Abstract
This article presents results of a study examining the psychological adjustment of well child siblings living in the same household as siblings with diabetes. A sample of 28 well siblings between the ages of eight and 12 were studied. Psychological adjustment was assessed by measuring self-concept, behavioral difficulties and competence, anxiety, and depression on standardized tests. A semistructured interview reported data gathered on the well siblings' emotional feelings and their communication patterns. The well siblings demonstrated significant internal psychological stressors and maintained high levels of behavioral competence. The internal stressors originated from anxiety and low self-concept. Recommendations based on the findings are offered to professionals who work with children with diabetes and their families.
