Official title

Developmental Influences on Management of Type I Diabetes

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This 1-year study will explore the influences of family and peers on how diabetic adolescents manage their disease, focusing on adolescent developmental transitions. The management of diabetes is a complex process involving daily self-care activities, problem-solving, and decision-making. It is particularly challenging during adolescence when youth are experiencing physiological, social and psychological changes, and coming under increasing peer influence and decreasing parental supervision. Although it is expected that the responsibility for diabetes management will gradually shift from the parent to the child during adolescence, research indicates that many children may be given responsibility for managing their illness too early, without adequate parental monitoring. Specifically, this study will examine the following issues: * The relationship of peers, parents and school support to successful diabetes management; * The influence of the adolescent's self-image and personal goals on diabetes management; * The influence of the adolescent's and parents' attitudes, capability and environment on the balance of responsibility for diabetes management. Children between 10 and 16 years of age receiving treatment for diabetes type 1 at Georgetown University Medical Center's pediatric diabetes clinic may be eligible for this study. The children must have been diagnosed with diabetes at least 1 year before entering the study and must require insulin treatment. One parent of each child will also participate in the study. Children and their parents will complete the following procedures: Home Interviews: Parents and children will complete two at-home face-to-face interviews 6 months apart. At each interview, children will answer questions about their responsibility for and adherence to their diabetes management, treatment outcome expectations, optimism, self-esteem, self-consciousness, personal goals, social support, perceived barriers to diabetes management, family routine and family conflict, their parents' involvement in their diabetes management, and parenting style. Parents will evaluate their child's ability to manage his or her diabetes, level of maturity, self-esteem, and transition of responsibility; their family routine and family conflict, parent-child communication, their parenting goals, and their involvement in and responsibility for their child's diabetes management. Three days after the 6-month interview, a randomly selected group of parents and children will complete a brief, additional telephone interview covering some of the same issues. Telephone Interview: At 12 months, parents and children will complete a telephone interview that will include questions about adherence to diabetes management and the responsibility of parents and children for diabetes management.
