Illusory correlation
Decisions characterized by a substantial amount of professional discretion and lack of guidelines
Unstructured clinical judgment
Decisions are based on risk factors that are selected and combined based on their empirical or statistical association with a specific outcome
Actuarial prediction
Decisions are guided by a predetermined list of risk factors that have been selected from the research and professional literature. Judgement of risk level is based on the evaluator’s professional judgement.
Structured professional judgment
Risk factors that do not fluctuate over time and are not amendable to change (e.g., criminal history)
Static risk factor / historical risk factors
Risk factors that fluctuate over time and are amendable to change (e.g., antisocial attitude)
Dynamic risk factor
Risk factors that change rapidly within days, hours, or minutes and often occur just prior to an offence (e.g., level of intoxication)
Acute dynamic risk factor
Risk factors that reflect the individual’s traits, tendencies, or style (e.g., negative attitudes)
Dispositional risk factors
Types and symptoms of mental disorders (e.g., substance abuse)
Clinical risk factors
Risk factors that refer to aspects of the current environment (e.g., access to victims or weapons).
Contextual risk factors / Situational risk factors
