Trivandrum Developmental Screening Chart.

Abstract

The Trivandrum Developmental Screening Chart (TDSC) was designed by selecting 17 test items from BSID (Baroda Norms). It was validated both at the hospital and community level against the standard DDST. TDSC had a sensitivity of 66.7% and specificity of 78.8%, which makes it an acceptable simple screening tool even for the community level worker.
