Diagnostic Accuracy of the Government of India Mother and Child Protection Card for Developmental Screening of Indian Children Aged 2-36 Months: A Hospital-based Mixed Method Study

Background: Universal developmental screening is recommended at 9, 18, 24 and 36 months. The Government of India Mother and Child Protection (MCP) card is an immunization record that is used to monitor child development, and identify children requiring further evaluation. Objectives: To determine the diagnostic accuracy of the MCP card for developmental screening, and perform its item analysis. Study design: Mixed-method study (prospective study of diagnostic accuracy and qualitative study). Participants: Mother-child dyads of children between 2-36 months of age were recruited from the outpatient department or wards of a tertiary level children’s hospital from November, 2019 to October, 2021. Children with confirmed neurodevelopmental disorders/disability, and mothers with less than 6th standard education were excluded. Intervention: Each mother was given a MCP card, and taught how to mark the items. This was followed by the researcher’s evaluation (index tool). The reference tool was a comprehensive clinical assessment (CCA) by the researcher and an expert. The CCA included clinical examination of hearing, vision, and neurodevelopment; and psychometric assessment of development and adaptive function. Each mother underwent an in-depth interview. Overall and group wise psychometric properties of diagnostic accuracy were computed. The interview transcripts were analyzed thematically. Outcomes: The proportion of children with ‘fail’ and ‘delay’ by the evaluation of the researcher with the MCP card and the expert by the CCA, respectively. Results: The study population included 213 children (40.4% females). Fifty-two (24.4%) children were identified as ‘Fail’ by the MCP card and 43 (20.2%) as ‘delay’ by the expert’s CCA. The overall sensitivity and specificity was 83.7% (95% CI 69.3-93.2) and 90.6% (95% CI 85.2-94.5), respectively. Acceptable diagnostic accuracy was found in the age-group 7-9 months, 13-18 months, and 25-36 months. Conclusions: The MCP card may be used for developmental screening at 9, 18, and 36 months.
