title: Expressive Language Intratest Scatter of Preschool-Age Children Who Stutter.
abstract: OBJECTIVE
  The purpose of this study was to assess intratest scatter (variability) on standardized tests of expressive language by preschool-age children who do (CWS) and do not stutter (CWNS).
  
  
  METHODS
  Participants were 40 preschool-age CWS and 46 CWNS. Between-group comparisons of intratest scatter were made based on participant responses to the Expressive subtest of theTest of Early Language Development - 3(TELD-Exp; Hresko, Reid, & Hamill, 1999) and theExpressive Vocabulary Test 2(EVT-2; Williams, 2007). Within-group correlational analyses between intratest scatter and stuttering frequency and severity were also conducted for CWS.
  
  
  RESULTS
  Findings indicated that, for CWS, categorical scatter on the EVT-2 was positively correlated with their stuttering frequency. No significant between-group differences in intratest scatter were found on the TELD-Exp or the EVT-2.
  
  
  CONCLUSIONS
  Consistent with earlier findings, variability in speech-language performance appears to be related to CWS' stuttering, a finding taken to suggest an underlying cognitive-linguistic variable (e.g., cognitive load) may be common to both variables.
