PURPOSE This study evaluates the initial efficacy of Chaining SPeech Lessons in Intensive Ten-minute Sessions (SPLITS), an alternative service delivery model for the Speech Motor Chaining treatment approach. We hypothesized that Chaining SPLITS would result in improvements in /ɹ/ accuracy on syllables and untrained words when compared to a no-treatment condition. METHOD Within a randomized controlled trial, thirteen 7-9-year-old children with difficulty producing /ɹ/ were randomized to receive treatment either immediately or after an 8-week delay. Treatment sessions were conducted 4 times a week over 8 weeks. Syllable and word-level recordings were collected at the baseline, 8-week, and 16-week time points. Recordings were rated along a 5-point scale by three masked, independent listeners. The primary outcome was changed score from the baseline to 8-week time point (Interval 1) and 8-week to 16-week time point (Interval 2). RESULTS Linear mixed modeling revealed that Chaining SPLITS led to significantly greater improvement in /ɹ/ accuracy at the syllable level for active treatment compared to a period of no treatment. This improvement was replicated in both groups. There was not sufficient evidence of an effect of Chaining SPLITS on untrained words after 8 weeks of treatment. CONCLUSIONS The current study provides initial evidence of the effectiveness of 8 weeks of Chaining SPLITS on improvement in /ɹ/ accuracy in syllables. Short, frequent sessions may be a viable approach to promote acquisition of /ɹ/ among school-age children; however, longer courses of treatment may be needed to observe further improvement at the word level.

十分钟会议中的演讲：链接 SPLITS 服务交付模型的试点随机对照试验。


目的 本研究评估了在强化十分钟会话中链接 SPeech 课程 （SPLITS） 的初始疗效，这是一种语音运动链接治疗方法的替代服务交付模型。我们假设与无处理条件相比，链接 SPLITS 会导致音节和未经训练的单词的 /ɹ/ 准确性提高。方法 在一项随机对照试验中，13 名难以产生 /ɹ/ 的 7-9 岁儿童被随机分配接受立即治疗或延迟 8 周后接受治疗。治疗在 8 周内每周进行 4 次。在基线、 8 周和 16 周的时间点收集音节和单词水平的录音。录音由 3 名戴面具的独立听众按照 5 分制进行评分。主要结果是将评分从基线更改为 8 周时间点 （Interval 1） 和 8 周至 16 周时间点 （Interval 2）。结果 线性混合模型显示，与不治疗期间相比，链接 SPLITS 导致积极治疗在音节水平上 /ɹ/ 准确性的显著提高。这种改善在两组中都得到了复制。没有足够的证据表明 Chaining SPLITS 在治疗 8 周后对未经训练的单词有影响。结论 目前的研究提供了初步证据，证明 8 周的 Chaining SPLITS 对提高音节 /ɹ/ 准确性的有效性。短时间、频繁的会议可能是促进学龄儿童获得 /ɹ/ 的可行方法;然而，可能需要更长的治疗疗程才能观察到 WORD 水平的进一步改善。补充材料 https://doi.org/10.23641/asha.27868800。
