Some NEO-PI five-factor personality profiles

The aim of this study was to identify any clusters of score profiles to be found in a college sample of 236 subjects administered the five-factor NEO [Neuroticism, Extroversion, Openness] Personality Inventory (Costa & McCrae, 1985). Application of Ward's agglomerative hierarchical procedure to the score profiles disclosed six clusters that were replicated in a K-means partitioning process. The six clusters were then compared by a one-way analysis of variance (ANOVA) with respect to their mean five higher order scores on the Interpersonal Style Inventory (Lorr, 1986). The highly significant F tests provided confirmation of the characteristics of the cluster profiles isolated.
