In Study I, psychological influence of retirement and the way to deal with it were analyzed by giving the SCT to 220 men. The following seven Retirement Recognition Types were found: A: The Active-Welcomer, B ; The Passive-Welcomer, C: The Neutral, D: The Crisis, E: The Resignated, F: The Escaper and G: The Ambivalent. These seven types were classified into four Marcia (1964)'s Identity Statuses.
