Twenty-four children between 4 years 5 months and 8 years of age with unintelligible spontaneous speech and at least average nonverbal intelligence were evaluated over a period of several hours. Nine of the children (37%) were found to have a psychiatric disorder, either a disturbance of emotions specific to childhood (ICD code 313) or a hyperkinetic syndrome (ICD code 314). No relationship was found between the presence of such a disorder and the severity of the speech/language disorder.
对24名年龄在4岁5个月至8岁之间、自发言语难以理解且至少具有平均非言语智力的儿童进行了长达数小时的评估。其中9名儿童（37%）被发现患有精神疾病，要么是儿童特有的情绪障碍（国际疾病分类代码313），要么是多动综合征（国际疾病分类代码314）。未发现此类疾病的存在与言语/语言障碍的严重程度之间存在关联。
