【摘要】 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。更多还原

【Abstract】 To explore the structure of the risk perception of urban inhabitants,we developed a survey questionnaire of risk perception including 23 items.Exploratory Factor Analysis(EFA) shows that their risk perception contains five factors:controllability,visibility,fearfulness,possibility and severity of risk,which can explain 54.775% of the whole variance.Reliability tests show that the a coefficient is from 0.5799 to 0.8527 and the split-half reliability is from 0.5352 to 0.8420,the correlation coefficient between factors and summation is higher than that between factors,all with statistical prominence.The reliability and validity of the questionnaire are excellent.The Confirmatory Factor Analysis(CFA) of data from another sample confirmed the factor validity of this questionnaire.更多还原
