中文版“太田阶段评价法”在儿童自闭症中的应用

Application of Chinese version-Ohta staging evaluation in children with autism

目的：通过对中文版＂太田阶段评价法＂的信度和效度的研究来验证其在儿童自闭症应用中的妥当性。方法：在北京、青岛和大连选取自闭症儿童175例,正常儿童132例,对其进行太田阶段评价和比内智商测试,并由家长填写自制的访谈问卷。结果：①信度分析：全量表和各项目之间的Cronbach’sα系数均大于0.7,重测信度系数为0.985和0.976。②效度分析：太田阶段的总得分与各分项得分的相关系数为0.5480.897,说明其具有良好的内容效度。不同年龄组儿童的太田阶段得分与智商呈强的正相关,系数为0.8280.976;太田阶段和语言能力之间也呈很强的正相关,系数为0.785,效标效度良好。另外,各年龄段对照组的太田得分均显著高于自闭症组,说明其具有良好的区分效度。结论：中文版＂太田阶段评价法＂具有良好的信度和效度,操作简便,结果再现性高,是一种有效地评估自闭症儿童认知能力的工具。

Objective：To verify the value of Chinese version-Ohta staging evaluation in children with autism by investigating the reliability and validity.Methods：175 children with autism and 132 normal children were selected from Beijing,Qingdao and Dalian,then they received Ohta staging evaluation and Binet IQ scale,a self-designed questionnaire was finished by their parents.Results：Reliability analysis： the Chronbach’s α coefficients of whole scale and every item were above 0.7,the coefficients of test-retest were 0.985 and 0.976,respectively.Validity analysis： the correlation coefficient of total score and score of every item was 0.548～0.897,which indicated that Ohta staging evaluation had a good content validity.There was a positive correlation between score of Ohta staging evaluation and IQ in different age groups,the coefficient was 0.8280.976,and there was a positive correlation between Ohta staging evaluation and language ability,the coefficient was 0.785,which showed that Ohta staging evaluation had a good criterion validity.The scores of Ohta staging evaluation at all age groups in control group were significantly higher than those in autism group,which indicated that Ohta staging evaluation had a good differential validity.Conclusion：Chinese version-Ohta staging evaluation has good reliability and validity with high reproducibility and can be operated conveniently,which is an effective method in evaluating cognition of children with autism.
