This seminal book is the original and definitive text presenting gender, sex and relationship diversity (GSRD) therapy as its own therapeutic approach rather than simply a set of techniques or “add on” to other modalities in working with LGBTQ+ clients and other marginalised populations.

This edited volume draws on the expertise of international clinicians who offer contemporary perspectives as well as modernising traditional psychotherapeutic theories. The book introduces the modality by explaining the essence of GSRD therapy: its history, philosophy and theories, as well as what it is used for and how it is practiced. It sets the landscape for GSRD therapy, centred on its seven core components. It focuses on specific populations and themes that are prevalent in the GSRD communities, yet often not written about or discussed in core clinical training, such as working with queer and trans young people, parenting, working with serious mental health difficulties, and ageing and the end of life. It also covers topics such as neurodivergence, self-harm, and body image.

The book is a critical resource for clinicians worldwide, particularly those working with or interested in working with populations who do not fit the dominant “norm” of heteronormativity and mono-normativity and those who are gender-expansive.
