This book focuses on the clinical, social and psychological aspects of HIV among gay men and examines the complex factors that can contribute to HIV risk in this key population. With the target to end all HIV transmissions in the UK by 2030 in mind, Jaspal and Bayley combine elements of HIV medicine and social psychology to identify the remaining barriers to effective HIV prevention among gay men. The authors take the reader on a journey through the history of HIV, its science and epidemiology and its future, demonstrating the vital role of history, society and psychology in understanding the trajectory of the virus. Underpinned by theories from social psychology and clinical snapshots from practice, this book considers how psychological constructs, such as identity, risk and sexuality, can impinge on physical health outcomes. This refreshing and thought-provoking text is an invaluable resource for scholars, clinicians and students working in the field of HIV.
