中文版儿童事件影响量表的信效度研究

目的 对中文版儿童事件影响量表(The Children's Revised Impact of Event Scale,CRIES-13)进行信度、效度检验.方法 2008年9月,根据受灾情况在两所中学选择符合人选标准的600名同学为调查对象.中文版儿童事件影响量表的信度用重测信度、克朗巴赫α系数、分半信度进行分析.效度研究用内容效度、效标效度及结构效度分析.结果 在CRIES-13的重测信度检验中,得出Spearman相关系数分别为:总分(0.79),闯入因子(0.75),回避因子(0.71),高觉醒因子(0.75),其相关均有显著性(P<0.01).CRIES-13的总体克朗巴赫α系数为0.81;3个因子的克朗巴赫仅系数分别为:闯入因子(0.79),回避因子(0.71),高觉醒因子(0.65).CRIES-13的分半信度为0.85.在内容效度检验中,各项目得分与总分间的Spearman等级相关系数分别为闯入因子(r=0.83)、回避因子(r=0.75)、高觉醒因子(r=0.85).各因子之间的相关系数在闯入因子-回避因子(r=0.63)、回避因子-高觉醒因子(r=0.41)、闯入因子-高觉醒因子(r=0.41)(均P<0.01).在结构效度中,采用方差最大正交旋转法因子分析归纳为3个公共因子,其对总方差的累积贡献率为55.52%.在效标效度检验中,CRIES-13的闯入、高觉醒因子分别与SDQ的情绪因子、DSRSC总分具有显著的相关性,且有统计学意义.结论 CRIES-13量表对于汶川地震幸存儿童PTSD症状的筛查具有较好的信度、效度,值得在灾后推广使用.

The reliability and validity research of the children's revised impact of event scale of Chinese edition

Objective To test the reliability and validity of CRIES-13(Chinese edition). The Children Revised Impact of Event Scale (CRIES-13) was recommened for diagnosing PTSD of children. Methods In the last third of the September 2008,according to the suffering condition,600 students were choosed who were fit for the research standard as subjects in two middle schools randomly. The viability of CRIES-13 was weighted by testretest reliability,Cronbach' s alpha,Split half reliability. The validity of CRIES-13 was analysed by content validity ,criterion validity,construction validity. Results In the test-retest reliability of CRIES-13, the Spearman correlation coefficient of total,intrusion factor,avoid factor,high warkening factor were 0.79, 0.75, 0.71, 0.75. Significant correlation were found among these scores. The Cronbach' s alpha of population was 0. 81. The Cronbach' s alpha of three factors was 0. 79 ( intrusion factor) , 0. 71 ( avoid factor), 0. 65 ( high awarkening factor). CRIES-13's split-half reliability was 0. 85. In the content validity test,the Spearman rank correlation coefficient between total score and each item was 0. 83 (intrusion factor), 0. 75 (avoid factor), 0. 85 (high awarkening factor). The correlation between intrusion factor and avoid factor was 0.63. The correlation between avoid factor and high awarkening factor was 0.41. The correlation between intrusion factor and high awarkening factor was 0.41. In struction validity, variance orthogonal rotation factor analysis was adopted and got three general factors. Their cumulative contribution to total variance was 55.52%. In the criterion validity test,significant correlation was found between intrusion factor and SDQ emotional factor and depression scale total score. Significant correlation was found between high awakening factor and SDQ emotional factor and depression scale total score. Conclusion The reliability and validity of CRIES-13 was good. It could be used extensively.
