Mutual support groups whose members are individuals who have been involved in physical or emotional abuse by a spouse or other partner. The groups meet in-person, by telephone or via the Internet; provide emotional support, information and resources for those who participate; and may be structured for victims of domestic violence, those responsible for battering them, or for adults or adolescents who as children were traumatized by witnessing violence in their homes.

Mutual support groups whose members are family, friends, significant others, non-familial caregivers or attendants who are caring for someone who has a temporary, chronic, life-threatening or terminal illness or disability or who is elderly and increasingly unable to provide for his or her own care. The groups meet in-person, by telephone or via the Internet; and provide emotional support, information and resources to help participants ensure their own well-being while remaining involved in the intense care of a loved one. Also included are care receiver support groups that help people who have a caregiver cope with the fact that they require care. Care receiver support groups are often offered in conjunction with caregiver support groups and are structured to allow care receivers to participate in their own group while their caregiver attends another.

Individuals who are generally between the ages of 18 and 25 depending on the ages that specific programs use for qualification.

Family members, friends, neighbors and others who assume responsibility for attending to the daily needs of individuals who are temporarily or permanently unable to care for themselves due to general frailty; illnesses, injuries or progressively debilitating conditions such as Alzheimer's disease or mental illness; or other incapacitating problems without compensation. Some, but not all, states have programs that help people pay for the caregiver of their choice, and in certain circumstances that can be a family member. Most of these programs have income and other eligibility requirements that the care recipient must meet, and strict rules often apply as to who can be paid for the caregiving. Benefits may also be available for veterans and their families through the Veteran's Administration.

Adult women who have been subjected to a persistent pattern of physical, sexual and/or emotional abuse and intimidation by their husbands or intimate partners.

Adults who have survived acts of rape, forced oral copulation, sodomy or other forms of sexual assault by their spouses or intimate partners.
