Version V1

This data collection was designed to evaluate the effectiveness of a vocational training program on post-release vocational skills, employment, and recidivism of youthful male inmates 18 to 21 years old. The study used an experimental design to examine the differences in post-release activities among three inmate groups. A comprehensive inmate data base was created to describe inmates' confinement history, employment history, and their criminal records. The contextual data files provide additional information relevant to inmates' post-release activities.

Three study groups were formed in two stages of the study: an external comparison group, an internal control group, and an internal experimental group. A random sample was internally selected from two diagnostic centers: Polk and Harnett Youth Centers for Youthful Inmates ages 18 to 21 in North Carolina. The sample was divided into two categories: an external comparison group and an experimental-control group designated for transfer to the Sandhills and Cameron Morrison Youth Centers. The transferred group members were screened by additional criteria for sample selection. Qualified members were then randomly assigned to either the experimental group or to the internal control group. These three groups resulted in 295 experimental group cases, 296 internal control group cases, and 236 external comparison group cases.
