CHESS Participants in Group 1 and Group 3 who receive the CHESS internet-based program will have access to information, social support, and skill-building services. The CHESS system will keep a record of how often and for how long each part of CHESS is used. Information will also be gathered about anything you communicate in the CHESS interactions. This information will be used to figure out which parts of CHESS may be most useful. You will be provided a free 1-800 phone number for computer support if you need any help.
