Static-2002 coding rules (2009) - Static-99

information can be used to count these as sentencing occasions, provided that
the self-report information is sufficient to determine that the events in question
meet the definition of a sentencing occasion based on Clear and Convincing
Evidence (see page 7-8 for further explanation of Clear and Convincing
Evidence). Static-2002 should not be scored, however, in the absence of an
official criminal record.
Victim Information
The Static-2002 contains four items requiring information on the victims: “Any
Male Victim,” “Young, Unrelated Victims,” “Any Unrelated Victim,” and “Any
Stranger Victim.” For each of the offender’s sexual offences the evaluator must
know the pre-offence degree of relationship between the victim and the offender.
To score these items evaluators may use any credible information at their
disposal (including self-report) except the polygraph interview or the polygraph
examination.
Polygraph Information
Information derived solely from polygraph interviews or examinations (for
example, information on victims or offence motivation) is not used to score Static-
2002 unless it can be corroborated by outside sources or the offender provides
sufficient information to support a new criminal investigation. This includes all
disclosures made in preparation for a specific polygraph exam. For example, if
the offender completes a sexual history questionnaire that he knows he will be
specifically polygraphed about, or if he is being interrogated under an explicit
threat of being polygraphed, this information would be excluded. Note that this
applies to specific information and an impending polygraph examination.
Information from disclosures made in a treatment group would not be excluded,
even where there may be a polygraph on something at some later point in time.
Information from polygraph interviews is excluded even if the offender talks
generally about the same “polygraph-based” information during later
conversations such as during treatment groups. For instance, if a “male victim” is
discovered solely during a polygraph interview, and there is no independent
source of that information to be found, then this potential “male victim” does not
count on Static-2002.
The reason that polygraph information is excluded is that such information was
not used in the development and validation of Static-2002. Polygraph assisted
disclosures typically provide greater diversity of victim types than gleaned from
other sources; consequently, routinely including information from polygraph
would inflate the scores compared to the procedures used to score Static-2002 in
the development and validation samples.
