Deaf children of hearing parents (DOH) are at risk for early language delays (ELD) due to environmental and etiological factors, compounding the previously reported higher incidence of ELD in deaf children of deaf parents (DOD) compared to the general population. Archival data from the online database of the Visual Communication and Sign Language Checklist yielded 147 ratings of DOH 3- to 5-year-old children whose parents reported American sign language (ASL) being used in the home at least equally to spoken language. Research goals included (1) examining the incidence of ELD in this cohort, (2) investigating differences in outcomes based on the scaling method used, (3) exploring patterns among the ratings of DOH children identified with ELD, (4) comparing the DOH outcomes to published DOD data, and (5) investigating differences between ratings and individual children. The DOH outcomes suggested an incidence of ELD twice that of the previous DOD sample, with a higher percentage of more severe delays. Even DOH children not identified with ELD demonstrated less well-developed ASL skills than their DOD peers. This emphasizes the need for ongoing monitoring of early ASL skills to allow for early identification of needs and adjustment of interventions to address ASL development.
听力正常的父母所生的聋儿（DOH）由于环境和病因因素，面临早期语言发育迟缓（ELD）的风险，这使得之前报道的聋人父母所生的聋儿（DOD）与普通人群相比，ELD发病率更高的情况更加复杂。来自视觉交流和手语清单在线数据库的存档数据产生了147份对3至5岁DOH儿童的评分，这些儿童的父母报告说，美国手语（ASL）在家庭中的使用频率至少与口语相同。研究目标包括：（1）检查该队列中ELD的发病率；（2）根据所使用的评分方法调查结果差异；（3）探索被确定为ELD的DOH儿童评分中的模式；（4）将DOH的结果与已发表的DOD数据进行比较；（5）调查评分与个体儿童之间的差异。DOH的结果表明，ELD的发病率是之前DOD样本的两倍，更严重延迟的比例更高。即使是未被确定为ELD的DOH儿童，其ASL技能的发展也不如他们的DOD同龄人。这强调了持续监测早期ASL技能的必要性，以便能够早期识别需求并调整干预措施以解决ASL发展问题。
