The efficacy of the Historical, Clinical, and Risk Management Scales (HCR-20; C. D. Webster, D. Eaves, K. S. Douglas, & A. Wintrup, 1995), Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991), Beck Hopelessness Scale (BHS; A. T. Beck, A. Weissman, D. Lester, & L. Trexler, 1974), and Brief Psychiatric Rating Scale (BPRS) to predict violence and self-harm in 34 institutionalized mentally disordered offenders was assessed. Both the HCR-20 and BPRS were strong predictors of violence whereas the PCL-R had moderate predictive ability. BHS was the only variable predictive of self-harm. Although risk assessment measures were successful at predicting in-patient violence, a clinical measure of mental state was at least as effective in these mentally disordered offenders.

Pedophiles are motivated to disguise their thoughts and feelings about their sexual beliefs and attraction toward children. New developments using implicit measures of associations have been successful in accessing socially stigmatic beliefs, even in cases in which the participant is resistant to this disclosure. Using an implicit measure, the authors show that pedophiles have an association between children and sex, whereas nonpedophilic offenders have an association between adults and sex. The task can therefore identify a core cognitive abnormality that may underpin some pedophilic deviant sexual behavior.

This paper explores the genesis of sadistic behaviour in men and its relationship to crime. Sixteen male special hospital patients, each with a diagnosis of psychopathic disorder, formed the basis of this descriptive study. In only three cases were the crimes explicable in terms of external circumstances and personality traits. The offences of the remaining 13 cases became comprehensible only when the offender's internal circumstances were explored: investigation revealed repetitive sadistic masturbatory fantasies which had spilled over into overt behaviour because the patients had felt impelled to seek and create increasingly dangerous in vivo 'try-outs' of their fantasies. The paper discusses the crucial link between sadistic fantasy and behaviour.
