Step-by-step explanation:
Lupe is examining how social support may buffer the negative effects of stigma on the well-being of HIV-positive gay men of color. Based on the nature of this research, Lupe is most likely a health psychologist. Health psychologists focus on how biological, social, and psychological factors influence health and illness. Their work includes exploring how individuals cope with stress and examining interventions to promote health and well-being among diverse populations. The research mentioned involves understanding how emotional support can reduce psychological stress caused by discrimination, which closely aligns with a health psychologist's objectives.
Research has consistently shown that social support has significant effects on health outcomes, with strong social relationships being linked to a greater likelihood of survival. Studies have indicated that having readily available emotional support from friends and family can lessen distress caused by discrimination, illustrating the buffering role of social support. However, while such support can reduce the impact of discrimination, it is also necessary to continue anti-discrimination efforts to address the root causes of stigma and inequality, which are central concerns for health psychologists.
