The AIDS educational lecture is a school-based intervention that informed
adolescents about AIDS through a lecture that is based on the transcript of a
film. (An alternate format, a film version of the intervention, is discussed

here. Positive impacts of the AIDS educational lecture were found for AIDS
knowledge and attitudes towards AIDS patients at post-test. Although these
impacts had dissipated somewhat by the one-month follow-up, a significant impact
remained. There was also a positive impact on attitudes towards practicing
preventive behaviors at post-test, but it disappeared by the one-month


Target population:

This AIDS educational lecture is a 45-minute school-based intervention, which
consists of a 18-minute lecture on AIDS, which is based on the transcript of a
film of the same length. The lecture is followed by an additional 8 minutes of
information on AIDS presented in lecture format and 15 minutes of question and
answer. The intervention aims to increase adolescents’ knowledge of AIDS,
positive attitudes toward AIDS patients, and positive attitudes toward
practicing preventive behaviors.


Evaluated population:
Participants were 448 tenth grade students at two suburban public high schools
near Oklahoma City. The sample was 56 percent female, and the average age was

Classrooms were randomly assigned to hear the lecture, watch the film that the
lecture was based on, or to receive no program. Data were collected on AIDS
knowledge, attitudes toward AIDS patients, and attitudes toward practicing
preventive behaviors one week before the intervention, immediately following the
intervention, and one month after the intervention.

AIDS knowledge increased from pre-test to post-test, but then decreased between
post-test and follow-up. However, knowledge at follow-up was still significantly
higher than at pre-test. Students who heard the lecture had more knowledge of
AIDS at post-test and follow-up, compared with students in the control group.
Students who heard the lecture had slightly, but significantly, higher knowledge
scores than those who saw the film. At both post-test and follow-up, students
who heard the lecture had more positive attitudes towards AIDS patients than
students in the no-treatment control group. (However, there were no differences
between the lecture group and the film group on attitudes towards AIDS
patients.) Attitudes towards practicing preventive behaviors increased
significantly from pre-test to post-test, but then decreased by follow-up to
pre-test levels and were no longer significantly different than the control
