Abstract

Objectives: The goal of the present study was preparing and determining the validity and reliability of “Newsha Developmental Scale” as an integrated test of cognitive, social communication and motor skills of Persian speaking children. Method: The first version of Newsha scale was prepared in three developmental milestones of “cognition”, “social communication”, and “motor” in 13 age groups from birth to 72 months. After a pilot study, the test was conducted on 593 normal children of both sexes in nurseries of

Tehran province. The psychometric values were determined using test-retest reliability, inter-rater reliability, content validity and construct validity. Results: A correlation of more than 92% was found in both kinds of reliabilities (p<0.001). Construct validity exhibited the effect of age on test results in 91 percent of the instances. Difference between boys and girls was shown in only 4 items among all the 275 items of the scale (p<0.02). Conclusion: The “Newsha Scale” is an integrated and a comprehensive scale for evaluating development process and identifying any delay in developmental abilities in Persian speaking children from birth to 6 years of age, and has an appropriate reliability and validity.
