Summary
A new speech disorder screening test, Terdaf, was validated in Brazilian children. While initial specificity was moderate, adjustments improved it, suggesting its utility for early detection by professionals.
Area of Science:
- Speech-Language Pathology
- Pediatric Health
- Screening Test Validation
Background:
- Early detection of speech disorders is crucial for child development.
- Existing screening tools may require validation for specific populations.
- The Terdaf test was developed by Brazilian researchers to address this need.
Purpose of the Study:
- To present validation data for the Terdaf speech disorder screening test.
- To assess the sensitivity and specificity of the Terdaf test in a Brazilian elementary school population.
Main Methods:
- Probabilistic cluster sampling of 2,027 first-grade children in Canoas, Brazil.
- Re-evaluation of 200 children by an expert to determine Terdaf's sensitivity and specificity.
- Analysis of specificity adjustments when excluding children with speech disorders due to sociocultural factors.
Main Results:
- The prevalence of speech disorders in the sample was 26.7%.
- Terdaf demonstrated a sensitivity of 81.6% and an initial specificity of 44.4%.
- Excluding sociocultural factors significantly increased specificity to 74.1%.
Conclusions:
- The Terdaf test is a quick and easy-to-apply tool for speech disorder screening.
- It can aid education and health professionals in early diagnosis and prevention of comorbidities.
- Minor adjustments are recommended for optimal application of the Terdaf test.

01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:25Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
