The present study evaluates the personal values that inform a sample of participants in a open format of response that permit the participants identifying and prioritizing their top ten life values. In addition, participants were asked to report of the principal values of the majority of persons of his/her same age and of the people of different ages. The sample was made up of 449 participants (40,3% men, 59,7% women) that were distributed in three groups of young people (N= 196), adult people (N= 154), and senior people (N= 99). The results indicate, principally, that the reports of personal values and generational values are very similar in case of adult and senior people, and very different in the case of young people, with the presence of negative and postmaterialistic values. The results are discussed in the frame of the theory on intergenerational change of values.
