The Stuttering Severity Instrument, Fourth Edition (SSI-4) is a reliable and valid norm-referenced stuttering assessment that can be used for both clinical and search purposes. It measures stuttering severity in both children and adults in the four areas of speech behavior: (1) frequency, (2) duration, (3) physical concomitants, and (4) naturalness of the individual’s speech. Frequency is expressed in percent of syllables stuttered and converted to scale scores of 2–18. Duration is timed to the nearest one-tenth of a second and converted to scale scores of 2–18. The four types of Physical Concomitants are converted to scale scores of 0–20.

The SSI-4 can also be used in conjunction with the Stuttering Prediction Instruments for Young Children (SPI).

The SSI-4 was normed on a sample of 72 preschool-aged children, 139 school-aged children, and 60 adults. It has four components, each of which is used to assess and monitor stuttering severity in both children and adults for clinical and research use: (1) Examiner’s Manual and Picture Plates, (2) Test Record and Frequency Computation Forms, (3) Subjective Stuttering Scales, and (4) Computerized Scoring of Stuttering Severity (Software Version 2.0).

The Computerized Scoring of Stuttering Severity (Version 2; CSSS 2.0) software is provided to facilitate the calculation of frequency and duration. The CSSS 2.0 automatically produces a record of the percentage of syllables stuttered (frequency) and the duration of the three longest stuttering events.
