Although it is well established that women experience significant gendered oppressions when accessing mental health services, research exploring the impacts of involuntary mental health services is frequently conducted without attending specifically to gender. This article reports on a qualitative study that explored women's experiences of compulsory mental health treatment in Australia. In-depth interviews revealed substantial gendered harms experienced by women within involuntary mental health treatment settings. Themes identified were: involuntary treatment replicates the dynamics and tactics of gendered violence; treatment involves profound deprivation and losses, with potential implications across the lifecourse; mental health services disrupt and undermine mothering; and recovery is found outside of coercive mental health systems. The study reveals the heightened harms experienced by women within involuntary mental health contexts, as well as women's strategic resistances to psychiatric oppression. It demonstrates the relevance of a conceptual lens that is attuned to gender, in order to develop a deeper understanding of women's experiences of intersecting oppressions within involuntary mental health settings. Implications include the need for alliance-building across feminist and critical mental health movements, and the need for a much more robust engagement by the social work profession in challenging the widespread acceptance of involuntary mental health treatment.
