School-aged children with persisting speech sound disorders (SSDs) may show little improvement in speech accuracy following phonological or articulation therapy.
To determine the effects of establishing consonant production in facilitative vowel contexts for a 7-year-old boy (CD) with persisting post-alveolar fronting. CD had received phonological awareness therapy and traditional articulation therapy as part of a community caseload. However, his post-alveolar fronting showed resistance to therapy.
METHODS & PROCEDURES: CD received individual therapy for nine 45-55-min sessions. A checklist of quality indicators for single-subject research was used to explore the likelihood that a community clinic could meet quality indicators. Fifteen test words in each of target, generalization and control sets were measured at five times pre-, during and post-therapy. A trend analysis was used to measure the statistical significance of the results and to demonstrate the efficacy of therapy.
OUTCOMES & RESULTS: Therapy was successful. Gains on treatment and generalization test items were rapid and significantly higher than gains on control test items. Only three of 21 single-subject research quality indicators were not met in this research.
CONCLUSIONS & IMPLICATIONS: Targeting facilitative vowel contexts was successful for this 7-year-old boy with persisting post-alveolar fronting which had been resistant to other therapy techniques. Speech and language therapists are encouraged to ensure that quality indicators for single-subject interventions are built into regular practice.
持续存在语音障碍（SSD）的学龄儿童在接受语音或构音治疗后，言语准确性的改善可能不大。
确定在促进元音环境中建立辅音产生对 7 岁男孩（CD）持续性后齿龈前化的影响。CD 已经接受了语音意识治疗和传统的构音治疗，作为社区病例的一部分。然而，他的后齿龈前化对治疗有抵抗力。
CD 接受了为期 9 次、每次 45-55 分钟的个体治疗。使用了一份用于单例研究的质量指标检查表，以探讨社区诊所是否能够满足质量指标。在治疗前、治疗中和治疗后五个时间点，分别测量目标、泛化和控制组中的 15 个测试词。趋势分析用于测量结果的统计学意义，并展示治疗的效果。
治疗是成功的。治疗和泛化测试项目的收益迅速且显著高于控制测试项目的收益。在这项研究中，只有 21 个单例研究质量指标中的三个没有得到满足。
针对促进元音环境的治疗对这个持续存在后齿龈前化的 7 岁男孩是成功的，这对其他治疗技术有抵抗力。鼓励言语和语言治疗师确保单例干预的质量指标纳入常规实践。
