ABSTRACT
The global HIV epidemic remains an unprecedented public health challenge with nearly 37 million people living with HIV in 2015 (Joint United Nations Programme on HIV, 2016a). Since the beginning of the epidemic, 78 million people have become infected with HIV, and nearly 35 million people have died from AIDS-related causes (Joint United Nations Programme on HIV, 2016b). Psychologists, recognizing the relevance of their theoretical models and approaches to attitude and behavior change, have played a pivotal role in the prevention and treatment of HIV (Backer, Batchelor, Jones, & Mays, 1988). The use of theoretical models and approaches to understanding and promoting HIV prevention continues to this day.
