Timely screening and surveillance of children for developmental delay and social-emotional learning difficulties are essential in Low- and Middle-Income Countries like India. Screening measures like the Parents' Evaluation of Developmental Status (PEDS) and Strength and Difficulties Questionnaire (SDQ) are considered suitable for India due to their low cost, easy accessibility, and no training requirement for administration. However, India lacks validated screening measures, and the PEDS and SDQ have yet to be validated for children in India. The study aimed to translate the PEDS and SDQ from English to Hindi and psychometrically evaluate the same measures on children aged 4-8 years in India. The original PEDS and SDQ forms and their translations were pilot tested on 55 participants and evaluated using data from 407 children with typical development (TD) and 59 children with developmental disability (DD). Parents and teachers reported no meaningful discrepancy between the original and translated (Hindi) questionnaires. Internal consistency for the PEDS was acceptable, but unacceptable for most subscales on the SDQ, for both TD and DD samples. Test-retest reliability was poor for the PEDS but adequate for the SDQ. Results from known-group validity testing showed that the PEDS scores could be used to distinguish between the TD and DD samples. The results from this study provide further support for the use of the PEDS and SDQ in developing countries like India.
