Based on length of incarceration, 3 samples were drawn from the Ohio State Reformatory in Mansfield Ohio, a facility for youthful offenders under 30 years of age. Sample 1 was incarcerated for 6 months, sample 2 for 12 months, and sample 3 for 18 months. The method of analysis was the Multivariate Taylor's Manifest Anxiety Scale, Psychopathic Deviate Scale 4 and Analysis of Variance. The Leary scale was used to see if it could differentiate effectively within a general prison population. Results showed that the more normal an individual is, the more incarceeration will be disruptive to him. For the less stable individual, a longer period of incarceration may enhance his parole adjustment. The study indicates that should minimum terms increase and judicial remedies such as shock probation be disbanded, individuals typed as stable would exit significantly affected by prison and their chances of recidivating would increase. Findings indicated that no differences exist between offender types relating to incarceration, and that either a moratorium on the determinant sentence is desirable or that alternative remedies be continued. Tabular data, footnotes, references, and numerous appendixes accompany the study.
