title: Personality deviancy and prison incarceration.
abstract: This investigation was designed to study personality differences among prison inmates that could be attributed to the number of felony offenses and the length of incarceration. MMPI profiles of 93 inmates of a medium security prison were obtained and analyzed. Special attention was directed to the five MMPI variables K, D, PD, SC, and MA. These five variables taken collectively successfully differentiated first offenders from repeaters and short-term from long-term inmates. The results support the hypothesis that increased incarceration has a harmful effect upon personality.
