As new treatments allow chronically ill children to live longer, the relationship between the child's psychological state and his physical condition becomes paramount. Diabetics (N=42) between the ages of 10 and 21 answered questions about their disease. While most respondents did not feel that diabetes had affected relationships with peers, siblings, parents, or school performance, a significant minority believed that diabetes had important effects in at least one area. The Diabetes Opinion Survey, developed to measure a patient's feelings of stigmatization and to assess the relationship of this perception to other patient attitudes about diabetes, was completed by 150 diabetic children. Responses revealed that children who felt stigmatized by diabetes believed that their disease had affected family life, used their diabetes to manipulate others, and felt that other persons, not they, should manage their diabetes. Data from the Parents' Diabetes Opinion Survey revealed that the mothers of "stigmatized" children also believed that diabetes had stigmatized their children, affected family life, and was used by their children to manipulate others. Results of both surveys suggest that a substantial minority of diabetic children feel stigmatized by this disease. (NRB)
