The present study aims at validating the German version of the Structured Assessment of PROtective Factors (SAPROF) for violence risk in a representative sample of incarcerated adult male sexual offenders. Sexual offenders ( n = 450) were rated retrospectively with the SAPROF using the database of the Federal Evaluation Centre for Violent and Sexual Offenders (FECVSO) in the Austrian Prison System. Interrater reliability and predictive validity of the SAPROF scores concerning desistance from recidivism were calculated. Concurrent and incremental validity were tested using the combination of the SAPROF and the Sexual Violence Risk–20 (SVR-20). Interrater reliability was moderate to excellent, and predictive accuracy for various types of recidivism was rather small to moderate. There was a clear negative relationship between the SAPROF and the SVR-20 risk factors. Whereas the SAPROF revealed itself as a significant predictor for various recidivism categories, it did not add any predictive value beyond the SVR-20. Although the SAPROF itself can predict desistance from recidivism, it seems to contribute to the risk assessment in convicted sexual offenders only to a limited extent, once customary risk assessment tools have been applied. Implications for clinical use and further studies are discussed.

Risk is a pervasive feature of contemporary life, and has become a key feature of penal policy, systems of punishment, and criminal justice services across a number of the Anglophone jurisdictions. Risk as an approach to calculating the probability of “danger” or “hazard” has its roots in the mercantile trade of the 16th century, growing in significance over the intervening centuries until it pervades both the social and economic spheres of everyday life. Actuarialism, that is the method of statistically calculating and aggregating risk data, has similar roots, steeped in the probability calculations of the insurance industry with 20th-century extension into the arenas of social welfare and penality. Within criminal justice one of the first risk assessment tools was the parole predictor designed by Burgess in 1928. Since then we have seen a burgeoning of risk assessment tools and actuarial risk practices across the penal realm, although the extent to which penality is totally risk based is disputed. Claims for a New Penology centered on risk have been much debated, and empirical evidence would tend toward more cautious claims for such a significant paradigm shift. Prevention and responsibilization are often seen as core themes within risk-focused penality. Risk assessment is used not only to assess and predict future offending of current criminals, but also to enable early identification of future criminals, “high crime” areas, and those in need of early interventions. The ethics, accuracy, and moral justification for such preventive strategies have been extensively debated, with concerns expressed about negative and discriminatory profiling; net-widening; over targeting of minority groups especially for selective incarceration; and more recently criticisms of risk-based pre-emption or “pre-crime” targeting, particularly of ethnic minorities. Responsibilization refers to the techniques of actuarial practices used to make persons responsible for their own risk management, and for their own risk decisions throughout the life course. In respect of offenders this is best expressed through corrective programs focused on “right thinking” and re-moralizing offenders toward more desirable social ends. Those offenders who are “ripe for re-moralization” and who present a level of risk that can be managed within the community can avoid custody or extended sentencing. Those who are not, and who present the highest levels of risk, are justifiably selected for risk-based custodial sentences. Such decision-making not only requires high levels of predictive accuracy, but is also fraught with severe ethical challenges and moral choices, not least about the desired balance between risks, rights, and freedoms.

AbstractViolence risk assessment tools are increasingly used within criminal justice and forensic psychiatry, however there is little relevant, reliable and unbiased data regarding their predictive accuracy. We argue that such data are needed to (i) prevent excessive reliance on risk assessment scores, (ii) allow matching of different risk assessment tools to different contexts of application, (iii) protect against problematic forms of discrimination and stigmatisation, and (iv) ensure that contentious demographic variables are not prematurely removed from risk assessment tools.
