The purpose of this study is to utilize a group therapy adjustment and coping program at the Children's Hospital of Wisconsin with patients who have Type 1 Diabetes Mellitus (T1DM) and their parents within a "typical" clinical condition of patients who have been referred for outpatient therapy services. To extend the previous literature on these types of peer and family-based groups to include survey data as well as provider ratings, medical data, and add retrospective and prospective data from baseline enrollment. To aid in establishing this group therapy methodology as a "promising" evidence-based intervention within a population of youths with T1DM and their families. The specific aim of this project is to enroll patients and their families into either a treatment group or a wait list control group to receive the group intervention to determine the impact of this peer and family-based group on improving adjustment, coping, and functioning within diabetes.
