Rapid advances in technology have made the internet a compelling tool to reach out to youth and significantly broaden the application of CST programs. Investigators at Yale (scientists, NPs, clinical psychologists) have teamed with web specialists (computer programmers, web designers, graphic artists, and illustrators) and youth with T1D and their parents to adapt the successful CST program for use on the internet. In this trial, internet-based CST (TeenCope) will be evaluated by comparing it to an internet-based education program for managing diabetes (Managing Diabetes).
