The study investigated the outcome of a word-web intervention for children diagnosed with word-finding difficulties (WFDs).
Twenty children age 6-8 years with WFDs confirmed by a discrepancy between comprehension and production on the Test of Word Finding-2, were randomly assigned to intervention (n = 11) and waiting control (n = 9) groups. The intervention group had six sessions of intervention which used word-webs and targeted children's meta-cognitive awareness and word-retrieval.
On the treated experimental set (n = 25 items) the intervention group gained on average four times as many items as the waiting control group (d = 2.30). There were also gains on personally chosen items for the intervention group. There was little change on untreated items for either group.
The study is the first randomised control trial to demonstrate an effect of word-finding therapy with children with language difficulties in mainstream school. The improvement in word-finding for treated items was obtained following a clinically realistic intervention in terms of approach, intensity and duration.
本研究调查了针对被诊断为找词困难（WFDs）儿童的词网干预效果。
20名6 - 8岁被《找词测试 - 2》中理解与表达差异确诊为有找词困难的儿童，被随机分为干预组（n = 11）和等待对照组（n = 9）。干预组进行了六次使用词网的干预，目标是提高儿童的元认知意识和词汇检索能力。
在经过处理的实验组（n = 25个项目）中，干预组平均获得的项目数量是等待对照组的四倍（d = 2.30）。干预组在个人选择的项目上也有进步。两组在未处理的项目上变化不大。
本研究是首个随机对照试验，证明了在主流学校中对有语言困难儿童进行找词治疗的效果。在方法、强度和持续时间方面进行符合临床实际的干预后，治疗项目的找词能力得到了改善。
