This study aimed to extract the psychometric properties of a Jordanian version of the Parents Evaluation of Developmental Status: Developmental Milestones (PEDS:DM) to present a psycho-metrically reliable Arabic scale that benefits the Jordanian context as an effective childhood intervention scale. The validity of the scale was achieved in three ways: Face, construct, and concurrent validity. Face validity was accomplished through the translation steps. As for construct validity; the internal consistency of the translated version was checked. The correlation between the items and sub-scales was high, which indicated high construct validity. Lastly, the concurrent validity was obtained by calculating the Pearson correlation between the Arabic version of the PEDS:DM and the Preschool and Kindergarten Children's Performance scale (PKCPS). The significance of correlated validity for the domains of the scale was as follows: Cognitive (0.79), physical (0.83), social (0.82), and total score (0.84). The indicators of reliability were extracted in two ways: The scale's test-retest reliability, and the internal consistency reliability. The values of the coefficients of reliability for the test-retest ranged between (0.88-0.92) for the different domains, and (0.91) for the total mark. The coefficients of reliability for internal consistency using Cronbach's Alpha had values between (0.82-0.91) for the different domains, and (0.89) for the total mark. Consequently, the Jordanian version of the PEDS:DM is psycho-metrically valid and reliable. As a result, this scale is one of the first instruments that can be implemented safely in the Jordanian context to achieve early detection of any developmental delays in children.
