Most of the autistic disorder patients are also mentally retarded and many mentally retarded persons exhibit autistic symptoms. By using a standard instrument (Ritvo-Freeman Real Life Rating Scale) the autistic features of the mentally retarded children were studied. The study also examined the influence of age, sex and level of mental retardation on the occurrence of autistic symptoms. Children who came for consultation to child psychiatric unit were compared with those at a school for children with mental retardation receiving stimulation. Male children from child psychiatric unit had significantly higher scores than those from the school. Social and language impairment could be reliably identified and grouped. It was possible to diagnose the syndrome of autism in children with mental retardation in a significant number (9.6%)as compared to that was possible only clinically (1.9%). More number of children with severe/ profound mental retardation could be diagnosed as autistic. The autistic syndrome in children with mental retardation can be picked up more effectively by the use of structured instrument.
大多数孤独症患者同时存在智力迟钝，许多智力迟钝患者表现出孤独症症状。本研究使用标准工具（Ritvo-Freeman 现实生活评定量表）对智力迟钝儿童的孤独症特征进行了研究。该研究还检查了年龄、性别和智力迟钝程度对孤独症症状发生的影响。到儿童精神科就诊的儿童与在智障儿童学校接受刺激的儿童进行了比较。儿童精神科的男童比学校的男童得分显著更高。社交和语言障碍可以可靠地识别和分组。与仅通过临床诊断（1.9%）相比，通过使用结构化工具可以对智障儿童中孤独症综合征进行更有效的诊断（9.6%）。更多严重/深度智力迟钝的儿童可以被诊断为孤独症。使用结构化工具可以更有效地发现智障儿童的孤独症综合征。
