Results indicate the major source of information for the patients was the media; the preferred source was the hemophilia treatment center. Most patients wanted more information about the treatment of AIDS and how to cope with the stresses of AIDS. Although patients indicated they had received sufficient information about the sexual transmission of AIDS, answers to knowledge questions indicated important misconceptions. Although the results strongly suggest the need for additional information about sexual transmission of HIV, they also indicate hemophiliacs do not recognize this need. Consequently, programs emphasizing sexual information will not be widely used by hemophiliacs. Efforts must help hemophiliacs recognize their need for additional information about sexual transmission of the virus before patient education can be effective. 5 tables, 21 references.
