Behaviors and Attitudes of Normally Developing Children toward Their Intellectually Disabled Siblings

This study investigated behaviors of children who have normal development toward their siblings with intellectual disabilities. 9- to 17-year-old normally developing siblings (55 girls, 39 boys) of 94, 5- to 15-year-old mentally disabled children (51 girls, 43 boys) who were attending a special education and rehabilitation center were enrolled in the study. Data were gathered by using a general information form and the Schaeffer Sibling Behavior Rating Scale. Age of the disabled child did not have a significant effect on siblings' behaviors, while knowledge of family about the diagnosis and educational status of their child with intellectual disabilities affected sibling behaviors.
