| QUICK ANSWER |
| A research synthesis found elevated depression and anxiety outcomes among bisexual people compared with heterosexual people, and often compared with gay or lesbian people. These are group-level disparities, not evidence that bisexuality causes mental illness. Researchers examine stigma, identity invalidation and access to support as possible contributors. Individual experiences and needs vary. |

Research that combines bisexual, gay and lesbian populations may obscure differences in experiences and mental health outcomes. Examining bisexual people’s circumstances separately can help researchers and clinicians identify barriers that might otherwise be missed. This does not mean bisexual identity determines a person’s wellbeing or that everyone who identifies as bisexual experiences distress.
Bisexual-Specific Mental Health Disparities
A 2018 systematic review and meta-analysis by Ross and colleagues examined depression and anxiety across bisexual, gay or lesbian, and heterosexual groups. It reported a pattern of poorer outcomes among bisexual participants compared with heterosexual participants and often with gay or lesbian participants. Differences in samples, measures and social contexts limit conclusions about any particular person and about the causes of the observed differences. For related reading, see LGBTQ+ mental health.
Minority stress research considers the role of discrimination, anticipated rejection and access to social support. Some bisexual people may encounter assumptions that they must choose a single category or that their identity changes with their relationship. Others have supportive friends, partners and communities. Avoid treating visibility or disclosure as obligatory: privacy can be a reasonable choice. For related reading, see mental health awareness.
| RESEARCH NOTE: Biphobia From Both Directions Research |
| Feinstein and Dyar’s 2017 review discusses bisexual-specific forms of minority stress, including negative stereotypes, invalidation and rejection. These can occur in different social settings. The review highlights possible pathways to health disparities, while recognizing gaps in the evidence and variation across individuals. |
Bisexual Erasure and Identity Invalidation
Bisexual erasure refers to ignoring, denying or misrepresenting bisexual identities. For example, a person in a different-gender relationship might be presumed heterosexual, or a person in a same-gender relationship might be presumed gay or lesbian. Relationship history does not necessarily define someone’s sexual orientation. Respectful communication allows people to identify themselves without demanding that they justify or prove their identity. For related reading, see what good mental health actually looks like.
Repeated invalidation may contribute to stress, particularly when it occurs in relationships where a person expects support. The APA guidelines for psychological practice with sexual minority persons discuss specific concerns for bi+ clients, including stigma and identity nonaffirmation. These experiences should be considered alongside other circumstances, not treated as the sole explanation for every mental health concern. For related reading, see identity crisis.
Bisexual-Specific Mental Health Support
A supportive clinician should assess the concerns that brought a person to care and ask about identity-related experiences when relevant. It is equally important not to assume bisexuality is the cause of distress or that a person seeks help with their orientation. Bisexual people may need care for unrelated concerns, including sleep difficulties, work stress, depression or anxiety. Evidence-based clinical care should be adapted to their needs.
Practical support may include respectful relationships, trusted peers or bisexual-inclusive community resources if these are accessible and welcome. A person does not need to disclose their orientation publicly to receive support. If distress persists, interferes with daily life or creates safety concerns, consider consulting a qualified mental health professional. Someone at immediate risk of self-harm should seek urgent local assistance.
| KEY TAKEAWAY |
| Bisexuality is a valid sexual orientation, not a mental disorder. Recognize bisexual-specific stressors without assuming everyone experiences them. Respect self-identification, avoid inferring orientation from a partner’s gender, and offer qualified support when mental health concerns arise. |
Frequently Asked Questions
Do bisexual people have worse mental health than gay and lesbian people?
A systematic review found elevated depression and anxiety outcomes in bisexual groups compared with heterosexual groups and often gay or lesbian groups. This is not a prediction about individuals.
What is biphobia and how does it affect mental health?
It refers to prejudice against bisexual people, including stereotypes and invalidation. Such experiences may contribute to minority stress.
What is bisexual erasure?
It means denying or overlooking bisexual identity, for example by assuming orientation from a partner’s gender.
Why are bisexual people less likely to be out?
Some people may prefer privacy or anticipate invalidation or rejection. Reasons differ, and disclosure is a personal choice.
What does bisexual-affirming mental health care involve?
It respects bisexual identity and individual needs, assesses relevant stressors without assumptions, and offers appropriate evidence-based mental health support.
