Coding Rules for Static-2002
Static-2002 is an actuarial risk tool for evaluating the risk of sexual and violent
recidivism among adult male sexual offenders (Hanson & Thornton, 2003). Like
Static-99, Static-2002 can be used by a wide range of evaluators (e.g.,
psychologists, probation officers, psychiatrists, therapists) using commonly
available criminal history information. Static-2002 predicts sexual, violent, and
any recidivism as well as other actuarial risk tools commonly used with sexual
offenders (Hanson & Morton-Bourgon, 2009) and slightly better than Static-99
(Hanson, Helmus, & Thornton, in press; Helmus, 2007).
One desirable feature of Static-2002 is that it is intended to assess some
theoretically meaningful characteristics presumed to be the cause of recidivism
risk (persistence of sexual offending, deviant sexual interests, general
criminality).
The current document describes the scoring rules for Static-2002. These rules
were created from the rules used in the development and validation studies; in
addition, consensus opinion was used to elaborate the rules to cases and legal
jurisdictions different from those previously encountered.
The extent to which readers of this document will be able to appropriately use
Static-2002 is unknown, and would likely vary based on prior training in risk
assessment and specific competence in the use of actuarial risk tools. The
chance of appropriate use should increase given formal training as well as
ongoing procedures to limit rater drift (e.g., peer review, case meetings).
Target population
Static-2002 is designed to be used with certain sexual offenders:
(a) Males who have been convicted of a sexual offence (or received an
equivalent sanction that qualifies as a sentencing occasion in Item 2 of
Static-2002, pages 15-17).
(b) Males who committed their most recent sexual offence after their 18 th
birthday.
(c) With caution, males who committed their most recent sexual offence
between their 17 th and 18 th birthday, provided that their release date is
when they are at least 18. The release date is either the date of release
from a closed custody sentence (in Canada, closed custody is analogous
to prison) or the date of sentence for a community sentence or open
custody sentence (in Canada, open custody is analogous to a halfway
house).
(d) The cautionary note for (c) does not change even if the juvenile offender
was “waived into adult court,” a procedure allowed in some jurisdictions on
