Estimate probability (risk) of future criminal behaviour. Risk assessment should be foundation of treatment and management. Civil settings: e. g. , civil commitment, custody disputes, marriage disputes, people who are considered too dangerous after being let out of prison, taken to a psychiatric hospital. Criminal settings: e. g. , pre-sentencing, pre-release, supervision, being declared a dangerous offender, assessments for parole boards. Risk factor: measurable feature of an individual that predicts the behaviour of interest. Static risk factors: fixed variables predictive of criminal behaviour (not changeable through intervention, e. g. , criminal history. Dynamic risk factors: changeable variables predictive of criminal behaviour. When changed, are associated with corresponding increases or decreases in criminal behaviour: stable. The assessor predicts an offender will reoffend and he does reoffend: true negative (tn) The assessor predicts an offender will not reoffend and he does not reoffend. The assessor predicts an offender will reoffend and he does not reoffend: false negative (fn)
