Abstract EN

Aims: Several studies have been conducted on the Stanford- Binet scale, the fourth image, to ensure the validity of its application to the Egyptian environment, and the current research deals with modifications that would increase that validity, especially when applying the scale to disabled children with Down syndrome.

The research included making adjustments in the shape and size of some tools such as the child’s picture, the size of the cubes, the shape board, the memory of bead,… etc.

Sample: The scale was applied before and after the modification on a sample of mentally handicapped children with schizophrenia, and normal children 80 children between the ages of 5 and 12 years with an average of 9.7, and standard deviation of 1.7.

They are divided into two groups: mentally handicapped children with Down syndrome 40, and normal children 40.

Tools: The research used a scale between the traditional fourth image and the modified fourth image, and the validity of the discrimination between the contrasting groups was calculated using a t- test to reveal the differences in the mean scores of intelligence between the group of mentally handicapped children and normal children, and it was a significant of 0.001; The internal consistency was validated by using the Pearson correlation coefficient to determine the relationship between the total score and the sub- scores of the scale, which was a significant of 0.05.

Cronbach's alpha stability was 0.096 and it was high, and factor analysis was used to detect the factors constituting the cognitive structure of the mental abilities of mentally handicapped children with Down syndrome and normal children.

In children with Down syndrome, four factors on the modified scale instead of two factors on the traditional scale, and in normal children, it reached six factors instead of five.
