OBJECTIVES: Non-monosexual women -those who report attraction to or sexual relationships with individuals of more than one gender -have elevated risk for poor mental health outcomes. We aimed to examine which elements of non-monosexual experience are associated with this elevated risk.
METHODS:We conducted a sequential exploratory mixed methods analysis of qualitative interview and survey data from 39 non-monosexual women recruited consecutively through prenatal care providers. Qualitative analyses identified distinguishing features, and quantitative analyses tested associations between these features and mental health symptoms.RESULTS: Nine qualitative themes were identified to describe distinguishing features of non-monosexual women. Of these, current and past five years partner gender, lack of LGBTQ community connection, and low centrality of sexual minority identity were associated with anxiety symptoms. Latent class analysis revealed significantly higher levels of anxiety symptoms among non-monosexual women partnered with men relative to those partnered with women.CONCLUSION: Sexual minority women who partner with men may be particularly at risk for poor mental health. Considering this group's invisibility in public health research and practice, interventions are needed to address this disparity.KEY WORDS: Bisexuality; mental health; qualitative research; questionnaire design La traduction du résumé se trouve à la fin de l'article.Can J Public Health 2017;108(3):e296-e305 doi: 10.17269/CJPH.108.5884 S exual minority women (SMW; e.g., lesbian, bisexual) report higher rates of mental health problems compared to heterosexual women, 1,2 and bisexual women in particular report higher rates of poor outcomes than both lesbian and heterosexual women. 3,4 More limited evidence suggests that these disparities also extend to people of other sexual identities who report sexual attraction to or behaviour with both men and women. For example, studies have found elevated levels of outcomes such as psychological distress among "mostly heterosexual" individuals. 5,6 Considering that the identified health disparities appear to be associated with a variety of sexual orientation self-identities (including bisexual, mostly heterosexual, and queer, among others), recent research has turned to trying to understand the health status and predictors for the broader group of individuals reporting sexual attraction to and/or behaviour with both men and women -a group that has been collectively termed non-monosexual 7 or plurisexual 8 people.One challenge to this emerging body of research is the diversity of experience that is included within non-monosexual groupings. For example, non-monosexual categories may be defined on the basis of self-identity, sexual behaviour across a particular time period, or self-reported sexual attraction. Each of these definitions will capture a different group of women, 9,10 and may include women with a variety of sexual orientation identities, women who are currently partnered with people of va...
