Insights
The Child Development Evaluation Test (EDI) group 15 effectively screens children aged 60-71 months for developmental delays. This validated tool shows high sensitivity and negative predictive value, enabling early intervention.
Area of Science:
- Pediatric Development
- Screening Tools
- Child Psychology
Background:
- Early childhood is crucial for development.
- The Child Development Evaluation Test (EDI) is a validated screening tool in Mexico for children aged 1 month to 4 years and 11 months.
Purpose of the Study:
- To validate group 15 of the EDI test for children aged 60-71 months.
- Compare sensitivity, specificity, PPV, and NPV against the BDI-2 Spanish version as the gold standard.
Main Methods:
- Cross-sectional analytic study.
- 46 children aged 60-71 months evaluated with EDI group 15 and BDI-2.
- Non-probabilistic convenience sampling at Hospital Infantil de México Federico Gómez.
Main Results:
- Sensitivity: 93.8% (95% CI: 81.8%-100%).
- Specificity: 73.3% (95% CI: 57.5%-89.1%).
- PPV: 65.2%, NPV: 95.5%.
Conclusions:
- Group 15 of the EDI test demonstrates high sensitivity and NPV in this age group.
- Facilitates early detection and intervention for previously uncovered developmental issues.
- This study is the first to validate this age range for the EDI.
Background:
Early childhood is a critical period for child development. The Child Development Evaluation Test (EDI in Spanish), developed and validated in Mexico, is a screening tool for developmental problems in children from 1 month to 4 years and 11 months.
Objective:
To validate group 15 of the EDI test for children aged 60-71 months, comparing sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) using the Battelle Developmental Inventory 2nd edition (BDI-2) in Spanish as the gold standard.
Methods:
A cross-sectional analytic study with 46 children aged 60-71 months was conducted at the Hospital Infantil de México Federico Gómez. Children were evaluated using group 15 of the EDI test and BDI-2. The sample was non-probabilistic by convenience. Diagnostic metrics and comparisons were performed globally and in the developmental domain.
Results:
The sensitivity and specificity of group 15 for the EDI test were 93.8% (95% confidence interval [CI]: 81.8%-100%) and 73.3% (95%CI: 57.5%-89.1%), respectively. The PPV was 65.2%, and the NPV 95.5%. The highest percentage of false negatives was in the cognitive domain, followed by the adaptive domain.
Conclusion:
In this first study, group 15 of the EDI test shows high sensitivity and NPV, allowing early detection in an age group previously not covered, thus facilitating interventions in this group.
