An evaluative research study was undertaken to provide the South African broadcasting industry with information on the feasibility of using video mass media approaches for public education on the Acquired Immune Deficiency Syndrome (AIDS). Specifically, the research was designed to determine public knowledge of and attitudes toward AIDS and shifts in knowledge and attitudes after viewing a teletext program on the disease. Study respondents were administered questionnaires prior to and after viewing the teletext program. Most respondents ranged in age from 17 to 25 years. Results indicate that: (1) respondents had a positive reaction to the teletext program; (2) the knowledge level of the viewers was raised significantly; and (3) respondents changed their opinions of AIDS in a number of ways. Since only a small number of South Africans possess teletext decoders and since the leading information source of the public is television, it is recommended that suitable AIDS programming be developed or purchased for airing on South African television.
