Area of Science:

  • Neuroscience
  • Psychology
  • Speech-Language Pathology

Background:

  • Stuttering is a complex speech disorder with potential links to neurological and psychological factors.
  • Understanding the prevalence and associated conditions in diverse populations is crucial for effective intervention.

Purpose of the Study:

  • To determine the prevalence of self-reported stuttering among Spanish-speaking university students.
  • To investigate the relationship between stuttering and central nervous system risk factors, associated disorders, and depression symptoms.

Main Methods:

  • A questionnaire was administered to 1879 Spanish-speaking university students (mean age 24.0).
  • The questionnaire assessed self-reported stuttering, central nervous system risk factors, associated disorders (allergies, headache, dyslexia, substance use), and depression symptoms.

Main Results:

  • A prevalence of 2% for self-reported stuttering was identified in the sample.
  • Self-reported stutterers exhibited a higher prevalence of minor brain injury/dysfunction, developmental dyslexia history, word-finding difficulties, and depressive symptoms compared to non-stutterers.

Conclusions:

  • Self-reported stuttering in university students is associated with a higher likelihood of neurological and psychological conditions.
  • Findings suggest a potential link between stuttering and factors such as brain injury, dyslexia, and depression, warranting further investigation.
