Le stress minoritaire, la violence conjugale et la santé mentale des femmes de la diversité sexuelle : une étude pancanadienne

Canadian and American population surveys show that people from the sexual diversity and gender-diverse people are more at risk of mental health problems (psychological distress, depression, anxiety disorders, substance use problems) and of being victims of intimate partner violence (IPV) in their lifetime. But the LGBTQ+ (lesbian, gay, bisexual, transgender, queer and other) community is not homogeneous: between the different subgroups of this population, sexual minority women (SMW) are at particularly high risk of experiencing stigma, mental health problems and being victims of IPV. This vulnerability can be explained by the sexual and gender minority stress model, stating that sexual and gender minority people suffer from specific stress factors added to general stressors, leading to more mental health and relationship problems. Those stress factors can be distal, such as prejudice events one suffers from based on their sexual or gender identity (harassment, discrimination, physical violence, etc.). But they can also be proximal, and therefore more subjective, such as expecting to be rejected or discriminated (also called stigma consciousness), concealing one’s sexual or gender identity, or suffering from internalized homophobia or transphobia.  The main goal of this Master’s thesis was to assess the impact of minority stress factors and of different forms of past IPV victimization on the current mental health of Canadian SMW, as a function of their sexual and gender identity.  In total, 209 individuals identifying as women (M age = 33,9), living in Canada and who lived in a violent intimate relationship with a woman in the past answered our online survey. Questionnaire assessed sexual orientation and gender identity, IPV behaviors, minority stress factors, and symptoms of depression and anxiety.  Hierarchical regressions showed that psychological aggression was positively associated with anxiety symptoms and sexual coercion with depressive symptoms. Not being strictly attracted to women (i.e. identifying as bisexual, pansexual, queer or something else) was also associated to high symptoms of depression and age was negatively associated to anxiety symptoms. After controlling for age, race/ethnicity, sexual and gender identity and IPV victimization, having negative feelings about being a SMW was strongly associated with both depression and anxiety symptoms.  This Master’s thesis provides new information on the interconnected associations among IPV, minority stress and SMW’s mental health. It shows the importance of LGBTQ+ specific stress factors, particularly of negative feelings about being a SMW, on the mental health of SMW IPV survivors. It highlights the necessity to evaluate the needs of SMW IPV survivors and, more broadly, of all sexual and gender minorities. This could allow clinical intervention to be more adapted to the needs of LGBTQ+ IPV victims and therefore help buffer against victimization they are faced by.
