A recent study published in the journal Psychological Medicine indicates that the mental health challenges faced by gay men may primarily stem from family issues rather than minority stress.
According to the research, around two-thirds of the mental health disparity between heterosexual and non-heterosexual individuals can be explained when accounting for shared environmental and genetic influences.
The study posits that these disparities largely arise from factors that are both genetically relevant and common to both heterosexuals and non-heterosexuals who grew up in similar environments. It stresses that these elements are reflective of shared genetic and environmental backgrounds that also affect heterosexual families.
This figure clearly shows the results. The “Population” bar indicates the difference in effect size between non-heterosexual and heterosexual non-kin. The other two bars show family differences. Look at how quickly they decline. (10/n)

Professor Michael Bailey, one of the authors from Northwestern University, points out that this research challenges the sexual minority stress theory (SMST), which has long suggested that the increased levels of depression, anxiety, and suicide among gay men result from societal mistreatment.
He references a 2003 study that raised awareness of SMST, a theory that has been widely cited and has influenced funding decisions at the National Institutes of Health regarding mental health research disparities between heterosexual and transgender youth. Bailey notes that SMST has been a dominant theory for three decades.
Bailey expresses concerns about SMST by stating that mental health disparities continue, even as societal acceptance of sexual minorities grows in Western nations.
We hope that our method will be applied to gender dysphoria and transgender research. We have a database with the information we need. It is probably severely restricted for political reasons. Please remove these restrictions! (14/n)

“Our new study employs straightforward logic to assess the role of minority stress in mental health differences, and the conclusion is, not significantly,” Bailey articulates.
He further clarifies that the logic used is based on findings that show heterosexual families, including identical twins, often share similar mental health issues without experiencing the stresses associated with sexual minorities.
The study’s authors urge fellow researchers to explore alternative hypotheses regarding minority stress and are calling for the NIH to reconsider its funding priorities in this area. “To enhance mental health outcomes, we must look beyond the lens of minority stress,” suggests Bailey.
Bailey has a notable history in researching human sexuality, and his 2003 book, “The Man Who Becomes Queen,” delves into transgender issues. His decision to host a lecture by evolutionary psychologist Satoshi Kanazawa was met with pushback from over 4,000 petitioners in 2018, primarily due to Kanazawa’s controversial views on the genetic basis of intelligence.
