During an 8-12 month period, the GSD-Y group will complete 8 outpatient GSD-Y visits, and the control group will completes an equal number of standard visits. The primary outcome is HbA1c. Secondary outcomes include the following: number of self-monitored blood glucose values and levels of autonomous motivation, involvement and autonomy support from parents, autonomy support from HCPs, perceived competence in managing diabetes, well-being, and diabetes-related problems. Primary and secondary outcomes will be evaluated within and between groups by comparing data from baseline, after completion of the visits, and again after a 6-month follow-up. To illustrate how GSD-Y influences glycaemic control and the development of life skills, 10-12 GSD-Y visits will be recorded during the intervention and analysed qualitatively together with individual interviews carried out after follow-up.This study will provide evidence of the effectiveness of using a GSD-Y intervention with three parties on HbA1c and life skills and the feasibility of integrating the intervention into routine outpatient clinic visits.Danish Data Association ref nr. 2008-41-2322ISRCTN54243636Type 1 diabetes in adolescents is a challenge for the teenagers, their parents and the diabetes health care providers (HCPs) [1]. Despite new medical treatment modalities, the prognosis for childhood-onset type 1 diabetes remains poor [2,3]. The number of life years lost remains unchanged over the last four decades at approximately 17 years for a child diagnosed with type 1 diabetes at the age of 10 years [4]. Keeping blood glucose levels as close to normal as possible from as early in the disease as possible is known to prevent or postpone late di %U http://www.biomedcentral.com/1471-2431/11/55
