Ego development in the college years: Two longitudinal studies

Students from a two-year and a five-year college were tested twice at four-and four-and-a-half-year intervals using the Sentence Completion Test of Ego Development. In both samples retest scores were positively correlated with initial scores (0.39 and 0.49) and were significantly higher in ego level (typically a half-stage). These data are consistent with the developmental hypothesis that ego growth occurs according to a fixed sequence of stages, and suggest that rate of growth decreases with age. In one sample women were higher in ego level than men at the beginning of the study, but in neither sample were sex differences significant at retest.
