Product Details

The Stuttering Severity Instrument for Children and Adults—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 behaviour:

  • frequency
  • duration
  • physical concomitants, and
  • naturalness of the individual's speech.

Frequency is expressed in percent syllables stuttered and converted to scale scores of 2-18. Duration is timed to the nearest 1/10 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 instrument was normed on a sample of 72 preschool-aged children, 139 schoolaged children, and 60 adults. It can also be used in conjunction with the Stuttering Prediction Instruments for Young Children (SPI).

CSSS–2.0 Scoring Software

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