Mean Length of Communication in Words (MLCU), Number of Different Words (NDW) and Total Number of Words (TNW) were obtained using SALT with the transcript of all 6 stories. SALT calls these MLU-W, No. of Different Word Roots, and No. Main Body Words (the last two are under TTR for the whole transcript -- not TTR for 50 or 100 utterances). The entire transcript was used for these measures. The Analysis Set was set to exclude the following: abandoned and interrupted utterances, unintelligible utterances, nonverbal utterances, and yes/no responses to questions.
Although there is a table for 6 year olds, MLCU and CI do not discriminate well between children with and without language impairments at 6 years, and thus scores should be used with particular caution.
* Be sure to change only the numbers in the red boxes.
