In this brief presentation, David Thornton will talk about the need to use multiple static actuarial instruments in carrying out psychosexual assessments to aid sentencing, prioritize treatment approaches, or in the context of potential SVP commitment.
Common practice has been to use a single instrument to assess the static component of risk. However, there are now three, robustly validated, static actuarial instruments: the Static-99R, the Static-2002R, and the Risk Matrix 2000. Comparing them indicates that it is not uncommon for them to assign quite different levels of risk. A person might be in the Average category on one instrument, the Above Average category on a second instrument, and the Well Above Average category on a third. These differences are large enough to have important practical implications.
This presentation will explain this inconsistency and present practical strategies for producing an assessment that better reflects the risk of the person being assessed.
