Results of a pre-experimental research carried out with 82 students of 3rd ESO (14-16 years old) enrolled at a high school in Madrid. This research aims at getting to know these students’ attitude towards disability, as well as evaluate whether this attitude changes through the application of an intervention programme consisting of the three attitudinal components: cognitive (idea), affective (emotion) and behavioural (predisposition to action).To assess these changes, it has been used an adapted version of Verdugo, Arias and Jenaro’s questionnaire (1994).The results achieved show the efficiency of the program in that the differences between the first and final tests are significant.
