Background Detecting developmental delay in children is an ongoing world commitment, especially for those below three years. To accurately assess the development of children; a culturally appropriate screening tool must be used. Egypt lacks such tool and multiple studies have shown that western tools are not suitable in other cultures. Objectives To develop and validate an easy, rapid, culturally appropriate and applicable screening chart for early detection of developmental delay among Egyptian children from birth up to 30 months and develop a Z-score chart for motor and mental development follow up based on our Egyptian screening chart. Methods A cross sectional randomized study was carried out on 1503 Egyptian children of both genders aged from birth up to 30 months assumed to have normal development according to the inclusion and exclusion criteria. They were selected from vaccination centers and well-baby clinics. Developmental milestones from Baroda development screening test (BDST) were applied on them after items were translated and adapted to Egyptian culture. Egyptian children developmental milestones scores were analyzed and carefully prepared in tables and charts. A 97% pass level of developmental achievements represents the threshold below which children are considered delayed. A Z-score chart for motor and mental development follow up was designed by calculating each age group achievement. The developed Egyptian developmental screening chart (EDSC) was validated against Ages and Stages Questionnaires (ASQ-3) as a reference standard in another different sample of 337 children in different age groups. Results The developed EDSC is represented in a chart format with two curves 50% and 97% pass level. Children considered delayed when the score below 97% pass level. Results revealed a statistically significant difference between EDSC and BDST at 50% and 97% pass levels. A Z-score chart for motor and mental development follow up was designed by calculating each age group achievement. EDSC sensitivity and specificity were calculated 84.38 (95% CI [67.21%–94.72%]) and 98.36 (95% CI [96.22%–99.47%]) respectively with an overall test accuracy 97.03 (95% CI [94.61%–98.57%]) (p ≤ .001). Agreement between EDSC and ASQ-3 was high (kappa score was 0.827) with negative and positive agreement 98.36 and 84.38, respectively. Conclusions Extensive revision of the BDST was needed in order to create and validate a more culturally appropriate Egyptian screening chart. This is the first study to create and validate an Egyptian-specific screening tool, to be rapid and easy to use in Egypt for early detection of developmental delay and enabling early intervention practices. A Z-score curve is reliable for follow up motor and mental development by calculating each age group achievement.

Background: Detecting developmental delays in infants is an ongoing world commitment, especially for those below three years old. it provides appropriate services to them, early inspection enhances the communal quality of resolving difficult issues of this critical period of age. Thus, our main objective lies in developing a sufficient screening test for early evaluation of mental and motor development for infants.Methods: 54 items of motor and mental developmental milestones were adopted from the Baroda Screening Test. Then, researchers enrolled 1600 subjects based on certain inclusion and exclusion criteria. 97 pass level of developmental achievements resembles the threshold of which infants below which, infants are considered delayed.Results: The designed Egyptian Developmental Screening Tool (“EDST”) from birth up to 30 monthswith 50% and 97% pass level curves proves efficacy, reliability, cultural adaptability, and simplicity to use when compared with other peer screening tools. Results revealed a statistically significant difference between Egyptian and Baroda chart at 50% and 97% pass level. A z-score chart for motor and mental development follow up designed by calculating each age group.Conclusions: Developmental screening tests from birth up to 30 months proved consistent reliability and versatility to use in Egypt for early development delay detection. The wide variation of Egyptian infants 'developmental ages on both Egyptian and Baroda charts underpins the Egyptian chart to the Egyptian public. The z-score chart is a rapid and easy follow-up chart for Egyptian infants' development.
