This study aimed to inform decisions about the risk assessment of men convicted of sexual offences. It did this by testing the predictive validity for sexual reoffending – the ability to separate lower- and higher-risk individuals – of two actuarial risk instruments, the OASys Sexual Reoffending Predictor (OSP) and the Risk Matrix 2000/s.
