公众应急准备现状评价量表在北京市小学生人群中的适用性研究

目的在北京市小学生人群中对《公众应急准备现状评价量表》的信度效度进行检验。方法采用多阶段随机整群抽样的方法,在朝阳区、海淀区、大兴区、延庆区选取高年级小学生,使用《公众应急准备现状评价量表》进行问卷调查,使用一致性检验、因子分析等方法对量表信度、效度进行检验。结果有效调查2376人,男生1259人(52.99%),女生1117人(47.01%);量表一致性Cronbach'sα系数为0.79,Spearman-Brown系数为0.53,Gutt?man系数为0.53,按年龄、性别特征分层后,均达到问卷统计学的稳定性要求,去除条目后Cronbach'sα系数均无明显变化;因子分析结果显示量表由4个因子构成,累计方差贡献率解释为58.62%。结论量表可以应用于高年级小学生,但部分条目表述需要进行调整。

Applicability of public emergency preparedness assessment scale on primary school students in Beijing

Objective To test the reliability and validity of the public emergency preparedness assessment scale on primary school students in Beijing.Methods Used multi-stage random cluster sampling method to select senior primary school student samples in Chaoyang District,Haidian District,Daxing District and Yanqing District.Conducted questionnaire survey using the public emergency preparedness evaluation scale.The reliability and validity of the scale were tested by consistency test and factor analysis.Results A total number of 2376 students were surveyed,including 1259 boys(52.99%)and 1117 girls(47.01%);the index of scale consistency,Cronbach'sαcoefficient,was 0.79,the Spearman Brown coefficient was 0.53,and the Guttman coefficient was 0.53.After the sample was stratified by age and gender,the consistency coefficient and half score coefficient of the scale both fall into acceptable range.After removing the items,no significant change in Cronbach'sαcoefficient was observed;Factor analysis showed that the scale was composed of four factors,and the cumulative variance contribution rate was 58.62%.Conclusion The scale can be applied to senior pupils,but some items needs adjustments.
