The Stuttering Severity Instrument Manual: A Comprehensive Guide
Hey there readers!
Welcome to our in-depth exploration of the Stuttering Severity Instrument (SSI) manual. This handy tool is designed to assess the severity of stuttering and is widely used by speech-language pathologists and clinicians.
A Closer Look at the SSI Manual
Origins and Development
The SSI manual was developed by a team of researchers led by Dr. Joseph Sheehan in the late 1970s. It was originally intended as a way to measure the severity of stuttering in children, but it has since been adapted for use with adults as well.
Structure and Components
The SSI manual consists of two main components: a parent/caregiver questionnaire and a clinician rating scale. The questionnaire is completed by the child’s parent or caregiver and provides information about the child’s stuttering frequency, duration, and impact on daily life. The clinician rating scale is completed by a speech-language pathologist or clinician after observing the child’s speech. It assesses the severity of stuttering based on objective criteria such as the frequency of disfluencies, the duration of blocks, and the presence of associated physical symptoms.
Applications of the SSI Manual
Diagnosis and Treatment Planning
The SSI manual is used by speech-language pathologists and clinicians to diagnose stuttering and plan treatment. The severity of stuttering can be used to determine the appropriate treatment approach and to track the progress of treatment over time.
Research and Evaluation
The SSI manual is also used by researchers to study stuttering. It provides a standardized way to measure the severity of stuttering, which makes it possible to compare different research studies and to track changes in stuttering severity over time.
Interpretation of the SSI Manual Findings
Percentile Ranks
The SSI manual provides percentile ranks for different stuttering severity scores. This allows clinicians and researchers to compare the severity of a child’s stuttering to the severity of stuttering in other children of the same age.
Clinical Cutoff Scores
The SSI manual also provides clinical cutoff scores that can be used to determine whether a child has mild, moderate, or severe stuttering. These cutoff scores are based on the research literature and can help clinicians make decisions about treatment planning.
SSI Manual Table Breakdown
| Stuttering Severity Level | Percentile Rank | Clinical Cutoff Score |
|---|---|---|
| Mild | 1-25% | 1-10 |
| Moderate | 26-75% | 11-20 |
| Severe | 76-100% | 21-30 |

FAQ about Stuttering Severity Instrument (SSI) Manual
What is the SSI Manual?
The SSI Manual provides instructions and guidelines for using the Stuttering Severity Instrument (SSI), a standardized tool for assessing stuttering severity.
Who should use the SSI Manual?
Speech-language pathologists and other professionals who evaluate stuttering severity.
What does the SSI Manual cover?
- Administration procedures
- Scoring guidelines
- Interpretation of results
- Clinical applications
What are the components of the SSI?
- Interview
- Observation
- Communication Avoidance Scale
How is the SSI administered?
The SSI is typically administered in a clinical setting by a trained professional. It involves an interview, observation of the person’s speech, and completion of a self-assessment scale.
What does the SSI score represent?
The SSI score provides a quantitative measure of stuttering severity, ranging from 1 (mild) to 9 (severe).
How is the SSI score interpreted?
The SSI score helps clinicians make informed decisions about treatment goals and interventions. Higher scores indicate a greater need for support and intervention.
What are the benefits of using the SSI?
- Provides a standardized assessment method
- Facilitates communication between professionals
- Supports evidence-based treatment decisions
Are there any limitations to the SSI?
Like any assessment tool, the SSI has some limitations. It may not be suitable for all individuals who stutter, and it relies on subjective judgments to some extent.
Where can I get the SSI Manual?
The SSI Manual can be purchased from the American Speech-Language-Hearing Association (ASHA) or other professional organizations.
