Predicting Word Reading Deficits Using an App-Based Screening Tool at School Entry.

Area of Science:

• Education
• Developmental Psychology
• Linguistics

Background:

• Reading is crucial for academic success, mental health, and social adaptation.
• Late detection of reading difficulties can lead to long-term disadvantages.
• Early identification of word reading deficits in first grade is key for effective intervention.

Purpose of the Study:

• To develop and validate an economical, accurate, and well-accepted screening tool for early reading difficulties.
• The tool assesses phonological processing, language skills, and non-verbal intelligence in school settings.

Main Methods:

• A screening tool was administered to 409 first graders at the beginning of the school year.
• Data included phonological processing, language skills, and parental information.
• Word reading tests were used for follow-up assessment at the end of the first grade.

Main Results:

• A five-variable screening tool accurately predicted word reading speed deficits (AUC = 0.78).
• Key predictors included letter knowledge, rapid naming, phonological awareness, receptive vocabulary, and morphosyntax.
• The tool was well-accepted by children and screeners and could be administered efficiently.

Conclusions:

• An app-based screening tool assessing phonological processing and language skills can predict word reading deficits at the end of first grade.
• Further validation is needed for the screening instrument in German orthography.
• Early screening facilitates timely interventions for children at risk of reading difficulties.
