A randomized controlled trial was conducted of a whole-service cohort of children referred to the Paediatric Speech and Language Therapy Service of Middlesbrough Primary Care Trust between January 1999 and April 2000. The 730 children involved, aged up to 16 years, were diagnosed with primary speech and/or language impairment in the absence of any learning, physical or sensory difficulty.
The study considered outcomes of treatment versus no treatment.
METHODS & PROCEDURES: Treatment involved clinic-based interventions, provided according to local departmental criteria and care pathways, averaging 5.5 h (range 0-24 h) of contact during the 6-month period immediately following initial assessment. Assessments occurred within 8 weeks of referral and intervention began immediately thereafter.
OUTCOMES & RESULTS: Treatment was significantly more effective than no treatment, over 6 months, both overall (p < 0.001) and for each of the three diagnostic categories (comprehension, expression and speech, each p < 0.001).
An average of 6 h of speech and language therapy in a 6-month period can produce significant improvement in performance, and it has been shown to be more effective than no treatment over the same 6-month period for children with primary speech and/or language impairment.
1999年1月至2000年4月期间，对转介至米德尔斯堡初级保健信托基金儿科言语和语言治疗服务部门的全体儿童队列进行了一项随机对照试验。所涉及的730名儿童年龄在16岁以下，被诊断为原发性言语和/或语言障碍，且无任何学习、身体或感官困难。
该研究比较了治疗与不治疗的效果。
治疗包括基于诊所的干预措施，根据当地部门标准和护理路径提供，在初次评估后的6个月内平均接触时长为5.5小时（范围为0 - 24小时）。评估在转诊后8周内进行，评估后立即开始干预。
在6个月的时间里，总体而言（p < 0.001）以及在三个诊断类别（理解、表达和言语，每个类别p < 0.001）中的每一个类别中，治疗都比不治疗显著更有效。
在6个月内平均进行6小时的言语和语言治疗可以显著提高表现，并且已证明对于患有原发性言语和/或语言障碍的儿童，在相同的6个月期间内，治疗比不治疗更有效。
