When it comes to managing and rehabilitating sex offenders, it’s crucial to have effective tools that assess the likelihood of reoffending. One such tool is the Minnesota Sex Offender Screening Tool-Revised, commonly referred to as MnSOST-R. This assessment instrument plays a vital role in the criminal justice system by helping professionals evaluate the risk posed by sex offenders and make informed decisions about their treatment, supervision, and release. In this blog post, we will delve into what the MnSOST-R is, how it works, its accuracy, and its impact on sex offender rehabilitation.
What is the Minnesota Sex Offender Screening Tool-Revised (MnSOST-R)?
The Minnesota Sex Offender Screening Tool-Revised, or MnSOST-R, is a risk assessment tool developed by Dr. R. Karl Hanson and his colleagues in response to the need for a standardized and empirically validated instrument to assess the risk of sexual reoffending among convicted sex offenders. The MnSOST-R is one of the most widely used sex offender risk assessment tools in the United States. MnSOST-R is used primarily by criminal justice professionals, including probation and parole officers, psychologists, and therapists, to assist in the evaluation and management of sex offenders.
How does MnSOST-R Work?
MnSOST-R is designed to predict the risk of sexual reoffending within a specific time frame, usually five years following an individual’s release from prison or reentry into the community. The assessment involves gathering information about the offender’s history, criminal record, and personal characteristics, which are then used to calculate a numerical score.
The MnSOST-R is a 16 item, self-report questionnaire that is administered to sex offenders by trained professionals. The assessment items in MnSOST-R cover a range of factors that have been found to be relevant in predicting recidivism.
Some of the risk factors measured to help predict sexual recidivism include:
- Age at first offense
- 2. Number of prior sex offenses
- Type of prior sex offenses
- Victim age
- Victim relationship
- Use of force or coercion
- Mental health problems
- Criminal history
- Employment status
- Education level
Some of the protective factors measured reducing the likelihood of sexual recidivism include:
- Age
- Marriage
- Employment
- Stable housing
- Treatment participation
- Social Support
These identified factors can be broadly categorized into three main domains:
Historical Factors
This domain includes factors such as prior sexual offenses, age at first offense, and the number of prior non-sexual violent offenses. Research has shown that individuals with a history of sexual offenses are at a higher risk of reoffending.
Static Factors
These are characteristics that are relatively stable and do not change over time. They include factors like gender, relationship status, and victim age preference. Static factors are used to provide a baseline risk assessment.
Dynamic Factors
Dynamic factors are variables that can change over time and are amendable to intervention or treatment. They encompass factors such as deviant sexual interests, attitudes supportive of sexual offending, and the presence of a stable residence and employment. Addressing dynamic factors through therapy and rehabilitation can potentially reduce an individual’s risk of reoffending.
MnSOST-R assigns a weight to each risk and protective factor based on how strongly that factor is associated with sexual reoffending. The total score on the MnSOST-R is then calculated by adding up all the weights for all of the risk and protective factors. Offenders who score 0-3 are considered to be at low risk of reoffending, offenders who score 4-6 are considered to be at moderate risk of reoffending, offenders who score 7-9 are considered to be at high risk of reoffending, and offenders who score 10-16 are considered to be at very high risk of reoffending. The assessment’s outcome helps inform decisions related to supervision, treatment, and release planning.
What is the Accuracy of MnSOST-R?
Assessing the accuracy of risk assessment tools like MnSOST-R is a critical aspect of their effectiveness in the criminal justice system. Studies have examined the predictive accuracy of MnSOST-R, and while it is considered a valuable tool, it is not without limitations.
MnSOST-R has shown reasonably good accuracy in distinguishing between higher and low-risk offenders, with higher scores generally associated with an increased likelihood of reoffending. However, like all risk assessment tools, it is not infallible and can sometimes yield false positives or false negatives. In a study of over 5000 sex offenders released from prison in Minnesota, the MnSOST-R predicted 75% of the sex offenders who reoffended within 4 years of release.
One limitation of MnSOST-R is that it may overpredict the risk of reoffending in some cases. This means that some individuals categorized as high risk may not actually go on to reoffend. This has raised concerns about the potential for overly restrictive and punitive measures being applied to individuals who pose a lower risk than indicated by the assessment.
