Models of behavior change play a critical role in addressing HIV/AIDS, particularly in contexts of prevention, stigma reduction, and promoting adherence to treatment. HIV is primarily transmitted through behaviors such as unprotected sexual activity, sharing of contaminated needles, and from mother to child during pregnancy, childbirth, or breastfeeding. Hence, modifying high-risk behaviors is central to controlling the epidemic. Behavior change models provide a structured framework to understand why people engage in certain behaviors, what motivates change, and how interventions can be designed to encourage safer practices. One of the most widely applied models is the Health Belief Model (HBM). This model suggests that individuals are more likely to take preventive action if they perceive themselves as susceptible to HIV infection, believe that the consequences of the disease are severe, recognize the benefits of protective behaviors, and perceive fewer barriers to adopting these behaviors. For example, condom use is more likely when individuals believe it effectively prevents HIV and understand the risk of contracting the virus. In the context of stigma, HBM also helps explain why some people may avoid testing or treatment; perceived social or psychological barriers such as fear of discrimination may outweigh perceived benefits, highlighting _______ ___ _____ __________ ______ ___ ____ _____.
