【摘要】 目的：评价从美国引进的LITE-S问卷和CROPS量表，初步判断其是否宜在本土应用。方法：以整群抽样方法抽取8-18岁广州市区普通中小学校学生以及市内两所特殊学校学生(聋人学校与工读学校)为调查对象。量表经翻译-回译程序，以青少年行为自评量表(Achenbach YSR-1991)为效标。采用评价指标有Cronbachα系数、重测信度系数、内容效度、结构效度、判别效度、效标效度等。结果：创伤事件终身经历问卷-学生版(LITE-S)Cronbachα系数为0.794，5周重测信度系数为0.760；创伤后症状自评量表(CROPS)Cronbachα系数为0.903，5周重测信度系数0.765。创伤事件终身经历总数是CROPS量表得分总变异的一个归因因素。因子分析把CROPS量表分为五因子：回避和抑郁因子，闪入思想和高警觉因子，躯体症状因子，自伤感和罪恶感因子，睡眠障碍因子；其中自伤感和罪恶感因子能区分特校学生与普校学生；特校组学生在CROPS量表症状总均分比普校学生高且有统计学意义；心理问题检出组(以YSR为标准)在CROPS量表总分均数比非检出组高且有统计学意义。CROPS量表PTSD症状总得分与YSR的各个综合征的平均相关系数为0.6332±0.1129，各系数均有统计学意义。结论：1 LITE-S问卷和CROPS量表符合心理测量学信度与效度的基本要求。2可以引入LITE-S问卷和CROPS量表用于8-18岁儿童青少年团体测量与比较。更多还原

【Abstract】 Object: Validating Chinese Version of the Life Incidence of Traumatic Event-Student form and Child-report Posttraumatic Symptom introduced from USA, in order to evaluating its utility locally.Method: The cluster sampling method was employed to recruit the 8-18 pupils and students in the normal community schools and two special school, one school for the deaf-mutes and the other one for borderline delinquency male student. Achenbach’s YSR was chosen to serve as the validity criteria. The translation and back translation procedure was undertaken according to the author’s recommendation. Several psychometrical indicators were analyzed for reliability and validity about the Chinese version of LITE-S and CROPS, such as Cronbach’s alpha coefficient, test-retest coefficient, content validity, construct validity, discriminate validity, criteria validity.Result: The Cronbach’s alpha coefficient for LITE-S and CROPS was 0.794 and 0.903 respectively. The five-week test-retest coefficient for LITE-S and CROPS was 0.760 and 0.903, respectively. The total number of lifetime incidence traumatic events accounted for a contributor of total score on CROPS. There five factors were produced through the factor analysis with oblique rotation. The first factor was avoidance and depression, the second was intrusion and high arousal, the third one was somatic complaint, the forth was sense of guilty and sadness, the fifth was sleeping disorder. Among these five factors, the forth factor discriminated between the students from normal schools and special schools. Higher total mean score on CROPS was found among the students from special schools than that of the students from normal schools significantly. The students having behavior problems screened by YSR were higher in total mean score on CROPS than those of the students without having behavior problems statistically. The average coefficient between the total score on CROPS and the eight symptoms defined by YSR was 0.6332±0.1129. All the coefficients were significant statistically.Conclusion:1 The Chinese version of LITE-S and CROPS which are the screening tools of traumatic events and posttraumatic symptom for children and adolescents introduced from USA meet the important psychometrical requirements.2 LITE-S and CROPS can serve as the candidate for screening traumatic events and posttraumatic symptom in groups of children and adolescents aged 8-18 for the purpose of measuring and comparing within groups.更多还原
