Lesbians and Their Sisters as a Control Group: Demographic and Mental Health Factors

Abstract

Lesbians and their heterosexual sisters were compared on demographic variables and mental health subscales, so that the feasibility of using heterosexual sisters as a control group for lesbians could be investigated Lesbians were significantly more educated, more likely to live in urban areas, and more geographically mobile than their heterosexual sisters. Heterosexual sisters were more likely than lesbians to be married and homemakers, to have children, and to identify with a formal religion. There was no difference in mental health, but lesbians had higher self-esteem. When all respondents were included, bisexual women had significantly poorer mental health than did lesbians and heterosexual women. This is the first study to use sisters as a control group in lesbian research.
