Abstract
Objective
To develop and validate a simple screening tool for identifying developmental delay among children of 0–6 y of age in the community.
Methods
The 51-items of Trivandrum Development Screening Chart for children of 0–6 y [TDSC (0–6 y)], were carefully prepared from the norms in various existing developmental charts/scales, by experts keeping in mind the face validity and content validity. The criterion validity was assessed in a community sample of 1,183 children of 0–6 y with a mean age of 35.38 mo (SD of 19.25) including 597 (50.46 %) boys and 586 (49.54 %) girls. TDSC (0–6 y) was validated against Denver Developmental Screening Test (DDST) as the ‘Reference Standard’.
Results
When one item delay in TDSC (0–6 y) was considered as ‘TDSC delay’ (test positive), the sensitivity and specificity of TDSC (0–6 y) was found to be 84.62 % (95 % CI: 71.92–93.12) and 90.8 % (95 % CI: 88.97–92.43) respectively with a Negative Predictive Value of 99.23 % (95 % CI: 98.48–99.67) and LR (negative) of 0.17(95 % CI: 0.09–0.32). The test-retest and inter-rater reliability [an interclass correlation (ICC) of 0.77 for test-retest and ICC of 0.97 for inter-rater] were good and acceptable.
Conclusions
TDSC (0–6 y) is a simple, reliable and valid screening tool for use in the community to identify children between 0 and 6 y with developmental delay, enabling early intervention practices.
