The purpose of this study is to determine that continuous glucose monitoring systems (CGMS)
with intensive real time feedback about diabetes management from medical staff to the patient
will affect motivation and/or behavior, in adolescents with poorly controlled type 1
diabetes. The investigators hypothesize that short-term CGMS use with feedback (and/or lack
thereof) and patients' sense of self-efficacy will influence their stage of change and
potentially glucose levels.
