Stuttering Severity Instrument

The Stuttering Severity Instrument (SSI) is a standardized assessment tool used by speech-language professionals to measure the severity of a person's stuttering. It evaluates aspects such as the number of stuttering moments, physical escape behaviors (like unusual movements), and how the stuttering affects communication. The results help clinicians understand the impact of stuttering on an individual’s speech and determine appropriate treatment strategies. Essentially, it provides a clear, consistent way to assess how severe someone’s stuttering is, guiding personalized therapy to improve fluency and communication confidence.
