title: Language Sampling for Preschoolers With Severe Speech Impairments.
abstract: The purposes of this investigation were to determine if measures such as mean length of utterance (MLU) and percentage of comprehensible words can be derived reliably from language samples of children with severe speech impairments and if such measures correlate with tools that measure constructs assumed to be related.
  
  
  
  Language samples of 15 preschoolers with severe speech impairments (but receptive language within normal limits) were transcribed independently by 2 transcribers. Nonparametric statistics were used to determine which measures, if any, could be transcribed reliably and to determine if correlations existed between language sample measures and standardized measures of speech, language, and cognition.
  
  
  
  Reliable measures were extracted from the majority of the language samples, including MLU in words, mean number of syllables per utterance, and percentage of comprehensible words. Language sample comprehensibility measures were correlated with a single word comprehensibility task. Also, language sample MLUs and mean length of the participants' 3 longest sentences from the MacArthur-Bates Communicative Development Inventory (Fenson et al., 2006) were correlated.
  
  
  
  Language sampling, given certain modifications, may be used for some 3-to 5-year-old children with normal receptive language who have severe speech impairments to provide reliable expressive language and comprehensibility information.
