Abstract :
In this research, the "diagnostic validity of the working memory scale of the fifth version of the Wechsler IQ scale in preschool children with attention deficit disorder" has been discussed. The main question of the research is whether the fifth version of the Wechsler children's intelligence scale has diagnostic validity in preschool children with attention deficit disorder. The current research method is in the field of psychometric researchs, which is a subset of the methodological research method. The research population consists of all preschool children with attention deficit disorder, which were selected as the sample size using the available targeted sampling method of 120 preschool children with attention deficit disorder. The measurement Instrument in this research is the fifth version of Wechsler's intelligence scale for children, which has good validity and reliability. The statistical model used in this research to determine the diagnostic validity is the scatterplot method (Davis method) and the confidence interval method. Finally, the findings of the research showed that using the scatterplot method in the fifth edition of the "number capacity", "image capacity" and "number-letter sequence" tests have diagnostic validity. Also, by emphasizing the confidence interval method, working memory scale in diagnosing preschool children with attention deficit disorder has diagnostic validity and can distinguish preschool children with attention deficit disorder from other students.
