Purpose The purpose of this meta-analysis was to identify, integrate and summarize evidence from empirical studies of the language abilities of children who do (CWS) and do not (CWNS) stutter. Method Candidate studies were identified through electronic databases, the table of contents of speech-language journals, and reference lists of relevant articles and literature reviews. The 22 included studies met the following criteria: studied both children who do and do not stutter between 2;0 to 8;0 years of age and reported norm-referenced language measures and/or measures from spontaneous language samples amenable to effect size calculation. Data were extracted using a coding manual and assessed by application of general and specialized analytical software. Mean difference effect size was estimated using Hedges’ g (Hedges, 1982). Results Findings indicated that CWS scored significantly lower than CWNS on norm-referenced measures of overall language (Hedges’ g = −0.48), receptive (Hedges’ g = −0.52) and expressive vocabulary (Hedges’ g = −0.41) as well as mean length of utterance (MLU) (Hedges’ g = −0.23). Conclusions Present findings were taken to suggest that children’s language abilities are potentially influential variables associated with childhood stuttering.
