Home Literacy Environment and Language Skills in Children with Down Syndrome

Amelia Hickman's research dataset explores the relationship between home literacy practices and vocabulary development in children with Down syndrome. The data includes measures of HLE richness and child engagement during shared book reading, collected via questionnaires from parents of children aged 2 years 11 months to 6 years 10 months. Language skills were assessed at two time points approximately 9 months apart using a vocabulary checklist and a standardized expressive vocabulary measure.

Use Cases

• Analyzing correlations between child engagement during shared book reading and concurrent expressive vocabulary scores.
• Investigating longitudinal effects of home literacy environment richness on vocabulary development over a 9-month period.
• Modeling predictors of language skill variability among children with Down syndrome based on environmental factors.

Strengths

• Includes longitudinal data collected at two time points approximately 9 months apart.
• Provides descriptive statistics for key variables: HLE richness (M=32.76, SD=6.83) and child engagement (M=18.86, SD=6.00).
• Focuses on a specific population (children with Down syndrome aged 2y11m to 6y10m).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 16.8 KB, indicating limited scope.
