Abstract

The accurate early identification of developmental delay in young children is important. The aim of this study was to highlight and propose a solution to problems associated with scoring a UK developmental screening tool known as the Schedule of Growing Skills II. Potential problems associated with the sensitivity of this screening tool were identified. As a possible solution to this problem, an alternative scoring method was developed to yield a developmental quotient. A pilot investigation of the new scoring method was conducted through comparisons with the Griffiths Mental Development Scales. Forty-three children aged 0 - 5 years were recruited and administered both developmental assessments. Results from both assessments were compared to examine validity. Both the new and published scoring methods showed good concurrent validity, however the new scoring method demonstrated better criterion-related validity in terms of higher sensitivity, comparable specificity, generally higher over-referrals, and lower under-referrals. The Schedule of Growing Skills II could be a valid, cost-effective way of screening for developmental delay in young children using this new, more sensitive scoring method.
