Insights
The Communication and Symbolic Behaviour Scales Developmental Profile-Infant Toddler Checklist (CSBS-ITC) accurately screens for communication delays in infants and toddlers. This tool is effective for identifying at-risk children needing further assessment.
Area of Science:
- Developmental Pediatrics
- Communication Sciences
- Early Childhood Assessment
Background:
- Early identification of communication delay is crucial for timely intervention.
- The Communication and Symbolic Behaviour Scales Developmental Profile-Infant Toddler Checklist (CSBS-ITC) is a potential screening tool for this age group.
Purpose of the Study:
- To evaluate the diagnostic accuracy of the CSBS-ITC for screening communication delays in children aged 6-24 months.
- To determine the sensitivity, specificity, PPV, and NPV of the CSBS-ITC.
Main Methods:
- A hospital-based observational cross-sectional study involving 200 children aged 6-24 months.
- Children were assessed using the CSBS-ITC and the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III).
- Risk stratification based on perinatal and neurological factors was performed.
Main Results:
- The CSBS-ITC identified communication concerns in 69% of children.
- A high sensitivity (94%) and specificity (82%) were observed for the CSBS-ITC.
- Positive predictive value was 87% and negative predictive value was 80%.
Conclusions:
- The CSBS-ITC demonstrates good screening accuracy for communication delay in young children.
- The tool is valuable for screening high-risk children aged 6-24 months.
- CSBS-ITC aids in identifying children who may benefit from further developmental assessment.
Objective:
To assess the accuracy of the Communication and Symbolic Behaviour Scales Developmental Profile-Infant Toddler Checklist (CSBS-ITC) for screening communication delay in children aged 6-24 months.
Method:
This hospital-based observational cross-sectional study included 200 children aged 6-24 months of either sex attending the child development clinic. Participants were categorized into high- and low-risk groups based on perinatal and neurological risk factors. The CSBS-ITC was administered to parents, followed by a standardized developmental assessment using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of CSBS-ITC were calculated.
Results:
Communication concerns were identified in 69% of children using the CSBS-ITC, and among these, 65% was confirmed to have language delays on the BSID-III assessment. CSBS-ITC demonstrated a high sensitivity (94%) and specificity (82%), with a positive predictive value of 87% and a negative predictive value of 80%.
Conclusion:
CSBS-ITC is a useful tool for screening communication delay in high-risk children aged 6-24 months, and the tool exhibits good screening accuracy.
