The reliability and validity research of the children's revised impact of event scale of Chinese edition / 中华行为医学与脑科学杂志

ABSTRACT

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.
