This article presents broad preliminary findings from a longitudinal study of stuttering pertaining to differentiation of developmental paths of childhood stuttering, as well as possible early prediction of High Risk, Low Risk, and No Risk for chronic stuttering. More than 100 preschool children who stutter have been closely followed for several years from near the onset of stuttering using a multiple data collection system, with 45 nonstuttering children serving as controls. Thirty-two stuttering and 32 control subjects who have progressed through several stages of the investigation were identified for the present indepth analyses. They represent four subgroups: I. Persistent Stuttering; II. Late Recovery; III. Early Recovery; IV. Control. Comparative data for the groups with special reference to differences in frequency of disfluency, acoustic features, phonologic skills, language development, nonverbal skills, and genetics are presented. The results suggest several promising predictors of recovery and chronicity.
