Deaf and hard-of-hearing (DHH) children may experience difficulties in word decoding development.
We aimed to compare and predict the incremental word decoding development in first grade in Dutch DHH and hearing children, as a function of kindergarten reading precursors.
In this study, 25 DHH, and 41 hearing children participated. Kindergarten measures were phonological awareness (PA), letter knowledge (LK), rapid naming (RAN), and verbal short-term memory (VSTM). Word decoding (WD) was assessed at three consecutive time points (WD1, 2, 3) during reading instruction in first grade.
The hearing children scored higher than the DHH children on PA and VSTM only, although the distribution of WD scores differed between the groups. At WD1, PA and RAN predicted WD efficiency in both groups; but PA was a stronger predictor for hearing children. At WD2, LK, RAN, and the autoregressor were predictors for both groups. While at WD3, only the autoregressor was a significant predictor.
WD development in DHH children on average shows similar levels as in hearing children, though within the DHH group more variation was observed. WD development in DHH children is not as much driven by PA; they may use other skills to compensate.
失聪和重听（DHH）儿童在单词解码能力发展方面可能会遇到困难。
我们旨在比较并预测荷兰一年级DHH儿童和听力正常儿童在单词解码能力上的渐进发展情况，这是幼儿园阅读基础能力的一个函数。
在本研究中，25名DHH儿童和41名听力正常儿童参与其中。幼儿园阶段的测量指标包括语音意识（PA）、字母知识（LK）、快速命名（RAN）和言语短期记忆（VSTM）。在一年级阅读教学期间的三个连续时间点（WD1、WD2、WD3）对单词解码（WD）进行评估。
只有在语音意识和言语短期记忆方面，听力正常儿童的得分高于DHH儿童，尽管两组之间单词解码得分的分布有所不同。在WD1时，语音意识和快速命名预测了两组的单词解码效率；但语音意识对听力正常儿童来说是更强的预测指标。在WD2时，字母知识、快速命名和自回归变量是两组的预测指标。而在WD3时，只有自回归变量是显著的预测指标。
平均而言，DHH儿童的单词解码能力发展水平与听力正常儿童相似，不过在DHH儿童组中观察到了更多的差异。DHH儿童的单词解码能力发展并非主要由语音意识驱动；他们可能会使用其他技能来进行补偿。
