Professionals at all levels of the criminal justice system make decisions that impact offenders. Assistant Professor Maaike Helmus develops tools, called offender risk assessment scales, to ensure these decisions meet empirically guided principles. This ensures more accurate, transparent and fair decisions for offenders. She also delivers risk assessment training internationally to ensure proper use of these scales.

鈥淲e find that structured risk assessment methods are more accurate in predicting reoffending than a professional鈥檚 opinions about the offender. Every decision we make impacts the offender, and potentially impacts public safety, and we have a responsibility to make these decisions as unbiased and effective as possible,鈥� says Helmus.

Helmus is on the development team for the Static-99R, the STABLE-2007 and the ACUTE-2007; these scales are the most frequently used tools globally to assess sexual offenders for probability to reoffend. She recently joined the development team for the first risk assessment scale for child pornography offenders called the Child Pornography Offender Risk Tool (CPORT), and for the Violence Risk Appraisal Guide-Revised, a scale used for violent offences generally.

Helmus wants to improve these risk assessment scales for Canada鈥檚 Indigenous people. In June 2018, the Supreme Court of Canada asked researchers to determine if risk assessment scales accurately apply to Indigenous offenders. Most risk assessment scales predict reoffending worse for Indigenous offenders than non-Indigenous offenders.

鈥淲e have no real idea why this happens. It鈥檚 likely a combination of discrimination and prejudice in the system, and unique cultural differences that our scales are not doing a good job of assessing. That鈥檚 why it鈥檚 complicated. The risk assessment scales are not working as well as we want, but to throw them out, that could do more harm鈥� says Helmus. 颅颅颅颅

Risk assessment scales may be protective by preventing further discriminatory assessments with Indigenous offenders. Helmus finds that when professionals use their own judgement without scales they over estimate risk for Indigenous offenders.

鈥淭he goal is higher accuracy. Structured risk assessments increase accuracy and consistency. You don鈥檛 want someone鈥檚 risk results to be based on which particular psychologist did their assessment. You want methods of assessment to be applied consistently no matter who鈥檚 doing the evaluation. Moving forward, we need to be humbler and more cautious, while understanding the current limitations of the research, when assessing Indigenous offenders,鈥� says Helmus.

Dr. Maaike Helmus joined 丁香园AV鈥檚 School of Criminology in September 2018. She holds a PhD in Forensic Psychology from Carleton University in Ottawa. Her dissertation titled, Developing and Validating a Risk Assessment Scale to Predict Inmate Placements in Administrative Segregation in the Correctional Service of Canada, won the Governor General鈥檚 Gold Medal for graduate work in 2015. Her research focuses include Offender risk assessment; sex offenders; statistics; prediction; recidivism; Indigenous offenders; meta-analysis.

Dr. Maaike Helmus primarily teaches research methods and statistics courses, seminars on offender risk assessment, and psychological perspectives on criminal behaviour. When Dr. Helmus is not in the office, she鈥檚 working from home with her two cats, Cr猫me Brule and Cupcake snuggled at her feet.
