尝试探索城市居民风险认知的结构。在深度访谈和文献整理的基础上,研究形成了23个项目的城市居民风险认知调查问卷。探索性因素分析表明城市居民的风险认知结构由5个因子构成,分别是:风险的可控性,风险的可见性,风险的可怕性,风险的可能性和风险的严重性,五个因子共解释了风险认知总变异的54.775%。信效度检验表明,各因子与总分的α系数在0.5799-0.8527之间,分半信度在0.5352-0.8420之间,各因子与总分的相关高于各因子间的相关,都达到了统计学的显著性,同时验证性因素分析也证实了该问卷的构想效度。
Try to explore the structure of urban residents’ risk perception. Based on in-depth interviews and literature review, a questionnaire on risk perception of urban residents with 23 projects was developed. Exploratory factor analysis shows that the risk perception structure of urban residents is composed of five factors: controllability of the risk, visibility of the risk, the scary risk, the possibility of the risk and the severity of the risk. Five factors A total of 54.775% of the total variance in risk perception was explained. The test of reliability and validity shows that the α coefficient of each factor and the total score is between 0.5799 and 0.8527 and the half reliability is between 0.5352 and 0.8420. The correlation between each factor and the total score is higher than the correlation between each factor, Statistical significance, and confirmatory factor analysis also confirmed the validity of the questionnaire.
