Millhaven's specialized sex offender intake assessment: A preliminary evaluation
The Millhaven Sex Offender Assessment Service was established in 1993 in direct response to recommendations made to the Correctional Service of Canada.(2) Millhaven Institution is the Service's reception and assessment unit for most of Ontario's federally sentenced offenders and was, therefore, a logical location for a sex offender intake assessment service.Official information is also used to determine the offender's typology.
Most typologies are based on both offender and victim characteristics,
such as number of victims, victim gender and victim age. Categorical scales
are also used to rate degree of physical violence and sexual intrusion.
A comparable offender description of the offence immediately follows the
official version. The offender's version, including denial or minimization,
is written as the offender presents it - without interpretation. This
information is vital in preparing scales such as the Denial and Minimization
Checklist(3) and for some aspects of the risk measures mentioned
earlier. Risk evaluation Three well-known scales are used to evaluate
each offender for risk of recidivism. For example, case managers routinely
complete the General Statistical Information on Recidivism Scale.(4)
This scale score and its standardized interpretation are used for comparison
purposes and as a predictor of general recidivism.
The Level of Service Inventory (Revised)(5) is also used. Offender
total scores and the likelihood of recidivism according to that score
are used to measure the risk of general recidivism. This inventory has
been shown to have dynamic predictive validity.
The Psychopathy Checklist (Revised) is, perhaps, the foremost predictor
of violent recidivism, and its use is also well established with sex offender
populations.(6) Psychopathy Checklist scores are presented
according to cutoffs.(7) Treatment program triage The Service's
Ontario Region provides treatment for minimum-, medium- and maximum-security
sex offenders. The Regional Treatment Centre (Ontario) deals with offenders
of all security levels and offers two sex offender treatment programs
- a group program designed for relatively high-functioning offenders,
and an individualized program designed for lower-functioning or psychiatrically
disturbed offenders.
The Kingston Penitentiary Satellite Sex Offender Program treats maximum-
security offenders, while the Warkworth Sexual Behaviour Clinic works
with medium-security offenders. The Bath Sex Offender program deals with
offenders who have moved down from higher security levels, many of whom
have received treatment in other programs. The Bath program also works
with low- to moderate-risk sex offenders.
Finally, the Pittsburgh Sex Offender Program works with low-risk sex offenders
placed directly into minimum security after assessment at Millhaven. Each
minimum-security institution also operates a relapse prevention program.
Part of the Millhaven assessment report is a recommendation as to the
offender's need for sex offender programming and the most suitable program
for his risk/need profile. The offender is then placed on the waiting
list for that program (see Figure 1).

Computerized information system A comprehensive information database was developed for use with Ontario Region sex offenders. The information included in the database responds to the needs of administrators, clinicians and researchers. Program evaluation Millhaven's Sex Offender Assessment Service can be said to affect five stakeholder groups:

The stakeholders were asked to evaluate the six mentioned services provided by Millhaven's Sex Offender
Assessment Service by indicating the degree of improvement over previous procedures, using ratings
ranging from worse to much improved. Respondents were also asked to propose improvements. If they were
unfamiliar with one of the functions, respondents were to leave that area blank. Few respondents left
areas blank and none rated the services as worse.
More than 65% of the respondents rated Millhaven's sex offender identification process as much improved
over previous procedures (see Figure 2). Only a few added comments on this topic, with most supporting
the rating or praising Millhaven's capacity to identify sex-related offences.
Figure 2
Millhaven's assessment reports were viewed as much improved by 78% of respondents. All respondents
rated this item, presumably because they had all used the reports. Only one respondent rated the reports
as not improved. Most comments on this topic were positive, but there were a few constructive
criticisms. For example, three Millhaven case management officers pointed out that the criminal profile
reports contain largely the same information as the criminal history section.
Millhaven's risk evaluations were viewed as much improved by 63% of respondents. However, the comments
on this item were far more critical - although still constructive. A couple of psychologists suggested
that raw scores be presented, especially for the Psychology Checklist, so that they could apply their
own cutoffs. Several case managers also questioned the use of phallometric measures.
Millhaven's treatment recommendations for offenders were viewed as much improved by 66% of respondents.
The critical comments came exclusively from case management staff. Virtually all of these comments
advocated explaining why a particular program was recommended for a specific offender.
Millhaven's recommendations of particular institutions for offenders were also viewed as much improved
by 66% of respondents.
However, Millhaven case managers pointed to instances of duplication, and case managers from other
institutions questioned the degree of consultation between the assessment service and Millhaven's case
management officers.
The number of blank areas in the computerized information system section indicates that several
respondents were either unaware of, or had not come into contact with, this system.
However, the stakeholders who had come into contact with the system tended to rate it as improved.
Respondents with computer network access made the most positive comments, but did cite system slowdowns
as problematic. Recommendations The results of this preliminary evaluation of Millhaven's Sex Offender
Assessment Service are clearly quite positive. The five stakeholder groups rated all of its services as
much improved over the sex offender assessment services previously offered.
However, there is always room for improvement, so several changes have been made or recommended.
The duplication of effort in the criminal profile reports (compiled by case management staff) and the
criminal histories (compiled by behaviour analysts) is being addressed through a project to combine
these two areas of responsibility. Offender intake assessments and specialized sex offender assessments
will become the responsibility of Sex Offender Assessment Services.
The computerized tracking and information system has also now been expanded to all institutions and two
district offices in Ontario Region. As more people learn to use it, the system will probably further
expand.
This preliminary evaluation indicates that the Millhaven Sex Offender Assessment Service could be
categorized as a success. With relatively minor changes, it could serve as a model that other Service
regions may wiszh to follow.
