Mental Symptoms, Life Satisfaction and Sexual Orientation: A Gender Analysis.

Research has revealed that homosexual and bisexual people are at higher risk of mental health problems than heterosexual people. However, most studies have focused on differences in disorders and have not examined the intersection of gender and sexual orientation. The main aim of this study is to investigate the relevance of sexual orientation in women's and men's mental symptoms, life satisfaction, and self-esteem. A cross-sectional study was conducted with 309 women and men who were homosexual or bisexual and 309 women and men who were heterosexual, aged between 17 and 54. All participants were assessed by four self-reports measuring mental symptoms, life satisfaction, self-esteem, masculine/instrumental and feminine/expressive traits, and traditional gender role attitudes. Results showed an interaction between sexual orientation and gender, with lesbian or bisexual women scoring higher in severe depression symptoms and lower in life satisfaction than heterosexual women. Homosexual and bisexual people scored higher than heterosexuals in somatic symptoms, social dysfunction, and in self-esteem. Women scored higher than men in somatic, anxiety, and insomnia symptoms and in feminine/expressive traits, whereas men scored higher than women in traditional gender role attitudes. We conclude that sexual orientation and gender are relevant to the mental health and well-being of people.
