Abstract
The purpose of this report was to review research on personality in some Japanese psychology fields. The report focused especially on the relationships between personality and psychological adaptation, as mental health and personal relationships. Reviewed research was based on questionnaire methods. Much research reviewed in this report investigated the effects of each trait on psychological adaptation, but not on the comprehensive personality. The points of temperament based on the biological personality theory, clarifying structure of traits, and distinction of similar traits were regarded as important perspectives. These perspectives might provide useful suggestions for effective intervention and solve contradictions in previous research that dealt with the effects of traits on psychological adaptation.
