Pattern of responses to HIV transmission questions: rethinking HIV knowledge and its relevance to AIDS prejudice.
This paper intends to investigate the connection between HIV transmission knowledge and prejudicial attitudes towards people with HIV/AIDS (PWAs), with an emphasis on exploring the pattern of cognitive profile in response to knowledge questions. Data for the present study were derived from the 'Health Attitudes and Health Seeking Behavior Study', a telephone survey of a nationally representative sample, aged 20 to 70, from April to May 1997 in Taiwan. A total of 2,471 respondents who had heard of AIDS and knew that it was infectious were included in the analysis. Based on answers to four transmission-route items (blood transfusion, mother-foetus, sexual contacts, needle sharing) and two casual-contact items (shaking hands and sharing utensil), a variable 'pattern of knowledge performance' was constructed, by which the respondents were clustered into five knowledge groups. Bivariate and multivariate analyses illustrated the greater explanatory power of pattern of knowledge performance rather than additive scoring of knowledge items to PWAs' prejudice. Moreover, it was the responses to casual-contact rather than transmission-route questions that made a greater contribution to PWAs' prejudice. Special attention is given to the possible perceptual undertaking inherent in the five types of knowledge group. To implement effective AIDS prevention campaigns and interventions, the design for increasing the risk perception of the correct HIV transmission routes should differ from that of reducing the risk perception of the casually transmitted routes.
