The interpretation of Bayley scores are based on norms established for children in the United States (US), which is based on a national standardized sample of 1700 children between 1 and 42 months of age, and divided into 17 age groups.ĭespite its wide use and well-established psychometric properties, the Bayley III scale has not been validated in Sri Lanka. The Bayley III scales can be used to assess infant and toddler development across five key developmental domains - cognition, language, social-emotional, motor and adaptive behaviour. The Bayley scales have been used in various countries such as Brazil, Taiwan and Australia currently it is in its third edition. It has been shown to be a valid diagnostic tool for identifying children with developmental delays at an early age and is widely used in clinical settings due to its solid theoretical background and robust psychometric properties.
The Bayley Scales of infant development is a commonly used psychometric tool for assessing the development of children between 1 to 42 months of age. A reliable and valid tool for diagnosing developmental delays in very young children would enable the early identification of children with impairments.
Furthermore, it is only a screening tool and is not useful for diagnostic purposes. The Denver II has been shown to have limited specificity and high over-referral rates and has been considered as test of questionable value in terms of screening for developmental delay. Currently, a culturally validated Denver Development Screening Test (DDST) is being used in the Maternal and Child Health programme of the Ministry of Health, Sri Lanka to screen child development. The prevalence of developmental disabilities in Sri Lanka has been estimated to be 12 – 29% and the majority of children with clinically identifiable developmental problems in Sri Lanka are referred to child mental health services relatively late, generally when they are over 5 years of age, due to low rates of early recognition. Early intervention in children at risk for developmental delays can lead to better outcomes and improved child well-being.
