Article first time published onWhat are static risk factors?
Static risk factors are features of the offenders’ histories that predict recidivism but are not amenable to deliberate intervention, such as prior offences. In contrast, dynamic risk factors are potentially changeable factors, such as substance abuse and negative peer associations.
What is stable assessment?
The Stable-2007 is an instrument that measures factors which are potentially changeable but endure for months or years. The Stable 2007 consists of a guided interview process covering 13 major areas of stable risk in the offender, namely: Significant Social Influences.
What is the stable risk assessment?
The Stable-2007 and Acute-2007 (SA07) is a two-part actuarial risk assessment instrument designed to assist with the community supervision of individuals who have committed sexual offences.

What is the actuarial approach?
In particular an actuarial approach considers risks more broadly, seeking to understand the range of potential impacts and the interaction of risks, rather than adopting a distinct impact and probability for each risk separately.
What is an actuarial approach to risk assessment?
In contrast, the actuarial approach is purely mechanical and places individuals into a risk category based upon the presence or absence of a predetermined set of risk factors that usually have an empirically established relationship with the criminal behaviour in question.
How do Actuaries measure risk?
Actuaries use period life tables, which show the mortality rates of a specific population of individuals, during a given period of time, and they use cohort life tables, which show the overall rates of mortality for a specific population’s total lifetime.
How do you score an LS in CMI?
In addition, the LS/CMI classifies offenders into five different risk levels depending on where their total scores fall in the range. These risk levels consist of very low (a score between 0 and 4), low (5-10), medium (11-19), high (20-29) and very high (30-43).
What is the RNR model in corrections?
The risk-need-responsivity model is a model used in criminology to develop recommendations for how prisoners should be assessed based on the risk they present and what they need, and what kinds of environments they should be placed in to reduce recidivism.
What are criminogenic needs?
Criminogenic needs are characteristics, traits, problems, or issues of an individual that directly relate to the individual’s likelihood to re-offend and commit another crime.

What is a static factor?
Static Factors means energy-governing factors that are not usually expected to change (e.g., facility size, design and operation of installed equipment, number of weekly production shifts, or type or number of occupants). The associated static factors must be monitored for change throughout the reporting period.
What are static and dynamic risks?
Static risks are those which would exist in an unchanging world. … Conversely, dynamic risks are those risks which result from change itself. Dynamic risks may rise from significant changes in the frequency or severity of existing sources of loss or from completely new sources.
What is the difference between static and dynamic risk factors for violence?
Static risk factors are historical and do not change, such as family background, childhood abuse or seriousness of offending. … Dynamic risk factors, on the other hand, are changeable and hence offer the opportunity for intervention.
What is stability in research?
Stability is an aspect of reliability and many researchers report that a highly reliable test indicates that the test is stable over time. The definition of stability given by the Standards for Educational and Psychological Testing is ‘the extent to which scores on a test are essentially invariant over time.
