目的 探讨护理实习生临床归属感在学业支持感知和压力间的中介效应。 方法 选取553名正在医院实习的护理专业学生作为研究对象,应用临床归属感量表、护理实习生学业支持感知量表和护理专业学生压力指数量表进行调查。 结果 护理实习生临床归属感条目均分为（3.56±0.49）分,学业支持感知条目均分为（6.61±1.60）分,压力条目均分为（3.74±0.59）分。护理实习生学业支持感知与压力呈负相关（r=-0.801）,与临床归属感呈正相关（r=0.673）,压力与临床归属感呈负相关（r=-0.743）。临床归属感在学业支持感知和压力间的中介效应为-0.088,占总效应的31.3%。结论 护理实习生临床归属感在学业支持感知和压力间起中介作用,可为缓解和减少其压力提供新思路。

Objective To explore the mediating effect of clinical sense of belonging between perception of academic support and stress in nursing interns. Methods A total of 553 nursing interns were recruited and investigated with the Belongingness Scale-Clinical Placement Experience,the Academic Support in the Practicum Scale and the Student Nurse Stress Index Scale. Results The scores of clinical sense of belonging,perception of academic support and stress were（3.56±0.49）,（6.61±1.60） and （3.74±0.59） respectively. There was a negative correlation between perception of academic support and stress（r=-0.801）,and a positive correlation between perception of academic support and clinical sense of belonging（r=0.673）. There was a negative correlation between stress and clinical sense of belonging（r=-0.743）. The mediating effect of clinical sense of belonging between perception of academic support and stress of nursing interns was -0.088,accounting for 31.3% of the total effects. Conclusion Clinical sense of belonging plays a mediating role between perception of academic support and stress in nursing interns,which can provide new ideas for relieving and reducing stress of nursing interns.
