新型冠状病毒肺炎城市公众防护行为决策模型的初步构建

Construction of public protective action decision model in a city with COVID-19

目的从风险感知、防护认知以及权威信任的视角探讨影响公众防护行为的关键环节,构建新型冠状病毒肺炎城市公众防护行为决策模型。方法采用便利抽样的方法于2020年2月2日—2020年2月6日采用“问卷星”电子问卷收集系统对1201名公众进行横断面资料收集。调查工具包括一般资料调查表、新型冠状病毒公众防护行为决策量表。使用SPSS 22.0统计学软件对数据进行统计,使用AMOS 23.0对风险感知、防护认知、权威信任度以及防护行为4个变量之间的关系进行探索,构建新型冠状病毒公众防护行为决策模型。结果构建的结构方程模型适配度好,风险感知对防护行为的直接效应为0.410,防护认知对防护行为的直接效应为0.070,权威信任度对防护行为的总效应为0.377。结论我国公众防护行为依从性好,该模型可有效预测城市公众新型冠状病毒肺炎防护行为。

Objective To explore the key influencing factors of public protective action from the angle of risk perception,protective cognition and authority trust so as to build the public protective action decision model in city with COVID-19.Methods From 2ed February,2020 to 6th February,2020,we carried out cross-sectional investigation among 1201 publics selected by convenience sampling with the"Wen Juan Xing"electronic questionnaire collection system.The investigation tool included the general information questionnaire and the COVID-19 public protective decision-making scale.SPSS 22.0 was used to data statistics and AMOS 23.0 was applied to explore correlations among four variables,risk perception,protective cognition,authority trust and protective action,so as to build the COVID-19 public protective action decision model.Results The structural equation model had a high level of goodness-of-fit,the direct effect of risk perception on protective action was 0.410;the direct effect of protective cognition on protective action was 0.070;the total effect of authority trust on protective action was 0.377.Conclusions In China,the public have good compliance of protective action.The model can effectively forecast the protective action of COVID-19 among city publics.
