This study introduces the possibility of the 9 th stage by Joan Erikson by adding Erikson's original theory of the 8 th stage and validates the gerotranscendece scale in later life. For this, 10 items from Erikson's scale was examined and the relationships among gerotranscendence, ego-integrity, and wisdom were examined using a sample of 244 elderly individuals over the age of 60. According to the results, the measurement of gerotranscendence based on Erikson was applicable to the Korean sample. In addition, ego-integrity and wisdom influenced gerotranscendence in later life. Based on these results, the validity of gerotranscedence, psychosocial development in the 9 th stage, discussed and the utility of Erikson's theory is emphasized.
