Data were collected, using interviews with parents and teachers and rating scales, concerning the behaviour of two groups of mentally retarded children: 193 children with Down's Syndrome (DS) and 154 children with a similar degree of handicap were identified in the same schools. The proportions of children who had high scores on the Rutter or an additional behaviour check list, were similar in the two groups. Deviant behaviour was markedly more common in both sets of retarded children than in their siblings next in age; 31% of the children with DS and 29% of controls were judged to be well adjusted, while 38% of the DS children and 49% of the controls had significant behaviour disorder. Conduct disorders were most common in the children with DS. 'Psychosis' was the most common diagnostic label in the control group, but was also found in the children with DS.
在同一学校中确定了193名唐氏综合征（DS）儿童和154名具有相似残疾程度的儿童。在两组中，在瑞特量表或附加行为检查表上得分高的儿童比例相似。异常行为在两组智力发育迟缓儿童中都明显比其年龄稍小的兄弟姐妹更常见；31%的DS儿童和29%的对照组儿童被判定适应良好，而38%的DS儿童和49%的对照组儿童有明显的行为障碍。品行障碍在DS儿童中最为常见。“精神病”是对照组中最常见的诊断标签，但在DS儿童中也有发现。
