A cluster analysis of the 16 Personality Factor Questionnaire, Hostility and Direction of Hostility Questionnaire and Psychological Screening Inventory scores from 181 delinquents at Deerbolt Borstal, England, revealed four personality types which were labelled ‘Withdrawn’, ‘Normal’, ‘Disturbed’ and ‘Truculent’. A 3-year reconviction follow-up showed that the groups differed in terms of recidivism. Sixty-four percent of the Withdrawn group reconvicted whilst 87% of the Normal, 79% of the Disturbed and 76% of the Truculent group reconvicted. Controlling for the influence of number of previous convictions the Withdrawn group differed significantly from the other groups in terms of recidivism. The results are discussed with reference to similar results obtained in a previously reported study in a detention centre.
