This article approches the problem of organizing an effective AIDS pre
vention campaign through the establishing of a dual-strategies techniq
ue based on persuasive and behavioral stategies that integrate the res
earch into commitment psychology. The dual-strategies technique was te
sted in an actual environment within the campaign for the prevention o
f AIDS involving 17 and 18 years old subjects. A Likert-type attitude
scale was created to measure the results of the campaign. The experime
ntal plan permitted the verification of the effects of this strategy o
n attitudes by the comparison between the various groups that were sub
jected to different strategies and the control group, As we expected,
the pupils who were the object of these strategies showed more favorab
le attitudes towards AIDS prevention in the post experimental phase th
an those who were not (control condition).
