Transcript of SSI-4

Stuttering Severity Instrument-3
To calculate the frequency:

Ultimate Goal
In the best interest of the client, the goal is to build goals based on the client's need and severity of the stuttering. The SSI-3 allows for you to focus on that area of severity.
by Glyndon D. Riley
Riley defines stuttering behaviors as “repetitions or prolongations of sounds or syllables, including silent prolongations, "(Riley, 1994)
The SSI-3 helps clinicians measure the stuttering severity in three areas of speech behavior:
Physical Concomitants.
-Transcribe a 200-500 word sample
- Count the number of stuttered syllables and divide by the total number of syllables
-Multiple that number by 100 to calculate the %
The frequency is expressed as the percent of
syllables stuttered in a speech sample
The Duration Score is the measurement of time,
in seconds, that a stuttering event lasts
To calculate the duration:
-The three longest stuttering events are measured
using a stopwatch
-Then those times are averaged
Physical Concomitants
Rated on a score of 0 to 5 with 0 being not observed and 5 being severe and painful-looking
-Distracting Sounds such as noisy breathing, whistling, and clicking sounds
-Facial Grimaces including jaw jerking, tongue protruding and jaw muscles tense
-Head Movements such as turning away, poor eye contact and constant looking around
-Movements of the Extremities including arm and hand movement, torso movement, and leg movement
Test Age:
The SSI-3 is appropriate for:
preschool children (ages 2-10 to 5-11)
school-age children (ages 6-1 to 16-11)
adults (ages 17-0 and older)
Test Time:
15-20 minutes
SSI-3 Can be used to monitor
It is important to note that the severity rating from the SSI-3 is only one piece of the puzzle.
Clinicians need to use these data
with information collected from
direct observation and client
interview before creating goals
