目的 了解语言障碍儿童的智能发育特征。方法 对300例语言障碍儿童进行Gesell发育量表评估，了解其运动能、应物能、言语能、应人能4个能区的发育商。结果 300例儿童的运动能平均发育商正常，应物能、言语能及应人能平均发育商均低于正常。运动能、应物能、应人能异常的比例分别为31.0%、49.0%、52.7%。言语能发育商与其他3个能区发育商显著正相关 （r分别为0.506、0.644、0.711，P < 0.01）。结论 语言障碍儿童往往不是单纯的语言落后，而是常伴随运动能力、适应行为及社交行为等方面的落后，应对其进行诊断性的智能发育评估并对伴随的其他发育异常问题进行全面干预。

Objective To investigate the features of intellectual development in children with language disorder. Methods The developmental quotients (DQs) of motor, object, language and social abilities were evaluated in 300 children with language disorder by Gesell Developmental Schedules. Results All the 300 children had normal mean DQs of motor ability and lower mean DQs of object, language, and social abilities. Of all children, 31.0% had abnormal motor ability, 49.0% had abnormal object ability, and 52.7% had abnormal social ability. The DQ of language ability was significantly positively correlated with the DQs of the other three abilities (r=0.506, 0.644, and 0.711 respectively, P < 0.01). Conclusions Children with language disorder may have abnormal motor ability, adaptive behavior, and personal-social behavior. Diagnostic intellectual development evaluation and comprehensive intervention for other developmental abnormalities should be performed for these children.
