This study investigated the relationships of healthy children with their handicapped siblings and analyzed their acceptance of the siblings. The study was conducted in 16 different special education and rehabilitation centers in Ankara. Two hundred twenty-eight healthy children between the ages of 10 to 17 years voluntarily participated in the investigation. All participating children had siblings diagnosed with one of the six disabilities: Learning disability (LD), mental retardation (MR), cerebral palsy (CP), mental-motor retardation (MMR), Down syndrome (DS), or autism (A). The attitudes of the healthy children towards their handicapped siblings (EKYTO) and towards other handicapped people (EBYTO) were studied. Results show that healthy children display positive attitudes towards their own handicapped siblings whereas less positive attitudes towards other handicapped people. The investigation takes into consideration diagnosis and degree of the handicap. In general, it is observed that the healthy children's attitudes towards their handicapped sibling are clearly changing according to diagnosis and level of handicap whereas the same factors do not make any difference in terms of attitudes towards other handicapped people.
