Programs that link individuals who have a particular type of illness with others having the same illness for the purpose of information sharing and support. Included are networking programs that make a portal or other technology available that encourages people living with mental health conditions, disabilities, physical illnesses or other problems to tell their stories about the challenges they are facing and the steps they have taken to cope with their situation. Sharing one's story can help in the person's own recovery but can also be an inspiration and source of encouragement for others in a similar situation.

Mutual support groups that schedule virtual "meetings" via the Internet. Included are groups using video conferencing platforms like Zoom or Google Meet (which emulate a person-to-person meeting using real-time video and audio streaming), e-mail listserv groups (which distribute posted messages to participants via e-mail), bulletin/message boards (whose postings are restricted to people who register), newsgroups (whose postings are unrestricted and open) and chat groups (which permit real time discussion) that are devoted to providing support for participants around a particular issue. Internet support groups are generally available around the clock; and are convenient for people with limited mobility, serious health issues or transportation problems, who don't have time for face-to-face meetings, or who simply wish to maintain their privacy and remain anonymous. They may be the only option for individuals with rare disorders or other unusual problems who are unlikely to find enough people in their local area to form a support group. Internet support groups may be monitored by professionals, but most are not.

Mutual support groups whose members are people who have a disability, illness or other health condition, their families and friends. The groups meet in-person, by telephone or via the Internet; and provide an opportunity for participants to share information, resources, practical tips for daily living and encouragement about issues related to the disability or health problem.
