Differentially Diagnosing Stuttering in Young Children Using the Stuttering Severity Instrument

Abstract

Young children between the ages of two and six years often exhibit partword, whole word. and phrases repetitions as their language develops. This is also the age range when stuttering most frequently appears. Consequently. speech-language pathologists need diagnostic criteria and evaluation tools to distinguish between the incipient stutterer and the normally disfluent child. Today a widely used evaluation tool is the Stuttering Severity Instrument (SSI) (Riley, 1972, 1980). The SSI is designed to provide a severity level based upon the parameters of frequency. duration. and physical concomitants. Riley (1972) first designed the SSI to not include monosyllabic word repetitions in the frequency count: however. he revised the SSI in 1980 to include monosyllabic word repetitions without providing new normative data nor standardization. It was questionable as to whether the SSI was a sufficiently sensitive means to determine stuttering severity for young children and to whether or not it was strengthened or weakened by the addition of whole monosyllabic words
