On the basis of the literature review trait theory of personality, ego development of personality, cognitive theory of personality, and relevant empirical research concerning about adult personality development, this study constructed an integrated concept of adult personality development: Personality traits show temporal stability and some personality traits change in mean levels across adulthood. Eight personality traits were identified that were reasonable to describe the personality of middle-aged and old adults. This study adopted the perspectives of cognitive theory of personality to examine the stability and change of eight self-perceived personality traits across three major phases of adult life (young adulthood, middle-aged adulthood, old adulthood). Two scales were administered to 219 middle-aged and old adults. Self-perceived personality was rated by varying instructional conditions to include concurrent, prospective, and retrospective self-assessments. Results revealed that eight self-perceived personality traits showed moderate to high stability across three adult stages. In addition, both middle-aged and old adulthood have higher self-perceived generativity, integrity, interiority, maturity, and empathy than young adulthood; both young and middle-aged adulthood have higher self-perceived complexity and energy than old adulthood. |
