Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include children aged 2-17 and adults 18 years and older who stutter and meet specific diagnostic criteria.
✕Probably not a fit
Patients who do not exhibit stuttering or do not meet the diagnostic criteria for stuttering may not benefit from this study.

What this trial studies
This study investigates the speech, language, and psychosocial factors contributing to stuttering in both monolingual and multilingual speakers. It aims to evaluate innovative treatment methods, including interdisciplinary approaches and telehealth, specifically designed for fluency disorders. The research focuses on understanding the complexities of stuttering and improving clinical training for speech-language pathologists. By addressing these factors, the study seeks to enhance treatment efficacy for individuals who stutter.
Why it matters
Potential benefit: If successful, this study could lead to more effective treatments for stuttering, improving communication skills and quality of life for affected individuals.
How similar studies have gone: While there have been studies on stuttering treatment, this approach combining interdisciplinary methods and telehealth is relatively novel.

Inclusion Criteria: A participant will be considered a child who stutters (ages 2-17 years) if * their parent/caregiver reports concern that their child is a person who stutters, * they exhibit three of more stuttering-like disfluencies (e.g., sound/syllable repetitions, (in)audible sound prolongations, whole-word repetitions) per 300-word speech sample, or * they present with an overall score of 11 or higher on the Stuttering Severity Instrument - 4th Edition (SSI-4). A participant will be considered an adult who stutters (18+ years) if * they report they are a person who stutters, * they have received a formal diagnosis of stuttering from a certified speech-language pathologist, * they exhibit three of more stuttering-like disfluencies (e.g., sound/syllable repetitions, (in)audible sound prolongations, whole-word repetitions) per 300-word speech sample, or * they present with an overall score of 11 or higher on the Stuttering Severity Instrument - 4th Edition (SSI-4).
