本研究采用一份关于发展性语言障碍治疗史的问卷，评估有语言障碍和无语言障碍的二年级儿童直系亲属中这些问题的普遍程度。从这些家庭获得的数据有力地证明，这些语言问题不是随机分布在家庭中，而是倾向于集中在家庭内部。虽然所有语言障碍二年级学生的家庭成员比正常二年级学生的家庭成员表现出语言障碍的几率大大增加，但在家庭成员中存在相当大范围的语言障碍几率增加。具体来说，与父母相比，兄弟和姐妹（在较小程度上）与语言障碍的家族关联更高。这些结果表明，造成发育性语言障碍的因素至少在一定程度上与家庭有关。
A questionnaire concerning the history of treatment of developmental language disorder was used to evaluate the prevalence of these problems within the immediate family members of second-grade children with and without language impairment. The data obtained from these families revealed strong evidence that such language problems are not randomly distributed across families but rather tend to concentrate within families. Although all family members of the language-impaired second graders demonstrated substantially increased odds for language impairment over those who came from families with normal second graders, a considerable range of increased odds for language impariment existed among the family members. Specifically, brothers and to a lesser degree sisters had a higher familial association with language impairment than did the parents. These results suggest that the factors that contribute to developmental language disorders are at least in part associated with the family unit.
