Inmates are referred to the special unit based on their disruptive behavior at other establishments. Of 50 inmates who entered C Wing for the first time, up to the end of February 1992, 37 were transferred for various reasons: 20 were moved in a reasonably positive way, four were transferred to special hospitals, four were transferred to other special units, and 20 were moved quickly via the segregation unit. Seven inmates returned to the special unit, having spent an average of 25.86 months in the main prison system. Of this group, only three were transferred progressively off the special unit. Although marked decreases were generally observed in the disruptive behavior of inmates in C Wing, a pattern appeared to be established in which a peak in offending occurred 9 to 12 months after transfer to normal locations. 4 references and 4 tables
