The purpose of this study was to describe the Language Access Profile Tool (LAPT) and its psychometric properties with the aim of evaluating its suitability as an alternative to the deaf or hard of hearing (DHH) Language Exposure Assessment Tool (D-LEAT) in clinical practice with DHH children age 12 years and younger.
We administered both the LAPT and D-LEAT to the caregivers of 105 DHH children 12 years old and younger from across the United States, 40% of whom were interviewed again after a delay of at least 1 month. Each interview resulted in a child-specific estimate of their cumulative experience with language input, expressed as a proportion divided across eight categories.
Participants in the sample reported experience with all eight input categories, but four categories were common and four were rare. Estimates for all input categories were consistent at both initial and follow-up interviews. Estimates for each input category were also strongly correlated with the corresponding estimates from the D-LEAT, although correlations for the rare categories should be interpreted cautiously.
The LAPT demonstrates sufficient test-retest reliability and convergent validity to be a useful and more user-friendly alternative to the D-LEAT. We provide recommendations for how the LAPT and the D-LEAT can be best used in their current form.
本研究旨在描述语言访问档案工具（LAPT）及其心理测量学特性，目的是评估其作为替代聋人或重听儿童（DHH）语言接触评估工具（D-LEAT）在临床实践中的适用性，研究对象为年龄在 12 岁及以下的 DHH 儿童。
我们向来自美国各地的 105 名年龄在 12 岁及以下的 DHH 儿童的照顾者同时施测了 LAPT 和 D-LEAT，其中 40%的儿童在至少 1 个月后进行了重测。每次访谈都会对每个孩子的语言输入经历进行具体估计，用一个比例除以八个类别来表示。
样本中的参与者报告了所有八个输入类别的经验，但有四个类别是常见的，四个是罕见的。在初始访谈和随访访谈中，所有输入类别的估计值都是一致的。每个输入类别的估计值与 D-LEAT 对应的估计值也具有很强的相关性，尽管对罕见类别的相关性应谨慎解释。
LAPT 具有足够的重测信度和收敛效度，可以作为 D-LEAT 的有用且更用户友好的替代方法。我们提供了关于如何在当前形式下最好地使用 LAPT 和 D-LEAT 的建议。
