摘　　要：目的:通过建立护理工作中非注意盲视影响因素预测模型,分析知觉负荷、注意定势、消极情绪与护理非注意盲视之间的关系。方法:2020年6月—7月,采用便利抽样法选取贵阳市3所三级综合医院的976名护士为研究对象,对其护理非注意盲视的影响因素进行问卷调查,采用结构方程模型分析护士知觉负荷、注意定势和消极情绪在非注意盲视出现过程中的作用和机制。结果:注意定势、知觉负荷、消极情绪正向影响非注意盲视,其解释率为70.2%。知觉负荷对非注意盲视的总效应为0.435,直接效应为0.196,消极情绪在此路径中的中介效应为0.239,中介效应占比为54.9%;注意定势对非注意盲视的总效应为0.434,直接效应为0.234,消极情绪在此路径中的中介效应为0.200,中介效应占比为46.1%。结论:知觉负荷、注意定势、消极情绪是护理非注意盲视的直接影响因素,同时,消极情绪在知觉负荷、注意定势与护理非注意盲视之间起到中介效应,且呈正向预测作用,本研究结果可为今后有针对性地预防护理非注意盲视的发生提供理论依据。Objective:To analyze the relationship between perceptual load,attentional set,negative emotion and nursing Inattentional Blindness(IB)by establishing a predictive model of the influencing factors of IB in nursing.Methods:From June to July 2020,976 nurses from three tertiary general hospitals in Guiyang were selected by convenience sampling method.The status and the influencing factors of nurses’IB were investigated.The structural equation model was used to analyze the roles of nurses’perceptual load,attentional set and negative emotions in the emerging of nursing IB.Results:Attentional set,perceptual load,and negative emotions positively affected IB,with an interpretation rate of 70.2%.The total effect of perceptual load on IB was 0.435,the direct effect was 0.196,and mediation effect was 0.239,accounting for 54.9%.The total effect of attentional set on IB was 0.434,direct effect was 0.234,and mediation effect was 0.200,accounting for 46.1%.Conclusion:Perceptual load,attentional set and negative emotions are the direct influencing factors of nursing IB,while negative emotions play an intermediary effect between perceptual load,attentional set and the occurrence of IB in nursing,and have a positive correlation predictive effect.The results of this study provide a theoretical basis for the targeted prevention of the occurrence of nursing IB in the future.
