Study on the Reliability and Validity of the Vocabulary Assessment Sub-Scale of Children's Language Development
Develop and validate a Chinese Language Development Vocabulary Assessment Scale for children.
Methods
2
Utilizing convenience sampling
906 children aged 2.5 to 6.5 years from various kindergartens and 101 children with developmental speech or language disorders were evaluated using this scale. Results Statistical analyses
including item analysis
and tests for reliability and validity were performed.
Results
2
The research showed that
except for one vocabulary comprehension question
all other items demonstrated statistical significance. Exploratory factor analysis revealed four common factors each for vocabulary comprehension and expression
with cumulative contribution rates of 54% and 45%
respectively. The scale includes 20 vocabulary comprehension questions and 25 vocabulary expression questions
with good internal consistency reliability and split-half reliability coefficients.
Conclusion
2
The scale is a reliable and effective tool for assessing vocabulary development in Chinese preschoolers and offers a valuable resource for diagnosing and treating speech or language disorders in children.
