In an earlier randomized clinical trial, daily communication and language therapy resulted in more favorable spoken vocabulary outcomes than weekly therapy sessions in a subgroup of initially nonverbal preschoolers with intellectual disabilities that included only children with Down syndrome (DS). In this reanalysis of the dataset involving only the participants with DS, we found that more therapy led to larger spoken vocabularies at posttreatment because it increased children's canonical syllabic communication and receptive vocabulary growth early in the treatment phase.
在一项早期的随机临床试验中,每日的沟通和语言治疗在包括唐氏综合征(Down syndrome,DS)患儿在内的仅有轻度智障的非语言学龄前儿童亚组中,相较于每周治疗,产生了更有利的口语词汇结果。在仅涉及 DS 参与者的数据集的此次重新分析中,我们发现,更多的治疗导致了更大的口语词汇量,因为它在治疗早期增加了儿童的规范音节沟通和接受性词汇增长。
