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。

Behavioral features of children with autism in developmental test

??Objective??To explore behavioral features of children with autism in developmental test. Methods??The subjects were 70 Autistic children ranging from 18 to 42 months in age??31.98±6.38???? and 140 normal children ranging from 18 to 42 months in age??31.39±6.30??. They were assessed by the Bayley Scales of Infant Development ??BSID???? the Developmental Diagnostic Scale of Children Aged 0??4 Years?? and infants and toddler’ behavior rating scale ??ITBRS??. Results??T tests showed that scores of orientation?? emotional regulation?? responsiveness and motor quality ?? and total scores of ITBRS were lower in autistic children than normal children??P < 0.01??. In autistic children group?? scores of orientation?? emotional regulation?? responsiveness and motor quality ?? and total scores of ITBRS were 14.54± 4.60?? 19.36±4.74?? 18.53±3.75?? 9.37±1.22?? 72.01±11.01 respectively. In normal children group?? scores of orientation?? emotional regulation?? responsiveness and motor quality ?? and total scores of ITBRS were 26.78±4.89?? 31.69±4.50?? 21.76±2.14?? 9.86±0.54?? 102.72 ±9.54 respectively. Conclusion??There are differences in tested behaviors between autistic children and normal children. Ability of orientation?? emotional regulation?? responsiveness and motor quality were lower in Autistic children than those in normal children. The results indicated that ITBRS can be used as a Screening tool for autistic disorders.
