ABSTRACT
Objective:To explore the role of multiple mediating effects on scientific research creativity of nursing postgraduates.Methods:In the study, 127 nursing postgraduates from three affliated hospitals of Chongqing Medical University were selected by convenience sampling. The investigation scale included general information questionnaire, tutor support scale, nursing scientific research self-efficacy scale, autonomy motivation scale and scientific research creativity scale. The questionnaire of nursing postgraduates was collected through the Sojump platform, and the data of 127 postgraduates were effectively collected in strict accordance with the inclusion and exclusion criteria. The difference analysis and correlation analysis were carried out by SPSS.Results:The correlation analysis showed that nursing postgraduates' scientific research self-efficacy and autonomy motivation were significantly positively correlated with tutor support and scientific research creativity ( P<0.05). Multiple linear hierarchical regression analysis showed that nursing research self-efficacy and autonomy motivation played a partial mediating role between tutor support and scientific research creativity ( P<0.05), in which the mediating role explained 13.1% and 4.2% of the variation respectively. The structural equation model further verified the role of multiple mediating effects on the scientific research creativity of nursing postgraduates. Conclusion:The scientific research creativity of nursing postgraduates is closely related to tutor support, scientific research self-efficacy and autonomy motivation. Tutors can enhance nursing postgraduates' scientific research self-efficacy and autonomy motivation by improving the level of tutor support, so as to improve the scientific research creativity of postgraduates.
ABSTRACT
Objective To explore the multiple mediating effect of sleep quality and internet addiction between negative life events and mental health among college students.Methods A cross-sectional study was used to investigate 733 college students with adolescent self-rating life events checklist,Pittsburgh sleep quality index,the general health questionnaire and internet addiction scale for Chinese revision.SPSS and Bootstrap method were used to test the hypothetical model.Results The scores of Negative life events,sleep quality,interaet addiction and mental health were 46.0 (33.0,66.5),5.0 (3.0,7.0),44.0 (37.0,50.0) and 5.0(2.0,9.0) respectively,and they were positively correlated with each other (r=0.39-0.55,P＜0.01).Negative life events had a direct effect on mental health.The effect value was 0.013,and the effect size was 17.97％.The simple mediating effects of sleep quality and internet addiction between negative life events and mental health were significant.The effect values were 0.047 and 0.009,and the effect sizes were 64.85％ and 11.94％,respectively.The chain mediating effect of sleep quality-internet addiction was also significant,and the effect value was 0.004 and the effect size was 5.24％.Conclusion Negative life events not only directly affect mental health in college students,but also indirectly affect their mental health through the multiple mediating effects of sleep quality and internet addiction.