Conversely, MnSOST-R may also fail to identify some individuals who do go on to reoffend, leading to false negatives. Such errors can have serious consequences for public safety, as they result in the premature release or inadequate supervision of potentially dangerous individuals.
It’s essential to recognize that risk assessment tools like MnSOST-R are just one part of a broader assessment process. They should be used in conjunction with clinical judgment and other relevant information to make well-informed decisions about sex offender management.
Courtroom Admissibility of MnSOST-R Results
Numerous state courts have held sex-offender risk assessment results based in part on actuarial testing, like the MnSOST-R, is generally accepted within the scientific community and sufficiently reliable to be admissible when considering the future risk of a sex offender to reoffend. Such states include: Arizona, California, Florida, Illinois, Iowa, Kansas, Massachusetts, Minnesota, Montana, Missouri, Nebraska, New Jersey, New York, North Dakota, Ohio, Oregon, South Carolina, Texas, Washington and Wisconsin.

The Impact of MnSOST-R on Sex Offender Rehabilitation
While MnSOST-R primarily serves as a risk assessment tool, its impact extends to the field of sex offender rehabilitation. By identifying dynamic factors associated with reoffending, this assessment tool can help shape treatment plans and interventions aimed at reducing the risk of future offenses.
For individuals categorized as high risk, MnSOST-R results may trigger more intensive supervision and treatment interventions. This might include participation in specialized sex offender treatment programs that address issues such as distorted sexual thinking, empathy deficits, and relapse prevention. These programs are designed to reduce the likelihood of reoffending by addressing the underlying causes of sexual offending behavior.
In contrast, individuals categorized as low risk may receive less intensive supervision and may not be required to participate in specialized sex offender treatment programs. Instead, they may focus on reintegration into the community, which can involve finding stable housing and employment, strengthening family relationships, and addressing any other needs that could contribute to successful reintegration.
Ethical Considerations and Criticisms of MnSOST-R
While MnSOST-R plays a crucial role in sex offender management, it is not without its ethical considerations and criticisms. Some of the key ethical concerns and criticisms include:
1. Stigmatization: The use of risk assessment tools like MnSOST-R can contribute to the stigmatization of sex offenders, making it difficult for them to reintegrate into society and rebuild their lives.
2. Racial and Gender Bias: Critics argue that risk assessment tools may be biased against certain racial and gender groups, leading to disparities in the criminal justice system. The MnSOST-R was developed on a sample of male sex offenders. It is not clear how well the MnSOST-R predicts sexual recidivism in female or juvenile sex offenders.
3. Limited Focus: Risk assessment tools primarily focus on the risk of reoffending and may not adequately address other important aspects of rehabilitation and reintegration, such as mental health treatment and community support.
4. Potential for Overreliance: There is a risk that criminal justice professionals may rely too heavily on risk assessment tools like MnSOST-R, potentially overlooking individual factors and circumstances that could impact an offender’s risk profile.
5. Lack of Transparency: Some critics argue that the algorithms and methodologies used in risk assessment tools are not always transparent, making it difficult to assess their validity and accuracy.
It’s essential to consider these ethical concerns and criticisms when using MnSOST-R and similar tools in the criminal justice system. Professionals must balance the need for public safety with the principles of fairness, justice, and rehabilitation.
My Final Thoughts
The Minnesota Sex Offender Screening Tool-Revised (MnSOST-R) is a valuable tool in the assessment and management of sex offenders. By considering a range of historical, static, and dynamic factors, it helps professionals make informed decisions about supervision, treatment, and release planning. While MnSOST-R has demonstrated reasonably good predictive accuracy, it is not without limitations, and its use should be complimented by clinical judgment and a holistic approach to rehabilitation.
It’s important to note that the MnSOST-R is not perfect. It is only as accurate as the information that is entered into it. Additionally, the MnSOST-R was developed on a sample of male sex offenders. It is not clear how well the MnSOST-R predicts sexual recidivism in female sex offenders or juvenile sex offenders.
