SSI-4 Complete Kit Stuttering Severity Instrument

The Stuttering Severity Instrument – Fourth Edition (SSI-4) is an instrument designed for the assessment of stuttering severity in children and adults aged 2 to 10 and older. It helps clinicians and researchers measure multiple dimensions of stuttering, providing an objective evaluation of speech fluency and associated behaviors. This tool provides professional teams with a framework that facilitates accurate clinical diagnosis and monitoring and allows them to tailor speech therapy and intervention plans based on individual severity profiles.

Benefits:

• Comprehensive Measurement: Assesses stuttering severity by measuring frequency, duration, physical concomitants, and speech naturalness.

• Norm-Referenced: Provides reliable, standardized scores for objective severity classification.

• Applicable Across Ages: Suitable for both children and adults, supporting longitudinal monitoring.

• Compatibility: Can be used alongside the Stuttering Prediction Instruments for Young Children for enhanced early assessment.

Key Features:

• Frequency: Expressed as percent syllables stuttered and converted to scale scores from 2 to 18.

• Duration: Measures the length of the longest stuttering events timed to the nearest tenth of a second, with scale scores from 2 to 18.

• Physical Concomitants: Four types of associated physical behaviors scored from 0 to 20.

• Speech Naturalness: Evaluates the naturalness of the individual’s speech during assessment.

Applications

Used in clinical speech therapy, research settings, schools, and healthcare environments to assess and monitor stuttering severity for diagnostic and treatment planning purposes.
