In compact, statistical fashion, an eight-year follow-up study of university students is presented which used interviews, interviews with family and neighbors, and other sources of information. Negative findings, such as the need to exploit others and the need to accumulate material things, characterized fifty-nine percent of the medical students at the University of Mexico. The most disturbed group was found to be those medical students who went into the study of psychoanalysis; the second most disturbed being the engineers.

The article is so compact, the tests described so new, and the literature was reviewed so thoroughly that it deserves to be translated.
