It aims to discuss further devel-opments in the personality research area. All of the research studies were arranged within a framework along four viewpoints: ( 1 ) studies dealing with personality traits comprehensively, ( 2 ) individual differences in psychological constructs or traits of personality, ( 3 ) social attitudes, and ( 4 ) development of personality and its relation to social adjustment and mental health. The following four points were found to be current research trends in personality studies, and their future directions are discussed. First, studies using meta-analysis or the secondary use of big data increase our understanding of personality traits, and further investigations using these methods are expected.
