The training of all people on a correctional institution staff is discussed. The point is made that there are special problems about penal institutions in trying to effect behavior change in that people are living there against their will. This circumstance produces a basis for a subculture. It has been found that the criminal subculture is the most important dynamic in the correctional institution, as far as the operation of the institution and the training programs within it are concerned. This subculture contains: (1) the "adapters," or those people who come into an institution with very little prior experience of living in jails, (2) college kids who are caught for using "pot," another type of "adapters," (3) the "solid," the man who teaches the new people the ways of the subculture. It is stated that the most crucial consideration in the operation of an institution is that the warden's office or the administrator's office must be the center of operation. For purposes of this discussion, an "authority figure" is defined as anyone who works in an institution, excluding the inmates. Of special concern is the correctional officer, whose potential as a behavior change agent is an almost untapped resource. In order to change an inmate's behavior, a correctional officer must: (1) Have some contact with him; (2) Build up his trust; and (3) Help him out in a tough situation. (CK)
