Concurrent validity of the gross motor component of ages and stages questionnaire-3 with the motor scales of Developmental Assessment Scales for Indian Infants (DASII) in risk infants < 6 Months

Abstract

Objective: Global developmental delay is the term used when a child lags or has a delay in all the domains of development. Early detection of this delay is a necessity to commence with early intervention. This study aimed to determine the concurrent validity of gross motor component of Ages and Stages Questionnaire-3 (ASQ-3) with the motor scales of Developmental Assessment Scales for Indian Infants (DASII) in risk infants Materials and Methods: This cross-sectional study included risk infants in the age group of 1–6 months (n = 97). They were assessed using the age-appropriate ASQ-3. The parents/caregivers of the children filled in the child-appropriate responses. The children were then assessed using the DASII. The scores of ASQ-3 and DASII were recorded as per the instructions in their respective manuals. Results: One hundred and fifty infants were screened for eligibility, of which only 97 were eligible according to the study criteria. Fifty-four children failed on the gross motor domain of ASQ-3, whereas sixty children failed on the motor scales of DASII. The overall sensitivity and specificity of the ASQ-3 were found to be 73.80% and 89.83%, respectively. The sensitivity of the ASQ-3 at 2 months was 75% and 66.67% at 4 and 6 months. The specificity of the ASQ-3 at 2, 4, and 6 months was 88%, 90%, and 93.33%, respectively. Conclusion: ASQ-3 has strong characteristics to detect motor developmental delay in infants at risk for developmental delay.
