The goals of the present study were to (1) examine the effects of the multiple opposition phonological approach on improving phoneme production accuracy in children with severe phonological disorders and (2) explore whether the multiple opposition approach is feasible for the telepractice service delivery model. A multiple-baseline, single-participant design replicated across two children, was implemented. Two male children who resided in rural areas of West Texas in the USA participated. One child was 4 years and 10 months old and the other child was 6 years old. Both of the children were diagnosed with phonological disorders without any sensory, motoric, or intellectual disabilities. The children’s articulation was tested using Goldman–Fristoe Articulation Test-2 and probes were administered across the period of the study. The children received a 30-minute phonological intervention via telepractice twice a week for 12 or 16 weeks. An increasing trend for production accuracy for target sounds was observed during intervention for both children. Maintenance also was observed at 2-week and 2-month follow-ups. Standard scores from a standardized articulation test increased during posttest compared to pretest. The multiple opposition phonological approach can lead to improved speech production accuracy in children with severe phonological disorders. Telepractice may be an effective context for a phonological intervention approach as has been found for other domains of speech and language intervention and a useful service delivery model to underserved children with speech disorders who are unable to access a speech pathologist due to various circumstances.

美国西德克萨斯农村地区2例重度音位障碍患儿远程练习多重对立音位法治疗效果

本研究的目标是（1）检查多重对立语音方法对提高严重语音障碍儿童音素产生准确性的影响，以及（2）探讨多重对立方法是否适用于远程练习服务交付模型。实施了跨两个孩子复制的多基线、单参与者设计。两名居住在美国西德克萨斯农村地区的男孩参加了此次活动。一个孩子 4 岁 10 个月大，另一个孩子 6 岁。这两个孩子都被诊断出患有语音障碍，没有任何感觉、运动或智力障碍。使用 Goldman-Fristoe Articulation Test-2 测试儿童的发音，并在整个研究期间使用探针。孩子们每周两次通过远程练习接受 30 分钟的语音干预，持续 12 或 16 周。在对这两个孩子的干预期间，观察到目标声音的产生准确度有增加的趋势。在 2 周和 2 个月的随访中也观察到了维持情况。与前测相比，后测期间标准化发音测试的标准分数有所增加。多重对立语音方法可以提高严重语音障碍儿童的语音生成准确性。Telepractice 可能是语音干预方法的有效背景，正如在其他语音和语言干预领域中发现的那样，并且是一种有用的服务提供模型，用于因各种情况而无法联系语言病理学家的语言障碍儿童。
