Insights
The Hindi version of the Trivandrum Development Screening Chart (TDSC) accurately screens for developmental delays in children aged 1-30 months. This validated tool demonstrates good reliability for early childhood development assessment.
Area of Science:
- Pediatrics
- Developmental Psychology
- Public Health
Background:
- Early detection of developmental delays is crucial for timely intervention.
- Standardized screening tools are essential for accurate developmental assessment in diverse populations.
- The Trivandrum Development Screening Chart (TDSC) is a widely used tool, but its Hindi version required validation.
Purpose of the Study:
- To evaluate the diagnostic accuracy of the Hindi version of the Trivandrum Development Screening Chart (TDSC).
- To assess the reliability and validity of the Hindi TDSC for developmental screening in children aged 1 to 30 months.
Main Methods:
- A prospective study involving 224 children aged 1-30 months recruited from a pediatrics department.
- The Hindi TDSC was administered by a trained researcher, with results categorized as 'Pass' or 'Fail'.
- The Developmental Assessment Scale for Indian Infants (DASII) served as the reference standard for diagnosis.
Main Results:
- The Hindi TDSC showed a sensitivity of 92.3% and specificity of 83.6% for detecting 'Developmental delay'.
- For 'Any delay', sensitivity was 70.5% and specificity was 90.2%.
- Excellent test-retest and inter-observer reliability was confirmed (Cohen's Kappa 0.720).
Conclusions:
- The Hindi version of the TDSC possesses acceptable psychometric properties for developmental screening.
- The tool demonstrated excellent test-retest and inter-rater reliability, making it suitable for clinical use.
- This validated Hindi TDSC can aid in the early identification of developmental concerns in Indian children.
Objective:
To determine the diagnostic accuracy of Hindi version of Trivandrum Development Screening Chart (TDSC) for developmental screening of children aged 1 - 30 months.
Methods:
Children aged 1 to 30 months who were accompanied by their mothers were recruited from the pediatrics department. Children with acute illnesses which could interfere with developmental assessment, unavailable birth records and from families unable to understand Hindi language were excluded. After translation into Hindi, TDSC was piloted initially on 25 children and later on 224 participants by a researcher who was trained in application and interpretation of TDSC. The results were interpreted as item 'Pass' or 'Fail'; 'TDSC delay' or screen positive was considered even with one item fail. Subsequently, Developmental Assessment Scale for Indian Infants (DASII) was administered to all by a trained clinical psychologist as reference tool and the final diagnosis was made based on developmental quotient (DQ) as: 'any delay' (DQ < 85), 'developmental delay' (DQ < 70), 'borderline delay' (DQ 71-84) or 'no delay' (DQ ≥ 85).
Results:
The sensitivity and specificity of Hindi version of TDSC for 'Developmental delay' and for 'Any delay' was 92.3% and 83.6%, and 70.5% and 90.2%, respectively. The test-retest and inter-observer validity was good (Cohen's Kappa 0.720).
Conclusion:
The Hindi version of TDSC had acceptable psychometric properties and excellent test-retest and inter-rater reliability. Trial registration CTRI/2021/06/033957.
