The literature review defines a foster parent, foster care and forms of foster care for elderly people in the Republic of Croatia, as well as foster care for elderly persons with mental disorders. This literature review also presents an example of the experience of foster parents of elderly people with mental disorders. In order to improve foster care for elderly people with mental disorders, the aim of this research was to gain insight into the experiences of foster parents (N = 6) of elderly people with mental disorders. The results obtained from the research show that the motives for fostering elderly people with mental disorders are altruism, the need to help another person, the experience of fostering in the environment and the previous experience of caring for another person. Research participants cited cooperation with social workers and health workers, family help and support, and personal characteristics such as resourcefulness and versatility as helping circumstances in the provision of foster care. As aggravating circumstances of dealing with foster care, the participants cited the lack of information about the beneficiary before his arrival in the foster family and mutual familiarity between the beneficiary and the foster parent. The recommendations of foster parents for improving the quality of foster care are: increasing financial compensation for foster parents, professionalization of foster care and more education for foster parents.
