Introduction: Since the incorporation of women into the world of work, together with the progressive ageing of the population and the increase of chronic diseases, there is an alteration in the role of the caregiver, due to the physical, work and family burden it bears, emotional conflicts and with other family members. Mutual aid can be an effective alternative to promoting the well-being of caregivers, as well as their families and dependents. Objective: To know the characteristics of self-help groups for family caregivers and their influence on caregivers, the dependent and family health. Methodology: Systematic review. The search strategy included the Pubmed, Scopus, Psycinfo, Eric, Cochrane plus and CSIC databases; selecting scientific articles in either Spanish, Catalan, English, Portuguese or French, for the last 10 years. Results: 12 articles related to the study topic were selected. All studies show that participation in these groups can improve the physical-psychological well-being, the health of caregivers and, at the same time, reinforce their sense of social support, although there is a lack of studies in our environment, with a size higher quality sample. Conclusions: Caregivers benefit from participating in self-help groups. Therefore, they should become a routine component of the family caregiver.
