On the basis of previous research, which revealed difference in self-perception of disadvantaged and advantaged children, this project investigated whether differences in personality traits existed and what these differences might be as revealed by their self-perceptions. Fourth through eighth graders in an urban school system were subjects. About 200 subjects were disadvantaged, and about 300 subjects were from an advantaged area of the same city. Forty bipolar traits were expressed in sentence form, and children rated themselves on the inventory, indicating their self-concepts. Results showed higher percentages on the positive personality traits for the disadvantaged and revealed greater differences between boys than between girls. The disadvantaged, more than the advantaged, tended to see themselves as independent, competent, patient, and deliberate; while the advantaged perceived themselves as happy, self-confident, trusting, fearless, and worthy. Despite differences, both groups had higher percentages of responses in the positive end of the continuum, indicating that disadvantaged children do not necessarily reveal negative personality traits in their self-perceptions. Data also indicated that these differences did not necessarily mean that one group had negative personality traits and the other had positive personality traits. (DO)
