The study is an attempt to measure psychopathic tendencies in the girl who becomes pregnant out of wedlock compared with the average non-pregnant college co-ed. This characteristic, when evidenced in a subject's personality, may be reflected in a High T score on the Pd scale of the 1MPI.

It is the basic assumption of this study that a relationship exists between the interpersonal needs of inclusion, control, and affection and occupational choice as indicated by college major. Studies in the area of vocational choice have largely dealt with people who are practicing the vocation, leaving doubt as to whether people are attracted to the vocation as a result of need-satisfaction behavior, or whether the people determine their orientation by practicing the occupation. The need for further clarification of these questions was recognized, and this study was an effort to add to the evidence for or against the validity of the concept of interpersonal need satisfaction as a factor in vocational choice.
