Validation of the Hindi version of Trivandrum Development Screening Chart (TDSC) as a Developmental Screening Tool in Children aged 1–30 Months
摘要
To determine the diagnostic accuracy of Hindi version of Trivandrum Development Screening Chart (TDSC) for developmental screening of children aged 1 – 30 months.
MethodsChildren 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).
ResultsThe 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).
ConclusionThe Hindi version of TDSC had acceptable psychometric properties and excellent test–retest and inter-rater reliability.
