Most of the follow-up studies of correctional institutions have tried to, predict “success” and “failure” of inmates by correlating the latter with many personal and social factors of the inmates after they have left the institutions.
An exception to these studies are the “Institutional impact” projects carried out recently mainly in the U.S. These have aimed at isolating the impact of the correctional institution itself on the future behaviour of the released inmates. Our present project is a combination of both the traditional follow-up studies and the institutional impact ones.
The design of our study would include three time dimensions which would contain, presumably, the relevant independant variables. These are : the personal and soda (factors of an individual up to his entrance into the institution. This would include, of course, personality characteristics, family background, other socialization data, previous criminal history, membership in delinquent gangs, etc. The second dimension would be the actual stay in the institution and its effects, both “negative” and “positive”, on the inmate.
