摘要目的:探讨焦虑和心流在护理专科生压力知觉和手机成瘾间的链式中介作用。方法:2021年12月，采用中文版压力知觉量表、GAD-7焦虑症筛查量表、心流量表和大学生手机成瘾倾向量表对黑龙江省某护理专科院校4 179名大一、大二学生进行横断面调查，回收有效问卷3 050份，用SPSS 26.0统计软件进行共同方法偏差检验、描述统计、相关分析，采用AMOS 24.0进行中介效应检验。结果:(1)3 050名学生中，手机成瘾者为714人(23.41%)。(2)压力知觉[(27.31±9.56)分]与焦虑[7.00(1.00，10.00)分]、心流体验[(12.00±3.40)分]、手机成瘾[(42.42±13.05)分]均呈正相关( r＝0.441，0.517，0.476，均 P<0.05)；焦虑与心流体验、手机成瘾呈正相关( r＝0.430，0.538，均 P<0.05)；心流体验与手机成瘾呈正相关( r＝0.490， P<0.01)。(3)焦虑、心流体验在压力知觉和手机成瘾间起单独的中介和链式中介作用，效应值分别占总效应的26.06%(0.165/0.633)、23.54%(0.149/0.633)和3.48%(0.022/0.633)。 结论:压力知觉不仅能直接影响护理专科生手机成瘾，而且通过焦虑和心流体验的独立中介作用和链式中介效应间接影响护理专科生手机成瘾。

abstractsObjective:To explore the chain mediating effect of anxiety and flow experience on perceived stress and mobile phone addiction in nursing college students.Methods:In December 2021, a cross-sectional design survey was conducted on 4 179 freshmen and sophomores in a nursing college in Heilongjiang Province. The Chinese perceived stress scale, generalized anxiety disorder-7, flow state scale, and mobile phone addiction tendency scale were selected separately to assess perceived stress, anxiety symptoms, flow experience and mobile phone addiction. SPSS 26.0 software was used for descriptive analysis, independent sample t-test, Spearman correlation analysis, and AMOS 24.0 software was used for mediating effect test. Results:(1) Among the 3 050 nursing students, there were 714(23.41%) students who were addicted to mobile phones. (2) Spearman correlation analysis indicated that perceived stress(27.31±9.56) was positively correlated with anxiety(7.00(1.00, 10.00), r=0.441, P<0.05), flow experience((12.00±3.40), r=0.517, P<0.05), and mobile phone addiction((42.42±13.05), r=0.476, P<0.05).Anxiety was positively correlated with flow experience ( r=0.430, P<0.01) and mobile phone addiction ( r=0.538, P<0.01).Flow experience was positively correlated with mobile phone addiction ( r=0.490, P<0.01). (3) Anxiety and flow experience played seperate mediating and chain mediating roles between perceived stress and mobile phone addiction, accounting for 26.06%(0.165/0.633), 23.54%(0.149/0.633) and 3.48%(0.022/0.633) of the total effect. Conclusion:Perceived stress not only directly affects the mobile phone addiction of nursing students, but also indirectly affects mobile phone addiction through the independent and chain mediating effects of anxiety and flow experience.
