This study investigated the relationships between personality prototypes and life skills to understand the characteristics of Resilients, Overcontrollers, Undercontrollers, and Not identifiables. Hierarchical cluster analyses using Ward’s method and one-way ANOVA with multiple comparisons using Holm’s method indicated that Resilients tended to adopt adaptive behaviors and thoughts, and Overcontrollers had similar tendencies as Resilients. Additionally, Undercontrollers showed a tendency to adopt active interpersonal behaviors and thoughts, and Not identifiables tended to adopt accepting interpersonal behaviors and thoughts. These results provide new findings on the characteristics of individuals classified as different personality prototypes.
