Correctional officers, often subject to sustained job stress and ambiguity, must possess adequate coping skills to deal with a hostile clientele. Psychological screening, therefore, assumes an important role in correctional officer recruitment. Prior to a recruitment drive, 650 employed correctional officers completed an MMPI and a biographical questionnaire, and were interviewed by an experienced officer, and, in some cases, by a counseling psychologist. Officers were rated as "acceptable" (N=448), "marginal" (N=164), or "not acceptable" (N=38). Date were obtained for the first 10 months of service regarding disciplinary actions, corrective interviews, absenteeism, and lateness. Those officers rated "not acceptable" were found to have significantly more corrective interviews, absences, and latenesses than did those in the other groups. Results indicate that formal psychological screening of correctional officers may be of practical and predictive value. (Author/NRB)
