Abstract

This chapter aimed at identifying the psychometric properties of Vanderbilt’s scale for detecting people who suffer from attention deficit hyperactivity disorder (ADHD) in the cycle one schools in Al Batinah North Governorate in Oman based on the Rasch Rating Scale Model. The scale in its final version consisted of 43 items where items from 1 to 3 followed the quadruple Likert’s scale while items 36 to 43 followed quintuple Likert scale. The scale was applied to a sample consisting of 513 students, including 211 students with attention deficit hyperactivity disorder while 302 normal students. The research used a descriptive analytical approach, and Winsteps software was used to analyze data obtained from Vanderbilt’s scale and interpret them. The results showed that there is a match between the items of Vanderbilt’s scale and the rating scale model and the one-dimensional assumption was also achieved. Moreover, the value of the reliability coefficient for the items reached 1, and the separation index for the items reached 19.16. Furthermore, the reliability coefficient for individuals was 0.96, and the sep aration index for individuals was 5.16. This indicates that the scale has high reliability. Besides, the findings of the item order revealed that the values of Vanderbilt’s scale item difficulty estimates ranged from 2.22 logit to −2.68. The standard error values ranged from 0.09 to 0.05 which could be considered to be very small. Such small values indicate the accuracy and reliability of the scale. The results of the efficiency of the response categories also showed that the categories are gradual in terms of difficulty and fit the Rasch Rating Scale Model. Based on the study’s out comes, it is recommended that Vanderbilt’s scale be utilized to screen the children with ADHD.
