The values and work achievement respectively played a mediating role between positive emotions and job engagement,and the two exhibited a chain like mediating effect,with the mediating effect accounting for 28.93% of the total effect. Conclusion There is a chain mediated effect between the core professional nursing values scale and work achievement on the positive emotions and work engagement of junior nurses. Nursing managers should pay attention to cultivating positive emotions and values among junior nurses,enhancing their work achievement,and ultimately promoting their work engagement.更多还原
