Impact of clinic based educational videotape on knowledge of AIDS in STD patients.

A case control intervention study was conducted on STD clinic patients to evaluate the effectiveness of videotape education about AIDS. A questionnaire containing 20 true or false type questions was administered to 50 study group participants before and after display of the videotape and to 50 control group participants who did not watch the tape. Before and after scores of each group were analyzed for statistical significance.
