Introduction - Since the 1990s, research on the psychological well-being of gay and bisexual individuals has shown that their mental health is poorer than that of the general population. This can be explained by the stigma these individuals face due to their sexual minority status: these individuals are subjected to stressors, both when they are visible as a sexual minority and when their sexual identity is not known. Both visibility and invisibility are potential stressors that negatively impact the psychological well-being of LGB (lesbian, gay, bisexual) individuals. To understand these mechanisms, this article examines the links between psychological distress (suicidal thoughts, depression, anxiety) among cisgender lesbian and bisexual women and their parents’ knowledge and acceptance of their sexual identity. Materials and Methods - The self-administered online data collection from the Virage LGBT survey (INED, 2015–2016) provides a convenience sample of 2,500 cisgender women, including 1,000 lesbians and 500 bisexual women. Since the questionnaire assesses suicidal ideation, depression, and anxiety, it is possible to examine, using dichotomous logistic regressions, differences in the psychological well-being of respondents based on parental awareness and acceptance of their sexual identity. Results - Two main findings emerge. For cisgender lesbian women, parental awareness of their homosexuality is not associated with better psychological well-being, while the results for bisexual women are less clear-cut. However, while parental awareness of homosexuality or bisexuality is not necessarily associated with reduced distress, acceptance of this identity is strongly associated with it. Discussion-conclusion - The overall visibility of LGB people is, rightly so, a key issue in contemporary activism. On the other hand, the benefits of individual visibility appear less evident, particularly for cisgender lesbian and bisexual women, whose identity is often denied or considered temporary—and this is especially true within the family, where women’s sexuality is closely scrutinized.
