目的探讨孤独症幼儿在发育诊断测验过程中的行为特点,以及婴幼儿测试行为量表(ITBRS)在孤独症的临床诊断中的价值。方法研究对象为70例18～42个月的孤独症幼儿以及140名18～42个月的正常幼儿。研究工具为贝利婴幼儿发展量表(BSID)、0～4岁小儿发育诊断量表和ITBRS。结果正常幼儿与孤独症幼儿在ITBRS的任务操作/目标定向、情绪调节、反应性和运动质量等4个因子上的得分以及量表总分上均存在显著性差异(P<0.01),表现为正常组得分明显高于孤独症组的得分。两组之间各条目得分比较显示,只有反应强度在两组间无统计学意义的差异外(P>0.05),其余条目都存在差异(P<0.01或0.05)。孤独症组儿童量表总分100%处于异常测试行为范围。结论孤独症婴幼儿存在明显的测试行为异常。在使用ITBRS评估婴幼儿存在明显测试行为异常时,高度提示他们患有孤独症的可能性。
Objective To investigate the behavioral characteristics of children with autism during developmental diagnostic tests and the value of the Infantile Test Behavior Scale (ITBRS) in the clinical diagnosis of autism. Methods The subjects were 70 children aged 18-42 months with autism and 140 normal children aged 18-42 months. The research tools were the Bailey Infant Development Scale (BSID), Pediatric Developmental Diagnostic Scale 0-4 and ITBRS. Results There was a significant difference (P <0.01) between the score of the four factors of task operation / goal orientation, emotion regulation, reactivity and exercise quality in normal children and autistic children (P <0.01) The score of normal group was significantly higher than that of autism group. The scores of each item between the two groups showed that there was a difference (P <0.01 or 0.05) only if the response intensity was not statistically different between the two groups (P> 0.05). 100% of children with autism spectrum scores in the range of abnormal test behavior. Conclusion Autism infants and young children have obvious test behavior abnormalities. When using the ITBRS to assess infants and toddlers with significant behavioral abnormalities in testing, they are highly suggestive of the possibility of having autism.
