Nineteen selected self-perception characteristics of university students were related to sex and to ordinal position. The 60 selected males and 120 selected females were enrolled during the summer of 1976 at North Texas State University in Denton County, Texas. A self-rating, group-administered instrument was originated for collecting information. Ordinal positions were only child, first-born with later siblings, intermediate, and last-born. The intermediates had the most positive self-perceptions. Of the males, intermediates were highest and only children lowest. Of the females, only children reported more positive self-perceptions. Females had more positive self-perceptions than males. Effects of ordinal positions tended to depend on the child's sex. Further study was recommended utilizing a larger, more varied population.
