[Stuttering in childhood: etiology and follow-up. Initial results of a 5-year longitudinal study].
For about 15 months a multifactorial longitudinal study on the development of stuttering in preschool children has been conducted at the Phoniatric Outpatient Department of the University of Ulm. The main subject of the study is to determine valid indicators to estimate the risk of future chronicity or remission of stuttering and to find out whether and how it is possible to differentiate normal developmental dysfluencies from chronic abnormal dysfluencies. Preliminary results are presented and discussed.
