The objective is to determine the effects that are found in the siblings of intellectually disabled children. Previous studies, have concluded that there are certain effects that intellectually disabled children have on their siblings. The effects that are considered in the paper are stress; anxiety levels, internalizing and externalizing behaviors; how they deal with problems, and lastly self-perception; whether they are mentally stable and confident. Negative effects are going to be the focus of the study, however, there are certain positive effects that are exposed. Levels of warmth and affection are higher when a child has a sibling with a disability. There were various forms of instruments used through the different articles: Personal Information Questionnaire , the Rosenberg Self- Esteem Scale and the Trait Anxiety Scales; Wechsler Intelligence Scale for Children-4^th Edition, the Vineland Adaptive Behavior Scales, the Sibling Relationship Questionnaire, the Social Skills Rating System-Secondary Level, and the Achenbach Child Behavior Checklist; Semantic Differentials. An interview was also conducted on a single person, who proved the hypothesis of all the articles.
