The Fluharty Preschool Speech and Language Screening Test: a population-based validation study using...

Area of Science:

• Speech-Language Pathology
• Developmental Psychology
• Pediatric Audiology

Background:

• Accurate screening tools are crucial for early identification of speech and language disorders in preschool children.
• The Fluharty Preschool Speech and Language Screening Test is a widely used tool for this purpose.
• Validation studies are essential to determine the clinical utility of screening instruments.

Purpose of the Study:

• To clinically validate the Fluharty Preschool Speech and Language Screening Test.
• To assess the test's sensitivity, specificity, and predictive value for identifying speech and language impairments in 4- and 5-year-old children.
• To compare the screening performance for language disorders versus articulation impairments.

Main Methods:

• Two cohorts of 700 preschool children (4- and 5-year-olds) were screened using the Fluharty test.
• Stratified samples from each cohort underwent criterion testing for articulation and language.
• Clinical validation indices including sensitivity, specificity, and predictive value were calculated.

Main Results:

• The Fluharty test demonstrated low sensitivity for language outcomes (0.43 and 0.31) but higher sensitivity for articulation impairments.
• Specificity was high (0.82 and 0.93), indicating good ability to correctly identify children without disorders.
• Overreferral rates were 14% and 5%, with underreferral at 14% for both cohorts.

Conclusions:

• The Fluharty Preschool Speech and Language Screening Test is not sensitive enough for reliable screening of language disorders in preschoolers.
• The test shows potential for identifying children with articulation impairments.
• Further research may be needed to refine screening protocols or explore alternative measures for language disorders.
