Three hundred (300) youth from 4 different sites within the U.S will take part in the study. Youth will be randomly assigned to complete either the TeenCope or Managing Diabetes program right away, and will be given the opportunity to complete the alternate program after 12 months. Data on psychosocial and disease management parameters will be collected at baseline, 3, 6, 12 and 18 months through youth filling out online questionnaires (lasting approximately 30 minutes). Clinical outcome data (height, weight, HbA1c, episodes of hypoglycemia, DKA, and hospitalization) will be collected from the medical chart throughout the study, and parents will complete a demographic data form.
