[영문]We systematically examine community reaction to persons living with HIV/AIDS (PHAs) and their older parents in Thailand. We focus on parents as well as PHAs because parents are major providers of care for their ill adult children. Our analyses are based on several sources of recently collected survey and qualitative data from a wide range of perspectives. We find important variations in community reaction to PHAs and their families, but overall these reactions are much more positive than is widely assumed. We conclude that much existing research on community reaction to AIDS neglects both a rich body of social theory on stigma and a strong tradition of population-based empirical research in sociology. Much existing research also fails to adequately distinguish between key aspects of the social settings where most AIDS cases occur and the social settings where most of the stereotypes surrounding AIDS-related stigma have originated. A closer marriage between empirical and theoretical approaches to social stigma is required to advance our understanding of this critically important dimension of the AIDS epidemic.
