Abstract
Background: Globally there were 249 million children under the age of five years who were at risk of poor development in 2010. Ethiopia is one of the top ten countries with children at high risk of developmental problems. To assess and monitor the developmental status of children, there is a need for reliable and valid measures. The Bayley Scales of Infant and toddler Development III (BSID III) tool is a rigorous measure of child development that has been widely used across different cultural settings. However, the BSID III is resource intensive necessitating the need for simpler tool for large-scale use. Objective: To evaluate the concurrent validity of Denver II in assessing the development of children aged 24 to 36 months who lived in the Butajira Health and Demographic Surveillance System (HDSS), using the BSID III as a gold standard. Methods: The study design was a community-based, cross-sectional concurrent validation design. The study was conducted in the Butajira HDSS, Southern Nations Nationalities and Peoples’ Regional state on children aged 24-36months who were selected randomly from a sampling frame obtained from the HDSS. Data were collected from March- April 2017. The Denver II and BSID III were administered by independent groups of trained and reliable data collectors who were masked to the status on the other measure. Order of administration was randomized. STATA version 14 was used for analysis. The sensitivity, specificity, positive predictive value and negative predictive value of the Denver II against the BSID III were calculated. Result: A total of 121 children age 24-36 months with their caregivers participated in this study. The response rate was 91.6%. Sixty (49.6%) of the children were male. One hundred seventeen (96.7%) children lived with their biological parents, 3 (2.5%) lived with relatives and 1 (0.8%) lived with unrelated care takers. Using BSID III as the gold standard, the sensitivity of Denver II was 99% for fine motor, 80% for gross motor and 79% for language subscales. The specificity was 12% for fine motor, 11% for gross motor and 39% for language subscales. Total scores on the Denver II had a correlation coefficient of 0.26 for gross motor, 0.42 for fine motors and 0.57 for language subscales with the corresponding BSID III subscales. Conclusion and recommendation: It is important to be able to detect developmental delays in a timely manner so that early intervention can support the child to fulfill their developmental potential. In this rural Ethiopian setting, the Denver II showed potential as a brief screen for developmental delay, with high sensitivity; however, the low specificity means that there will be many false positives. This may limit application of the tool in routine settings. Further studies of adaptation and of short child development measurements are needed.
