• Heart Diseases
• Obesity
• Diabetes Mellitus, Non-insulin Dependent
• Hypertension

Interventions

BEHAVIORAL

Personal contact (PC)

This arm uses brief, individual contacts on a monthly basis which emphasize core elements of weight maintenance. Monthly contacts with an interventionist occur for 30 months after the end of Phase I. Face-to-face contacts occur approximately every four months (e.g., three annually), with telephone contacts occurring every month between FTF contacts.

BEHAVIORAL

Interactive technology (IT)

The website utilizes collaborative goal setting and problem-solving strategies to identify contingent action plans for perceived obstacles to success. In order to tailor the intervention to the needs of the participant, the action plan can be updated anytime and as frequently as desired by the individual. Participants are encouraged to input data on weight, food records, physical activity, and goals on a weekly basis. Participants are not restricted to logging on to the website only once a week. Rather, participants have the option of logging on to the website to enter data, communicate with other participants, or to seek other information, as frequently as they wish.
