暴力恐怖袭击应对行为量表在大学生中应用的信效度评价

Reliability and validity of individual response to terrorism scale among undergraduates

目的评价暴力恐怖袭击应对行为量表应用于大学生群体的信度与效度,为量表在全国的推广使用提供科学依据。方法采用分层整群抽样方法,抽取广州市5所高校在读本科生1 657名,运用暴力恐怖袭击量表进行自我评定,采用同质性信度、分半信度进行信度分析,采用内容效度和结构效度进行效度评价。结果大学生对暴力恐怖袭击应对行为量表总体Cronbachα系数为0.817,量表总体Spearman相关系数为0.745;量表中的个人准备行为、信息寻求行为和规避行为与总量表的Pearson相关系数分别为0.930,0.637,0.691,差异均有统计学意义(P值均<0.01);因子分析结果表明,3个公因子特征值分别为4.316,1.286,1.044,方差贡献率分别为33.20%,9.89%,8.03%,累计方差贡献率为51.12%,分别命名为准备行为、信息寻求行为和规避行为。所有条目的因子载荷均大于0.40。结论暴力恐怖袭击应对行为量表在大学生中应用具有较好的信度与效度,可作为中国大学生对暴力恐怖袭击应对行为情况评价的有效工具。

Objective To evaluate the reliability and validity of individual response to terrorism scale among undergradu- ates, and to provide scientific basis for the use of the scale in China. Methods Totally 1 657 undergraduates from 5 colleges or u- niversities in Guangzhou, using stratified cluster method, were interviewed. The internal consistent reliability, split-half reliability, content validity and construct validity of the scale were examined. Results Of the respondents, 853 （ 51.48% ） were male. The Cronbach coefficient and the Spearman correlation coefficient of the items of the whole scale were 0.817 and 0.745, respectively. The Pearson correlation coefficient between the three subscales and the whole scale ranged from 0.691 to 0.930, with significant sta- tistical differences. Factor analysis indicated that the initial eigenvalues of the three components were 4.316, 1.286 and 1.044, re- spectively. The percentage of variance was 33.20%, 9.89% and 8.03%, respectively. The cumulative percentage of components was 51.12%. The three components were named individual preparedness, information seeking and avoidance, respectively. The factor loadings of all items were over 0.4. Conclusion The individual response to terrorism scale has good reliability and validity among undergraduates and could be used as an effective tool for assessing individual preparedness behaviors of violent terrorist attacks a- mong undergraduates in China.
