The research reported here is the first published information describing the nature and extent of the phenomenon. The survey revealed that 38 percent of the total Pennsylvania probation/parole workforce has been victimized (assaulted, threatened, or intimidated) at least once. The rate rose to about 50 percent when only probation and parole officers who actively supervise cases were considered. Data generated by the survey demonstrate that the victimization of probation/parole workers in the line of duty is a serious and pervasive occupational health problem. 18 tables, 13 references.
