A sample of 99 early treated phenylketonuric children showed higher levels of behavioural deviance than 197 matched controls. For boys this excess of behavioural deviance persisted when IQ was taken into account. For phenylketonuric girls however it was restricted to those with IQs less than 70. The type of behavioural deviance shown by the boys over the whole IQ range was predominantly neurotic. The levels of behavioural deviance found in phenylketonuric children were among the highest that have been reported for children with various handicapping conditions.
99名早期接受治疗的苯丙酮尿症儿童样本显示，其行为偏差水平高于197名匹配的对照组儿童。对于男孩来说，在考虑智商因素后，这种行为偏差仍然存在。然而，对于苯丙酮尿症女孩而言，这种情况仅限于智商低于70的女孩。在整个智商范围内，男孩表现出的行为偏差类型主要是神经质型。苯丙酮尿症儿童的行为偏差水平在已报道的患有各种残疾状况的儿童中处于最高水平之列。
