The problem
Intervention: Home cognitive stimulation through learning materials, modeling, and variety of activities
Who it was tested with: 29 preschool-age children (M age = 4.4 years) with sickle cell disease.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"Researchers and caregivers completed the Home Observation for Measurement of the Environment (HOME), an in-home measure of cognitive stimulation. Linear regression was used to examine the relationship between each of the HOME subscales and cognitive and academic measures while controlling for genotype." The study associated home environmental factors with cognitive outcomes in children with sickle cell disease, but the observational design cannot determine whether home stimulation causes improved cognitive development or if the relationship is bidirectional or confounded.
Cross-sectional design prevents causal inference; small sample size (n=29); no comparison group; no information on effect sizes or statistical significance levels provided
