Purpose: The purpose of this study was to ascertain if there is an association between stuttering severity and behaviors and the expression of temperament characteristics, including precursors of anxiety. Method: We studied temperament characteristics of a prospectively recruited community cohort of stuttering children (N = 173) at ages 3, 4 and 6 years using the Short Temperament Scale. Results: Six of 131 statistical tests of association between stuttering severity and behaviors and temperament traits were statistically significant at the 5% level, which was no more than expected by chance alone. Conclusion: Based on parent responses to the Short Temperament Scale, preschoolers who exhibited different levels of stuttering severity and behaviors did not generally express temperament traits differently from one another. Stuttering severity and stuttering behaviors were not associated with the precursors of anxiety. Overall, taking multiple testing into consideration, results show little evidence of association between stuttering severity and temperament up to 4 years of age or between stuttering behaviors and temperament up to 6 years of age.
