Most studies of the psychosocial implications of HIV/AIDS have been focused on the individual. This paper reviews the small but growing body of research into the impact of HIV/AIDS on the family system. Special reference is made to definitions of the family, same‐sex relationships and the African family. The impact of HIV/AIDS on the family is discussed in terms of social stigma, isolation and secrecy, stress and coping, social support, communication and disclosure, responses to illness, and changing structure and roles in families. It is anticipated that in the 1990s, the study of the family will become a dominant topic in HIV/AIDS‐related research.
