目的：当一种行为治疗普遍有效时，研究的核心问题就转向了最佳剂量给药。在这项研究中，我们确定是否一个有效的治疗方法可以通过增加剂量密度更有效。方法对20例患儿采用增强会话重铸法治疗形态学错误。一半在半小时内接受24剂（约1剂/1.25分钟），另一半在15分钟内接受相同数量的剂量（约1剂/38秒）。在整个治疗过程和6周的随访中，对语素使用的泛化进行了调查。对处理过的语素的自发使用也进行了跟踪。结果：虽然治疗总体上是有效的，但在任何结果测量上，治疗条件之间没有显着差异。随访表现与治疗期结束时的表现显著相关。结论组间差异极小，说明在治疗过程中，将剂量率压缩到一半的时间内，高密度给药方法的给药效果不受影响，使高密度给药方法成为一种更有效的给药方法。这可以在治疗期间腾出时间来实现其他目标，或者为孩子提供更多的课堂教学时间。补充Materialhttps: / / doi.org/10.23641/asha.8968559
PurposeWhen a behavioral treatment is generally efficacious, the central research questions shift to optimized dose delivery. In this study, we determine whether a validated treatment method can be made more effective or efficient by increasing the dose density employed.MethodTwenty children were treated with Enhanced Conversational Recast methods to treat morphological errors. Half received 24 doses per session within a half hour (approximately 1 dose/1.25 min), and the other received the same number of doses within 15 min (approximately 1 dose/38 s). Generalization of morpheme use was probed throughout treatment and at a 6-week follow-up. Spontaneous use of treated morphemes was also tracked.ResultsAlthough the treatment was effective overall, there were no significant differences between treatment conditions on any of the outcome measures. Follow-up performance correlated significantly with performance at the end of the treatment period.ConclusionMinimal between-groups differences suggest that performance does not suffer when dose rates are compressed into half the time during treatment, making the high-density dose delivery method a more efficient delivery method. This could make time available within a treatment session to address other goals or allow for more classroom instructional time for the child.Supplemental Materialhttps://doi.org/10.23641/asha.8968559
