This book focuses on the social psychological aspects of gay men's lives and provides a cutting-edge examination of topics including sexual orientation, sexual behavior, identity, relationships, prejudice, and health. The Social Psychology of Gay Men forces us to re-think existing theory and research, much of which has taken heterosexuality for granted. With identity process theory at its heart, this book advocates a social psychology of gay men which incorporates three levels of analysis – the psychological, interpersonal and societal. The book promises not only a deeper understanding of gay men's lives but also pathways for enhancing wellbeing, intergroup relations and equality in this key population. This illuminating and thought-provoking text is an invaluable resource not only for psychologists, but for students, scholars and practitioners working in the area of gay men's life.
