The document discusses conceptualizing stigma using a 5-component model of stigma proposed by Link and Phelan (2001). The components are discrimination, status loss, separation, stereotyping, and labeling. It is noted that the components do not need to occur in a specific sequence for stigma to be present. Examples are provided to illustrate how stigma can occur through social processes even without direct discrimination of individuals. The psychology of both the stigmatized and stigmatizing individuals is examined. Various research on stigma related to HIV/AIDS is summarized. Educational approaches and strategies for addressing stigma using the model are explored.
