Profile patterns in the 16PF questionnaire.

The study goal was to identify the main clusters of 16PF score profiles to be found in a mixed sample of students and adults. The 300 subjects represented, half male and half female, were subdivided into three equal subsamples. To demonstrate replicability, the three subsamples were cluster analyzed by three procedures: Nonhierarchical average linkage, minimum variance, and K-means. Four profile clusters were identified and replicated across two or three samples and for all three methods. The results were compared with those reported by other investigators.
