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).
