Comprehensive in scope and international in outlook, it offers an integrated overview of key topical areas, from history and context, identities and fluidity, families and relationships, to health and wellbeing. This third edition includes updates across all chapters that provide a greater focus on diversity and utilize new terminology throughout to reflect changes in the field. It addresses recent developments in the field of trans studies, and explicitly references emerging work around pansexuality and asexuality. An entirely new chapter focuses on a diversity of topics receiving increased attention including LGBTIQ+ people in foster care, LGBTIQ+ refugees, disabled people accessing services, and trans and intersex people in sport. The fallout of increasing far-right extremism in Europe and America is also discussed. This groundbreaking textbook is an essential resource for undergraduate courses on sex, gender and sexuality in psychology and related disciplines, such as sociology, health studies, social work, education and counselling.

‘This third edition is a comprehensive text that thoroughly addresses the diverse lives of the LGBTQIA+ community while incorporating current psychological research. The book’s wide array of content, its inclusivity of various groups with a strong focus on intersectionality, and its easy-to-read, relatable material make it an exceptional resource for understanding and teaching LGBTQIA+ psychology. Its thoughtful integration of contemporary issues and diverse perspectives ensures it remains an invaluable tool for both educators and students.’

‘This is a fundamental text for anyone who teaches, studies, or has an interest in LGBTIQ+ psychology. It provides a good balance of background detail and the most current research on several key areas. One of its strengths is the inclusion of often forgotten subgroups within the LGBTIQ+ umbrella, offering useful insights into sometimes scarce evidence and suggesting future directions for research. I’m happy to recommend it and will continue to use it in my teaching.’

Nuno Nodin - Royal Holloway, University of London

‘No other textbook offers an introduction to the field that is so well developed and nuanced. This is an outstanding examination of the field that includes the important and necessary influences from critical theories. It is an intersectional analysis of theory, practice, research, and lived experience of LGBTIQ+ communities and individuals.’

Kristen Payne - University of Wisconsin-Milwaukee

‘This is currently the best available introductory academic textbook covering historical and contemporary LGBTIQ+ issues from a psychological perspective. It is thorough and every new edition incorporates knowledge and discussion around less researched and developing topics such as intersectionality. It is very easy to read and includes thought-provoking questions and scenarios that can be used to initiate discussion. I recommend it to academics and students who design or attend gender- and sexuality-related psychology modules. It’s on top of my reading lists for such modules.’
