3.2 Recruitment of Participants The instrument’s application procedure was preceded by an authorization of the School’s Principals. This researcher presented the research’s objectives to both Principals and its importance to the mutual comprehension between Brazilians and Portuguese about their Cultural Patterns and the preferred Leadership Style from the standpoint of the subordinates. However, it was clarified to both groups that the results would be considered keeping in mind the groups researched, that is, it was not the intention of the research to generalize the results. For this, other researches should be developed taking into account different social groups in different kinds of organization and different regions in each Country. Nevertheless, for both Principals it was pointed out the research’s results could be important information about the leadership style preferred by the subordinates, and, consequently, could help them dealing with the subordinates concerning the decision-making process. We argue that the findings can be used to build leadership programs in order to develop leadership skills among professors and their superiors. To the Portuguese Principal was also pointed out that researches about leadership in Portugal are almost inexistent (Jesuíno, 2007) and, consequently, this study and its results could be a contribution so that other researches regarding this subject could be developed.
