structural model for sleep quality in female shift work nurses. The hypothetical model was constructed on the basis of Spielman's 3P model of insomnia and previous research related to the sleep quality of shift nurses. METHODS: This cross-sectional study used structural equation modeling and recruited 285 female shift work nurses from four general and university hospitals with over 300 beds located in C and J cities in Gyeongsangnamdo. Data were collected from September 27 to October 20, 2016, and then analyzed using descriptive statistics, Pearson's correlation, and structural equation modeling. The study used SPSS/Win 18.0 and AMOS 18.0 in processing the data. RESULTS: The final model showed good fit to the empirical data: χ2/df=2.19, SRMR=.07, RMSEA=.07, AGFI=.85, TLI=.91, GFI=.93, GFI=.89, NFI=.87. The factors that influenced sleep quality were sleep hygiene (β=.32), perceived shift work status (β=−.16), stress response (β=.16), shift work experience (β=.15), perceived health status (β=−.14), and circadian rhythm (β=−.13) explaining 36.0% of the variance. CONCLUSION: The model of sleep quality of the shift work nurses constructed in this study is recommended as a model to understand and predict the sleep quality of shift work nurses. The results suggest that strategies for improving the sleep quality of shift work nurses should focus on sleep hygiene, perceived health status, stress response, circadian rhythm, perceived shift work status, and shift work experience.

Two Cases of Free Fat Graft at Patulous Eustachian Tube / 대한이비인후과학회지

Previously the patulous eustachian tube has been regarded as troublesome but benign condition. Recently some cases have been reported in conjunction with middle ear complications. In spite of its intractability, pathophysiology and specific therapy for this condition has not been fully investigated. We experienced two cases of abnormally patulous eustachian tube, the 23-year-old patient who complained autophonia and the 36-year-old female patient who complained autophonia with tinnitus, and they were treated with autologous free fat injection. We report these cases with a brief review of the literatures.
